Androgen-based therapies in women.

Androgens play a key biological role in libido and sexual arousal in women, and knowledge about their complex role in other systems remains ambiguous and incomplete. This narrative review examines the role of endogenous androgens in women's health throughout the life span before focusing on evidence surrounding the use of androgen-based therapies to treat postmenopausal women. The role of testosterone as a therapeutic agent in women continues to attract controversy as approved preparations are rare, and use of off-label and compounded formulations is widespread. Despite this androgen therapy has been used for decades in oral, injectable, and transdermal formulations. Responses to androgen therapy have been demonstrated to improve aspects of female sexual dysfunction, notably hypoactive sexual desire disorder, in a dose related manner. Substantial research has also been conducted into the role of androgens in treating aspects of the genitourinary syndrome of menopause (GSM). Evidence for benefits beyond these is mixed and more research is required regarding long-term safety. However, It remains biologically plausible that androgens will be effective in treating hypoestrogenic symptoms related to menopause, either through direct physiological effects or following aromatization to estradiol throughout the body.

Ovarian hormones in relation to naturally cycling women's conception risk: Empirical evidence and implications for behavioral endocrinology.

A substantial body of literature has examined how women's psychology and behavior vary as a function of conception risk across the ovarian cycle. These effects are widely believed to be outcomes of hormonal regulation, in particular effects of estrogens (E) and progesterone (P). Increasingly, researchers have sought to test predictions about how psychological processes or behavior vary as a function of conception risk by examining associations with estrogen (e.g., estradiol) and progesterone levels. Yet issues regarding how best to assess these associations arise. Should hormone levels be log-transformed? Do hormone ratios best capture their joint effects? How important are hormone interactions? How should outliers be treated? Across two large datasets, we examined hormonal predictors of conception risk, estimated from day of a luteinizing hormone (LH) surge. Log-transformed E and P levels predicted conception risk better than raw E and P levels did. The raw E/P ratio was a relatively poor predictor, whereas the log-transformed ratio (ln[E/P]) was a relatively good predictor. E × P interactions were detected but weak. Outliers were frequent, especially in distributions of raw hormone levels. Hormone measures predicted two psychological outcomes in these datasets-sexual desire and preferences for strength and muscularity-in parallel to how strongly they predicted conception risk. These results give rise to several recommendations regarding treatment of hormone measures and their use in analyses.

Glutamine restores testicular glutathione-dependent antioxidant defense and upregulates NO/cGMP signaling in sleep deprivation-induced reproductive dysfunction in rats.

Oxidative stress has been linked with sleep deprivation (SD)-induced pathological conditions and reproductive dysfunction. On the other hand, glutamine has been established to have antioxidant property. However, the impact of SD, with or without glutamine, on male reproductive function is yet to be elucidated. Thus, this study was designed to investigate the role of SD, with or without glutamine, on male reproductive function and possible associated mechanisms. Ten-week old male Wistar rats weighing 175.6 g± 0.42 were randomly assigned into vehicle that received per os (p.o.) distilled water, glutamine (1 g/kg; po), SD, and SD + glutamine that received treatments as glutamine and SD. Treatment/exposure lasted for 72 h. The results showed that SD led to reduced body weight, seminiferous luminal and epididymal sperm density, low sperm quality, increased testicular and epididymal malondialdehyde, uric acid, DNA fragmentation, and testicular injury markers. In addition, SD caused a reduction in reduced glutathione level and activities of superoxide dismutase, catalase, glucose-6-phosphate dehydrogenase, glutathione peroxidase, and glutathione-S-transferase. Also, SD increased tumor necrotic factor-α, interleukin-1ß, and nuclear factor-kappa B levels. Furthermore SD led to impaired libido and erectile dysfunction, and suppression of circulatory nitric oxide, gonadotropins and testosterone, and penile cGMP. However, glutamine attenuated the effects induced by SD. Taken together, the findings of this study demonstrate that SD induces reproductive dysfunction via glutathione-dependent defense depletion and down-regulation of NO/cGMP signaling, which was abolished by glutamine supplementation.

The impact of regular sperm donation on bulls' seminal plasma hormonal profile and phantom response.

