Phenotypes and clinical laboratory data for polycystic ovary syndrome cases: A nationwide survey in Japan.

Describe the current phenotypes and clinical laboratory data regarding polycystic ovary syndrome (PCOS) in Japan, taking into account ethnic differences and obesity status. Data for 986 PCOS cases and 965 control cases were collected using a nationwide survey in Japan. Obese/overweight (body mass index [BMI] ≥25 kg/m2) and non-obese/overweight (BMI <25 kg/m2) cases were compared. Japanese PCOS cases predominantly involved non-obese/overweight patients, accounting for 75% of all cases. Among non-obese/overweight PCOS cases, the incidence of both amenorrhea and clinical/biochemical hyperandrogenism was significantly lower than in obese/overweight PCOS cases, whereas the rate of elevated serum luteinizing hormone (LH) level was significantly higher. Even though the incidence of hirsutism in Japan is only 13.5%, the detection rate for hyperandrogenism increased by as much as 30.4% when hirsutism was added to the Japan Society of Obstetrics and Gynecology (JSOG) criteria for the diagnosis of hyperandrogenism in addition to elevated serum total testosterone level. When evaluated based on timing of blood sampling, the LH level and LH/follicle-stimulating hormone ratio determined at the initial consultation involving a chief complaint of irregular menstrual cycle (after confirming the absence of follicles measuring ≥1 cm in diameter) were significantly higher than on days 2-3 or 4-6 of the menstrual cycle. Ethnic differences, including obesity status, affected the phenotype and clinical laboratory data of Japanese PCOS patients, such as the incidence rates of clinical/biochemical hyperandrogenism and the rate of elevated basal LH level. Adding hirsutism to the JSOG 2024 criteria would enhance the accuracy of PCOS diagnosis and enhance consistency with the Rotterdam 2003 criteria. Measuring basal LH level is useful for assessing the endocrinologic characteristics of Japanese PCOS cases, as well as lean Asian PCOS cases, but the timing of blood sampling can affect the result.

Does the hemodialysis program affect the testosterone serum level in patients with end-stage renal disease?

This study aimed to evaluate the effect of high flux membrane hemodialysis on total serum testosterone (TST) levels in male patients with end-stage renal disease (ESRD). The study included 60 male ESRD patients with a mean age of 54.02 ± 13.40years, undergoing a standard hemodialysis program et al. Najah National University Hospital. All patients underwent three weekly sessions of four hours each using high flux membrane hemodialysis. TST and hematocrit (Hct) levels were measured before and after hemodialysis. Patients with prostate cancer, liver insufficiency, prior prostate surgery, or those on androgen therapy were excluded. The study assessed changes in TST and Hct levels and their correlation. Post-dialysis, there was a significant increase in serum testosterone levels from 3.13 ± 1.44ng/ml to 4.17 ± 2.04ng/ml (r = 0.78, p = 0.001). Hematocrit levels also rose significantly from 32.31% ± 3.90% to 35.27% ± 4.89% (r = 0.754, p = 0.001). The percentage change in TST and Hct levels was 35 ± 0.33% and 9 ± 0.1%, respectively, with a correlation between these changes (r = 0.277, p = 0.032). High flux membrane dialysis did not filter testosterone molecules, and the significant increase in TST levels post-dialysis is likely due to hemoconcentration. Since many patients had low or borderline TST levels before dialysis, androgen supplementation may offer clinical benefits.

Association of serum testosterone levels with left atrial size, function, and risk of atrial fibrillation in adult men: observational and mendelian randomization analyses

