RESUMO
PURPOSE: To correlate the sexual desire levels with sexual hormone binding globulin and free androgen index in women taking different types of hormonal contraceptives (HCs) containing ethinylestradiol (EE), oestradiol valerate (E2V), 17ß-oestradiol (E2), or estetrol (E4), combined or in phasic formulation with different progestogens having antiandrogenic properties. METHODS: Three hundred and sixty-seven women (age range 18-46) participated in the study. SHBG and total testosterone (TT) were measured, and the Free Androgen Index (FAI) was calculated. The Female Sexual Function Index (FSFI) and the Female Sexual Distress Scale (FSDS) questionnaires were used to assess sexual function and distress, respectively. RESULTS: The highest SHBG values and the lowest FAIs were obtained of women on HCs containing EE than those of women on HCs containing E2V/17ß E2 or E4 (p < 0.001). Desire scores and FSFI total scores were lower in women on HCs with EE than in those using HCs containing E2V, 17ß E2, or E4 (p ≤ 0.001). The women who were on HCs containing EE reported FSDS levels higher than those containing all the other types of oestrogen. Finally, sexual desire and FSFI total scores had a negative correlation with the SHBG values and a positive correlation with FAI percentage (p ≤ 0.0001). CONCLUSIONS: A minority of women using HCs with EE might experience a decreased sexual desire. This was not observed in women on HCs containing E2V, 17 E2, or E4. To avoid HC discontinuation, due to sexual desire reduction, HCs having minor antiandrogenic effects could be taken into consideration.

INTRODUCTION: Sexual side effects of combined oral contraceptives (COCs) have not been fully understood, but increasing evidence prompts broader risk/benefit evaluation and merits inclusion in counseling on contraceptive options. OBJECTIVES: The study sought to explore the impact of combined estrogens-progestin oral contraceptives on components of female sexuality, including sexual desire, anatomic genitourinary changes, lubrication, orgasm, provoked vestibulodynia, well-being, body image, partner preference, and relationship stability. METHODS: A literature review was performed between April 2023 and January 2024 exploring the association between combined oral contraceptive pills and sexual health. RESULTS: Although COCs decrease free testosterone, it is unclear if COCs affect sexual function, including desire. Antiandrogenic COCs do seem to have a negative effect on sexual arousal, lubrication, and orgasm. Provoked vestibulodynia may be related to early onset of COC use, low-estrogen pills, and antiandrogenic progestins. Emotional and sexual side effects are strong predictors of COC discontinuation. Longitudinal data indicate that using COCs when meeting and selecting a partner has implications on sexual satisfaction and relationship length. Analysis of data is complicated by various doses and forms of estrogen and progestin in COCs, which have changed over time. CONCLUSION: Lack of randomized placebo-controlled studies and heterogenicity in study design hampers generalized statements about the effects of COCs on sexual function. Despite these challenges, consideration of sexual dysfunction when presenting and prescribing hormonal contraception is essential for informed consent, shared decision making, and ensuring reliable contraceptive choices.

PURPOSE: Because of the negative impact of cancer treatment on female sexual function, effective treatments are warranted. The purpose of this multisite study was to evaluate the ability of two dose levels of extended-release bupropion, a dopaminergic agent, to improve sexual desire more than placebo at 9 weeks, measured by the desire subscale of the Female Sexual Function Index (FSFI), and to evaluate associated toxicities. METHODS: Postmenopausal women diagnosed with breast or gynecologic cancer and low baseline FSFI desire scores (< 3.3), who had completed definitive cancer therapy, were eligible. Women were randomly assigned to receive 150 mg or 300 mg once daily of extended-release bupropion or a matching placebo. t-tests were performed on the FSFI desire subscale to evaluate whether there was a significantly greater change from baseline to 9 weeks between placebo and each bupropion arm as the primary end point. Sixty-two patients per arm provided 80% power using a one-sided t-test. RESULTS: Two hundred thirty women were randomly assigned from 72 institutions through the NRG Oncology NCORP network. At 9 weeks, there were no statistically significant differences in change of the desire subscale scores between groups; participants in all three arms reported improvement. The mean changes for each arm were placebo 0.62 (standard deviation [SD] = 1.18), 150-mg once daily bupropion 0.64 (SD = 0.95), and 300-mg once daily bupropion 0.60 (SD = 0.89). Total and subscale scores on the FSFI were low throughout the study, indicating dysfunction in all groups. CONCLUSION: Bupropion was not more effective than placebo in improving the desire subscale of the FSFI. Subscale and total scores of the FSFI demonstrated dysfunction throughout the 9 weeks of the study. More research is needed to support sexual function in female cancer survivors.

