Use of testosterone replacement therapy to treat long-COVID-related hypogonadism.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can impair pituitary-gonadal axis and a higher prevalence of hypogonadism in post-coronavirus disease 2019 (COVID-19) patients compared with the general population has been highlighted. Here we report the first case of a patient affected with a long-COVID syndrome leading to hypogonadism and treated with testosterone replacement therapy (TRT) and its effects on clinical and quality of life (QoL) outcomes. We encountered a 62-year-old man who had been diagnosed with hypogonadotropic hypogonadism about 2 months after recovery from COVID-19 underwent a complete physical examination, general and hormonal blood tests, and self-reported questionnaires administration before and after starting TRT. Following the TRT, both serum testosterone level and hypogonadism-related symptoms were improved, but poor effects occurred on general and neuropsychiatric symptoms and QoL. Therefore, hypogonadism does not appear to be the cause of neurocognitive symptoms, but rather a part of the long-COVID syndrome; as a consequence, starting TRT can improve the hypogonadism-related symptoms without clear benefits on general clinical condition and QoL, which are probably related to the long-COVID itself. Longer follow-up might clarify whether post-COVID hypogonadism is a transient condition that can revert as the patient recovers from long-COVID syndrome. Hypogonadism is more prevalent in post-COVID-19 patients compared with the general population. In these patients, hypogonadism may be part of long-COVID syndrome, and it is still unclear whether it is a transient condition or a permanent impairment of gonadal function. Testosterone replacement therapy has positive effects on hypogonadism-related clinic without clear benefits on general symptomatology and quality of life, which are more likely related to the long-COVID itself.

Microdissection testicular sperm extraction in non-obstructive azoospermic patients with solitary testis: a retrospective case-control study.

Obtaining sperm from the testis surgically and using these sperm with the intracytoplasmic sperm injection technique, has opened the way for the possibility of biological fathering in men with non-obstructive azoospermia (NOA). We aimed to evaluate our sperm retrieval rate (SRR) by microdissection testicular sperm extraction (micro-TESE) in NOA patients with solitary testis. In this retrospective case-control study, fortyfive patients with NOA who had a congenital or acquired solitary testis were included, between September 2003 and January 2022. These patients were randomly matched with patients with NOA who had bilateral testes, using a 1:3 matching ratio. We found that SRR by micro-TESE in patients with solitary testis was similar to NOA patients with bilateral testis (51.1% vs. 50.4%). Age, infertility period, ejaculate volume, serum levels of follicle stimulating hormone (FSH), luteinizing hormone (LH) and testosterone, history of varicocelectomy, history of orchiopexy, testicular stimulation therapy before micro-TESE, testicular volume, genetic status, TESE side, micro-TESE success, complications and histopathological evaluation results of both groups were evaluated, there was a statistically significant difference in only serum FSH and LH levels. There was no difference between the groups in terms of complications and hormonal effects in the early postoperative period. Micro-TESE in NOA patients with solitary testis has similar sperm retrieval and complication rates as NOA patients with bilateral testis.

Effects of Varicocele Repair on Testicular Endocrine Function: A Systematic Review and Meta-Analysis.