Abstract Background Numerous studies have investigated the association between serum testosterone levels, testosterone replacement therapy (TRT), and cardiovascular risk. However, research examining the relationship between testosterone levels and atrial fibrillation (AF) risk remains limited. We comprehensively analyzed the association between total testosterone (TT) levels, intermediary phenotypes such as left atrium (LA) size and function, and the risk of AF in middle-aged and older men. Methods We utilized data from the UK Biobank, a population-based prospective cohort, focusing on 179,988 White men who had complete serum TT level data and no AF history. Observational associations between TT levels and LA imaging traits, as well as AF risk, were estimated using multivariable regression and time-dependent Cox regression models, treating TT levels as a time-varying variable. Genetic associations were examined by Mendelian randomization (MR), using both UK Biobank and external large consortia genome-wide association study data. Results During the median follow-up of 11.8 years (IQR 10.9–12.5), we observed 13,847 incident AF cases (7.7%). Participants with normal TT levels (≥ 300 ng/dL) showed a 15% reduced risk of AF (HR of 0.85 [95% CI, 0.82–0.89]) compared to those with low TT (&amp;lt; 300 ng/dL). Interestingly, participants undergoing TRT experienced a 51% higher risk of AF (1.51 [1.09–2.07]). Furthermore, each 1-standard deviation increase in TT levels was associated with a reduced AF risk (OR of 0.91 [0.89–0.93]) and an improved LA emptying fraction (1.29 [1.06–1.58]). Applying age-specific cutoff values for low TT levels highlighted a more pronounced AF risk reduction in participants with normal TT. MR analyses supported these observations, suggesting potential causal relationships between TT levels and both LA function and AF risk. Conclusions Our findings suggest that low TT levels are associated with reduced LA function and increased risk of AF, both observationally and genetically, indicating that serum TT could serve as a surrogate marker or even a potential causal mediator in the development of AF.Abstract tableAbstract figure

Rapid Liquid Chromatography–Tandem Mass Spectrometry Method for Determination of Total and Free Testosterone in Human Serum and Its Application to Monitoring Biomarker Response of Elite Athletes

Total testosterone (TT) and free testosterone (FT) are important biochemical markers for anabolism of the human body, and can also serve as early screening indicators for overtraining syndrome (OTS). Presently, there is no fast and reliable serum TT and FT determination method in the field of sport science that can meet the requirements of sports research. Thus, a rapid and accurate determination method for serum TT and FT to fill the gap is needed urgently in sports training. Herein, a simple and reliable liquid chromatography–tandem mass spectrometry (LC-MS/MS) method for the simultaneous determination of TT and FT in serum was developed and fully validated, followed by the application of professional athletes in training monitoring. Efficient pretreatments based on only one-step liquid–liquid extraction (LLE) for TT and one-step LLE after a 20 min ultrafiltration for FT were adopted in this study, and the isotope internal standard of testosterone-13C3 was used to ensure the reliability of the whole procedure. A linear range of four orders of magnitude with 0.02–100 ng/mL can meet the concentration range requirement between a higher limit for male TT and a lower limit for female FT. The accuracy, precision, stability, and matrix effect were all within the limits of the guidelines. The serum TT and FT levels of 200 professional athletes (98 male athletes and 102 female athletes) were investigated by this method. Serum TT, FT, and FT/TT levels of professional athletes were significantly higher than the general population, and serum TT levels were significantly higher by LC-MS/MS than by a chemiluminescence immunoassay. In conclusion, the LC-MS/MS method for TT and FT measurement developed in this study is time-saving and easy to operate, which can be used as a reliable method for the determination of serum TT and FT in sports training, offering valuable information for monitoring anabolism of athletes and screening OTS in the early stage.

8661 A case of post-menopausal female with virilization due to Sertoli-Leydig cell ovarian tumor recurring in contralateral ovary 8 years later