BACKGROUND: There has been recent interest in the use of botulinum neurotoxin (BoNT) in the field of Andrology, whereby it has been investigated in the treatment of penile retraction and premature ejaculation. OBJECTIVES: To evaluate the safety and efficacy of intracavernosal BoNT-A injection in the treatment of patients with erectile dysfunction (ED) refractory to oral phosphodiesterase inhibitors (PDE5Is). PATIENTS AND METHODS: A double-blind randomized placebo-controlled prospective comparative study conducted at one center and involved 70 patients with ED refractory to PDE5Is. At baseline, the following data were collected: erection hardness score (EHS), peak systolic velocity (PSV), end diastolic velocity (EDV), sexual health inventory for men (SHIM), and the sexual encounter profile 2&3 (SEP-2&3) questionnaires. Treatment group (n = 35) received a single ICI of 100 units of BoNT-A in 2 ml of saline and control group (n = 35) received a single ICI of 2 ml of saline. EHS, PSV, and EDV were assessed at 2 weeks post treatment. SHIM, SEP-2, SEP-3, and global assessment questionnaire (GAQ-Q1&Q2) were completed at 2-, 6-, and 12-weeks post treatment. RESULTS: Two weeks post treatment, the treatment group showed a statistically significant improvement in the mean EHS, PSV, EDV, and GAQ-Q1 positive responders (p < 0.001) compared to the control group. At 6- and 12-weeks post treatment, the treatment group showed a statistically significant improvement in the SHIM scores, SEP-2, and GAQ-Q1&Q2 positive responders compared to the control group. At 6 weeks, where there was a 5-point improvement in the mean SHIM score of the treatment group (10±5.9 from 5.4±1.7 at baseline) versus no improvement in the placebo group, 18 patients in the treatment group (53%) were able to have an erection hard enough for vaginal penetration versus only one patient in the control group. CONCLUSION: BoNT-A is safe and effective as a potential treatment for ED refractory to PDE5I therapy.

BACKGROUND: Survivors of germ-cell tumors (GCT) may suffer from long-term adverse consequences. Our study was conducted to assess a long-term sexual functioning in GCT survivors. METHODS: GCT survivors (N = 170) from the National Cancer Institute in Slovakia completed a Sexual Function Questionnaire that was modified from PROMIS Sexual Function and Satisfaction Questionnaire 9-year median follow up (range 5-32) as a primary exploratory aim. Study groups consisted of 17 survivors (10%) who had active surveillance (AS, controls), and 153 (90%) survivors who received treatment beyond orchiectomy (Tx), including cisplatin-based chemotherapy (CT, N = 132; 78%), radiotherapy to the retroperitoneal lymph nodes (RT, N = 12; 7%) or both (CTRT, N = 9; 5%). RESULTS: In univariate analysis, treatment of any type resulted in difficulty to maintain erection during sexual intercourse compared to patients treated with AS (P = 0.04). Survivors who received CTRT had lower ability to achieve orgasm during sexual activities (P = 0.04) and they reported disappointment with their overall quality of sex life (P = 0.002). The number of attempts to initiate sexual intercourse did not differ. Sexual relationships caused none or mild anxiety and the desire to be sexually active was higher after CTRT (P = 0.05). Multivariable analysis confirmed that orgasmic dysfunction after ≥400 mg/m2 of cisplatin and issues in maintaining erection after Tx were independent of retroperitoneal lymph-node dissection (P = 0.03 and P = 0.04, respectively). Survivors were disappointed with the quality of sex life and had stronger desire to be sexually active independent of age, (P = 0.01 and P = 0.05, respectively). CONCLUSIONS: This study identified an impairment in sexual function may represent an issue for long-term GCT survivors. Treatment with chemotherapy plus radiotherapy were associated with disappointment and stronger sexual desire, while a higher cumulative dose of cisplatin may be responsible for orgasmic dysfunction.

