This review explores the impact of various medications on male fertility, highlighting reversible negative effects from methotrexate, finasteride, and ketoconazole, while reporting no adverse fertility effects for oral retinoids and certain immunosuppressants.

This study found that different epidermal stem cell populations contribute to the formation of various skin tumors and new hair follicles following β-catenin activation in the adult epidermis.

In this study, ectopic Wnt10b-mediated β-catenin activation in hair follicles resulted in larger regenerating anagen hair structures, an effect modulated by the Wnt inhibitor DKK1.

This review presents updated tables of mouse mutants with hair growth abnormalities to aid in understanding the molecular mechanisms of human hair disorders, but reports no new clinical results.

This review discusses the pathogenesis and treatment of androgenetic alopecia, highlighting genome associations and newer topical formulations, but reports no new clinical results.

This review discusses prolactin production and regulation in human skin and hair follicles, highlighting its potential broader implications but reports no new empirical results.

This review discusses various techniques for evaluating hair shedding and alopecia but reports no new clinical results. The authors emphasize the value of specific clinical and instrumental methods in assessing hair growth.

This review examines the role of retinoic acid synthesis in hair follicles and sebaceous glands, focusing on its localization and function during normal and disease states, but reports no new results.

This review discusses the role of estrogens in hair follicle cycling and the skin, highlighting the need for more research on estrogen signaling pathways and their interactions with other factors in hair biology.

This study analyzed skin from 538 knockout mouse mutants and identified 50 with epidermal phenotypes, providing valuable insights into genetic conditions and systemic effects related to skin abnormalities.

This review discusses the development and selectivity of 5 alpha-reductase inhibitors, particularly non-steroidal ones, and reports no new clinical trial results.

This study found that the topically applied non-steroidal antiandrogen RU 58841 may reduce androgen-dependent skin conditions in a hamster model with minimal systemic effects.

This study found that JunB, a transcription factor, is crucial for maintaining epidermal-pilosebaceous stem cell homeostasis by regulating progenitor cell behavior and preventing sebaceous gland dysfunction.

This article reviews the regulation of androgens in human skin and adrenals, highlighting their role in skin disorders, but reports no new research findings.

This review discusses the steroidogenic properties of human skin and suggests that impaired steroidogenesis may be linked to conditions like acne, rosacea, atopic dermatitis, and androgenic alopecia, but reports no new clinical results.

This review revisits mechanisms underlying acne lesion formation and suggests that preventing comedone development requires controlling critical factors in the pilosebaceous follicle before acne involvement.

In this review, researchers explored the roles of vitamins A, B3, C, D, and E in skin immunity, highlighting their potential as therapeutics for skin diseases due to their antioxidant, anti-inflammatory, and antimicrobial properties.

This review discusses idiopathic hirsutism, potential underlying mechanisms, and various therapeutic approaches without providing new clinical results, and emphasizes the need for further research on well-defined patient groups.

This study found that the vitamin D receptor is essential for the self-renewal, migration, and differentiation of epidermal stem cells during skin wound healing in mice.

This study found that androgen receptor activation in adult mouse skin reduces β-catenin-induced hair follicle growth and sebaceous gland conversion, highlighting its role in stem cell fate decisions.

In this study, higher expression levels of aromatase and steroidogenic acute regulatory protein were correlated with increased estrogen synthesis and fewer hair follicles in human skin, suggesting a link to elastic fiber formation and hair growth.

This review discusses the potential hormonal and metabolic factors influencing hidradenitis suppurativa and highlights the need for further research to explore hormonal dysregulation's role in the disease.

This review describes a practical approach for dermatologists to manage adult female acne using hormonal therapies and highlights the importance of identifying possible underlying endocrine disorders like PCOS, but it does not report new findings.

This review discusses the embryonic origins and characteristics of various stem cell populations in the skin, but it provides no new experimental results.

This study found that 1% ketoconazole and 1% piroctone olamine shampoos increased hair shaft thickness and reduced hair shedding in men with telogen effluvium and androgenic alopecia associated with dandruff.

This review discusses polycystic ovary syndrome treatments, focusing on the potential benefits and safety of herbs and phytochemicals, and reports no new clinical results.

This review discusses the distinct clinical and psychological aspects of adult female acne and reports no new clinical results, highlighting the need for a comprehensive management approach.

This review discusses the role of hormonal dysregulation and metabolic syndrome in hidradenitis suppurativa and reports no new clinical results.

This review discusses the challenges and potential solutions in studying Demodex mites and their possible pathogenic role in human skin disorders but reports no new findings.

This study found that reducing BMP signaling in mouse nipple epithelia, achieved through Noggin overexpression, can convert them into hairy skin with pilosebaceous units.