Abstract Disclosure: M.S. Maharaul: None. J.L. Miller: None. Introduction: Sertoli-Leydig cell tumors (SLCTs) are rare androgen-secreting tumors of the ovaries, accounting for less than 0.5% of all ovarian tumors. Their incidence peaks in the second to third decade of life. New onset of severe hyperandrogenism with virilization in postmenopausal women is exceedingly rare, and the three most frequent causes are ovarian tumors, ovarian hyperthecosis and adrenal androgen producing tumors. We report one such case of ovarian androgen producing tumor which was further complicated by recurrence in the contralateral ovary. Case: A 66-year-old woman presented for evaluation of hyperandrogenism. Physical examination revealed evidence of virilization and clitoromegaly. Laboratory workup was remarkable for total serum testosterone level of 367 ng/dL with normal dehydroepiandrosterone sulfate and cortisol levels. A computerized scan of abdomen did not show any adrenal masses. Transvaginal ultrasound revealed uterine myomas but did not show any ovarian pathology. She underwent selective vein catheterization of her adrenal glands as well as ovaries and was noted to have right ovary secreting 3,982 ng/dL of testosterone whereas all other samples had total testosterone levels &amp;lt; 200 ng/dL. She underwent right salpingo-oophorectomy. Histopathologic examination revealed a 2.2 cm well differentiated Sertoli-Leydig cell tumor confined to the ovary; the fallopian tube was negative for tumor. Six weeks later, her serum total testosterone level was 18 ng/dL. 8 years later, she returns with recurrent symptoms of hyperandrogenism. Repeat workup revealed a total testosterone level of 662 ng/dL. A computerized scan of abdomen and transvaginal ultrasound revealed an unremarkable uterus and left ovary. Magnetic resonance imaging of the pelvis was done that showed a 1.2 cm enhancing mass in the left ovary. She then underwent left salpingo-oophorectomy and supracervical hysterectomy. Histopathologic examination revealed a 1.5 cm Sertoli-Leydig-cell tumor of the left ovary, the fallopian tube was negative for tumor. Six weeks later, her serum total testosterone level was 24 ng/dL and she felt significant improvement in her symptoms. Conclusion: We present an interesting case of virilization in a post-menopausal female due to Sertoli-Leydig cell tumor that resolved after unilateral oophorectomy but recurred 8 years later in the contralateral ovary with resolution after completion oophorectomy.

7472 Estrogen Monotherapy for Testosterone Suppression in Gender Diverse Patients

Abstract Disclosure: C. Zhou: None. Q. Jones: None. S. Kokosa: None. C. Kelley: None. Background: For gender diverse individuals assigned male at birth (AMAB), gender-affirming hormone therapy consists of estrogen in combination with anti-androgen medications. Exogenous estrogen use results in the development of feminine secondary sex characteristics while indirectly decreasing testosterone. Anti-androgens such as spironolactone, leuprolide, finasteride, or dutasteride work to further suppress testosterone with successful suppression levels &amp;lt;50ng/dL. However, use of these agents increases the risk of adverse side effects like hyperkalemia, polyuria, and orthostatic hypotension, thus is not suitable for everyone. Anecdotally, estrogen monotherapy has been sufficient in reducing testosterone levels to goal in some patients, however at this time there are no known studies which evaluate estrogen monotherapy and suppression of testosterone. The purpose of this study is to retrospectively review estrogen formulations and dosages in patients who have adequate testosterone suppression in the absence of anti-androgen medications. Methods: The study was a retrospective chart review of adult patients ages 18- 84.99 AMAB receiving gender-affirming estrogen between 9/2020 and 12/2023 seen within an endocrine clinic at a single academic institution. Patients younger than 18, those receiving anti-androgen medications, and those with history of orchiectomy were excluded from the study. Charts were reviewed for estrogen formulations and dosages and total serum testosterone levels. Retrospective chart review will continue with additional data expected in 2024. Results: Ten patients between the ages of 19-81 met the inclusion criteria. Of these, 7 patients identified as transfeminine and 3 identified as nonbinary. The 3 patients who identified as non-binary were not included in analysis as their treatment goals may not align with full feminization or testosterone suppression (total serum testosterone &amp;lt;50ng/dL). Testosterone suppression from estrogen monotherapy was achieved in 100% (n=7) of the transfeminine patients when serum estradiol was &amp;gt;100pg/mL. In those who achieved testosterone suppression, 5 used injectable formulations (estradiol valerate 4-6mg weekly) and 2 used transdermal patches (range of estradiol from 0.2mg twice weekly to 0.3mg three times weekly). Conclusions: Estrogen monotherapy may be effective in suppressing testosterone without the need for anti-androgen medications. So far, this was noted most commonly with use of injectable estrogen formulations. A limitation of the study is the small sample size, however ongoing data collection is anticipated. Additional research evaluating estrogen monotherapy and testosterone suppression is needed and has potentially significant implications for simplified treatment protocols for transfeminine patients.