BACKGROUND: Information regarding the possible influence of immunosuppressive drugs on male sexual function and reproductive outcomes is scarce. Men diagnosed with immune-mediated diseases and a wish to become a father represent an important neglected population since they lack vital information to make balanced decisions about their treatment. OBJECTIVE AND RATIONALE: The aim of this research was to systematically review the literature for the influence of paternal immunosuppressive drug use on many aspects of male sexual health, such as sexual function, fertility, pregnancy outcomes and offspring health outcomes. SEARCH METHODS: A systematic literature search was performed in the bibliographic databases: Embase (via Elsevier embase.com), MEDLINE ALL via Ovid, Cochrane Central Register of Trials (via Wiley) and Web of Science Core Collection. Additionally, Google Scholar and the Clinical trial registries of Europe and the USA were searched. The databases were searched from inception until 31 August 2019. The searches combined keywords regarding male sexual function and fertility, pregnancy outcomes and offspring health with a list of immunosuppressive drugs. Studies were included if they were published in English and if they included original data on male human exposure to immunosuppressive drugs. A meta-analysis was not possible to perform due to the heterogeneity of the data. OUTCOMES: A total of 5867 references were identified, amongst which we identified 161 articles fulfilling the eligibility criteria. Amongst these articles, 50 included pregnancy and offspring outcomes and 130 included sexual health outcomes. Except for large Scandinavian cohorts, most of the identified articles included a small number of participants. While a clear negative effect on sperm quality was evident for sulfasalazine and cyclophosphamide, a dubious effect was identified for colchicine, methotrexate and sirolimus. In three articles, exposure to tumour necrosis factor-α inhibitors in patients diagnosed with ankylosing spondylitis resulted in improved sperm quality. The information regarding pregnancy and offspring outcomes was scant but no large negative effect associated with paternal immunosuppressive drug exposure was reported. WIDER IMPLICATIONS: Evidence regarding the safety of immunosuppressive drugs in men with a wish to become a father is inconclusive. The lack of standardisation on how to evaluate and report male sexual function, fertility and reproduction as study outcomes in men exposed to immunosuppressive drugs is an important contributor to this result. Future research on this topic is needed and should be preferably done using standardised methods.

PURPOSE: To systematically review the impact of smoking habits on cardiovascular (CV) as well as on male sexual and reproductive function and to provide updated evidence on the role of electronic cigarettes (e-Cig) on the same topics. METHODS: A comprehensive Medline, Embase, and Cochrane search was performed including the following words: smoking, CV system, CV risk, erectile dysfunction (ED), and male fertility. Publications from January 1, 1969 up to February 29, 2020 were included. RESULTS: Smoking has a tremendous negative impact on CV mortality and morbidity. Current smoking behavior is also negatively associated with erectile dysfunction (ED) and impaired sperm parameters. E-Cig can release significantly lower concentrations of harmful substances when compared to regular combustible cigarettes. Whether or not the latter can result in positive CV, sexual, and fertility outcomes is still under study. Preliminary studies showed that exposure to e-Cig leads to lower vascular damage when compared to the traditional cigarette use. However, data on the long-term effects of e-Cig are lacking. Similarly, preliminary data, obtained in animal models, have suggested a milder effect of e-Cig on erectile function and sperm parameters. CONCLUSION: Available evidence showed that e-Cig are much less dangerous when compared to the traditional tobacco use. However, it should be recognized that the risk related to e-Cig is still higher when compared to that observed in non-smoking patients. Hence, e-Cig should be considered as a potential tool, in the logic of harm reduction, to reduce the CV, sexual and fertility risk in patients refractory to the fundamental, healthy choice to definitively quit smoking.

