This study concluded that daily treatment with 1 mg finasteride did not affect spermatogenesis or semen production in young men and had small, reversible effects on prostate volume and serum PSA.

Finasteride daily doesn't affect sperm production or semen in young men.

This study found that oral finasteride 1 mg/day promotes hair growth and prevents further hair loss in a significant proportion of men with male pattern hair loss over two years.

This article reviews the effects of various medications on male fertility, noting that while commonly used drugs can mostly have reversible impacts, conclusive human evidence remains limited.

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 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.

In this animal study, researchers reported that acetaminophen increased LH and FSH hormones in male rats, with high doses affecting sperm production negatively, while avocado leaf extract reduced sperm motility and viability, suggesting potential adverse effects on male reproductive health.

This study found that melatonin treatment significantly increased wool production and hair follicle activity in German angora rabbits, with larger effects seen in defleeced animals and those treated in July.

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.

Machine learning is effective in predicting gene functions and their relationships with diseases.

This study developed a method to quantify hormones in skin secretions and found that hormonal composition varies by sex and anatomical site.

This study suggests that compounds from turmeric and bitter have potential antiviral activity against the influenza A virus by inhibiting the polymerase PA-PB1, warranting further experimental verification.

This study found that androgenic hormone levels did not explain growth differences between furless and furred male rabbits, despite a potential growth advantage in furless rabbits.

This study explores how natural substances affect keratin synthesis in human hair follicles, hypothesizing that oils like coconut and castor enhance synthesis, while certain mixtures decrease it, but does not confirm these results.

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.

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 abstract provides template specifications for design materials but reports no new research findings.

This article reviews the impact of aging and related urologic conditions on male fertility, highlighting the effects of various treatments on sperm parameters and recommending pre-treatment counseling for fertility preservation. It reports no new clinical results.

A thorough initial check-up is essential before sperm banking to ensure the best chance of preserving good quality sperm.

This review discusses the role of CYP gene polymorphisms in exacerbating hyperandrogenism in women with PCOS and reports no clinical results; further validation of this hypothesis is needed.

Acne is caused by genetics, diet, hormones, and bacteria, with treatments not yet curative.

This review found limited but suggestive evidence that Calcium Hydroxylapatite may promote skin regeneration through increased collagen production, cell proliferation, and angiogenesis, although most studies had methodological limitations.

The researchers reported that exposure to long days after short-day treatment induced a synchronized, out-of-season wool growth cycle in New Zealand Wiltshire sheep, similar to cycles induced in other species.

This study suggests that hair loss in Chesapeake Bay retrievers is a breed-specific syndrome characterized by unique histological features and abnormal steroid production, possibly influenced by familial factors.

This study found that biotin deficiency in mice led to reduced zinc levels, disappearance of epidermal Langerhans cells, and increased ATP production, resulting in prolonged irritant contact dermatitis.

This review discusses the biological and cosmetic aspects of hair aging and reports no new clinical results; it highlights current treatments and future research directions to address both aging factors.

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 article reviews the pathophysiology and causes of androgen-mediated hair growth in hirsutism but does not report any clinical outcomes; treatment aspects are discussed separately.