Association between serum cotinine and total testosterone in adult males based on NHANES 2011–2016

The relationship between smoking and testosterone levels in adult males remains a topic of ongoing debate. Serum cotinine is considered a reliable marker of both smoking intensity and exposure to tobacco smoke. Therefore, we aim to examine the association between serum cotinine levels and total testosterone concentrations in adult males using data from the U.S. National Health and Nutrition Examination Survey (NHANES) database. Our study assessed the relationship between serum cotinine and total testosterone using weighted linear regression models and subgroup analysis. A fully adjusted model with smooth curve fitting was employed to investigate the potential nonlinear association between serum cotinine and total testosterone. Threshold effects were analyzed to identify the inflection point between serum cotinine and total testosterone. Indeed, a total of 7797 participants were included in our study. After adjusting for potential confounding variables, the findings indicate a positive association between serum cotinine levels and total testosterone levels (β: 0.05, 95%CI: 0.02, 0.09). Furthermore, applying smoothed curve fitting analysis and threshold effects, an inflection point was detected at a serum cotinine level of 487 ng/ml. Above this threshold, total testosterone levels declined with increasing serum cotinine levels. In conclusion, the findings of our study suggest a positive association between elevated serum cotinine levels and total testosterone levels in adult men. However, it is essential to note that this association may be reversed at excessively high serum cotinine concentrations.

High androgen level during controlled ovarian stimulation cycle impairs endometrial receptivity in PCOS patients

PCOS is one of the most common endocrine disorders among women of reproductive age. While the mechanism involved is not yet fully characterized. Our study aims to examine the pregnancy outcomes of embryo transfers in women with PCOS after pretreatment, and to explore the possible effect of high androgen levels on endometrial receptivity. Retrospective cohort study was conducted to analyze pregnancy outcomes among 2714 infertile women with tubal factor and 452 PCOS women. Endometrium samples were collected from 6 controls and 6 PCOS patients to detect the expression of endometrial receptivity marks. The implantation rate, clinical and ongoing pregnancy rates and live birth rate in women with PCOS followed fresh embryo transfers were obviously decreased even after the pretreatment. Similar pregnancy outcomes were found in frozen-thawed embryo transfer cycles between women with or without PCOS. Strikingly, serum total testosterone (TT) levels on trigger day were significantly higher in PCOS women. Women with high TT levels presented significantly lower clinical and ongoing pregnancy rates, and the expression of insulin-like growth factor binding protein 1 (IGFBP-1), and leukemia inhibitory factor (LIF) in the endometria decreased significantly as well. High doses of testosterone significantly down-regulated the expression of IGFBP-1 and LIF in Ishikawa cells. Although endocrine abnormalities had been improved before the controlled ovarian stimulation (COS) cycle started, higher serum TT levels were detected on the trigger day of the COS cycle in PCOS patients, which may contribute to the decreased fresh embryo implantation by impairing endometrial receptivity.

Anogenital distance and the risk of Late-onset hypogonadism

Objective: to investigate the association between anogenital distance (AGD) and the risk of Late-onset Hypogonadism (LOH). Methods: We prospectively recruited 145 consecutive patients referred for transrectal prostate biopsy due to prostate-specific antigen (PSA) elevation or abnormal digital rectal examination, between September 2019 and December 2021. Two variants of AGD, anus to scrotum base (AGDas) and anus to dorsal insertion of penis (AGDap) were measured. Serum total testosterone levels in fasting conditions between 07.00 and 11.00 h were determined. Patients filled out the Aging Males’ Symptoms (AMS) scale questionnaire. Results: LOH was diagnosed in 29% of the participants and presented both AGDs shorter than men without LOH, with an AGDap of 116.09 mm (9.02 mm) versus 128.71 (10.76), and an AGDas 29.70 (8.01) versus 39.93 (11.64); both p &lt; 0.05. ANCOVA test showed a significant association between the presence of LOH and both AGD measurements. Besides, AGD measurements presented adequate accuracy for the diagnosis of LOH. Conclusions: This work adds to the scientific evidence that AGD—a biomarker of fetal exposure—could provide a non-invasive measure to address LOH, providing a potential useful clinical tool.

