Comparative transcriptome analysis identified crucial genes and pathways affecting sperm motility in the reproductive tract of drakes with different libido.

Libido can affect the semen quality of male, and the sperm motility in semen quality parameters is a reliable index to evaluate the fertility of male. In drakes, the sperm motility is gradually acquired in testis, epididymis, and spermaduct. However, the relationship between libido and sperm motility in drakes has not been reported and the mechanisms of testis, epididymis, and spermaduct regulating the sperm motility of drakes are unclear. Therefore, the purpose of the present study was to compare the semen quality of drakes with libido level 4 (LL4) and libido level 5 (LL5), and tried to identify the mechanisms regulating the sperm motility in drakes by performing RNA-seq in testis, epididymis, and spermaduct. Phenotypically, the sperm motility of drakes (P < 0.01), weight of testis (P < 0.05), and organ index of epididymis (P < 0.05) in the LL5 group were significantly better than those in LL4 group. Moreover, compared with the LL4 group, the ductal square of seminiferous tubule (ST) in testis was significantly bigger in the LL5 group (P < 0.05), and the seminiferous epithelial thickness (P < 0.01) of ST in testis and lumenal diameter (P < 0.05) of ductuli conjugentes/dutus epididymidis in epididymis were significantly longer in the LL5 group. In transcriptional regulation, in addition to KEGG pathways related to metabolism and oxidative phosphorylation, lots of KEGG pathways associated with immunity, proliferation, and signaling were also significantly enriched in testis, epididymis, and spermaduct, respectively. Furthermore, through the integrated analysis of coexpression network and protein-protein interaction network, 3 genes (including COL11A1, COL14A1, and C3AR1) involved in protein digestion and absorption pathway and Staphylococcus aureus infection pathway were identified in testis, 2 genes (including BUB1B and ESPL1) involved in cell cycle pathway were identified in epididymis, and 13 genes (including DNAH1, DNAH3, DNAH7, DNAH10, DNAH12, DNAI1, DNAI2, DNALI1, NTF3, ITGA1, TLR2, RELN, and PAK1) involved in Huntington disease pathway and PI3K-Akt signaling pathway were identified in spermaduct. These genes could play crucial roles in the sperm motility of drakes with different libido, and all data the present study obtained will provide new insights into the molecular mechanisms regulating sperm motility of drakes.

A qualitative analysis of female Reddit users' experiences with low libido: how do women perceive their changes in sexual desire?

BACKGROUND: The true prevalence of low sexual desire among women is disputed among researchers due to the complex nature and presentation of women's sexual problems. AIM: To qualitatively analyze the aspects of libido/sexual desire frequently discussed by Reddit users and compare them with the current understanding of female sexual well-being and sexual desire disorders. METHODS: By using the Reddit application programming interface, the TwoXChromosomes subreddit was queried for posts with the keywords libido and sex drive. Posts that were deleted or unrelated to themes of libido/sex drive were excluded. A total of 85 threads-63 queried from the keyword libido and 22 from sex drive-and approximately 2900 comments were qualitatively analyzed per the grounded theory approach. Five independent researchers read and coded each thread to identify dominant themes and emergent concepts. OUTCOMES: Outcomes of interest included codes related to sexual dysfunction, libido, orgasm, masturbation, types of sex, psychology, relationships, intimacy, treatment, medications, and health care. RESULTS: Posters were primarily heterosexual women in their 20s and 30s. The code categories with the highest frequency were relationships (22.7%, n = 272), libido (22.2%, n = 210), psychological (20.2%, n = 191), medications (7.29%, n = 69), and intimacy (6.0%, n = 57). Users frequently described a decrease in libido secondary to medications, particularly antidepressants and hormonal birth control. Many users discussed the challenges of navigating a relationship with low sexual desire and the resulting sexual distress. Posters described feelings of sadness, anxiety, and guilt due to their low desire. Additionally, users discussed the role that sex plays in relationships, whether as a way to develop intimacy between partners or to achieve orgasm. Finally, posters expressed dissatisfaction with health care addressing their concerns surrounding sexual desire. CLINICAL IMPLICATIONS: The study findings-namely, the impact of medications on sexual health, the interaction of sexual desire and mental health, and cited examples of inadequate sexual health care-can help guide sexual well-being research, diagnosis, and public policy. STRENGTHS AND LIMITATIONS: Using Reddit as a data source allowed for the analysis of women's experiences outside the preestablished concepts of female sexual desire. Limitations to the study include the potential for posts to be deleted by moderator guidelines, the young demographic distribution of Reddit users, and the popularity-based structure of subreddit threads. CONCLUSION: Our results emphasize the psychosocial aspects of sexual desire and the need to redefine sexual problems to encompass the complex nature of female sexual well-being.

Flaxseed oil modulates testicular biometrics, hormone, libido, antioxidant and semen profiles in endangered Teressa goat of Andaman and Nicobar Islands.

