This review discusses biotin's role in nutrition and suggests no benefit to supplementing it for hair, nails, and skin in healthy individuals; it reports preliminary findings that high dosages may help some multiple sclerosis patients.

Acne is a common skin condition linked to diet, hormones, and genetics, and early treatment can prevent scarring.

This case report describes a girl with Denys-Drash syndrome misdiagnosed with hyperandrogenism due to biotin interference in immunoassays, highlighting the need for awareness of laboratory result discrepancies.

This review discusses the clinical implications of female androgen deficiency and evaluates treatment options, emphasizing the need for cautious use of replacement therapy in women with severe deficiency and matching symptoms.

This study discusses the physiopathogeny, clinical manifestations, and treatment objectives of androgenetic alopecia without reporting new clinical findings.

Early treatment of PCOS in teens is crucial to prevent long-term health issues like diabetes and heart disease.

This source emphasizes that menopause affects the onset and course of certain skin conditions, urging dermatologists to consider menopausal status and hormone therapy when treating skin diseases, while also calling for more diverse, dermatology-focused research to improve personalized care.

This review concluded that for women, the benefits of testosterone implants are outweighed by risks, with possible higher rates of irreversible adverse effects than previously reported.

This study found that sex hormone-binding globulin promotes facial aging, while sex steroid hormones such as testosterone and estradiol inhibit it, with growth hormone levels showing no significant effect.

This review discusses polycystic ovarian syndrome, particularly in Saudi Arabia, and metformin's use and mechanism in treating related infertility, without presenting new clinical findings.

This case report described a 9-year-old girl initially suspected to have complete androgen insensitivity syndrome, whose laboratory tests later suggested an alternative diagnosis involving atypical steroid metabolism patterns and hormonal responses.

This study found that ursolic acid at 50 mg/kg improved biochemical, hormonal, and ovarian histopathological markers in a rat model of PCOS, suggesting its potential as a therapeutic option.

In this study, researchers observed that DHEA-induced PCOS rats experienced significant changes in gut microbiota and metabolic profiles, particularly affecting steroid and lipid metabolism, suggesting the gut-ovary axis may play a role in the pathogenesis of PCOS.

This review discusses polycystic ovary syndrome, focusing on its primary features of ovulatory dysfunction and hyperandrogenism, and reports no new findings.

This study found that while rat models treated with letrozole and dihydrotestosterone exhibit altered sterol, leukotriene, and steroid hormone profiles similar to human PCOS, significant differences remain.

This book reviews the symptoms, diagnosis, and treatments for Polycystic Ovary Syndrome, providing a comprehensive exploration but reports no new clinical results.

This study found that a centrifugation protocol of 1300 rpm/246 g for 20 minutes followed by 1600 rpm/373 g for 20 minutes achieved the highest platelet yield in platelet-rich plasma.

This study observed that hirsutism, alopecia, and acne are the most common androgenic symptoms in women with PCOS, with treatments including biotin, minoxidil, and over-the-counter acne medications.

In this study, researchers found that female rats exhibited more pronounced panic-related escape behavior during hypoxia, particularly in the diestrus phase, and that low-dose fluoxetine reduced this behavior, suggesting its potential for managing panic disorder symptoms related to hormonal cycles in women.

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 differential diagnosis approaches for 46,XY DSD, proposing a diagnostic algorithm focused on biochemical and genetic data, without presenting new clinical results.

This review discusses the role of neurosteroids and androgens throughout different life stages, noting the potential disruptions caused by 5α-reductase inhibitors like finasteride, but no new clinical results are reported.

This study found a significant association between AGDAC measurements and the presence of PCOS, suggesting it could be an effective clinical tool in diagnosing the condition and its phenotypes, especially when combined with AMH.

This source provides a comprehensive review of acne vulgaris, highlighting its pathophysiology, epidemiology, molecular mechanisms, and treatment options, emphasizing the significance of addressing acne's psychosocial burden for adolescents and beyond.

Androgens like testosterone affect skin health and can lead to conditions such as acne and hair loss, with various treatments available.

This review discusses how sex hormone levels and local steroid synthesis influence gender differences in aging skin, reporting no new clinical results.

This study found that obesity in women may impair endometrial stromal function and contribute to reproductive complications, possibly due to metabolic influences rather than immune cell differences.

This review discusses the controversial non-inflammatory alopecia known as alopecia X, highlighting its unknown etiology and the variable effectiveness of various proposed treatments, but reports no new results.

This study explores the complex mechanisms of skin aging, including cellular senescence and disrupted communication, and highlights rejuvenation strategies like gene expression rewiring and microbiome modulation, offering potential frameworks for regenerative therapies and precise interventions in skin and systemic aging.

This narrative review highlights the critical role of intracrine hormone production in peripheral tissues, suggesting that continuous-release subcutaneous testosterone pellet therapy may offer a more effective symptom-driven approach for aging populations, though large-scale randomized controlled trials are needed for confirmation.