Evaluation of serum irisin level and severity of erectile dysfunction in diabetic males: a cross sectional prospective study

BackgroundIrisin is an exercise-induced myokine that alleviates endothelial dysfunction and reduces insulin resistance in type 2 diabetes mellitus (T2DM). The current study aimed to assess the serum level of irisin in T2DM men with erectile dysfunction (ED) compared to T2DM patients with normal erectile function and healthy controls, as well as investigate the association between serum irisin level and the severity of ED in T2DM patients.Patients and methodsA cross-sectional study was conducted on 90 males, divided into three groups: 32 T2DM patients with ED, 24 T2DM patients without ED, and 34 healthy controls. Socio-demographic characteristics and scores of the validated Arabic version of the international Index of Erectile Function-5 (ArIIEF-5), Generalized Anxiety Disorder-7 (GAD-7) and Patient Health Questionnaire-9 (PHQ-9) were obtained. Furthermore, routine laboratory tests employed for diabetes monitoring and serum levels of total testosterone and irisin were assessed within these groups.ResultsT2DM men with ED had significantly lower serum levels of irisin and testosterone, as well as a lower ArIIEF-5 score, but their GAD-7 and PHQ-9 scores were significantly higher than those without ED or controls (p < 0.001). Among T2DM men, serum irisin levels positively associated with ArIIEF-5 scores and serum testosterone (r = 0.413, p = 0.002; r = 0.936, p < 0.001, respectively) but negatively associated with glycosylated hemoglobin levels (r = -0.377, p = 0.004). Multivariate regression analysis to predict ED in T2DM patients found that GAD-7 score was the only most significant predictor for ED (ꞵ = − 1.176, standard error = 0.062, p < 0.001).ConclusionThe current study had demonstrated that irisin positively correlated with the ArIIEF-5 and serum testosterone but negatively correlated with HbA1c in T2DM men. Nevertheless, further validation of these findings is necessary through cohort studies.

Androgenic Alopecia Is Associated With More Severe Lower Urinary Tract Symptoms Secondary to Benign Prostatic Hyperplasia.

To evaluate the possible association between androgenic alopecia (AGA) and lower urinary tract symptoms (LUTS) secondary to benign prostatic hyperplasia (BPH). A total of 148 patients aged over 45 with LUTS secondary to BPH were prospectively enrolled in this study. According to the Norwood-Hamilton classification, the patients were divided into two groups: AGA (n = 69) and non-AGA (n = 79). In addition, the cases of AGA were categorized as vertex (n = 39) and frontal baldness (n = 30). The International Prostate Symptom Score (IPSS), uroflowmetry parameters, prostate volume, serum total testosterone (TT), and free and total prostate-specific antigen concentrations of all patients were assessed and compared between the groups. Correlations between the AGA grade and other variables were also investigated. The serum TT level (354 ± 97.1 vs. 308.6 ± 73.1 ng/dL, p = 0.01), total IPSS (16.1 ± 8.1 vs. 13.4 ± 7.7, p = 0.04), IPSS storage subscore (IPSS-S) (7.1 ± 3.5 vs. 5.8 ± 3.6, p = 0.03), and number of nocturia episodes (2.5 ± 1.4 vs. 1.8 ± 1.4, p < 0.01) were significantly higher in the AGA group than in the non-AGA group. There were no significant differences in any of the parameters between the patients with vertex and frontal baldness. The AGA grade showed a significant positive correlation with the TT level (r = 0.407, p = 0.003), IPSS-S (r = 0.164, p = 0.04), and number of nocturia episodes (r = 0.203, p = 0.015). This study demonstrated that among patients with LUTS, those with AGA had worse symptoms and higher TT levels compared with those without AGA of similar age. Furthermore, the AGA grade was positively correlated with the TT level and storage symptoms.