Teressa goat is a unique goat breed in Andaman and Nicobar Islands (ANI) of India. Effects of Flaxseed oil (FSO) supplementation in body weight (BW), scrotal circumference (SC), testicular volume (TV) and testicular weight (TW), endocrinological profiles, sex behavioural profiles (SBPs), oxidative stress markers and semen production and its quality profiles in rainy and dry summer season were studied in Teressa goat. Male goats (n = 12) of 3-4 years old were equally divided into control and treated groups. Treated animals received 25 mL FSO per day. Oral drenching of FSO was done in the morning before feeding the concentrate ration. Body weight, scrotal circumference, TV and TW were measured in bucks of FSO treated and untreated during rainy and dry summer seasons. Blood follicle stimulating hormone (FSH), luteinizing hormone (LH), testosterone, thyroid stimulating hormone (TSH), triiodothyronine (T3), thyroxine (T4), cortisol and prolactin, total antioxidant capacity (TAC), superoxide dismutase (SOD), catalase (CAT), glutathione (GSH) and malondialdehyde (MDA) were measured in bucks of FSO treated and untreated during rainy and dry summer seasons. Libido score (LS), mating ability score (MAS) and sex behavioural score (SBS) were estimated at time of semen collection in bucks of FSO treated and untreated during rainy and dry summer seasons. Semen samples (n = 100; 50 semen samples from each season; each 25 semen samples from control and treatment groups per season) were collected and analysed for semen quality profiles. One-way ANOVA (control rainy, control dry, treated rainy and treated dry) revealed that BW, SC, TV and TW, FSH, LH, testosterone, TSH, T3 and T4 were higher (P < 0.05) and cortisol and prolactin were lower (P < 0.05) in FSO treated bucks of rainy season followed by untreated bucks of rainy season, FSO treated bucks of dry summer season and were lower (P < 0.05) in untreated bucks of dry summer season. Similarly, TAC, CAT, SOD and GSH, LS, MAS and SBS, and volume, pH, sperm concentration, mass activity, total motility (TM), viability, acrosomal integrity (AcI), plasma membrane integrity (PMI) and nuclear integrity (NI) were higher (P < 0.05) and MDA and TSA were lower (P < 0.05) in FSO treated bucks of rainy season followed by FSO treated bucks of dry summer season, untreated bucks of rainy season and were lower (P < 0.05) in untreated bucks of dry summer season. The results of the present study indicated that the breeding bucks suffered physiological stress (higher cortisol), oxidative stress (higher MDA and deficiency of antioxidants), hormonal imbalance (higher prolactin and cortisol and deficiency of gonadotropins, gonadal hormone and thyroid hormones) and infertility due to poor libido and poor semen production and its quality profiles during dry summer season. Thus, dry summer was more stressful season compared to rainy season for the goat bucks. FSO supplementation mitigated these stresses and improved the scrotal and testicular biometrics, libido, antioxidants, hormones and semen quality profiles in Teressa goat bucks. The current study concluded that FSO effectively improved the hormones, libido, antioxidant profiles, and scrotal and testicular biometrics with cascading beneficial effects on semen quality profiles in Teressa goat bucks under humid tropical island ecosystem of Andaman and Nicobar Islands.

Lifetime and removal reasons for Pietrain boars in European AI centers: a retrospective analysis.

Currently, artificial insemination (AI) is the most common reproductive method used in swine production. The economic profitability of AI centers is closely linked to a boar's retention rate and the purchase of replacement boars. The objectives of this study were to examine data of selection process and lifetime of a total of 6,496 purebred Pietrain AI boars and to analyze the frequency and reasons of removal in eight European countries. Data were obtained from two German boar multiplication farms as well as 53 AI centers from 2018 to 2022. The retention time was analyzed from the selection process until replacement and to the end of the examination, respectively. The selection process of the boars took place at 168 ±â€…5 (mean ±â€…SD) days of age. For further calculations, the removal reasons were divided into nine groups: breeding (BR), died (DI), euthanasia (EU), health (HE), genetics (GE), low libido (LI), sperm quality (SQ), structure (ST), and other (OT). Overall, 56.1% of the examined boars were removed, with 17.5% being removed within the same year they entered the AI center. The annual removal rate for the 53 AI centers averaged 42.4%. The most frequent removal reason was low SQ (45.1%), followed by genetics (28.6%) and low libido (10.6%). The highest relative frequency of removals was observed for an age of 2 yr (34.0%). The highest removal risk was calculated for boars in Czech AI centers (P < 0.001), while the lowest removal risk occurred in Dutch (P = 0.006) and Portuguese AI centers (P = 0.01). The comparison of removal groups revealed, inter alia, higher body weight at selection process for the BR group (117.9 ±â€…9.0 kg) and longer quarantine periods for LI group (45.9 ±â€…17.6 d). Boars in the GE group were characterized by the oldest age at removal (934.0 ±â€…272.8 d) and longest period of exploitation (672.5 ±â€…266.8 d). The results could be helpful to detect the most common reasons for production failure of AI Pietrain boars and beneficial for establishing an economical removal policy in AI centers and for improving boar management through problem-based selection in boar multiplication farms.