The objective of this manuscript is to assess the effect of varicocele repair (VR) in patients with clinical varicoceles on serum total testosterone, luteinizing hormone (LH), follicle-stimulating hormone (FSH), and inhibin B serum levels. The study was performed in compliance with the Meta-Analysis and Systematic Reviews of Observational Studies (MOOSE) guidelines and the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols (PRISMA-P). All eligible studies were selected following the PICOS (Population, Intervention, Comparison/Comparator, Outcomes, Study design) model. The values of each outcome measured after VR were compared to the before parameters and, when available, to the values on patients with unrepaired varicocele, and to those of healthy controls with no varicocele. For total testosterone, the values were sub-analyzed based on the mean total testosterone levels before VR (<300 ng/dL or >300 ng/dL), the fertility status, the time of follow-up and the technique used for VR. From a total of 460 abstracts retrieved, 48 articles were included in our meta-analysis. Serum total testosterone levels were significantly higher after VR compared to both pre-treatment levels (mean difference [MD] 82.45 ng/dL, 95% confidence interval [CI]: 64.14-100.76; p<0.00001) and to the levels of patients with unrepaired varicocele (MD 91.64 ng/dL, 95% CI: 62.30-120.99; p<0.00001). They did not differ from the levels of healthy controls with no varicocele (MD -22.01 ng/dL, 95% CI: -68.59-24.58; p=0.35). The increase resulted to be independent from the mean total testosterone levels before VR, fertility status, time of follow-up and type of VR. After VR, a trend toward lower serum LH levels was found compared to before values (MD -0.37 IU/L, 95% CI: -0.74-0.01; p=0.06). When compared to the levels of patients with unrepaired VR, LH levels after VR were significantly lower (MD -0.96 IU/L, 95% CI: -1.56 to -0.35; p=0.002). LH levels were not significantly higher than healthy men without varicocele (MD 0.84 IU/L, 95% CI: -0.68-2.36; p=0.28). Patients with VR had significantly lower FSH levels compared to their pre-treatment values (MD -1.43 IU/L, 95% CI: -1.82 to -1.04; p<0.00001), and also to those of patients with non-repaired varicocele (MD -2.35 IU/L, 95% CI: -4.06 to -0.65; p=0.007). When compared to healthy controls with no varicocele, FSH levels were significantly higher (MD 2.71 IU/L, 95% CI: 1.12-4.31; p=0.0009). Lastly, after VR no significant change in inhibin B serum levels was seen compared to pre-treatment levels (MD 11.76 pg/mL, 95% CI: -3.83-27.35; p=0.14). The present meta-analysis is the largest to date to assess the impact of VR on Leydig cell and Sertoli cell function using a before-after analysis for uncontrolled studies, and using data from patients with unrepaired varicoceles or healthy patients without varicocele as controls. VR was found to increase and restore to normality serum levels of total testosterone and LH. This evidence could be of value in considering the treatment of varicocele in patients with low testosterone or those who show a progressive decline in testosterone levels.

Changes in Testosterone Levels Following Surgical Sperm Retrieval in Men with Non-Obstructive Azoospermia: Systematic Review and Meta-Analysis.

Surgical sperm retrieval (SSR) is used to extract spermatozoa for use with intracytoplasmic sperm injection in men with obstructive and non-obstructive azoospermia (NOA). The procedure may lead to segmental devascularization, postoperative fibrosis, and atrophy with a subsequent decrease in testosterone. The aim of the study is to investigate the impact of SSR on serum levels of total testosterone (TT), follicle-stimulating hormone (FSH), luteinizing hormone (LH) testicular volume, and sexual function in infertile azoospermic men. In this systematic review and meta-analysis (SRMA), we searched articles in "PubMed" and "Scopus" exploring the impact of SSR on TT, FSH, LH, and testicular volume. The full-text articles were screened to assess eligibility before data extraction, quality assessment, and meta-analysis. Seventeen studies meeting the inclusion criteria were finally analyzed and included 1,685 infertile, azoospermic men. Patients underwent SSR and were followed in the postoperative period (one week to 32 months). The analysis showed a significant reduction in TT (mean difference [MD] 3.81 nmol/L, 95% confidence interval [CI] 0.55:7.06; p=0.02) compared to pre-SSR values. We also observed insignificant differences in serum FSH (MD 5.08 IU/L, 95% CI -5.6:15.8; p=0.35), LH (MD -2.96 IU/L, 95% CI -6.31:0.39; p=0.08), and no change in testicular volume (MD 0.07 mL, 95% CI -1.92:2.07; p=0.94) after SSR. Sexual dysfunction was associated with hypogonadism, depression, and anxiety, especially in men with unsuccessful SSR and Klinefelter syndrome. The results of this SRMA indicate a significant reduction in TT after SSR. Sexual dysfunction after testicular sperm extraction and the potential negative impact of future SSR repeat should be considered during preoperative counseling.

Relationship between elevated serum decorin levels and acne vulgaris in women with PCOS.