The aim of this study was to analyze the relationship between the concentration of hormones in the seminal plasma, the bull maintenance system in the insemination station, and the regularity of sperm donation and the response to the phantom (libido level). An additional goal was to determine whether there is a relationship between the hormonal profile in the blood, the sperm plasma, the oxidative and antioxidant profile in the blood of bulls and the biometry of their testicles and scrotum, as well as the quality of their sperm in both different seasons and intensities of reproductive use. For the study, 220 healthy and sexually mature Polish Holstein-Friesian bulls were used. They all had normal libido and were fed equally. The animals were grouped according to the scheme: young (16-20 month/n = 60) and old (26-30 month/n = 60) including: individually housed (n = 30) and group housed (n = 30) young, old individually housed (n = 30) and group housed (n = 30) (n total animals = 120); young animals donating semen once a week (every Thursday) (n = 25) and sporadically (once every two months on a random day of the week) (n = 25), old animals donating semen once a week (every Thursday) (n = 25 ) and sporadic donors (once every two months on a random day of the week) (n = 25) (n total animals = 100). When analyzing the results of this study, it should be stated that regular use has a positive effect on the secretion of sex hormones in bulls. Higher levels of testosterone and lower levels of estradiol and prostaglandins resulted in higher sexual performance, expressed by a stronger response to the phantom. The differences in favor of regular use were independent of the bull's age. The results of our research illustrate that the quality of semen and its freezing potential may depend on the season and frequency of its collection, as well as on the age of the males.

Lifestyle modifications alone or combined with hormonal contraceptives improve sexual dysfunction in women with polycystic ovary syndrome.

OBJECTIVE: To describe the prevalence of female sexual dysfunction in a well-defined polycystic ovary syndrome (PCOS) population, and to assess the impact of common PCOS treatments on sexual function. DESIGN: Secondary analysis of a randomized controlled trial, oral contraceptive pills and weight loss in PCOS. SETTING: Two academic medical centers. PATIENTS: Women with PCOS (N = 114) defined by the Rotterdam criteria. INTERVENTIONS: Continuous oral contraceptive pill (OCP) or intensive lifestyle modification (Lifestyle) or the combination (Combined) for 16 weeks. MAIN OUTCOME MEASURES: Change in Female Sexual Function Index (FSFI) and Female Sexual Distress Scale-Revised (FSDS-R) scores after 16 weeks. RESULTS: There was no change in total FSFI or FSDS-R score in any treatment group; however, an increase in the FSFI desire domain subscore was observed in the Lifestyle and Combined treatments, indicating improved sexual desire over the 16-week period. Overall, 33 participants (28.9%) met criteria for sexual dysfunction by FSFI criteria (baseline score ≤26.55). Among this group, FSFI score improved after 16 weeks of Lifestyle and Combined treatments. There was no change in prevalence of sexual dysfunction in treatment groups at 16 weeks. Use of OCPs did not alter FSFI scores. CONCLUSION(S): Female sexual dysfunction is highly prevalent among women with PCOS. Our findings suggest that common treatments for PCOS, including intensive lifestyle modification and the combination of intensive lifestyle modification and OCPs, have the potential to improve sexual function in these women; the mechanism for these improvements is likely multifactorial. CLINICAL TRIAL REGISTRATION NUMBER: NCT00704912.

Evaluation of sexual functions in infertile Women with Polycystic Ovary Syndrome.

OBJECTIVE: The relationship between sexual functions and infertility remains controversial and there is a limited number of studies reporting the effects of infertility on sexual functions in women with polycystic ovary syndrome (PCOS). Aims: The present study aims to investigate the effects of infertility on sexual functions and depression levels in women with PCOS. METHODS: A total of 150 participants who were either fertile patients with PCOS, infertile patients with PCOS, or fertile women without PCOS (control) (n = 50) were included for the study. Sociodemographic data were recorded and the Female Sexual Function Index (FSFI) and Beck Depression Inventory (BDI) were used for evaluation of subjects. RESULTS: Body mass index (BMI) was found to be significantly higher in the PCOS plus infertility group (27.9 ± 2.9, P = 0.01) than the other groups. Total BDI score was higher and total FSFI score was significantly lower in the PCOS plus infertility group than in the other groups. The PCOS plus infertility group showed significantly lower FSFI scores than the PCOS group in terms of desire, lubrication, orgasm, satisfaction, and pain. A significant negative correlation was observed between BMI and BDI scores in the PCOS plus infertility group (r:-0.384, P = 0.04). CONCLUSION: Our study results show lower sexual functions in PCOS women with infertility and that infertility negatively affects sexual functions with obesity associated depression.

Sexual Dysfunction in Puerto Rican Women with Inflammatory Bowel Disease.