Unsurprisingly, the removal of boars from artificial insemination (AI) centers affects the centers' economic performance and production efficiency. An analysis of reasons for removal is beneficial for an optimal removal policy and can help detect health problems that could be occurring in the herd. The aim of this study was to analyze data of selection process and removal, lifetime and removal reasons of 6,496 Pietrain boars in 53 European AI centers. The most common reason for boar removal was poor sperm quality, followed by genetics and low libido. The highest retention rate with increasing age was calculated for boars removed due to genetics, whereas boars removed because of low libido were characterized by the lowest probability to remain in the herd. Hazard analysis indicates that the removal risk for boars is influenced by the production process and differs between European countries.

THE ANALYSIS OF THE IMPACT OF THE TYPE OF CONTRACEPTION USED BY WOMEN ON THE LEVEL OF THEIR SEXUAL SATISFACTION AND COMFORT OF USE.

OBJECTIVE: The aim: To compare satisfaction of women using oral contraception to satisfaction of women using the levonorgestrel-secreting intrauterine system. In the comparison the following factors were taken into account: comfort of use, menstrual cycle, libido level, well-being and the impact on the relationship with a partner. PATIENTS AND METHODS: Materials and methods: The study involved 129 randomly selected women who had to fill in the research survey questionnaire. RESULTS: Results: It has been proved that patients are more willing to use the intrauterine system secreting levonorgestrel because of a more reliable contraceptive effect and convenience of use. This kind of contraception has a beneficial effect on libido and relationships with a partner. Women using oral contraception did not report such advantageous influence of their method of contraception. An increase in libido was noticed for 24 women in the group of patients using the levonorgestrel-secreting intrauterine system and for 8 women in the group of users of oral contraception, which corresponds to 33.8% and 13.8%. Patients used oral contraception more often in order to regulate their menstrual cycle and to reduce heavy menstrual bleeding. CONCLUSION: Conclusions: The study identifies groups of women for whom a specific method of contraception would be appropriate. The greatest benefits of using the levonorgestrel-secreting intrauterine system will have patients who appreciate the convenience of use, as well as those who have sex drive disorders or for whom oral contraception causes undesirable symptoms. Women with hormonal disorders, irregular menstrual cycles and heavy menstrual bleeding will benefit most from the use of oral contraception.

[Evaluation of sexual issues by professionals who assist type 2 diabetic men]. / Evaluación de temas sexuales por profesionales que asisten a hombres con diabetes tipo 2.

INTRODUCTION: Our objective was to assess whether physicians who care for people with type 2 diabetes address andrological symptoms such as erectile sexual dysfunction, decreased libido, and symptoms and/or signs of hypogonadism. METHODS: An anonymous survey was carried out with 171 doctors, 113 were females (66.1%), the mean age was 46 ± 10 years (females: 45 ± 10 and males: 49 ± 10, p = 0.006). RESULTS: There were no differences in responses according to gender. Regarding the presence of erectile sexual dysfunction and/or decreased libido, 44.4% (n = 76) and 55.6% (n = 95) did not ask about them, respectively. In patients with symptoms of hypogonadism, 50.9% (n = 87) did not request a testosterone measurement. Regarding the improvement of the metabolic profile of type 2 diabetes mellitus and sexual symptoms after replacement with testosterone, 65.8% of the respondents answered that both conditions could improve after treatment. In the presence of symptoms compatible with hypogonadism, 74.7% of those surveyed stated that the measurement of testosterone should be performed. A total of 108 (63.2%) showed interest in being trained on topics related to type 2 diabetes and disorders of the sexual sphere. CONCLUSION: A large percentage of physicians who take care of men with type 2 diabetes do not inquire about andrological disorders. It is necessary to raise awareness and train doctors to detect, treat and/or refer these frequent health problems, not only to improve the quality of life of patients but also to effectively respond and prevent a major health problem.

Introducción: Los trastornos andrológicos son frecuentes en varones con diabetes tipo 2. El objetivo fue evaluar si los médicos que atienden a personas con diabetes tipo 2 abordan problemas andrológicos como disfunción sexual eréctil, disminución de libido y síntomas de hipogonadismo. Métodos: Se llevó a cabo una encuesta anónima a 171 médicos, de ellos 113 fueron mujeres (66.1%) con una edad media de 46 ± 10 años (mujeres: 45 ± 10 y varones: 49 ± 10, p = 0.006). Resultados: No hubo diferencias en las respuestas según el género. El 44.4% (n = 76) y el 55.6% (n = 95) no preguntan sobre la presencia de disfunción sexual eréctil y/o disminución de libido, respectivamente. El 50.9% (n = 87) no solicitó medición de testosterona en pacientes con síntomas de hipogonadismo. El 65.8% de los participantes respondió que el reemplazo con testosterona puede mejorar el perfil metabólico de la diabetes mellitus tipo 2 y los síntomas sexuales. El 74.7% de los encuestados afirmó que la medición de testosterona debería realizarse ante la presencia de síntomas compatibles con hipogonadismo. El 63.2% (n = 108) mostró interés en formación sobre temas relacionados a diabetes tipo 2 y trastornos de la esfera sexual. Conclusión: Un gran porcentaje de médicos que asisten a varones con diabetes tipo 2 no indaga sobre trastornos andrológicos. Es necesario concientizar y entrenar a los médicos, para detectar, tratar y/o derivar estos problemas de salud tan frecuentes, no solo para mejorar la calidad de vida de los pacientes sino para responder y prevenir efectivamente a un problema mayor de salud.

