This review discusses the pathways of androgen biosynthesis and reports no new findings, highlighting the need to understand the interplay between the classic and backdoor pathways.

This study found that patients with post-finasteride syndrome exhibited major depressive disorder, severe erectile dysfunction, and neuropathy, alongside altered neuroactive steroid levels in cerebrospinal fluid.

This study found that autophagy plays a novel role in human hair growth, with altered autophagic flux during hair development phases influencing hair follicle behavior in a preclinical model.

This review explores the potential (neuro-)endocrine influences on hair follicle epithelial stem cell biology and emphasizes the need for more systematic research, but it provides no new empirical results.

This study found that Runx1 in hair follicle stem cells modulates lipid metabolism, impacting membrane organization and enhancing signal transduction for cell proliferation in both normal and cancer epithelial cells.

This study found that the synthetic thyroid hormone receptor modulator KB2115 significantly prolonged the growth phase of human hair follicles in culture without altering mitochondrial activity, suggesting potential as a safer hair loss treatment compared to traditional thyroid hormones.

This review discusses the multifaceted roles of hair follicles in skin health, including potential contributions to skin neoplasias, and reports no new results.

This review summarizes how common polymorphisms in androgen and estrogen receptor genes may influence aging-related symptoms and diseases in men, but it reports no new clinical results.

This study found that adults with trichotillomania or skin picking disorder experienced significantly poorer sleep quality, which was linked to various factors including age, stress, distress tolerance, impulsivity, and comorbid mental disorders.

This study found that cortexolone 17α-propionate showed strong topical antiandrogenic activity, outperforming progesterone and several known antiandrogens, but lacked systemic antiandrogenic effects in animal models.

Small hormonal imbalances can cause significant health problems, so more sensitive testing for hormone-disrupting chemicals is needed.

This review discusses recent research on the relationship between gut microflora and depression, highlighting the potential for new insights into the pathogenesis and treatment of major depressive disorder.

This study found that magnesium and iron deficiencies were significantly associated with menstrual cycle disorders in women of reproductive age, suggesting these deficiencies may contribute as potential factors in these disorders.

This review explores the hormonal factors linking polycystic ovary syndrome and psychiatric disorders, such as eating disorders, emphasizing a bidirectional relationship that necessitates a multidisciplinary treatment approach; it reports no new clinical results.

This systematic review found a significant association between hair loss and mental health disorders such as major depressive disorder and anxiety, but it was unable to specify correlations for each type of hair loss.

This chapter reviews genetic defects in female sexual differentiation, focusing on 46,XX disorders of sex development and the impact of genetic factors and sex steroids on development, but reports no new clinical findings.

This review discusses the biochemical properties and clinical significance of 5 alpha-reductase isozymes and reports no new clinical results.

This review discusses the effects of estrogens on skin aging and highlights the potential benefits of estrogen replacement therapy and selective estrogen receptor modulators for improving skin health in postmenopausal women, but reports no new clinical findings.

This study found that spironolactone improved cognitive performance in patients with bipolar disorder experiencing manic episodes, but did not significantly affect manic symptoms, recommending further research with larger sample sizes and longer follow-ups.

This review discusses guidelines for androgen use in women and concludes that more research is needed before recommending testosterone due to insufficient evidence on safety and efficacy.

The guidelines advise against using testosterone and DHEA in women for most conditions due to safety and effectiveness concerns, but suggest considering testosterone for postmenopausal women with low sexual desire.

This review highlights the efficacy of transdermal testosterone therapy in improving sexual function in women with hypoactive sexual desire disorder, though approved formulations and long-term safety data are limited.

This review discusses the role of androgens in women's skin-related conditions like acne, hirsutism, and female pattern hair loss, noting the lack of dermatology guidelines for when to pursue endocrinologic evaluation.

This review presents substantial evidence supporting testosterone use for hypoactive sexual desire disorder in postmenopausal women, but notes safety concerns with off-label prescribing due to lack of approved formulations.

This study used a glucocorticoid-injection model to mimic kidney-yang deficiency syndrome and reported symptoms related to hormonal imbalances in the hypothalamic-pituitary-target gland axes.

Children with alopecia areata often face more stress and depression, especially related to separation, which can affect their condition.

This study reported that machine learning analysis of protein profiles in hair segments achieved high accuracy in distinguishing women with non-suicidal self-injury disorder from healthy controls, suggesting hair proteomics as a promising non-invasive biomarker for stress-related psychopathology with potential clinical applications.