INTRODUCTION: Combined radiotherapy and hormonal treatment are recommended for intermediate- and high-risk prostate cancer (CaP). This study compared the long-term effects on health-related quality of life (HRQoL) of intermediate- and high-risk CaP patients managed with radiation therapy (RT) with vs. without hormone therapy (HT). METHODS: Patients with intermediate- and high-risk CaP enrolled in the Center for Prostate Disease Research diagnosed from 2007 to 2017 were included. EPIC and SF-36 questionnaires were completed and HRQoL scores were compared for patients receiving RT vs. RTâ¯+â¯HT at baseline (pretreatment), 6, 12, 24, 36, 48, and 60 months after CaP diagnosis. Longitudinal patterns of change in HRQoL were modeled using linear regression models, adjusting for baseline HRQoL, age at CaP diagnosis, race, comorbidities, National Comprehensive Cancer Network (NCCN) risk stratum, time to treatment, and follow-up time. RESULTS: Of 164 patients, 93 (56.7%) received RT alone and 71 (43.3%) received RTâ¯+â¯HT. Both groups reported comparable baseline HRQoL. Patients receiving RT+HT were more likely to be NCCN high risk as compared to those receiving only RT. The RTâ¯+â¯HT patients experienced worse sexual function, hormonal function, and hormonal bother than those who only received RT; however, HRQoL recovered over time for the RTâ¯+â¯HT group. No significant differences were observed between groups in urinary and bowel domains or SF-36 mental and physical scores. CONCLUSION: Combined RTâ¯+â¯HT treatment was associated with temporary lower scores in sexual and hormonal HRQoL compared with RT only. Intermediate- and high-risk CaP patients should be counseled about the possible declines in HRQoL associated with HT.

Importance: Many young men have poor semen quality, and the causes are often unknown. Supplement intake of ω-3 polyunsaturated fatty acid has been found to improve semen quality among men with infertility, but the association with semen quality among healthy men is unknown. Objective: To determine if intake of ω-3 fatty acid supplements is associated with testicular function as measured by semen quality and reproductive hormone levels among healthy men. Design, Setting, and Participants: This cross-sectional study included young Danish men from the general population recruited between January 1, 2012, and December 31, 2017, at compulsory examinations to determine their fitness for military service. Young unselected men were approached after the examination and invited to participate in a study of reproductive function, regardless of their fitness for military service. Data analysis was conducted from September 1, 2018, to June 30, 2019. Exposures: Intake of supplements, including fish oil, during the past 3 months. Main Outcomes and Measures: Semen quality, measured as volume, concentration, total sperm count, percentage of morphologically normal spermatozoa, and motility, and serum reproductive hormone levels, measured as follicle-stimulating hormone, luteinizing hormone, testosterone, free testosterone, and inhibin B levels. Results: Among 1679 young Danish men (median [interquartile range] age, 18.9 [18.7-19.4] years) recruited to participate, 98 men (5.8%) reported use of fish oil supplements during the past 3 months, of whom 53 (54.1%) reported intake on 60 or more days. After adjustment and compared with men with no supplement intake, men with fish oil supplement intake on fewer than 60 days had semen volume that was 0.38 (95% CI, -0.03 to 0.80) mL higher, and men with fish oil supplement intake on 60 or more days had semen volume that was 0.64 (95% CI, 0.15 to 1.12) mL higher (P for trend < .001). Similarly, testicular size in men with supplement intake on fewer than 60 days was 0.8 (95% CI, -0.2 to 1.9) mL larger and in men with fish oil supplement intake on 60 or more days was 1.5 (95% CI, 0.2 to 2.8) mL larger compared with men with no supplement intake (P for trend = .007). After adjustment, men with fish oil supplement intake had a 20% (95% CI, 9%-31%) lower follicle-stimulating hormone level and 16% (95% CI, 8%-24%) lower luteinizing hormone level compared with men with no supplement intake. There were no associations of intake of other supplements with measures of testicular function. Conclusions and Relevance: These findings suggest that intake of fish oil supplements was associated with better testicular function, which is less likely to be due to confounding by indication, as no associations of intake of other supplements with testicular function were found. This cross-sectional study did not examine the actual content of ω-3 fatty acids in the supplements; therefore, these findings need confirmation in well-designed randomized clinical trials among unselected men.

