This study observed that hereditary factors were associated with acne duration but not severity, and found a potential role of CYP450 1A1 polymorphisms in acne pathogenesis.

This review analyzes how androgens impact sexual desire and reproductive behaviors, emphasizing molecular interactions, but provides no new clinical results.

This review discusses the hypothesis that polycystic ovary syndrome may originate in fetal life due to prenatal androgen exposure, but reports no new clinical results.

This case report documents a female toddler with novel compound heterozygous mutations in the VDR gene causing hereditary 1,25-dihydroxyvitamin D-resistant rickets, expanding the known mutation spectrum for this disease.

This study presents evidence that keratitis–ichthyosis–deafness syndrome is caused by a mutation in the connexin 26 gene, expanding the gene's known involvement in various disorders.

This review discusses the integration of omics analyses in androgenetic alopecia research, reporting no new clinical results but suggesting that collaborative multi-omics studies may enhance understanding of AGA's pathomechanisms.

This review discusses molecular testing for endocrine diseases, highlighting its diagnostic benefits and potential for prevention, particularly in conditions like multiple endocrine neoplasia type 2 and adrenogenital syndrome, but reports no new clinical results.

This study found that men with Kennedy disease have a significantly lower risk of androgenetic alopecia, likely due to androgen receptor gene alterations from the disease's polyglutamine expansion.

Male androgenetic alopecia involves hair follicle miniaturization due to DHT, with potential treatments using inhibitors and blockers.

This article provides a critical overview of recent discoveries in the genetics and molecular processes involved in androgenetic alopecia, focusing on its polygenic basis and DHT dependency, but reports no new clinical results.

This article reviews the pathophysiology, diagnosis, and treatment of female pattern hair loss, highlighting the importance of early medical intervention to arrest hair loss progression, but reports no new clinical results.

This study found that early-onset baldness in African-American men is associated with an increased risk of developing prostate cancer and more aggressive tumors, with potential interactions involving age and smoking.

Haplogroup X found in Altaian population supports Amerindian origin.

This study found that males with androgenetic alopecia had a significantly lower 2D:4D digit length ratio in the right hand compared to healthy controls, which may indicate prenatal androgen exposure.

This review discusses evidence on androgen sensitivity as a potential factor in COVID-19 disease severity, suggesting that androgen receptor interactions could influence virus entry and progression, and reports no new clinical results.

This review discusses the potential role of androgens in COVID-19's pathophysiology and their possible link to hair disorders, but reports no new clinical results.

This review examines recent advances in understanding the pathophysiology and molecular mechanisms of androgenetic alopecia, highlighting two major genetic risk loci, but does not report new clinical findings.

This review explores the current understanding of genetic and hormonal influences on male androgenetic alopecia and female pattern hair loss, providing guidance for clinicians but reports no new results.

In this study, no association was found between the AR gene and type II androgenetic alopecia in Egyptian women, suggesting it is not a useful biomarker for predisposition.

In this study, idiopathic hirsutism was identified as the most common cause of hirsutism among the participants, with a significant difference in hormone levels between cases of polycystic ovarian syndrome and idiopathic hirsutism.