The primary aim of this study was to investigate the serum levels of decorin, a small leucine-rich proteoglycan, in women diagnosed with polycystic ovary syndrome (PCOS) and concurrently presenting with moderate to severe acne vulgaris. Sixty patients with acne vulgaris symptoms, subsequently diagnosed with PCOS according to the revised Rotterdam criteria, were enrolled in the study. Acne severity was assessed using the acne global severity scale (AGSS), with patients fitting AGSS category 4 (moderate) and 5 (severe) grouped into two separate cohorts of 30 individuals each. The moderate acne group comprised patients with few inflammatory lesions and a minor nodule alongside predominantly non-inflammatory lesions, whereas the severe group contained patients with multiple nodules and a mix of non-inflammatory and inflammatory lesions. A control group of twenty healthy women without acne vulgaris or PCOS was also established. The study measured serum testosterone, follicle-stimulating hormone (FSH), Luteinizing Hormone (LH), and insulin levels, and calculated insulin resistance via the Homeostasis Model Assessment of Insulin Resistance (HOMA-IR) formula. Quantitative sandwich enzyme immunoassay was employed to determine decorin levels from venous blood samples. While age, body mass index (BMI), serum FSH, LH, testosterone, and HOMA-IR values demonstrated similarity between the moderate and severe acne cohorts, comparisons between the control and both acne groups (AGSS-4 and AGSS-5) revealed significantly elevated values in the latter, excluding age, BMI, and FSH. Importantly, the serum decorin levels in both acne groups were substantially higher than in controls. A significant positive correlation was observed between serum decorin levels and both HOMA-IR (r=7.88, p<0.01) and testosterone (r=0.813, p<0.01). This study suggests that elevated circulating decorin levels play a pivotal role in the manifestation of acne vulgaris in women with PCOS.

Assessment of the In Vivo Reprotoxicity of Isotretinoin in Sprague-Dawley Male Rat.

Isotretinoin (ISO) belongs to a family of drugs called retinoids. It is the most effective drug prescribed by dermatologists for the treatment of the inflammatory disease, acne vulgaris. A significant barrier to the use of ISO has worries regarding its adverse effect profile. Despite the well-recognized reproductive toxicity and teratogenicity in females, there is no warning related to the use by male patients in the medication prospectus. Current data on the effects on human male fertility is contradictory and inconclusive. This study was undertaken to investigate the potential effects of ISO oral doses in the Sprague-Dawley male rat germ cells using the sperm morphology assay. Also, the serum levels of the follicle-stimulating hormone (FSH), luteinizing hormone (LH), and testosterone were measured. The rat groups were given varying ISO doses via gastric gavage for seven consecutive days. The epididymis sperm specimens were microscopically examined for the following reproductive toxicity parameters: sperm concentration, examined viability, motility, and morphology. The serum FSH, LH, and testosterone levels were measured by using the corresponding enzyme-linked immunosorbent assay (ELISA) kit. The data were analyzed statistically by one-way analysis of variance (ANOVA) followed by the Tukey test at P ≤ 0.05 significance level. The results indicated that the drug did not significantly increase the sex hormone levels but notably affected both the sperm quantity and quality. These observations suggest that ISO was reprotoxic, and future therapies should be further reassessed.

Reduction in the Free Androgen Index in Overweight Women After Sixty Days of a Low Glycemic Diet.

Hyperandrogenism is among the most common endocrine disorders in women. Clinically, it manifests as hirsutism, acne, and alopecia. A healthy lifestyle, including nutritious dietary patterns and physical activity, may influence the clinical manifestation of the disease. This study determined the effect of a low-glycemic index anti-inflammatory diet on testosterone levels and sex hormone-binding globulin (SHBG) and clinical symptoms in hyperandrogenic women at their reproductive age. The study included 44 overweight and obese women diagnosed with hyperandrogenism. The anthropometrics (weight, height, body mass index, waist circumference, hip circumference), physical activity, and dietary habits were assessed using valid questionnaires, scales, stadiometer, and tape meter. The significant p-value was <0.001. Serum testosterone and SHBG levels were measured using automated immunoassay instruments. The intervention based on a low-glycemic index diet with anti-inflammatory elements and slight energy deficit decreased total testosterone levels (p<0.003), increased SHBG levels (p<0.001), and decreased the free androgen index (FAI; p<0.001). Post-intervention, overall well-being was much higher than in the pre-intervention period (p<0.001), and stress was diminished (p<0.001). Western nutritional patterns positively correlate with clinical hyperandrogenism progression, whereas several factors of the low-glycemic index diet with anti-inflammatory elements and slight energy deficit positively associate with reduced clinical hyperandrogenism symptoms. In overweight and obese women, proper selection of diet, introduction of moderate physical activity, and reduction in weight, stress factors, and alcohol consumption translate into several positive effects, including reduced FAI and symptoms such as acne, hirsutism, menstrual disorders, and infertility.

The injectable contraceptives depot medroxyprogesterone acetate and norethisterone enanthate substantially and differentially decrease testosterone and sex hormone binding globulin levels: A secondary study from the WHICH randomized clinical trial.