Determinants of sexual function in men living with HIV younger than 50 years old: Focus on organic, relational, and psychological issues.

BACKGROUND: Sexual dysfunctions, particularly erectile dysfunction, are common in men living with HIV, whose organic and psychological components remain to be clarified. The aim of the study is to investigate the impact of risk factors of sexual dysfunctions, including organic, relational, and psychological determinants of erectile function, in men living with HIV younger than 50 years old. METHODS: A cross-sectional, observational study was conducted in men living with HIV < 50 years. The questionnaire International Index of Erectile Function-15 was used to assess the prevalence and degree of erectile dysfunction. The structured interview of erectile dysfunction was used to explore the organic (Scale 1), relational (Scale 2), and psychological (Scale 3) components of erectile dysfunction. Total testosterone, estradiol, and dihydrotestosterone were measured by liquid chromatography-tandem-mass spectrometry; free testosterone was calculated by the Vermeulen equation. RESULTS: A total of 313 consecutive men living with HIV were prospectively enrolled (median age 47.0 years; median HIV-infection duration 16.2 years). 187 patients (59.7%) had erectile dysfunction, with a higher prevalence of non-heterosexual (138 out of 187, 73.8%) than heterosexual patients (p = 0.003). Patients with erectile dysfunction showed a worse score of structured interview of erectile dysfunction scale 3 compared to patients without erectile dysfunction (p = 0.025); the International Index of Erectile Function-15 was inversely related to structured interview of erectile dysfunction scale 3 (p = 0.042). No difference was found for sex steroids (total testosterone, estradiol, free testosterone, and dihydrotestosterone) between men living with HIV with and without erectile dysfunction. In the multivariate analysis sexual orientation, and lack of stable relationships were major determinants for erectile dysfunction. Only 35 of 187 patients with erectile dysfunction (18.7%) reported the use of erectile dysfunction medications. CONCLUSIONS: Within the multidimensional network of erectile dysfunction in men living with HIV, the psychological component is predominant, highlighting the contribution of peculiar factors related to HIV distress (e.g., fear of virus transmission, stigma) rather than gonadal status and other classical risk factors. In contrast to the high prevalence, only a few patients reported the use of erectile dysfunction medications suggesting a general under-management of such issues.

Patients' Preferences for Androgen Deprivation Therapy in the Treatment of Intermediate-Risk Prostate Cancer.

Background. For men with intermediate-risk prostate cancer (IRPC), adding short-term androgen deprivation therapy (ADT) to external beam radiation therapy (EBRT) has shown efficacy, but men are often reluctant to accept it because of its impact on quality of life. Methods. We conducted time tradeoffs (score of 1 = perfect health and 0 = death) and probability tradeoffs with patients aged 51 to 78 y who had received EBRT for IRPC within the past 2 y. Of 40 patients, 20 had received 6 mo of ADT and 20 had declined. Utility assessments explored 4 ADT-related side effects: hot flashes, fatigue, loss of libido/erectile dysfunction, and weight gain. Results. The most commonly reported "worst" treatment-related complication of ADT was fatigue (50% in both cohorts) followed by reduced libido/erectile dysfunction (40% in both cohorts). The utilities for fatigue were mean = 0.71 and median = 0.92 and for reduced libido/erectile dysfunction were mean = 0.81 and median = 0.92. Utilities did not differ significantly between cohorts. Assuming a 6-mo course of ADT, men reported being willing to trade 3 mo of life expectancy to avoid fatigue due to ADT and 1.8 mo to avoid sexual side effects. Patients in the ADT cohort were willing to accept the side effects of ADT in exchange for a mean 8% absolute increase in survival, whereas patients in the no ADT cohort required a 16% increase (P < 0.001). Conclusions. When considering treatment with ADT, men with IRPC identified fatigue and sexual dysfunction as the most bothersome side effects. Patients who declined ADT expected a larger survival benefit than those who opted for treatment. Both groups expected a survival benefit exceeding that shown by recent trials, suggesting some men may be selecting treatments inconsistent with their preferences. Highlights: This study demonstrates that prostate cancer patients receiving radiation therapy are reluctant to receive androgen deprivation therapy (ADT) most commonly due to anticipated fatigue and loss of libido/erectile dysfunction.Men who had received ADT reported they would require an average 8% absolute increase in survival to tolerate its side effects, whereas those who declined ADT would require an average 16% increase.Required thresholds are well above the estimated absolute survival benefit for ADT demonstrated in recent clinical trials, suggesting an unmet need for improved patient education regarding the risks and benefits of ADT.

Regulation of male sex hormones strongly heightens copulation behavior indices in rat's model administered Cocos nucifera husks extract.