OBJECTIVE: Inflammatory bowel disease (IBD) negatively impacts quality of life-related issues including intimacy, body image, and sexual activity. Sexual dysfunction in patients with IBD is often unrecognized. In this study, we aimed to describe sexual function in Puerto Rican women with IBD. METHODS: We conducted a cross-sectional study of women with IBD at the University of Puerto Rico Center for IBD. Patients were invited to anonymously complete the validated Spanish version of the Female Sexual Function Index (FSFI) questionnaire. On this 36-point scale, a score of 26.55 or less is defined as sexual dysfunction. Data were analyzed by diagnosis, presence of an ostomy, and age, using descriptive statistics, ANOVA, Student's t test, and logistic regression. RESULTS: One hundred women completed the FSFI questionnaire, with subjects having Crohn's disease (CD) outnumbering those having ulcerative colitis (UC) 2:1. The mean sexual function score was 21.92 (95% CI: 20.08-23.76). No statistical difference was observed in total FSFI scores between subjects with CD and UC (p = 0.084) and those with an ostomy (p = 0.891). Sexual function decreased with age (p = 0.001). The domains of excitation, lubrication, orgasm, and satisfaction were the most negatively affected (p<0.05) by increasing age. Multivariate analysis confirmed the effect of age on excitation, lubrication, orgasm, and pain. CONCLUSION: Our study showed sexual dysfunction to be present in this sample of Puerto Rican Hispanic women with IBD. Physicians treating patients with IBD need to be aware of these findings to explore the concerns of individuals with this disease and develop strategies to address those concerns.

Pubertal timing predicts adult psychosexuality: Evidence from typically developing adults and adults with isolated GnRH deficiency.

Evidence suggests that psychosexuality in humans is modulated by both organizational effects of prenatal and peripubertal sex steroid hormones, and by activational effects of circulating hormones in adulthood. Experimental work in male rodents indicates that sensitivity to androgen-driven organization of sexual motivation decreases across the pubertal window, such that earlier puberty leads to greater sex-typicality. We test this hypothesis in typically developing men (n = 231) and women (n = 648), and in men (n = 72) and women (n = 32) with isolated GnRH deficiency (IGD), in whom the precise timing of peripubertal hormone exposure can be ascertained via the age at which hormone replacement therapy (HRT) was initiated. Psychosexuality was measured with the Sexual Desire Inventory-2 (SDI-2) and Sociosexual Orientation Inventory-Revised (SOI-R). In both sexes, earlier recalled absolute pubertal timing predicted higher psychosexuality in adulthood, although the magnitude of these associations varied with psychosexuality type and group (i.e., typically developing and IGD). Results were robust when controlling for circulating steroid hormones in typically developing participants. Age of initiation of HRT in men with IGD negatively predicted SOI-R. We discuss the clinical implications of our findings for conditions in which pubertal timing is medically altered.

Declines in Sexual Activity and Function Predict Incident Health Problems in Older Adults: Prospective Findings from the English Longitudinal Study of Ageing.

The objective of this study was to investigate cross-sectional and longitudinal associations between declines in sexual activity and function and health outcomes in a large population-based sample of older adults. Data were from 2577 men and 3195 women aged ≥ 50 years participating in the English Longitudinal Study of Ageing. Past-year changes in sexual desire, frequency of sexual activity, and ability to have an erection (men)/become sexually aroused (women) were assessed at baseline by self-completion questionnaire. Health outcomes (self-rated health, limiting long-standing illness, doctor-diagnosed diseases of the vascular system, and cancer) were self-reported at baseline (2012/2013) and 4-year follow-up (2016/2017). Data were analyzed using logistic regression, adjusted for sociodemographics, health behaviors, and depressive symptoms. Prospectively, men who reported a decline in sexual desire had higher odds of incident limiting long-standing illness (OR 1.41, 95% CI 1.04-1.91) and incident cancer (OR 1.63, 95% CI 1.06-2.50) than those who maintained their sexual desire. Men who reported a decline in the frequency of sexual activities had higher odds of deterioration in self-rated health (OR 1.47, 95% CI 1.04-2.08) and incident limiting long-standing illness (OR 1.69, 95% CI 1.20-2.37). In women, a decline in frequency of sexual activities was associated with deterioration of self-rated health (OR 1.64, 95% CI 1.07-2.51). Erectile dysfunction was longitudinally associated with poorer health outcomes including incident cancer (OR 1.73, 95% CI 1.11-2.70), coronary heart disease (OR 2.29, 95% CI 1.29-4.07), and fair/poor self-rated health (OR 1.66, 95% CI 1.19-2.32). Practitioners should be mindful that a decline in sexual activity, desire, or function in older age may be an important indicator of future adverse health outcomes.