HIV acquisition risk with norethisterone (NET) enanthate (NET-EN) is reportedly less than for depo-medroxyprogesterone acetate intramuscular (DMPA-IM). We investigated the effects of these progestin-only injectable contraceptives on serum testosterone and sex hormone binding globulin (SHBG) levels, since these may play a role in sexual behavior and HIV acquisition. The open-label WHICH clinical trial, conducted at two sites in South Africa from 2018-2019, randomized HIV-negative women aged 18-40 years to 150 mg DMPA-IM 12-weekly (n = 262) or 200 mg NET-EN 8-weekly (n = 259). We measured testosterone by UHPLC-MS/MS and SHBG by immunoassay in matched pairs of serum samples collected at baseline (D0) and at peak serum progestin levels at 25 weeks post initiation (25W) (n = 214-218 pairs). Both contraceptives substantially decreased, from D0 to 25W, the total testosterone [DMPA-IM D0 0.560, 25W 0.423 nmol/L, -24.3% (p < 0.0001); NET-EN D0 0.551, 25W 0.253 nmol/L, -54.1%, (p < 0.0001)], SHBG [DMPA-IM D0 45.0, 25W 32.7 nmol/L, -29.8% (p < 0.0001); NET-EN D0 50.2, 25W 17.6 nmol/L, -65.1% (p < 0.0001)], and calculated free testosterone levels [DMPA-IM D0 6.87, 25W 5.38 pmol/L, -17.2% (p = 0.0371); NET-EN D0 6.00, 25W 3.70, -40.0% (p < 0.0001)]. After adjusting for change from D0, the total testosterone, SHBG and calculated free testosterone levels were significantly higher for DMPA-IM than NET-EN (64.9%, p < 0.0001; 101.2%, p < 0.0001; and 38.0%, p = 0.0120, respectively). The substantial and differential decrease in testosterone and SHBG levels does not explain our previous finding of no detected decrease in risky sexual behavior or sexual function for DMPA-IM or NET-EN users from D0 to 25W. Medroxyprogesterone (MPA) and NET are androgenic and are both present in molar excess over testosterone and SHBG concentrations at 25W. Any within or between contraceptive group androgenic effects on behavior in the brain are likely dominated by the androgenic activities of MPA and NET and not by the decreased endogenous testosterone levels. The clinical trial was registered with the Pan African Clinical Trials Registry (PACTR 202009758229976).

Patient Satisfaction with Oral Testosterone Undecanoate in Men Who Received Prior Testosterone Therapy: An Open-Label, Single-Center Clinical Trial.

To evaluate patient satisfaction and symptom control in hypogonadal men transitioning from other testosterone therapies to oral testosterone undecanoate (TU). In this open-label clinical trial, men aged 18 to 75 years with hypogonadism were switched to oral TU after a sufficient washout of previous testosterone therapies. Treatment satisfaction and symptom control were primarily measured using the 9-item Treatment Satisfaction Questionnaire for Medication (TSQM-9) and quantitative androgen deficiency in aging males (qADAM) questionnaires, respectively. Secondary outcomes included changes in serum testosterone (T), estradiol (E2), hematocrit (HCT), and prostate-specific antigen (PSA) levels. Forty-one men participated, with significant improvements in all TSQM-9 scores observed over 6 months. Symptom control as measured by qADAM remained consistent. There was a significant increase in serum T and E2 levels, but HCT and PSA levels remained stable. Switching to oral TU from other testosterone therapies is associated with increased patient satisfaction and stable hypogonadal symptom control.

Efecto del extracto de Boswellia serrata sobre el daño testicular inducido por Metotrexato

This study aimed to determine the effect of Boswellia serrata extract on Methotrexate– induced testicular damage by evaluating antioxidant system, reproductive organ weights, some spermatological parametres and serum Testesterone levels. For this purpose, 40 Sprague Dawley rats were divided into 4 groups. 1. Control Group (n=10): No treatment was given for 10 days. 2. B. serrata Group (n=10): B. serrata was given by gavage at a dose of 500 mg·kg-1 for 10 days. 3. Methotrexate Group (n=10): Methotrexate was given intraperitoneally as a single dose of 20 mg·kg-1. 4. Methotrexate + B. serrata Group (n=10): After methotrexate was given intraperitoneally as a single dose of 20 mg·kg-1, 500 mg·kg-1 B. serrata was given by gavage for 10 days. It was determined that B. serrata significantly increased serum Testosterone levels (P&lt;0.001), testicular GSH levels (P&lt;0.001), motility of sperm (P&lt;0.001), concentration of sperm (P&lt;0.001), absolute ventral prostate (P&lt;0.001) and absolute seminal vesicles (P&lt;0.05) organ weight in Methotrexate + B. serrata group. The decrease in testicular MDA levels (P&gt;0.05) and the increase in GSH–Px enzyme activity of testes (P&gt;0.05) and final body weight (P&gt;0.05) were not significant in Methotrexate + B. serrata group compared to the Methotrexate group. In conclusion, the negative effects of Methotrexate on the male reproductive system can be reduced by administering B. serrata extract.