Background: Cocos nucifera (Coconut, Arecaceae family) is consumed as dietary fruit but little is known of it as sex enhancer. Objective: To investigate male sex hormones and copulation behavior indices in male Wistar rats administered husks extract. Materials and Methods: Rats were grouped into control A, and treatment B to E (n=4); and administered husks extract at varying doses: 125mg/kg, 250mg/kg, 375mg/kg and 500mg/kg for 48days by oral intubation. Copulation behavior was assessed by introducing female rats to males (1:1) in a rectangular Plexiglas chamber and monitored by veterinary Anatomists. Blood samples for male sex hormones were collected and assayed by ELISA method. Results: Copulation behavior (500mg/kg treatment): mounting (9.66±0.79 to 29.08±2.16), ejaculation (7.66±0.38 to 16.93±0.76), intromission (22.01±1.67 to 38.11±3.35) frequencies, and ejaculation latency (7.92±0.43 to 12.28±0.41) increased remarkably (Group E). Correspondingly, mounting (133.31±1.18 to 93.39±0.43) and, intromission (88.13±3.12 to 74.55±1.19) latencies; post-ejaculation (3.16±0.14 to 2.18±0.34), inter-intromission (19.48±0.26 to 14.32±1.65) intervals reduced significantly (P≤0.05). Testosterone levels (Group E) increased: 3.82±0.6ng/dL to 5.14±0.3ng/dL while, LH and FSH values reduced: 2.92±0.6IU/L to 2.13±0.3IU/L and 2.28±0.7IU/L to 1.58±0.3IU/L significantly (p ≤ 0.05) while changes were dose-related. Conclusion: C. nucifera husks extract improves sexuality indices by regulating male sex hormones in male Wistar rats.

Detection, examination and therapy of sexual dysfunctions in patients with diabetes.

Diabetes mellitus is a disease associated with multiple complications due to ineffective diabetes management in the early period after diagnosis and especially in the long term. However, the risk of developing sexual dysfunctions, which affect both men and women, is rarely mentioned in association with diabetes (1). Sexual complications not only disrupt with the social and sexual life of patients, but are often the first symptom of other health problems. For these reasons, in people with diabetes, early detection and proper treatment of sexual dysfunctions should be of concern physicians caring for diabetic patients.

Testosterone and Male Sexual Function.

This article reviews the role of testosterone in normal male sexual anatomic development and function, the consequences of low testosterone on sexual function, and clinical standards for health care providers treating hypogonadal men with sexual dysfunction.

Distended Seminal Vesicles Are Involved in Specific Cerebral Sexual Arousal: A Pilot Study Using Functional Brain Imaging in Young Healthy Men.

Background: Whether seminal vesicles play a role in sexual activity in men is unknown. No study so far has compared the neural processing of visual sexual stimuli in men depending on the filling state of the seminal vesicles. Objective: To evaluate potential specific cortical activation by visual sexual stimuli with distended and empty seminal vesicles. Design setting and participants: A prospective case-control trial was conducted. Six male individuals underwent two visits on 2 consecutive days for hormone analyses; Derogatis Interview for Sexual Functioning (DISF) questionnaire; functional magnetic resonance imaging (fMRI) with passively viewing sexual, neutral, positive, and negative emotional pictures; and structural pelvic MRI. After the first visit, the participants had to empty seminal vesicles by masturbation. During fMRI, every participant viewed alternating blocks of sexual, neutral, positive, and negative emotional pictures. Outcome measurements and statistical analysis: Comparisons between days 1 and 2 were evaluated using paired t tests. Results and limitations: No significant differences were observed regarding hormone analyses, DISF questionnaire score, and arousal scoring between days 1 and 2. Seminal vesicle volume was significantly lower on day 2 (p = 0.003). Significantly higher activation was observed in the right precentral gyrus, middle frontal gyrus, and right superior temporal sulcus when contrasted for sexual over neutral (p < 0.05). Conclusions: In response to pictures with sexual emotional content, significantly higher activation was detected in brain areas involved in motor preparation (arousal) and coding of desirability of visual sexual stimuli in men with distended seminal vesicles than in the same men with emptied seminal vesicles. This suggests that the filling state of the seminal vesicles may influence sexual desire in men. Patient summary: We compared brain activity of men with filled and emptied seminal vesicles by functional magnetic resonance imaging. We found that men with filled seminal vesicles had higher activation of brain areas involved in arousal and sexual desire.

Infertility In Toms: Clinical approach, experiences and challenges.

PRACTICAL RELEVANCE: An infertile tom used to be a relatively rare presentation in feline practice. However, as a result of breeding strategies targeting specific morphological/behavioural traits, and the influence of inbreeding (especially practised in rare breeds), among other factors, feline infertility has become a genuine clinical problem. Furthermore, increased interest among cat breeders and pet owners in diagnosing and treating an 'unsuccessful' tom (including using assisted reproductive techniques [ARTs]), has made such patients more commonplace in veterinary practice. CLINICAL CHALLENGES: A definitive cause for male infertility is often difficult to identify. One of the biggest challenges is the lack of fertility-based reference values for semen quality and hormone levels. Moreover, the literature in this field is scant and many reproductive tract conditions described in other species have not been reported in cats. The establishment of diagnostic tools and algorithms is essential to facilitate a reliable assessment of fertility potential. GLOBAL IMPORTANCE: There is a growing demand for appropriate veterinary care relating to feline reproduction. There is an expectation among breeders, particularly of pedigree cats of high breeding value, that the same options widely used for dogs (including ARTs) should also be available for cats. EQUIPMENT AND TECHNICAL SKILLS: Equipment required for investigating male infertility includes a microscope and ultrasound machine; a blood analyser may also be useful, but samples can instead be sent to a laboratory. The skills required are often already performed by veterinarians; for example, catheterising the urethra, performing ultrasonography and blood sampling. EVIDENCE BASE: There are some reports of fertility problems in male cats in the literature, but this area of feline reproduction is still relatively undeveloped. This review draws on the comprehensive knowledge developed and shared by specialists in this field, and is supported by the authors' own clinical experience.