It has long been known that the estrogen, 17ß-estradiol (17ß-E), plays a central role for female reproductive physiology and behavior. Numerous studies have established the neurochemical and molecular basis of estrogenic induction of female sexual behavior, i.e., lordosis, in animal models. In addition, 17ß-E also regulates male-type sexual and aggressive behavior. In males, testosterone secreted from the testes is irreversibly aromatized to 17ß-E in the brain. We discuss the contribution of two nuclear receptor isoforms, estrogen receptor (ER)α and ERß to the estrogenic regulation of sexually dimorphic brain formation and sex-typical expression of these social behaviors. Furthermore, 17ß-E is a key player for social behaviors such as social investigation, preference, recognition and memory as well as anxiety-related behaviors in social contexts. Recent studies also demonstrated that not only nuclear receptor-mediated genomic signaling but also membrane receptor-mediated non-genomic actions of 17ß-E may underlie the regulation of these behaviors. Finally, we will discuss how rapidly developing research tools and ideas allow us to investigate estrogenic action by emphasizing behavioral neural networks.

OBJECTIVES: Erectile dysfunction (ED) is characterised as the inability to achieve or maintain an erection to complete sexual intercourse. ED may be considered as an early complication of diabetes mellitus (DM). The aim of this study was to assess the effect of registered food supplement, natural polyphenolic extract from the French maritime pine bark, Pycnogenol (PYC) on erectile function and lipid profile in ED patients. METHODS: 53 patients with ED were divided into two groups (32 with DM, 21 non-DM) in randomised, blinded and placebo-controlled study. During 3-month intervention with PYC or placebo and one month after the end of the intervention patients were investigated for ED with validated questionnaire International Index of Erectile Function-5 (IIEF-5); lipid profile, glycaemia was analysed in each group. RESULTS: In a randomised, blinded and placebo-controlled study, we found that natural polyphenolic extract, Pycnogenol improved erectile function in DM group by 45 % compared to the NDM group, where the improvement was also significant, but only by 22 %. Total cholesterol, LDL-cholesterol and glucose level was lowered by PYC in patients with DM. Glucose level was not affected by PYC in non-DM. Placebo showed no effect on monitored parameters in both groups. CONCLUSION: Administration of Pycnogenol leads in improvement of erectile function in patients with ED and diabetes (DM group) by 45 %, in NDM group by 22 %, in lowering of total-, LDL-cholesterol by 20 % and 21 % and glycaemia by 22 % in DM (Tab. 2, Fig. 2, Ref. 19).