Prevalence of osteopenia and osteoporosis in middle-aged and older Korean men with testosterone deficiency syndrome: a cross-sectional study

Testosterone plays an important role in regulating fertility, muscle mass and bone density. Low bone mineral density has been reported in men with testosterone deficiency syndrome (TDS); however, there is limited research available on the prevalence of TDS. In this study, we aimed to determine the prevalence of osteoporosis and osteopenia in middle-aged and older men (n = 4707, age: 40–79 years) with TDS. Their total serum testosterone levels were measured, and TDS was defined as a testosterone level of ≤3.5 ng/mL. To assess bone mineral density, we used dual-energy X-ray absorptiometry to measure the density at the lumbar spine (L1–L4) and femoral neck (T-score: osteopenia ≤−1.0; osteoporosis ≤−2.5). We performed logistic regression analysis to calculate adjusted odds ratios (AORs) after adjusting for age, body mass index, physical activity and VO2peak (Volume oxygen peak). The results showed a significant difference in physical activity between men with TDS and those without TDS (NTDS) in both middle-aged and older age groups (p &lt; 0.05). Among middle-aged men, the AOR for osteopenia in the lumbar spine was 1.2-fold higher (Confience interval, CI (Confidence interval), 1.017–2.698), and in the femoral neck, it was 1.3-fold higher (CI, 1.012–3.013) for individuals with TDS compared to those without TDS. In older men, the AOR for osteopenia in the femoral neck increased by 1.4-fold (CI, 1.029–2.530). In conclusion, our findings suggest that middle-aged men with TDS have a higher likelihood of experiencing osteopenia in both the lumbar spine and femoral neck, while older men are more likely to have osteopenia, specifically in the femoral neck, but not osteoporosis.

The protective effect of Ozone on the mice testicular damage induced by methotrexate.

Methotrexate (MTX) is widely administered for the treatment of various cancers. However, MTX induces male reproductive toxicity. In the current study, the effect of ozone therapy (OT) on reducing the toxic effects of MTX in the mouse testicles has been investigated. Twenty-four mice were divided into four groups: control, OT (4 mg/kg ozone), MTX (20 mg/kg), and MTX + OT. Testosterone levels, histological changes, and oxidative stress biomarkers were assessed to evaluate the protective effects of OT. The results demonstrated that MTX disrupted germinal epithelium, reduced serum testosterone levels, and enhanced oxidative stress in testicular tissue. However, treatment with OT attenuated these adverse effects. OT effectively restored the levels of antioxidant enzymes, such as catalase (CAT), glutathione (GSH), and superoxide dismutase (SOD). OT reduced lipid peroxidation, as indicated by decreased malondialdehyde (MDA) levels. OT preserved normal spermatogenesis, improved morphometric parameters, and reduced histological changes by MTX. Moreover, OT effectively restored testosterone levels. OT protects against MTX-induced testicular damage by suppressing oxidative stress.

Ameliorative effect of Odontonema cuspidatum extract against testicular damage induced by sodium nitrite in rats.