Dyadic and Solitary Sexual Desire in Patients With Fibromyalgia: A Controlled Study.

INTRODUCTION: Although fibromyalgia symptoms negatively affect patients' sexual life, sexual desire in women diagnosed with fibromyalgia has been understudied. AIM: To describe and compare sexual desire in women diagnosed with fibromyalgia and healthy control women, and to investigate the influence of fibromyalgia and its pharmacologic treatment on sexual desire among women diagnosed with fibromyalgia. METHODS: 164 women diagnosed with fibromyalgia participated in the study. Participants' sexual desire, fibromyalgia symptoms, symptom interference in daily life activities, and perceived quality of life were measured. Further sociodemographic and health-related data were also recorded. 87 healthy women were selected as a control group, and their sexual desire was compared with those of women diagnosed with fibromyalgia. MAIN OUTCOME MEASURES: Main outcome measures included the Sexual Desire Inventory and the Fibromyalgia Impact Questionnaire. RESULTS: When compared with healthy control subjects, women diagnosed with fibromyalgia exhibited a significantly lower mean score on total desire (47.92 ± 17.48 vs 26.33 ± 21.95; P < .001), solitary desire (10.52 ± 5.96 vs 5.74 ± 7.01; P < .001), and dyadic desire (37.40 ± 13.98 vs 20.59 ± 16.94; P < .001). Women diagnosed with fibromyalgia who were taking antidepressants scored significantly lower on dyadic desire (P < .001), solitary desire (P < .001), and total desire (P < .001) than those who were not. Furthermore, a negative correlation between desire (dyadic and solitary) and Revised Fibromyalgia Impact Questionnaire (total and all subscales) was found. Linear regression showed that taking antidepressants, age, and the total Fibromyalgia Impact Questionnaire score explained 16% of the variance of total desire. CLINICAL IMPLICATIONS: Knowing how fibromyalgia symptoms and their pharmacologic treatment affect women's sexual desire may have implications for designing care strategies according to individual needs. STRENGTHS & LIMITATIONS: To the best of our knowledge, this is the first study that focuses on studying the impact of fibromyalgia on dyadic and solitary sexual desire. Limitations are related to having used an online questionnaire for data collection, having recruited the participants through a convenience sampling technique and not being able to isolate whether certain results are related to fibromyalgia symptoms or are side effects of the pharmacologic treatment used for symptom control. CONCLUSION: Fibromyalgia impact seems to negatively influence dyadic and solitary sexual desire in women. In addition, other factors such as age or taking antidepressant drugs may result in lower sexual desire in these patients. López-Rodríguez MM, Pérez Fernández A, Hernández-Padilla JM, et al. Dyadic and Solitary Sexual Desire in Patients With Fibromyalgia: A Controlled Study. J Sex Med 2019;16:1518-1528.

Translation and cross-cultural adaptation of the Arizona Sexual Scale (ASEX) into Portuguese / Tradução e adaptação transcultural da Arizona Sexual Scale (ASEX) para a língua portuguesa

Abstract Introduction Sexual dysfunction is common in individuals with psychiatric disorders and under psychotropic medication such as antidepressants and antipsychotics. Several scales have been developed to assess sexual function in these patients. The Arizona Sexual Scale (ASEX) is a five-item rating scale that quantifies sex drive, arousal, vaginal lubrication/penile erection, ability to reach orgasm, and satisfaction from orgasm. We describe the translation and cross-cultural adaptation of the ASEX into the Portuguese language, with the goal of contributing to the assessment of sexual function in Portuguese-speaking psychiatric patients under treatment with psychotropic drugs. Methods The translation and cross-cultural adaptation process thoroughly followed the steps recommended by the Task Force of the International Society for Pharmacoeconomics and Outcomes Research (ISPOR), namely: preparation, forward translation, reconciliation, back-translation, back-translation review, harmonization, cognitive debriefing, review of cognitive debriefing, finalization, proofreading, and final version. Results The process was successfully completed and no major differences were found between the translation, reconciliation and back-translation phases, with only small adjustments being made. Conclusion The translation of the ASEX was completed successfully, following international reference guidelines. The use of these guidelines is a guarantee of a Portuguese version that is qualitatively and semantically equivalent to the original scale. This availability of this new scale version will enable studies evaluating the sexual function of Portuguese-speaking psychiatric patients. Future studies may assess the validity of the scale for Portuguese-speaking populations.