INTRODUCTION: Prior medication treatment for hypoactive sexual desire disorder (HSDD) in women has left about half the subjects without benefit. Lorexys (LOR), a proprietary combination of the stimulating/excitatory dopamine-norepinephrine reuptake inhibitor bupropion (BUP) and the sedating/inhibitory serotonergic agonist-antagonist trazodone (TRZ), was developed as a multifunctional solution for this problem. AIM: Test efficacy, safety, and tolerability of LOR in a range of doses in a combined phase IB/IIA study in premenopausal outpatients with HSDD. METHODS: Otherwise healthy premenopausal women from 25-50 years of age with HSDD were tested in an open-label, active-control, one-way crossover study, with three 4-week treatments of extended-release TRZ and/or sustained-release BUP. Evaluations were made before and after each treatment. A washout of at least a week followed each treatment. The order of treatments was a standard dose of BUP; a subtherapeutic dose of BUP and TRZ (LOR-low); and a threshold-therapeutic dose of BUP and TRZ (LOR-mod). A midpoint interim analysis was planned to consider adapting doses for efficacy or safety. MAIN OUTCOME MEASURE: The primary efficacy measure was the Female Sexual Function Index, Desire domain; the main secondary efficacy measures included the Female Sexual Distress Scale-Revised 13th item, on bother about low desire, and a Patient's Global Impression of Change. The main outcome comparison was the proportions of responders. Safety measures were elicited adverse events, Epworth Sleepiness Scale, Columbia Suicide Severity Rating Scale 6-item SCREEN version, vital signs, electrocardiograms, and standard laboratory tests. RESULTS: Interim analysis did not require altering doses. Most evaluable subjects responded to LOR-mod (at the standard thresholds for response based on minimum clinically relevant difference from baseline, 79% on Female Sexual Function Index, Desire domain, 87% on Female Sexual Distress Scale-Revised Item 13, and 79% on Patient's Global Impression of Change; each P < .05 vs BUP). As expected, close to half responded to BUP (38%, 45%, and 52%, respectively). Response to LOR-low was intermediate (not significant vs BUP). Sensitivity analyses to compensate for carryover effects supported the efficacy of LOR-mod. Elicited adverse events showed the expected profile of TRZ, but led to no sedative-type dropouts or worsening on the Epworth Sleepiness Scale. CLINICAL IMPLICATIONS: The open-label 1-way crossover design of this phase IB/IIA study limits conclusions, but the consistency of responder analyses showing superiority of LOR-mod dose over control, and the lack of central depressant dropouts, favor further development in double-blind placebo-control trials. STRENGTH & LIMITATIONS: Strengths include large margins of efficacy over control agent, rapid onset of action, and rigorous safety assessment. Limitations are open-label, cross-over design/lack of placebo control and 1-month duration of exposure. CONCLUSION: Moderate-dose LOR was generally well-tolerated and was significantly more effective than BUP (active control). The results seem highly favorable compared to previously tested agents.

Studies assessing the efficacy of intralesional verapamil injection in the treatment of Peyronie's disease have yielded mixed results. The purpose of this meta-analysis is to systematise the existing literature on the efficacy of intralesional verapamil injection when used in the treatment of Peyronie's disease. The treatment outcomes of seven different study groups identified by computerised literature search were compared with natural history outcomes and data from control groups of three studies involving placebo saline injection. An exploratory meta-analysis was performed on the data due to differing patient populations, treatment protocols, and inconsistent selection and reporting of outcomes. Intralesional verapamil injection significantly improved sexual function (p < .0005) and penile curvature (p < .005) in individuals with Peyronie's disease. Decreases in pain may be significant after therapy but are questionable. The effect of verapamil on plaque size remains less impressive (p > .05). Intralesional verapamil injection has promise to positively impact a number of clinical outcomes of Peyronie's disease; however, a large, multicentre, randomised, controlled study with reliable protocols is needed to confirm the efficacy of treatment.

In comparison to other antidepressant drugs, erectile dysfunction (ED) is more pronounced in paroxetine use. On the other hand, orange (Citrus sinensis) peels commonly consumed in various forms are used in folkloric medicine for ED management. Thus, this study evaluated the effect of orange peels infusion on sexual behaviour, nitric oxide (NO) level and some enzymes (arginase, phosphodiesterase-5 [PDE-5], acetylcholinesterase [AChE] and adenosine deaminase [ADA]) in paroxetine-treated rats. Erectile dysfunction was induced with paroxetine (10 mg/kg body weight). The animals were grouped into five (n = 6): normal rats; paroxetine-induced rats; paroxetine-induced rats treated with sildenafil citrate (5 mg/kg); paroxetine-induced rats treated with orange peels infusion (50 mg/kg); Paroxetine induced rats treated with orange peel infusions (100 mg/kg). The results revealed a significant decrease in sexual behaviour, NO level and the activities of antioxidant enzymes, while there was a significant increase in arginase, PDE-5, AChE and ADA activities in paroxetine-induced rats. However, orange peel infusions ameliorated erectile dysfunction in paroxetine-treated rats. This study showed some possible biochemical basis underlying the use of orange peels infusion in erectile dysfunction management.