Sodium nitrite (NaNO2) is a chemical substance used to enhance taste, add color, and keep food products fit for consumption for a longer time. NaNO2 gives rise to a negative adverse effect on male reproductive function. Odontonema cuspidatum (OC) is a natural plant that possesses antioxidant capacity. Our research evaluates the potential beneficial effect of OC extract on the harmful effects caused by NaNO2 on the testicular tissue and sperm characteristics of male rats. Four groups with a total of forty rats: the control, the NaNO2-received group, the OC-administered group, and the fourth group received both NaNO2 and OC. All groups were administered daily for two months. Sperm characteristics, testicular antioxidant status, qRT-PCR, and histopathological changes were evaluated. Coadministration of NaNO2 and OC, in comparison with NaNO2 alone, contributed to a notable enhancement in acrosomal integrity, decreasing sperm abnormalities and restoring serum testosterone levels. Moreover, such coadministration reduced the oxidative stress marker, malondialdehyde (MDA), and increased superoxide dismutase (SOD) in testicular tissue, lowering TNF-α gene expression, and increasing the expression of P450scc and StAR genes. In addition, the NaNO2 and OC combination decreased the testicular histopathological changes and the Caspase-3 and Proliferating cell nuclear antigen (PCNA) immunoexpression in seminiferous tubules compared with the NaNO2 group. The extract of OC exhibited the ability to decrease oxidative stress and ameliorate the detrimental effects caused by NaNO2.

Weight Loss as Therapeutic Option to Restore Fertility in Obese Men: A Meta-Analytic Study.

Weight loss has been shown to significantly elevate testosterone serum levels, though the impact on semen analysis parameters and fertility remains incompletely understood. The objective of this study was to examine the influence of body weight loss on semen parameters in obese men. A meta-analysis was performed that included clinical trials in which a semen analysis before and after weight loss was evaluated. All strategies potentially available for weight loss were considered eligible. The primary outcome was the comparison of conventional semen analysis parameters before and after weight loss. Twelve studies were considered including 345 subjects (mean age 37.6±7.9 years; mean baseline body mass index 45.4±6.0 kg/m²). Weight loss resulted in a significant increase of sperm concentration (effect size 0.495, standard error 0.251 [0.003, 0.986], p=0.049) and progressive motility (effect size 0.567, standard error 0.372 [0.370, 0.764], p<0.001). Moreover, a significant decrease of sperm DNA fragmentation index after weight loss (effect size -0.689, standard error 0.278 [-1.123, -0.255], p=0.002) was observed. This meta-analytic analysis confirmed that body weight loss may improve qualitative and quantitative sperm characteristics providing evidence for suggesting weight loss to male partners with obesity and semen analysis alteration in couples attempting conception.

Color Doppler Ultrasound of the Testis in Young Men with a Serum Testosterone Level below the Average Values of the Standard for a Prolonged Period

Introduction: This study aimed to correlate the testicular volume, ultrasound imaging, and blood flow parameters, determined using color Doppler ultrasonography in young men with a testosterone level below the average values of the standard for a prolonged period. Material and Methods: From January 2013 and December 2019, we examined 73 men aged 37 to 45 years with a testosterone level below the average values of the standard for a prolonged period and а 20 age-matched men with a testosterone level above the average values of the standard. We use color Doppler ultrasound as a method to evaluate the volume, ultrasound imaging and Doppler parameters of the testicular blood flow. Results: We obtained significantly lower but still within the reference range values for total testosterone (p&lt;0.001), compared to those of the control group. We found no differences in the ultrasound characteristics of the testicular parenchyma and significant differences between testicular volumes in patients with a testosterone level below the average values of the standard for a prolonged period and those in the control group. In the color Doppler ultrasound we recorded fluctuations only in the blood flow of a aa.intratesticularis, expressed in a slight increase in the resistance index. Conclusions: Ultrasonography of young men with a serum T level below the average values of the standard for a prolonged period found no reduction in testicular volume and no change in the ultrasound characteristic of the parenchyma, which suggests to us that this is not a congenital condition, but cannot answer the question of whether it will lead to structural changes in the testicles in the future and if so what. The non-significant increase in RI in the intratesticular arteries in all examined men is a non-specific indicator that directs the specialist’s attention to additional testing of total testosterone in patients with complaints from the male reproductive system.

In vivo exposure to electronic waste (e-waste) leachate and hydraulic fracturing fluid adversely impacts the male reproductive system