Resumo Introdução A disfunção sexual é comum em indivíduos com doenças psiquiátricas e sob o uso de medicações como antidepressivos e antipsicóticos. Várias escalas foram desenvolvidas para avaliar a função sexual desses doentes. A Arizona Sexual Scale (ASEX) é uma escala de cinco itens de avaliação que quantifica desejo sexual, excitação, lubrificação vaginal/ereção peniana, capacidade para atingir o orgasmo e satisfação com o orgasmo. Este artigo descreve o processo de tradução e adaptação transcultural da escala ASEX para a língua portuguesa, com o objetivo de contribuir para a avaliação da função sexual dos doentes medicados com fármacos psicotrópicos nos vários países onde se utiliza essa língua. Métodos A tradução e a adaptação transcultural seguiram de forma detalhada os passos recomendados pelo grupo de trabalho da International Society for Pharmacoeconomics and Outcomes Research (ISPOR), nomeadamente: preparação, tradução inicial, reconciliação, retroversão, revisão da retroversão, harmonização, teste cognitivo, revisão do teste cognitivo, finalização, leitura final e versão final. Resultados O processo foi completado com sucesso, e não foram observadas diferenças grandes entre as fases de tradução, reconciliação e retroversão, tendo sido feitos apenas pequenos ajustes. Conclusão A tradução da escala ASEX foi bem-sucedida, seguindo orientações internacionais de referência. A aplicação dessas orientações é a garantia de uma versão em língua portuguesa que é qualitativa e semanticamente equivalente à versão original da escala. A existência desta nova versão da escala permitirá estudos que avaliem a função sexual dos doentes em países nos quais se fale a língua portuguesa. Estudos futuros poderão atestar a validade da escala para essas populações.

Sexual Health Problems and Discussion in Colorectal Cancer Patients Two Years After Diagnosis: A National Cross-Sectional Study.

BACKGROUND: Colorectal cancer (CRC) is accompanied by specific treatment-related physical (ostomy, incontinence) and psychosexual (body image, depression) consequences on sexual health. AIM: To assess sexual health of patients with CRC 2 years after diagnosis. METHODS: We selected all patients with CRC from a French nationwide longitudinal study. Data sources included patient questionnaires, medical questionnaires, and medico-administrative databases. MAIN OUTCOME MEASURE: We evaluated sexual health using the Relationship and Sexuality Scale and assessed self-reported rates of discussion about sexuality with health care providers. RESULTS: Across the 487 patients, 258 were men and 229 were women; 77% were diagnosed with colon cancer and 23% with rectal cancer. Overall, 54% of patients reported a decrease in sexual desire, 61% a decrease in frequency of intercourse, and 48% a decrease in the possibility to reach an orgasm. Patients still experiencing fecal incontinence 2 years after diagnosis had decreases in all sexual desire, intercourse, orgasm, and satisfaction Relationship and Sexuality Scale items. Patients with rectal cancer had significantly more frequent troubles with desire and orgasm than did patients with colon cancer (P = .003 and P = .014, respectively). Regarding the discussion about sexuality, only 20% of men, 11% of women, 11% of patients with colon cancer, and 33% of patients with rectal cancer recalled having discussed sexuality with the medical team. Factors independently increasing the chance to have discussed sexuality with the medical team were younger age (odds ratio [OR] = 2.77 [1.31; 5.84]; P = .007), having an ostomy (OR = 2.93 [1.27; 6.73]; P = .011), and radiotherapy (OR = 2.78 [1.23; 6.27]; P = .014). CLINICAL IMPLICATIONS: These results highlight the need for developing interventions to improve information delivery at cancer announcement and for managing sexual troubles during survivorship in patients with CRC, particularly those experiencing fecal incontinence. STRENGTH & LIMITATIONS: Strengths are the sample size and the national representation using the data of a large-scale nation-wide survey, with the possibility of comparing colon and rectal cancers. Limitations are the assessment of sexuality 2 years after diagnosis and using only self-reported measures. CONCLUSION: This study highlights the lack of discussion about sexuality with the oncology team and the need for specific sexual rehabilitation interventions, especially for patients with rectal cancer and fecal incontinence. Developing these aspects may help patients with CRC improve their sexual prognosis. Almont T, Bouhnik A-D, Charif AB, et al.