Sexual dysfunction among males and females with bipolar disorder and healthy subjects: The burden of illness severity.

OBJECTIVES: Sexual dysfunction has wide-ranging impacts on the person's functioning and quality of life, being associated with higher severity of psychiatric illnesses and poor therapeutic response. Given the paucity of data on this topic in bipolar disorder (BD), we investigated sexual functioning among males and females with BD and healthy controls (HCs) as well as whether illness severity markers and subthreshold mood symptoms were associated with sexual dysfunctions in BD patients. METHODS: The study included 80 BD outpatients and 70 HCs. Sexual functioning was evaluated using the validated, gender-specific Changes in Sexual Functioning Questionnaire (CSFQ-14). RESULTS: BD patients had a significantly poorer sexual functioning than HCs (p < 0.00001). The odds of sexual dysfunction doubled given a one-unit increase in the number of suicide attempts (adjusted OR = 2.01, 95% CI:1.23-3.55; p < 0.01) and increased by 60% for every additional hospitalization (p < 0.05). Greater illness duration was associated with arousal/orgasmic (p < 0.05) and overall sexual dysfunctions (p < 0.01). BD patients with more mixed or (hypo)manic episodes had a lower likelihood of libido loss and arousal/orgasmic disturbances (p < 0.01), respectively. Higher levels of subthreshold depressive symptoms increased by 20% the odds of sexual interest/frequency dysfunctions (p < 0.05), and up to 60% regarding orgasmic disturbances (p < 0.01). CONCLUSIONS: Sexual functioning may be a useful proxy of illness severity as well as a relevant dimension to more deeply characterize BD patients. Further studies are warranted to replicate our findings, to evaluate temporal associations between sexual dysfunctions and illness severity across the BD mood and treatment spectrums and to explore neurobiological underpinnings of these associations.

Is generativity Erikson's answer to human ageing in the neoliberal world?

This paper uses the concept of generativity to challenge the ageist view of older adults' reduced social and economic contributions in a neoliberal economy and support an age-integrated society. It revisits Erik Erikson's life cycle theory and brings forth the argument that the core quality of the seventh stage of human ego development, generativity vs stagnation, transverses all previous developmental stages and creates a forever-moving life cycle through intergenerational connections. Generativity is critical to human ageing as it is closely linked to notions of transfer of knowledge. This paper investigates generativity in relation to ego, libido and ageing. It discusses the ego as the medium of generativity and libido as its source of energy. It also explores how opportunities for intergenerational exchange, transfer of knowledge, and creativity are fashioned to suit the larger economic and socio-cultural context through sublimation. The paper concludes that generativity is the most promising route to an age-friendly society.

Mixed Study Systematic Review and Meta-analysis of Sexuality and Sexual Rehabilitation in LGBTQI+ Adults Living With Chronic Disease.

OBJECTIVE: To systematically review how sexuality is experienced by lesbian, gay, bisexual, transgender, queer or questioning, intersex plus (other gender identifies and sexual orientations) (LGBTQI+) persons living with chronic disease. DATA SOURCES: PsycINFO, Embase, MEDLINE, Scopus, Cumulative Index to Nursing and Allied Health, and Web of Science were searched from date of inception to November 2021 for English language publications. Reference lists of relevant publications were also searched. STUDY SELECTION: Eligible studies reported on sexuality among LGBTQI+ persons living with chronic disease. The search yielded 12,626 records; 665 full texts were assessed for eligibility and 63 documents included (59 unique studies). Study quality was rated using the Mixed Methods Appraisal Tool. DATA EXTRACTION: Characteristics of included studies were recorded independently by 2 authors. Differences were resolved through discussion or with a third author. DATA SYNTHESIS: A sequential, exploratory mixed-studies approach was used for synthesis. Pooled analysis indicated that among gay and bisexual men living with prostate cancer, 68.3% experienced erectile dysfunction and 62.9% had insufficient quality of erection to engage in anal sex. Among gay and bisexual men living with HIV or AIDS, 29.3% experienced loss of libido and 25.3% experienced erectile dysfunction. Although sexual dysfunction was common, LGBTQI+ persons had difficulty accessing appropriate sexual counseling and identified negative attitudes and heteronormative assumptions by health care providers as significant barriers to sexual health. Interventions to address sexuality focused entirely on reduction of risky sexual behavior among men living with HIV or AIDS. Women, transgender persons, and intersex persons were largely excluded from the research studies. CONCLUSIONS: Current understandings of the effect of chronic disease on LGBTQI+ sexuality are limited and mostly focus on the male sexual response. LGBTQI+ persons who experience difficulty with sexuality struggle to identify appropriate services, and there is an absence of evidence-based interventions to promote sexual health and well-being in this population.