Human health effects can arise from unregulated manual disassembly of electronic waste (e-waste) and/or hydraulic fracturing fluid spills. There is limited literature on the effects of e-waste and hydraulic fracturing wastewater exposure on the male reproductive system. Thus, this proof-of-concept study begins to address the question of how wastewater from two potentially hazardous environmental processes could affect sperm quality. Therefore, three groups of eight-week-old adult mice were exposed (5 d/wk for 6 wks) via a mealworm (Tenebrio molitor and Zophabas morio) feeding route to either: (1) e-waste leachate (50% dilution) from the Alaba Market (Lagos, Nigeria); (2) West Virginia hydraulic fracturing flowback (HFF) fluid (50% dilution); or, (3) deionized water (control). At 24-hours (hr), 3 weeks (wk), or 9-wk following the 6-wk exposure period, cohorts of mice were necropsied and adverse effects/persistence on the male reproductive system were examined. Ingestion of e-waste leachate or HFF fluid decreased number and concentration of sperm and increased both chromatin damage and numbers of morphological abnormalities in the sperm when compared to control mice. Levels of serum testosterone were reduced post-exposure (3- and 9-wk) in mice exposed to e-waste leachate and HFF when compared to time-matched controls, indicating the long-term persistence of adverse effects, well after the end of exposure. These data suggest that men living around or working in vicinity of either e-waste or hydraulic fracturing could face harmful effects to their reproductive health. From both a human health and economic standpoint, development of prevention and intervention strategies that are culturally relevant and economically sensitive are critically needed to reduce exposure to e-waste and HFF-associated toxic contaminants.

Effect Of Zinc And Ingredients Of Protein Supplement On Sperm Parameters And Male Reproductive Hormones- An RCT Study

Objective: The purpose of this study was to assess the protective effects of zinc against injury to sperm parameters and male reproductive hormones brought on by toxic protein supplement constituents. Methods: 30 male Sprague Dawley rats were used in the study, of which 10 were in Group 1 (given standard laboratory food), 10 were in Group 2, fed standard laboratory food nutritional supplement powder and 10 were in Group 3, fed standard laboratory food, nutritional supplement powder and zinc. Semen Analysis of Male Sprague Dawley rats of all 3 groups was evaluated after 8 weeks. Sperm parameters and serum levels of Male Reproductive Hormones were measured at the beginning and the end of the study. Results: There was a significant decrease (P&lt;0.05) in Mean ± SEM of sperm count millions /ml, sperm motility (%), and normal sperm morphology (%) in Group 2 rats when compared with Group 1. Zinc supplement in Group 3 caused a significant increase (P&lt;0.05) in Mean ± SEM of sperm parameters including sperm count millions /ml, sperm motility (%) and normal sperm morphology (%) as compared to Group 2 rats. Mean ± SEM of serum level of testosterone Hormone, Follicle Stimulating Hormone(FSH), and Luteinizing Hormone(LH) of Group 2 rats showed a significant (P&lt;0.05) decrease when compared with Group 1 rats. However, the use of Zinc in Group 3 rats significantly (P&lt;0.05) increased serum Testosterone, FSH, and LH levels when compared to Group 2. No significant difference was noted between serum levels of Testosterone, in Group 1 and Group 3. Serum levels of FSH and LH in Group 3 rats (484.81+ 78.17 ng/ml) were significantly increased (P&lt;0.05) as compared to Group 1 rats. Conclusion: Regular addition of antioxidant Zinc with protein supplements has the potential to restore normal functions of the male reproductive system. Keywords: Protein supplements, Soy Protein, Silicon dioxide, Zinc, Sperm parameters, Testosterone, Follicle stimulating hormone, Luteinizing hormone.

Protective Effects of Chia Seeds and Omega-3 Fatty Acid against Cyclophosphamide-Induced Oligospermia in Male Wistar Rats: Potential Risks of Adverse Drug Interaction with Chia Seeds.

Objectives: The aim of this study was to investigate whether chia (Salvia hispanica) seeds, which are rich in omega-3 fatty acids, amino acids, and vitamins with antioxidant properties, can mitigate the negative effects on male reproductive function caused by cyclophosphamide, a frequently used chemotherapeutic agent. Methods: Male wistar rats are divided into seven groups (n=6). All groups except the normal control (NC) received cyclophosphamide (30mg/kg, i.p.) for the first 5 days. The standard group received clomiphene citrate (0.25 mg/kg, p.o.). Treatment groups T1%, T5%, T10%, and ω-3 received 1%, 5%, and 10% chia seeds in the diet, and 880 mg/kg omega-3 fatty acid (p.o) respectively for 15 days. The effect on the reproductive system was evaluated by analysis of epididymal sperm characteristics, biochemical parameters, and serum testosterone level. Results: Clomiphene citrate improved oligospermia via hormone mediated effect. Chia seeds and omega-3 fatty acid treatment also showed improvement in reproductive parameters including oxidative stress and histological features of the testes. Omega-3 fatty acid treatment was more effective for the prevention of cyclophosphamide toxicity on testes as compared to chia seeds. Nasal bleeding was noted in several animals subjected to chia seed treatment. This occurrence might be attributed to chia seeds' impact on coagulation and/or platelet function, potentially heightened due to chemotherapy associated bone marrow suppression. Conclusions: In our study, chia seeds as well as omega-3 fatty acid treatment were found to be protective against cyclophosphamide-induced reproductive toxicity in rats. However, the adverse effect of hemorrhage associated with drug interaction of chia seeds with cytotoxic chemotherapeutic drugs needs careful attention and further investigation.

