This study found that mice with a mutant CDP/Cux protein lacking the homeodomain showed severely impaired growth, high postnatal mortality, and reduced fertility, highlighting CDP/Cux's role in developmental regulation.

This article discusses the potential effects of exogenous testosterone, highlighting that its impact on prostate cancer progression, cardiovascular health, and behavior remains uncertain and needs further investigation.

Hormonal treatment in transgender women reduces semen quality, but stopping treatment may improve it.

This review discusses recent data on the use of anabolic-androgenic steroids and other steroid compounds and reports no new clinical results.

Oral retinoids can cause side effects ranging from mild to severe, including birth defects, and require careful monitoring and contraception.

This review assesses the current literature on COVID-19's effects on male sexual and reproductive health, highlighting significant research gaps and providing guidance for patient counseling.

In this case report, a male patient's semen parameters improved after discontinuing a 1-mg dose of finasteride, suggesting that stopping the medication may benefit infertile men with previous sperm production issues.

The authors reported that young men with infertility-related conditions experienced improved seminal quality after stopping finasteride, suggesting potential adverse effects on fertility during treatment.

This review discusses the impact of COVID-19 on the endocrine system and reports no clinical results; the authors emphasize the need to investigate endocrine damage during and after COVID-19 infection.

This article discusses concerns and recommendations from a French-speaking andrology society regarding COVID-19's potential impact on men's reproductive health and calls for further research in this area.

This study found that transdermal DHT treatment increased penile length in boys with 5α-reductase type 2 deficiency, but post-pubertal growth was limited and carried potential prostate complications.

This review discusses how COVID-19 may affect gonadal function and potential gender differences, but reports no clinical results; it highlights possible mechanisms and new treatment approaches from recent literature.

This article reviews the safety of finasteride by examining existing literature and does not report new findings, highlighting the ongoing controversies regarding its adverse effects.

This chapter discusses the sources, classifications, and effects of hormones, their role in disease treatment and food security, and reports no new results.

This review highlights the role of disrupted glycolysis in exacerbating reproductive and metabolic abnormalities in PCOS and suggests that agents like metformin and resveratrol may help restore glycolytic balance and improve ovarian function.

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 outlines the major health consequences of anabolic-androgenic steroid abuse, with a focus on sexual and reproductive issues, and suggests management prioritizes cessation and relapse prevention due to lack of robust randomized trials.

This review investigates how selenium, a trace element found in wheat, may impact hair health by examining its biochemical role in hair follicle biology and its potential therapeutic and toxicological effects.

This review discusses the interplay between polycystic ovary syndrome, aging, and fertility in women, and reports no new clinical results; the authors highlight pathways and interventions needing further research.

In this study, researchers observed that the sequence of maturity markers in normal boys showed specific time lags, with some markers appearing before and others after spermarche.

This study found that young adult men with moderate to severe AGA have poorer semen quality compared to those with normal to mild AGA.

This review discusses how various nutrients, such as flavonoids, probiotics, and omega-3 fatty acids, may support brain health by targeting stress-related pathways, potentially offering protective effects against neurodegenerative and psychiatric disorders through their roles in oxidative stress reduction and neuroinflammation regulation.

This article describes a framework for evaluating new health technologies by integrating quantitative evidence with qualitative assessments and using precedents to guide policy decisions, without reporting new clinical results.

This study found no clear evidence that finasteride negatively affects erectile function, though it does cause a reduction in ejaculatory volume and has potential implications for prostate cancer risk.

This study found that mice lacking sPLA2-IIE had distinct skin abnormalities, particularly affecting hair follicles, highlighting the differing roles of sPLA2 isoforms in mouse skin.

This study found that testosterone significantly influenced the expression and function of certain ion transporters in the vas deferens, impacting fluid secretion and contributing to a suitable environment for male fertility.

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.

This study explored the molecular biology of skin adaptations in pangolins, revealing that certain genes for lipid synthesis have inactive patterns, while others related to skin function remain intact, suggesting complex evolutionary changes in their skin physiology.

This study investigated pangolin skin genetics, finding that while sweat gland-related genes are not inactivated, several genes related to sebaceous gland function are, which highlights complex evolutionary adaptations in mammalian skin.

This study found that infertile couples who perceive themselves as having high intimacy report better subjective health, particularly in fulfilling social responsibilities and maintaining physical fitness.
