This chapter reviews the potential role of gonadal hormones in sex differences in play and spatial behavior, noting a lack of conclusive evidence but suggesting perinatal androgen exposure might contribute to observed differences. It reports no new research results.

In this study, micro-CT analysis revealed that severe hypospadias in finasteride-induced rats was associated with varying levels of preputial blood circulation, impacting potential surgical approaches.

This study reported a marginally lower sperm retrieval rate using micro-testicular sperm extraction (m-TESE) among nonmosaic Klinefelter Syndrome patients compared to existing literature, with younger patients benefitting more significantly from the procedure.

This review suggests that dihydrotestosterone pretreatment may improve cosmetic outcomes in hypospadias repair, but more randomized trials are needed to determine its effectiveness due to currently limited evidence.

This editorial discusses the potential progression of voiding symptoms over time in men, focusing on benign prostatic hyperplasia, but reports no new research findings.

This study found that corin, a protease, plays a crucial role in eccrine sweat glands by promoting sweat and salt excretion, which helps regulate electrolyte balance.

In this pilot study, finasteride increased testosterone/dihydrotestosterone and progesterone/dihydroprogesterone ratios in normal ovulatory women but did not alter ovulation or gonadotropin secretion.

Randomized trials reported that testosterone therapy improved sexual function in postmenopausal women with hypoactive sexual desire disorder, particularly those who had undergone oophorectomy, with reversible and well-tolerated side effects.

This study found that SARS-CoV-2 infection was associated with significant upregulation of miR-371a-3p in testicular tissues and serum, leading to androgen receptor downregulation and decreased spermatogenesis in patients.

Tamsulosin works faster, but both drugs have similar effects after 6 months.

This review analyzes existing literature on prognostic factors for renal cell carcinoma, highlighting the need for continuous updates of prognostic models to reflect advancement in molecular pathway knowledge and targeted therapies.

This research suggests that the enzyme Phospholipase D from E. coli is a strong candidate as the underlying cause of benign prostatic hyperplasia, potentially mediated by its conversion to lysophosphatidic acid in the prostate.

New hormonal therapies can help treat advanced prostate cancer but may cause testicular issues.

Researchers created a simple tool to predict bladder blockage from prostate enlargement using urine flow rate and prostate volume.

This chapter reviews the biology and biochemistry of hormones involved in male sexual development and physiology, without reporting new research findings.

This study found weak to very weak correlations between estradiol, progesterone, and testosterone levels in the cerebrospinal fluid and serum of males without cerebral disorders.

This study developed and validated a micellar electrokinetic chromatography method to determine finasteride stability, finding that the drug degrades under acidic, basic, and oxidative stress conditions.

This study developed a new analytical method to identify a wide range of endocrine disrupting compounds in full-term amniotic fluid, revealing diverse substances with potential endocrine activity.

This article reviews the commonality of androgenic alopecia in men over 30 and the use of finasteride, without reporting new research findings.

This study found that among men with coronary artery disease, education level was significantly associated with both the presence and intensity of erectile dysfunction.

This case report describes a 23-year-old woman with a history of ambiguous genitalia and complex medical conditions, including a pelvic mass and hirsutism, observed from childhood to adulthood.

This study found that chronic administration of testosterone in mice induced an elevated EPO secretion response, possibly mediated through DHT, without affecting baseline EPO levels.

This study suggests 5α‐androstan‐3α‐17β‐diol may be the true inducer of kidney enzymes in certain mice, while its induction mechanism likely involves pinocytosis rather than a receptor protein.

In this study, testosterone was reported to increase aquaporin levels and water reabsorption in the kidneys of male rats, potentially leading to higher blood pressure, with effects mitigated by flutamide and finasteride.

This study found that blocking the hypothalamic-pituitary-gonadal axis in male rats reduced baroreflex dysfunction and inflammation caused by endotoxemia, highlighting potential therapeutic benefits.

This study demonstrated that an AR-EGFP transgene can restore AR function and fertility in Sertoli cell-specific AR knockout mice, highlighting its potential use in understanding androgen receptor functions.

This document outlines recommendations from an international panel on testosterone therapy for aging men with late-onset hypogonadism, emphasizing the need for careful assessment and monitoring due to limited long-term safety data.

In this study, the presence of the HPV11-E2 protein in transgenic mice was found to increase and vary the expression of a reporter gene in hair follicle bulge regions.

This review summarizes the latest evidence on testosterone, detailing its clinical indications, diagnostic tests, and impacts on various male organs, while also noting its association with aging, metabolic disorders, and increased mortality risk due to androgen deficiency.

In this study, treatment with DHEA induced mild to moderate hyperplasia of sebaceous glands in ovariectomized rats, which was prevented by the antiandrogen Flutamide but not by the antiestrogen EM-800.