Sexually Transmitted Diseases (STDs) refer to a variety of clinical syndromes and infections caused by pathogens that can be acquired and transmitted through sexual activity. Among STDs widely reported in the literature, viral sexual diseases have been increasing in a number of cases globally. This emphasizes the need for prevention and treatment. Among the methods widely used in drug planning are Computer-Aided Drug Design (CADD) studies and molecular docking which have the objective of investigating molecular interactions between two molecules to better understand the three -dimensional structural characteristics of the compounds. This review will discuss molecular docking studies applied to viral STDs, such as Ebola virus, Herpes virus and HIV, and reveal promising new drug candidates with high levels of specificity to their respective targets.

ETHNOPHARMACOLOGICAL RELEVANCE: Piper auritum Kunth is employed as an aphrodisiac in the traditional medicine, but corroborative evidence for such effect is scarce. AIM OF THE STUDY: The pro-sexual effect of an aqueous extract of P. auritum and its possible mechanisms were analyzed in two paradigms of male sexual function. MATERIAL AND METHODS: Effects of an aqueous extract of P. auritum (PA, single administration) were investigated in the fictive ejaculation, and copulatory behavior paradigms in sexually sluggish male rats. WAY 100635 (antagonist of 5-HT1A receptors), atosiban (antagonist of oxytocinergic receptors), L-NAME (inhibitor of the nitric oxide synthase) and baclofen (antagonist of GABAB receptors) were used as pre-treatments in order to investigate the role of different neurotransmitter systems in PA actions. Chemical profile of PA was determined by Gases Chromatography and Ultra Performance Chromatography-Electrospray Ionization-Masses Spectrometry (UPLC-ESI-MS). RESULTS: In males with retarded ejaculation, PA stimulated ejaculatory behavior and recovered electromyographic activity of pelvic musculature participating in seminal emission and ejaculation. All pre-treatments blocked stimulating effects of PA on the fictive ejaculation; additionally WAY 100635 interfered with PA actions on ejaculatory behavior. Safrol, apigenin dimethylether, myristicin, vaccihein A, sakuranin and sakuranetin flavonoids, were main constituents of PA, with possible participation in its pro-sexual effects. CONCLUSIONS: Pro-sexual effects of P. auritum elicited at level of ejaculation were mediated by several neurotransmitter systems, among which serotonin and its 5-HT1A receptors play an important role. Present findings support P. auritum reputation as an aphrodisiac, with potential use in delayed ejaculation disorder.

OBJECTIVES: Associations between chronic pain, opioid use, and sexual problems are acknowledged, but population-based investigations are sparse. Our study aimed at investigating the associations between chronic noncancer pain (CNCP), opioid use, lack of/low sexual desire, and dissatisfaction with sexual life. SUBJECTS: In 2013, 11,517 randomly selected individuals of the Danish population (18-74 years old without cancer) completed a self-administered questionnaire. METHODS: We classified CNCP: pain lasting six months or longer, short-term opioid use: one or more prescriptions the previous year, long-term opioid use: one or more prescriptions per month for six months the previous year. Sexual problems were assessed by four closed-ended questions. Data on dispensed opioids were retrieved from the Danish National Prescription Registry. Multiple logistic regression analysis was used to examine associations between CNCP, opioid use, and lack of/low sexual desire, and dissatisfaction in sexual life, presented as odds ratios (95% confidence intervals [CIs]). RESULTS: Compared with individuals without CNCP, individuals with CNCP in the long-term and short-term opioid use group and in the nonopioid use group were more likely to report a lack of/low sexual desire (OR = 2.64, 95% CI = 1.80-3.88; OR = 1.82, 95% CI = 1.39-2.38; OR = 1.46, 95% CI = 1.28-1.67, respectively) and dissatisfaction with sex life (OR = 1.69, 95% CI = 1.07-2.67; OR = 1.35, 95% CI = 1.00-1.82; OR = 1.38, 95% CI = 1.22-1.58, respectively). Compared with CNCP patients not using opioids, long-term opioid users with CNCP had statistically significant higher odds of reporting a lack of/low sexual desire (OR = 1.81, 95% CI = 1.23-2.68). CONCLUSIONS: Long-term opioid therapy for CNCP requires special attention due to its potential in suppressing sexual desire.