Prevalence and reproductive manifestations of macroprolactinemia.

PURPOSE: Macroprolactinemia is characterized by predominance of macroprolactin molecules in circulation and generally has extra-pituitary origin. Macroprolactin is viewed as biologically inactive, therefore asymptomatic, and thus may not require any treatment or prolonged follow-up. In addition, data on prevalence of macroprolactinemia and its clinical manifestation are also rare. Therefore, the present study was aimed to find out prevalence of macroprolactinemia and its association, if any, with reproductive manifestations. MATERIAL AND METHODS: Macroprolactin was measured in 102 hyperprolactinemia cases (>100 ng/ml prolactin level), 135 physiological hyperprolactinemia cases (50 pregnant and 85 lactating females; >100 ng/ml prolactin level) and 24 controls. Poly ethylene glycol (PEG) precipitation method was carried out to screen macroprolactin. Prolactin recovery of <25% was considered overt macroprolactinemia. Detailed clinical data was recorded which included complete medical history, physical examination and hormone measurements besides CT/MRI for pituitary abnormalities. RESULTS: Prevalence of macroprolactinemia was 21.57% (22/102) in hyperprolactinemia (prolactin >100 ng/ml). There was no case of macroprolactinemia in physiological hyperprolactinemia, or healthy control females. Reproductive manifestations were present in 72.73% (16/22) macroprolactinemia cases, out of which macroprolactinemia was the sole cause of associated reproductive manifestations in 68.7% (11/16) cases. Reversal of reproductive dysfunction/s was observed in five cases with appropriate treatment for high macroprolactin. CONCLUSION: Macroprolactinemia prevalence was found to be 21.5%, out of which 72.73% cases had associated reproductive dysfunctions.

Role of Relative Malnutrition in Exercise Hypogonadal Male Condition.

OBJECTIVE: Exercise hypogonadal male condition is a well-recognized condition in women but much less understood in men. The aim of this case report is to highlight exercise-induced hypogonadotropic hypogonadism in a male who recovered with lifestyle modifications. METHODS: We report a case of an adolescent male who developed hypogonadotropic hypogonadism secondary to excessive exercise and malnutrition that was followed up for a year without exogenous testosterone supplementation. Informed consent was obtained from the patient for his information to be used in a manuscript submitted to a journal. RESULTS: An 18-yr-old adolescent male presented to the clinic with symptoms of fatigue and low endurance, low libido, and lack of morning erections. At the time of his presentation, he was running about 60 miles per week for school cross-country team in addition to cross training with kickboxing. Physical examination was remarkable for low body mass index of 19 kg·m but was otherwise normal. Biochemical workup confirmed hypogonadotropic hypogonadism and a mild pancytopenia. Other pituitary laboratory values and MRI of the brain were unremarkable. Bone marrow biopsy performed for anemia showed features consistent with malnutrition. With a working diagnosis of exercise hypogonadal male condition, he was advised to reduce the frequency and intensity of his exercise and increase calorie intake. Cell counts and testosterone levels normalized, and his symptoms resolved without any further interventions. CONCLUSION: Significant reversible hypogonadism can develop after intensive and prolonged exercise. One of the mechanisms of hypogonadism in endurance athletes performing intensive exercise could be relative malnutrition. Further studies to evaluate the role of nutrition and body mass index in male endurance athletes presenting with hypogonadism are needed to identify the underlying mechanism of this condition.

Predictors of decreased libido in women during the late reproductive years.

OBJECTIVE: To identify risk factors for decreased libido among women in the late reproductive years. DESIGN: Prospective cohort. Women aged 35 to 47 years identified through random digit dialing were prospectively followed for 4 years with serial hormone assays and standardized questionnaires. Mean hormone values, hormone trends over 4 years, and fluctuation in hormone levels were compared among women with and without a decrease in libido at the last assessment period. Total testosterone, dihydroepiandrosterone sulfate, estradiol, follicle-stimulating hormone, luteinizing hormone, body mass index, psychosocial, and socioeconomic variables were evaluated using multivariable logistic regression. RESULTS: Of 326 women, 87 (27%) reported a decreased libido, whereas 239 (73%) did not. Participant-specific means for all hormone levels over the study period were similar among both groups. However, total testosterone fluctuation over the study was significantly different between groups. Women whose testosterone levels fluctuated from 3.8 to 21.5 ng/dL around a mean value of 9 ng/dL were four times more likely to report decreased libido compared with women with little fluctuation in testosterone [odds ratio (OR) 4.0; 95% CI, 1.6-10.0]. Depression (OR 3.4; 95%CI, 1.9-6.1), vaginal dryness (OR 3.5; 95%CI, 1.8-6.6), and children living at home (OR 1.4; 95%CI, 1.1-1.7) were also independently associated with decreased libido. CONCLUSIONS: Decreased libido in the late reproductive years is associated with a pronounced fluctuation in total testosterone over time. Other independent risk factors for decreased libido include vaginal dryness, depression, and living with children. Sexual dysfunction is a complex disorder, related to physiological and psychosocial factors, requiring further investigation.