Direct and indirect connections of androgen status with ejaculate parameters in men from infertile couples

In men from infertile couples the serum level of total testosterone (tT) has been shown to vary widely. Is it possible to expect that there is an association of tT content with spermogram disorders in men from infertile couples? Aim of the study was to investigate the patterns of changes in the spermiological status of men from infertile couples depending on tT level in blood serum. Material and methods. Design – observational, retrospective, one-stage study. The analysis of medical histories of 358 men with infertility in marriage was carried out. The sample was divided into comparison groups according to tT level: group 1 – less than 12.1, group 2 – from 12.1 to 20.9, group 3 – 21.0 nmol/l or more. Results. From group 1 to group 3, tT content increases more than twice, as well as concentration of indicators related to the level of T – sex hormone binding globulin (SHBG) and free testosterone (fT). There are no significant differences in luteinizing hormone (LH) and follicle stimulating hormone (FSH) level, although there is a tendency to its increase from group 1 to group 3. From group 1 of men with androgen deficiency to group 3, not only body weight and body mass index (BMI), but also waist circumference (WC) and hip circumference (HC), as well as the WC/HC index, characterizing the degree of abdominal obesity, decrease. The groups examined did not differ in the values of all studied ejaculate parameters. In group 1, a pronounced correlation between the content of tT and fT was found, in groups 2 and 3 – statistically significant inverse relationships between the level of Tob and the values of anthropometric indicators (body weight, BMI, WC and HC), as well as direct ones - with the concentration of SHBG, tT, LH and estradiol, in group 3 – with FSH levels. There were no correlations between tT content and spermogram indicators in any group of examined men. Conclusions. The results obtained suggest that only at high-normal level of testosterone in the blood it can have a stimulating effect on spermatogenesis. As a result of the accumulation of cases of androgenic deficiency in the population, the direct positive effect of serum testosterone on spermatogenesis is becomes insufficient for normal regulation, and the negative effect of testosterone deficiency on spermatogenesis, mediated through the accumulation of overweight and obesity comes to the fore.

Iraqi Women with Hirsutism, Clinical and Biochemical Characteristics: Retrospective Study

This clinical research aimed to assess the frequency of different some clinical and biochemical features of hirsitusm among Iraqi women retrospectively. Methods: This study is a descriptive cohort study included 100 Hirsutism -affected females. A retrospective analysis of patient assessed using the recently approved diagnostic guidelines for hyper androgenic women with hirsutism Clinical features, family history and hormone levels results were analyzed. Results: At our presentation, the mean age of the 100 Hirsitusm-affected females was 26.9 years ranged of (13-42) years. The mean of BMI (kg/m2) for all patients was 27.38 (Overweight), 55% of women had oligomenorrhea ,3 % had amenorrhea and 42% had none. Associated features were highly Significant (P≤0.01), highly percentage was 39% acne, the low percentage was 6% Alopecia and Acne while 47% of them were none. About 90% of all patients had TSH&gt;0.5(U/mL) while 10 % had TSH &lt;=0.5(U/mL). The mean total serum testosterone level and free testosterone were 0.598 in 72%, 27.69 in 83% of the patients respectively. The mean serum prolactin level was 24.82 but the mean serum DHEA-S (µg/dL) were 328.62 in all patients. A family history was found in 40% of the patients. conclusion: In the current study the clinical characteristics of Hirsitusm was more common in women with a high Body Mass Index nearly a half of them. The most Associated features in hirsute women was Acne and Alopecia. Also more than half of them had oligomenorrhea. While a Biochemical Characteristics study revealed that 90% of hirsute women had hypothyroidism, There is a 37% increase in DHEAS levels, a 72% increase in total testosterone, and a 35% increase in prolactin. The prolactin and total serum testosterone level elevation were not severe. About 40% of the patients had a family history.