Consequences of Anabolic Androgenic Steroids Abuse in Males, Sexual Hepatic and Metabolic Perspective

Abstract&#x0D; Background: anabolic androgenic steroids (AASs) are becoming increasingly popular between bodybuilders and people who want to enhance their physiques. However, according to the rise of the Internet and laws prohibiting sales of these substances without prescription, the route of obtaining and administration practices have become more and more dangerous.&#x0D; Objective: Anabolic-androgenic steroids represents a group of synthetic testosterone derivatives its play an important role in clinical treatment. These group of drugs are widely abused among the general public to increase lean body weight and improve athletic performance. It has been reported that AAS use can cause many adverse effects. Although there are many related studies, the current study was to review the effect of AAS on serum levels of LH, FSH, prolactin, free testosterone, ALT, AST, T3, T4, TSH, haemoglobin and platelet in bodybuilders using these hormones and compare the results with control group.&#x0D; Method: A 50 body builders were using gym routinely and were using AASs for at least 2 months interviewed and collect blood sample to measure certain lab data and see the effects of AAS on these lab data and compare results with control group who were using gym routinely but never use AAS before.&#x0D; Results: The levels of eight parameters were significantly (P-value&lt; 0.05) different according to the participating groups (AAS users vs control): LH, FSH, Prolactin, ALT, T3, TSH, haemoglobin and platelets. Five of the measured parameters were significantly (P-value&lt; 0.05) lower in the group of AAS users compared to the control (non-user) group: LH, FSH, T3, TSH, and platelets. In contrast, the other three parameters (prolactin, ALT and haemoglobin) were significantly (P-value&lt; 0.05) higher in the AAS user group compared to control group.&#x0D; Conclusion: the anabolic androgenic steroids had a harmful effect on multi physiological functions leading to hormonal disturbances.

Investigation Roles of Erythropoietin, Testosterone, and Thyroid Hormones in Patients with Chronic Liver Disease

Chronic liver disease (CLD) is characterized as a steady decline in liver functions that lasts longer than six months, including the generation of clotting factors and other proteins, detoxification of toxic metabolic products, and bile excretion. CLD is a continual process of inflammation, damage, and regeneration of the liver parenchyma that results in fibrosis and cirrhosis. The study aims to determine the predictive role of erythropoietin, testosterone, and thyroid function markers in the pathogenesis of liver dysfunction in Iraqi patients. The current research investigation was conducted out in Baquba Teaching Hospital / Diyala governorate from November 2022 to January 2023. 50 blood samples were taken from patients who came to the Baquba Teaching Hospital and those with chronic liver disease for inspection and diagnosis by the consultant doctor in the advisory units/Baquba Teaching Hospital. 30 healthy people's blood samples were taken as a control group. The serum levels of erythropoietin, testosterone, TSH, FT3, and FT4 indicators in the samples were determined using the Roche Cobas e411. The current study's findings revealed that 61-70 and &gt;70 years scored highest age groups (28% and 26%) than ≤40 years that scored least age groups (6%) with significant differences (p&lt;0.05). The levels of erythropoietin and TSH were higher in patients than healthy. In contrast, the levels of testosterone, FT3, and FT4 were low in patients than healthy with significant differences (p&lt;0.05). According to Pearson correlations, erythropoietin is a substantial positive association with FT4 (r= 0.293* Sig.=0.039). Depending on receiver operating characteristic (ROC) curve, the present study showed the Erythropoietin, Testosterone, TSH, FT3, and FT4 markers scored the highest sensitivity (86%, 90%, 94%, 96%, and 100%) and specificity (90%, 90%, 94%, 100%, and 72%) respectively, in screening patients with Chronic liver disease (CLD). We came to the conclusion that illness severity increased with age. Erythropoietin, testosterone, and thyroid function are good prognostic markers in screening chronic liver disease that is associated with gonadal and thyroid disorders.