CONTEXT: In 46,XY disorders of sexual development (DSD) patients, several factors may affect psychosexual development, leading to gender identity discrepancy and gender change later in life. Prenatal sexual steroid exposure and external genital virilization are considered to influence human psychosexual development, but their roles not completely understood yet. DESIGN: A total of 144 individuals (18 to 60 years of age) with a clinical/molecular diagnosis of 46,XY DSD from a single tertiary center were enrolled. Psychosexual outcomes (gender role, gender identity, and sexual orientation) were assessed using questionnaires and psychological test. The Sinnecker score was used for genital virilization measurement. Prenatal androgen exposure was estimated according to 46,XY DSD etiology. RESULTS: We found a positive association between prenatal androgen exposure and male psychosexual outcomes. Alternatively, prenatal estrogen exposure, age of gonadectomy, and the degree of external genital virilization did not influence any psychosexual outcome. There were 19% (n = 27) with gender change, which was associated with prenatal androgen exposure (P < 0.001) but not with the external genital virilization. The median age of gender change was 15 years, but most of the patients reported the desire for gender change earlier. CONCLUSIONS: Prenatal androgen exposure influenced psychosexual development in 46,XY DSD favoring male psychosexuality in all psychosexual outcomes, whereas the degree of external genital virilization did not influence these outcomes. The organizational effect of sexual steroids on psychosexuality at puberty appears to be weak in comparison with the prenatal effects. Prenatal androgen exposure also influenced female-to-male gender change frequency. All 46,XY DSD conditions with prenatal androgen exposure must be followed for gender issues in their management.

BACKGROUND: Resting brain connectivity is a crucial component of human behavior demonstrated by disruptions in psychosexual and emotional disorders. Kisspeptin, a recently identified critical reproductive hormone, can alter activity in certain brain structures but its effects on resting brain connectivity and networks in humans remain elusive. METHODS: We determined the effects of kisspeptin on resting brain connectivity (using functional neuroimaging) and behavior (using psychometric analyses) in healthy men, in a randomized double-blinded 2-way placebo-controlled study. RESULTS: Kisspeptin's modulation of the default mode network (DMN) correlated with increased limbic activity in response to sexual stimuli (globus pallidus r = 0.500, P = 0.005; cingulate r = 0.475, P = 0.009). Furthermore, kisspeptin's DMN modulation was greater in men with less reward drive (r = -0.489, P = 0.008) and predicted reduced sexual aversion (r = -0.499, P = 0.006), providing key functional significance. Kisspeptin also enhanced key mood connections including between the amygdala-cingulate, hippocampus-cingulate, and hippocampus-globus pallidus (all P < 0.05). Consistent with this, kisspeptin's enhancement of hippocampus-globus pallidus connectivity predicted increased responses to negative stimuli in limbic structures (including the thalamus and cingulate [all P < 0.01]). CONCLUSION: Taken together, our data demonstrate a previously unknown role for kisspeptin in the modulation of functional brain connectivity and networks, integrating these with reproductive hormones and behaviors. Our findings that kisspeptin modulates resting brain connectivity to enhance sexual and emotional processing and decrease sexual aversion, provide foundation for kisspeptin-based therapies for associated disorders of body and mind.