Serum androgen dynamics in young women aged 18-40 treated with chemotherapy for breast cancer: an observational, multicentric, prospective study in France

Although the deleterious impact of chemotherapy regimen used to treat women of reproductive age with breast cancer on ovarian reserve has been extensively studied, hardly anything has been reported on the effect of these protocols on theca cell function and ovarian androgen secretion. The aim of this prospective multicentric cohort study was to describe serum levels of total testosterone and androstenedione during chemotherapy and 24-month follow-up in 250 patients <40 years treated for breast cancer. Mean basal levels of androstenedione and total testosterone at diagnosis were 1.68 ng/mL and 0.20 ng/mL respectively. No correlation with age was found. Serum levels of androstenedione and total testosterone rapidly decreased after chemotherapy completion, before slowly increasing and almost returning to basal levels in all patients during 2-year follow-up. In conclusion our study demonstrates a chemotherapy-induced alteration of ovarian thecal function, resulting in a significant decrease in serum androgen levels. This alteration of theca cell function adds to the well-known alteration of granulosa cell function, resulting in a global, but partly transient, ovarian failure in young women treated for breast cancer. These data bring new insight into ovarian physiology and emphasize the need for pre and post-treatment ovarian follow-up. Trial registration: ClinicalTrial.gov identifier NCT01114464

Improvement in Testosterone Production by Acorus gramineus for the Alleviation of Andropause Symptoms.

Acorus gramineus has a number of beneficial effects, including protective effects against age-related disorders. In this study, the effects of A. gramineus on testosterone production and andropause symptoms were evaluated. We first treated TM3 mouse Leydig cells, responsible for testosterone production, with A. gramineus aqueous extract at different concentrations. In TM3 cells, the testosterone concentration increased in a concentration-dependent manner compared with those in the control. In addition, at 400 μg/mL extract, the mRNA expression level of the steroidogenic enzyme CYP11A1 was increased. Subsequently, 23-week-old Sprague-Dawley (SD) rats exhibiting an age-related reduction in serum testosterone (approximately 80% lower than that in 7-week-old SD rats) were administered A. gramineus aqueous extract for 8 weeks. Serum total testosterone and free testosterone levels were higher and serum estradiol, prostate-specific antigen levels, and total cholesterol levels were lower in the AG50 group (A. gramineus aqueous extract 50 mg/kg of body weight/day) than in the OLD (control group). The AG50 group also showed significant elevations in sperm count, grip strength, and mRNA expression of StAR, CYP11A1, 17β-HSD, and CYP17A1 compared with those in the OLD group. In conclusion, A. gramineus aqueous extract facilitated steroidogenesis in Leydig cells, elevated testosterone levels, lowered serum estradiol and total cholesterol levels, and increased muscle strength and sperm count, thus alleviating the symptoms of andropause. These findings suggest that A. gramineus aqueous extract is a potentially effective therapeutic agent against various symptoms associated with andropause.

Testosterone, Digit Ratio, and Aggression Among Youth in Conflict with the Law in Kano, Nigeria

Abstract Introduction: Studies have associated testosterone with aggression, although with a weak and sometimes equivocal one. This study aimed to determine the correlation between testosterone and digit ratio (r2D:4D) using measures of aggression in youth in conflict with the law in Kano, Nigeria. Materials and Methods: This case–control study involves 48 youth aged 11–16 years in conflict with the law living in a remand home. The participants were divided into two groups based on the reported history of violent behavior. Serum total testosterone level was determined using an ELISA kit. Aggression was determined by the Buss–Perry Aggression Questionnaire, whereas r2D:4D was measured directly using a digital caliper. Independent-sample t test was used to determine differences in quantitative variables, while Pearson’s correlation analysis was used to determine the correlation. Results: The mean age of the participants is 15.23 years. Serum testosterone level was positively correlated with anger (r = 0.327, P = 0.023) among all participants and with physical aggression (r = 0.405, P = 0.032) among those with a history of violent behavior. However, r2D:4D did not correlate with aggression or serum testosterone. Testosterone explained 22% of variance in physical aggression and is a predictor of physical aggression (P = 0.046) among all study participants. Among those with a history of violent behavior, testosterone explained 41% of variance in physical aggression (P = 0.032); a 1 nmol increase in testosterone increases the physical aggression score by 0.41. Conclusion: testosterone level is positively correlated with anger and physical aggression in youth in conflict with the law in Kano, Nigeria, while the digit ratio is not.