Gonadotropin-releasing hormone (GnRH) deficiency under treatment: psychological and sexual functioning impacts.

OBJECTIVE: GnRH (gonadotropin releasing hormone) is a crucial hormone for sexual development, puberty, and fertility, and its deficiency leads to hypogonadotropic hypogonadism (HH), which causes abnormal secondary sexual development and infertility. The combination of the lack of sense of smell, i.e., anosmia, and HH is a type of GnRH deficiency known as Kallmann syndrome, which affects both men and women. The impact of Kallmann syndrome can be very severe and causes a variety of psychological problems in patients. The aim of the present study was to investigate psychopathology, sexuality, and personality characteristics in patients with GnRH deficiency under hormonal replacement therapy. DESIGN: A total of 38 patients with GnRH deficiency aged 30.6 ± 10.44 years and 38 healthy matched for age individuals participated in the study and completed a series of questionnaires concerning sexual functioning, ego defense mechanisms, quality of life, personality characteristics, as well as anxiety and depression. RESULTS: After adjustment for anxiety and depression, no difference in sexuality parameters were reported between men with and without GnRH deficiency, while women with GnRH deficiency had significantly lower sexual desire compared to controls. Concerning quality of life, satisfaction with general health was significantly lower in patients compared to controls, even after adjusting for sex. Furthermore, patients with GnRH deficiency indicated markedly less anxiety and a trend for less depression compared to controls. Finally, defense styles, ego-strength, and hostility did not differ between GnRH deficiency patients and controls. CONCLUSIONS: Our study is the first to investigate psychological and sexual functioning impacts in patients with GnRH deficiency under hormonal replacement therapy. However, larger studies are needed so as to add further empirical evidence.

Menstrual cycle phase predicts women's hormonal responses to sexual stimuli.

A robust body of research has demonstrated shifts in women's sexual desire and arousal across the menstrual cycle, with heightened desire and arousal coincident with heightened probability of conception (POC), and it is likely that ovarian hormones modulate these shifts. However, studies in which women are exposed to audiovisual sexual stimuli (AVSS) at high POC (mid-follicular) and low POC (luteal) phases have failed to detect significant differences in genital or subjective arousal patterns based on menstrual cycle phase. Here, we tested whether hormonal responsivity to AVSS differs as a function of cycle phase at testing, and whether phase during which participants were first exposed to AVSS influences hormonal responsivity in subsequent test sessions. Twenty-two naturally cycling heterosexual women were exposed to AVSS during the follicular and luteal phases, with phase at first test session counterbalanced across participants. Salivary samples were collected before and after AVSS exposure. Estradiol increased significantly during both follicular and luteal phase sessions, and increases were higher during the follicular phase. Testosterone (T) increased significantly only during the follicular phase session, while progesterone (P) did not change significantly during either cycle phase. Session order and current cycle phase interacted to predict P and T responses, such that P and T increased during the follicular phase in women who were first tested during the luteal phase. These data suggest that menstrual cycle phase influences hormonal responsivity to AVSS, and contribute to a growing body of clinical and empirical literature on the neuroendocrine modulators of women's sexuality.

General sexual desire, but not desire for uncommitted sexual relationships, tracks changes in women's hormonal status.

Several recent longitudinal studies have investigated the hormonal correlates of both young adult women's general sexual desire and, more specifically, their desire for uncommitted sexual relationships. Findings across these studies have been mixed, potentially because each study tested only small samples of women (Ns = 43, 33, and 14). Here we report results from a much larger (N = 375) longitudinal study of hormonal correlates of young adult women's general sexual desire and their desire for uncommitted sexual relationships. Our analyses suggest that within-woman changes in general sexual desire are negatively related to progesterone, but are not related to testosterone or cortisol. We observed some positive relationships for estradiol, but these were generally only significant for solitary sexual desire. By contrast with our results for general sexual desire, analyses showed no evidence that changes in women's desire for uncommitted sexual relationships are related to their hormonal status. Together, these results suggest that changes in hormonal status contribute to changes in women's general sexual desire, but do not influence women's desire for uncommitted sexual relationships.