Psicopatologias atuais e traumatofilias: Libido Intrassomática detectada em avaliação psicológica da personalidade na análise do discurso e protocolos de testes projetivos atualizados / Psicopatologías actuales y traumatofilias: Libido Intrasomática detectada en evaluación psicológica de personalidad en análisis del discurso y protocolos de tests proyectivos actualizados / Current psychopathologies and traumatophilias: intrasomatic libido detected in psychological assessment of personality in discourse analysis and updated projective testing protocols

A avaliação psicológica no Brasil é regida por Instruções Normativas e Resoluções que indicam as características de personalidade necessárias ou impeditivas para diversas áreas laborais, educacionais e sociais. Postulada por Maldavsky, a Libido Intrassomática (LI) é uma fase libidinal onde são originárias as patologias atuais (Patologias do Desvalimento). A LI pode ser detectada no discurso do sujeito e também em testes como o Z-Teste (Burani, 2020 e 2022) e Questionário Desiderativo -QD (Sneiderman, 2012) de acordo com novos aportes teóricos. Objetivo:O objetivo deste artigo é apresentar a Libido Intrassomática detectada em Avaliação Psicológica da personalidade na análise do discurso e protocolos de testes projetivos atualizados, mediante a aplicação do Z-Teste e Questionário Desiderativo e do discurso do avaliado. Material y Métodos:Analisamos 211 protocolos de QD e Z-Teste, e dados de saúde obtidos ementrevista, de homens com idades entre 30 e 60 anos avaliados para uso de armas. Esta pesquisa foi aprovada na Plataforma Brasil, CAAE: 42474920.4.0000.0123 e integra a tese do autor. Resultados:As análises dos protocolos indicaram quais as erogeneidades predominantes nas respostas: LI apareceu em 15% das respostas do Z-teste e em 13% das respostas do QDcatexias positivas e 37% das respostas de QD catexias negativas. Vinculamos esta frequência aos dados de saúde dos avaliados mediante seu discurso, indicando a presença de hipertensão, diabetes, problemas respiratórios, alergias entre outras as patologias atuais de desvalimento, e em na maioria dos casos em adicções etraumatologias ou tendência a acidentes. Conclusões:A detecção de erogeneidades em respostas de testes projetivos permite não só melhor avaliação de características da personalidade, mas a detecção patologias atuais de desvalimento. A presença de LI em avaliação psicológica para o uso de armas de fogo, indica a necessidade de estudos mais profundos quanto às patologias atuais do desvalimento, sobretudo para esta população AU

La evaluación psicológica en Brasil se rige por Instrucciones Normativas y Resoluciones que señalan las características de personalidad necesarias u obstaculizantes para diversas áreas laborales, educativas y sociales. Postulada por Maldavsky, la Libido Intrasomática (LI) es una fase libidinal donde se originan las patologías actuales (Patologías del Desvalimiento). LI se puede detectar en el habla del sujeto y también en pruebas como el Z-Test (Burani, 2020 y 2022) y el Cuestionario Desiderativo -CD (Sneiderman, 2012) según nuevos aportes teóricos. Objetivo:El objetivo de este artículo es presentar la Libido Intrasomática detectada en Evaluación Psicológica de la personalidad en el análisis del habla y protocolos actualizados de pruebas proyectivas, mediante la aplicación del Z-Test y Cuestionario Desiderativo y el habla evaluada. Material y Métodos:Se analizaron 211 protocolos QD y Z-Test, y datos de salud obtenidos en entrevistas, de hombres de entre 30 y 60 años evaluados por uso de armas. Esta investigación fue aprobada por Plataforma Brasil, CAAE: 42474920.4.0000.0123 y es parte de la tesis del autor. Resultados: El análisis de los protocolos indicó qué erogeneidades predominaron en las respuestas: LI apareció en el 15% de lasrespuestas de la prueba Z y en el 13% de las respuestas QD catexias positivas y 37% de las respostas de QD catexias negativas. Vinculamos esta frecuencia a los datos de salud de los evaluados a través de su discurso, indicando la presencia de hipertensión arterial, diabetes, problemas respiratorios, alergias entre otras patologías actuales de desamparo, y en la mayoría de los casos en adicciones y tendencia a accidentes. Conclusiones: La detección de erogeneidades en las respuestas de los test proyectivos permite no solo una mejor valoración de las características de personalidad, sino también la detección de patologías de desvalimento y patologias actuales. La presencia de LI en la valoración psicológica para el uso de armas de fuego indica la necesidad de profundizar en los estudios sobre las patologías actuales y desvalimiento, especialmente para esta población AU

