In this study, researchers found no hypertrophy in axillary sweat glands of hyperhidrotic patients, with eccrine gland clear cells being the primary site of fluid transport and no evidence of apoeccrine glands.

This review discusses the physiological basis, history, and current development of male hormonal contraception, highlighting its potential risks and benefits, but reports no new research findings.

In this study, researchers observed that lower serum zinc concentrations were associated with decreased serum testosterone levels, but no link was found with sexual function questionnaire scores.

This study reviews the mechanisms by which SARS-CoV-2 may impact male fertility, noting potential disruptions in spermatogenesis and hormone secretion, and underscores the need for follow-up in recovered men.

This study found no significant evidence supporting the effectiveness of platelet-rich plasma injections for treating mild-to-moderate erectile dysfunction compared to placebo.

This review reports that while intracavernosal platelet-rich plasma is considered safe for treating erectile dysfunction, its efficacy remains unclear due to variable clinical trial protocols.

This study found that penile and clitoral differentiation in mice is influenced by androgen exposure, with penile features developing postnatally requiring prenatal and ongoing androgen presence.

This chapter discusses the role of hormones in regulating reproductive biology and outlines how the endocrine system, particularly the brain and pituitary gland, controls these hormonal processes.

In this study, topical dehydroepiandrosterone (DHEA) doubled sebum production in women without systemic side effects, suggesting it may be a safe treatment for reduced sebum output related to menopause.

This study reviews the significant prevalence of organic etiologies, especially vascular causes, in erectile dysfunction among men under 40 and emphasizes thorough evaluation and consideration of treatment options like exercise and PDE-5 inhibitors.

This reply argues that children with isolated extraordinary daytime frequency do not require extensive testing or aggressive pharmacologic treatments, noting potential negative effects of oxybutynin.

This article discusses the testosterone and estradiol levels in men, examining their roles and suggesting the need for better understanding to differentiate between normal and abnormal levels related to androgen deficiency symptoms, without reporting new clinical results.

This study found that three genetic loci, including the newly identified JMJD1C, are associated with circulating testosterone and dihydrotestosterone levels, explaining a small portion of their variance in European men.

This review summarizes characteristics of vaginal moisturizers, lubricants, and washes for managing genitourinary syndrome of menopause, and clarifies common misconceptions about their chemical additives, without providing new clinical results.

This study found no significant relationship between hormone levels and sexual function in hirsute young women compared to a control group.

Doxazosin and finasteride negatively affect sexual function in men with BPH.

This study found that a substantial number of patients continued tamsulosin and/or finasteride unnecessarily after prostate surgery, with poor documentation and communication contributing to this issue.

This study found that tadalafil use was associated with a decreased risk of major adverse cardiac events and venous thromboembolism in men with lower urinary tract symptoms.

Finasteride may decrease semen quality but not harm sperm production, and stopping the drug can improve semen quality; hyperprolactinemia can cause infertility but is treatable with medication.

This study suggests that the negative impact of high-dose Finasteride on male reproductive function may be mitigated by concurrent administration with TU.

This study found that Arc/Arg3.1 expression in hippocampal neurons is regulated by sex steroids in a sex-dependent manner, with E2 increasing expression in females and DHT in males.

This study investigated the interdigital glands in sheep, highlighting their apocrine sweat glands' ultrastructural characteristics and positive lectin reaction, but reported no new clinical results.

This study found that 5-aminolevulinic acid significantly improved chicken sperm motility and increased mitochondrial membrane depolarization, while decreasing ATP levels.

This study reports that testosterone requires conversion to DHT and estradiol for its various actions on external genitalia and bone, influencing lean mass, muscle size, strength, and body fat in hypogonadal males.

This study found that salivary testosterone levels were significantly lower in oligospermic and azoospermic men compared to normal men, suggesting its potential use in assessing male androgen status.

The conclusion is that future trials should report specific details about the PRP composition to better understand its effects on urologic conditions.

This study found that finasteride improved urodynamic measures of obstruction in men with benign prostatic enlargement and lower urinary tract symptoms, with continued improvement over two years of treatment.

In this study, researchers found no evidence of hemodynamic alterations associated with erectile dysfunction in men self-diagnosed with post-finasteride syndrome following the use of finasteride for hair loss.