Schreber e a escrita: transcrição do delírio e seus efeitos de estabilização / Schreber y la escrit: transcripción del delirio y sus efectos de estabilización / Schreber and the writing: transcription of delirium and its effects in stabilization

RESUMO. A partir do paradigmático caso freudiano, baseado no livro de Schreber, o artigo destaca a importância, para o autor, da redação e sobretudo a posterior publicação do seu livro autobiográfico Memórias de um Doente dos Nervos (1905/1984). A ênfase do artigo recairá tanto na atividade de escrita do próprio autor de seu Memórias, incluindo sua repercussão no campo da psicanálise a partir da interpretação de Freud e Lacan, quanto à intenção de Schreber de torná-la pública. Ambos os trabalhos, a atividade de escrita e publicação do livro serão articulados ao conceito de suplência no ensino de Jacques Lacan. A hipótese do presente artigo é a de que tanto a escrita do delírio como a posterior publicação funcionaram como reforços na sua estabilização delirante.

RESUMEN. A partir del caso freudiano paradigmático basado en el libro de Schreber, en el artículo se subraya la importancia para el autor, de la redacción y la posterior publicación de su libro auto-biográfico Memorias de un enfermo de nervios (1905/1984). El énfasis del artículo será ubicado tanto en la actividad de escribir del propio autor sus Memorias, agregando ahí la repercusión de esa obra en el campo del psicoanálisis con la interpretación de Freud y Lacan, cuanto la intención de Schreber tornarla pública. Los dos trabajos la actividad de escrita y publicación del libro serán articulados al concepto de suplencia en la enseñanza de Jacques Lacan. La hipótesis del presente artículo es la de que tanto la escrita del delirio como la publicación sirvieron como refuerzos en su estabilización delirante. La primera llamada acá de transcripción del delirio funcionó como apoyo à su imagen personal y la segunda referente a tornar publica su obra funciono como apoyo a su nombre proprio.

ABSTRACT. From the paradigmatic Freudian case based on Schreber's book, the present article highlights the importance, for the author, of the writing and especially the subsequent publication of his auto biographical book Memoirs of My Nervous Illness (1905/1984). The emphasis of this article will be on both the writing activity of the author of his Memoirs, including his repercussion in the field of psychoanalysis from the interpretation in Freud and Lacan, as well as on the intention to make it public. Both works, the activity of writing and publishing the book, will be articulated to the concept of substitution in the teaching of Jacques Lacan. Thus, the hypothesis of this article is that both the writing of delusion and its publication reinforced his delusional stabilization. The former, denominated here as transcription of delirium, worked as support to his personal image while the latter, referring to making his work public, worked as supports for his own name.

Ovarian hormone fluctuations predict within-cycle shifts in women's food intake.

What role do ovarian hormones play in modulating day-to-day shifts in women's motivational priorities? In many nonhuman mammals, estradiol causes drops in feeding and foraging, progesterone reverses this effect, and the two hormones in combination produce cycle phase shifts characterized by lower food intake near ovulation when sexual receptivity is at its peak. Hormonal predictors of within-cycle shifts in women's total food intake have not been previously tested. Here, in a study with both daily hormone measures and self-reported food intake, we found that within-cycle fluctuations in estradiol negatively predicted shifts in food intake, progesterone fluctuations positively predicted them, and the two hormones together statistically mediated a significant peri-ovulatory drop in eating. These patterns are precisely opposite to those previously reported for sexual desire from this same sample (i.e. positive and negative effects of estradiol and progesterone, respectively, on desire). To more precisely test endocrine regulation of tradeoffs between sexual and eating motivation, a difference score for the daily standardized values of the sexual desire and food intake variables was created. Fluctuations in estradiol and progesterone were oppositely associated with shifts in this difference score, supporting hormone modulation of tradeoffs between alternative motivational priorities. These tradeoffs were especially pronounced during the fertile window of the menstrual cycle on days when conception was possible, consistent with the hormone effects functioning to shift motivational salience between feeding and mating depending on within-cycle changes in fecundity. The findings provide direct evidence that phylogenetically conserved endocrine signals regulate daily shifts in human motivational priorities.