Psychological assessment in Brazil is governed by Normative Instructions and Resolutions that indicate the necessary or impeding personality characteristics for various work, educational and social areas. Postulated by Maldavsky, Intrasomatic Libido (LI) is a libidinal phase where current pathologies originate (Pathologies of Helplessness). LI can be detected in the subject's speech and also in tests such as the Z-Test (Burani, 2020 and 2022) and the Desiderative Questionnaire -QD (Sneiderman, 2012) according to new theoretical contributions. Objective: The objective of this article is to present the Intrasomatic Libido detected in Psychological Assessment of the personality in the analysis of the speech and updated projective test protocols, through the application of the Z-Test and Desiderative Questionnaire and the evaluated speech.Material and Methods: We analyzed 211 QD and Z-Test protocols, and health data obtained in interviews, from men aged between 30 and 60 years evaluated for use of weapons. This research was approved by Plataforma Brasil, CAAE: 42474920.4.0000.0123 and is part of the author's thesis. Results: Analysis of the protocols indicated which erogeneities were predominant in the responses: LI appeared in 15% of the Z-test responses and in 13% of the QD responses. We linked this frequency to the health data of those evaluated through their speech, indicating the presence of hypertension, diabetes, respiratory problems, allergies among other current pathologies of helplessness, and in most cases in addictions and tendency to accidents. Conclusions: The detection of erogeneities in projective test responses allows not only a better assessment of personality characteristics, but also the detection of current helplessness pathologies. The presence of LI in psychological assessment for the use of firearms indicates the need for deeper studies regarding the current pathologies of helplessness, especially for this population AU

The Impact of Rumen-Protected L-Arginine Oral Supplementation on Libido, Semen Quality, Reproductive Organ Biometry, and Serum Biochemical Parameters of Rams.

This study aimed to investigate the effect of oral supplementation of rumen-protected L-arginine on semen quality, testes, and accessory genital glands biometry in rams. Ten apparently healthy and fertile rams were randomly divided into two equal groups; control, and rumen-protected L-arginine (20 mg/Kg body weight for 30 days) treated group. In all rams, ultrasonographic measurements of the testes and the accessory genital glands and blood sampling were performed at day (D)10, D20, and D30 (D0 is the start of supplementation). Semen ejaculates were collected twice/week and semen quantity, and quality was examined. Our results showed that, in the L-arginine treated group, there were significant increase in the ultrasound biometric measurement of right seminal vesicle (RSV) and right Cowper's gland (RCG) at D10, both testes, tail of the epididymis (TE), SV, and CG of both sides at D20, and of both testes, RTE, RSV, RCG, and LSV at D30. Semen quality and quantity parameters were significantly improved in L-arginine treated group. Moreover, testosterone level in the L-arginine treated group was significantly higher than that in the Control group. Serum thyroxine and glutathione peroxidase concentrations were significantly higher in the L-arginine treated group. The present study concluded that oral supplementation with rumen-protected L-arginine is beneficial in improvement of rams' fertility.

Concentrations of Boar Taint Compounds Are Weakly Associated with Sexual Behavior of Young Boars.

Strategies to control boar taint (BT) in meat relies on the reduction of skatole, indole, and androstenone concentration. This might have unfavorable effects on the libido of breeding boars. The association between BT compound concentration in backfat and libido was investigated in 391 commercial breeding boars. Six sexual behavior traits (SBT; sexual arousal, salivation, mounting performance, interest in the dummy sow, penis unsheathing, and overall libido score) were scored during the training of the boars with the dummy sow. Variation in SBT was analyzed by proportional-odds cumulative logistic models. Overall, indole, skatole, and androstenone concentrations were weakly associated with libido. Farm of origin, age at training or body weight, and BT compound levels were poor predictors of boar performance (the area under the ROC curve ranged from 0.60 to 0.69). This indicates that BT compound concentrations were weakly associated with libido, even though the probability of observing good SBT scores increased with high levels of androstenone, intermediate or low levels of skatole, and intermediate to high levels of indole. Hence, practices aiming at reducing androstenone, and controlling the concentrations of skatole and indole to intermediate levels are not expected to impair the libido of young boars.

Female Reproductive Health Disturbance Experienced During the COVID-19 Pandemic Correlates With Mental Health Disturbance and Sleep Quality.

The COVID-19 pandemic has adversely affected population mental health. Periods of psychological distress can induce menstrual dysfunction. We previously demonstrated a significant disruption in women's reproductive health during the first 6 months of the pandemic. The present study investigates longer-term reproductive and mental health disturbances. A cross-sectional online survey was completed by 1335 women of reproductive age in April 2021. It included validated standardized measures of depression (PHQ-9), anxiety (GAD-7) and sleep quality (PSQI). 581 (56%) of women reported an overall change in their menstrual cycle since the beginning of the pandemic. There was no change in median cycle length [28 days (28-30)] or days of menses [5 (4-5)], but there was a wider variability in minimum (p<0.0001) and maximum (p<0.0001) cycle length. There was a significant increase in heavy menstrual bleeding, painful periods and missed periods compared to pre-pandemic (all p<0.0001). 64% of women reported worsening pre-menstrual symptoms. Rates of severe depression, anxiety and poor sleep were more than double those from large scale representative community samples. Poor sleep quality was an independent predictor of overall change in menstrual cycle (OR=1.11, 95%CI 1.05-1.18), and missed periods (OR=1.11, 95%CI 1.03-1.19) during the pandemic. Increased anxiety was independently associated with a change from non-painful to painful periods (OR=1.06, 95%CI 1.01-1.11) and worsening of pre-menstrual symptoms (OR=1.06, 95%CI 1.01-1.07) during the pandemic. The COVID-19 pandemic continues to bear a significant impact on female reproductive health. Increased levels of psychological distress and poor sleep are associated with menstrual cycle disruption.