The association between female sexual function and metabolic features of the polycystic ovary syndrome in Turkish women of reproductive age

Objective To investigate the association between female sexual function and metabolic features among women with polycystic ovary syndrome (PCOS) during reproductive age. Method This was a cross-sectional study in which 288 women with PCOS and 180 women without PCOS between the ages of 20 and 40 years were evaluated. All women had serum total testosterone, androstenedione, DHEA-S, fasting glucose, total cholesterol, HDL-C, LDL-C, and triglyceride levels analyzed. The McCoy Female Sexual Questionnaire (MFSQ) was applied to all studied women. Exploratory factor analysis and reliability analysis were done after data collection. The factor loadings of MFSQ domains were compared between women with PCOS and controls. Results Average factor loadings of the MFSQ sexuality domain and MFSQ sexual partner domain were significantly lower in the PCOS group when compared to controls. There was no correlation between the two sexual function domains of the MFSQ and the PCOS features either in the PCOS group or the controls. Conclusion PCOS is a heterogeneous disease with different metabolic components, such as insulin resistance, obesity, and hyperandrogenism. Although sexual function among women with PCOS was lower than controls, no differences were found in metabolic features of the PCOS and non-PCOS groups with relation to sexual function determined by the MFSQ.

Association between sex hormones and erectile dysfunction in men without hypoandrogenism

In addition to testosterone, various endocrine hormones, such as dehydroepiandrosterone sulfate (DHEA-S) and estradiol, may be involved in erectile function. However, the role of these sex hormones in the erectile function of men without hypoandrogenism remains unclear. This cross-sectional study included 398 community-dwelling men without hypoandrogenism. The participants were categorized into the non-ED and ED groups. Multivariable logistic regression analyses were performed to investigate the relationship between ED and serum sex hormone levels, including total testosterone, DHEA-S, estradiol, luteinizing hormone (LH), follicle-stimulating hormone (FSH), and prolactin. Among the 398 men, 66 (17%) and 332 (83%) were categorized into the non-ED and ED groups, respectively. In the multivariable analyses, serum DHEA-S and estradiol levels were significantly associated with ED (odds ratio [OR]: 0.996, P = 0.030; OR: 1.082, P = 0.002; respectively), whereas serum total testosterone, LH, FSH, and prolactin levels did not demonstrate significant association. After adjusting for age, none of neutrophil-to-lymphocyte ratio, serum plasminogen activator inhibitor-1 levels, and skin advanced glycation end-products levels demonstrated significant correlation with serum DHEA-S and estradiol levels. In conclusion, lower testosterone levels did not affect ED in men with normal testosterone levels, whereas serum DHEA-S and estradiol levels were significantly associated with ED.

Preoperative high serum total testosterone levels predict preserved postoperative sexual function in patients after nerve-sparing robot-assisted radical prostatectomy.

To assess the association among preoperative total testosterone levels, postoperative sexual function, and prognosis after robot-assisted radical prostatectomy. Patients who underwent robot-assisted radical prostatectomy in our institution were included in the study. Based on preoperative total testosterone levels, they were divided into low (<3.0 ng/mL) and high (≥3.0 ng/mL) total testosterone groups. Sexual function was evaluated using the International Index of Erectile Function scores, Expanded Prostate Cancer Index Composite scores, and the potency rate from preoperatively to 12 months after surgery. Oncological outcomes were evaluated based on biochemical recurrence. Out of 233 patients included, no significant difference in sexual function was found between the high (n = 183) and the low (n = 50) total testosterone groups at any point before or after surgery. However, in nerve-sparing cases, preservation in postoperative sexual function was observed only in the high total testosterone group (International Index of Erectile Function scores and Expanded Prostate Cancer Index Composite sexual function scores, at any point after surgery, p < 0.05; potency rate, at 3, 6, and 12 months after surgery; p < 0.05). Additionally, the high total testosterone group showed better biochemical recurrence-free survival than the low total testosterone group (p = 0.008). In the high total testosterone group, preservation in sexual function was observed after the nerve-sparing procedure, while the biochemical recurrence rate was low. Therefore, patients with high levels of total testosterone may be advised to consider nerve-sparing interventions.
