This article summarizes findings on the role of androgens and estrogens in male reproductive tissues across species, highlighting the roles of hormone metabolism, receptor distribution, and stress-induced changes.

This study found that finasteride altered androgen receptor expression in the rat epididymis without affecting the morphology of epididymal epithelium, suggesting a change in hormonal status.

The supplement may improve hair growth and quality in women with mild to moderate hair loss.

This study reports no new results as it is a letter discussing associations between clinical variables, treatment regimens, and hair density and calibre in female androgenetic alopecia patients.

This study found that 64.8% of patients with different types of alopecia had vitamin D deficiency, and those with lichen planopilaris and telogen effluvium had higher odds of severe deficiency compared to patients with alopecia areata.

This study reported that 43% of Swiss men visiting a dermatologist experienced hair loss, and among those, 90% had androgenetic alopecia, with many switching treatments to finasteride.

This review examines the mechanisms of hair follicle development and regeneration, discussing current hair loss treatments and emerging therapies like low-level laser therapy and stem cell therapy, which the authors suggest show promise in managing hair loss.

This review discusses the evaluation and management of acne in adult women, emphasizing the importance of considering androgen excess, but it reports no new clinical findings.

In this study, individuals with androgenetic alopecia showed higher serum levels of oxidative stress markers and lower levels of antioxidants, indicating disrupted redox balance and suggesting oxidative stress may accelerate hair loss.

This article proposes naming the visual identification of androgenic alopecia in COVID-19 patients as the "Gabrin sign" to indicate higher risk for severe symptoms, but reports no new clinical results.

Two cosmetic lotions used day and night may be a good alternative to minoxidil for hair loss treatment with better cosmetic effects and tolerance.

This article summarizes data showing that numerous health issues more commonly affect men than women in the U.S., yet men's health receives significantly less attention in biomedical research.

This study found that dermatology leads in performing office-based cosmetic procedures compared to other specialties, with dermatologists and plastic surgeons having the most experience per physician.

This study found that dermatology leads in performing office-based cosmetic procedures compared to other specialties, with a focus on white, female patients aged 40 to 59.

This analytical review of alopecia treatments in the US found that drugs like minoxidil and finasteride are most affordable and effective, while newer JAK inhibitors show significant clinical results but are cost-prohibitive; the study stresses individualizing treatment based on financial capability and alopecia type.

This review highlights various plant-based and herbal treatments that reportedly help prevent hair loss and encourage hair growth. It also explores the molecular mechanisms, identified plant compounds, recent technologies such as nanoarchitectonics, and patents related to hair growth promotion.

This study found that an 8-week supplementation with specific probiotic strains improved hormonal markers and oxidative stress while decreasing inflammation in women with PCOS, although clinical symptoms like acne and hirsutism showed no significant improvement compared to the placebo group.

Male pattern hair loss affects about one-third of men aged 18-49 years in the United States.

This study found that the incidence of head and neck melanoma has increased by 51.1% among pediatric, adolescent, and young adult populations in North America over the past 20 years, primarily affecting males aged 15 to 39 years.

This study found that salivary testosterone levels were significantly lower in oligospermic and azoospermic men compared to normal men, suggesting its potential use in assessing male androgen status.

This study found that women experiencing diffuse hair loss had significantly lower levels of plasma sex-hormone binding globulin compared to controls, while their testosterone levels remained normal.

This study observed that many women with PCOS had unfavorable lipoprotein profiles, mostly moderate changes in triglycerides, HDL, and LDL cholesterol, with small LDL particles not being rare and potentially aiding risk assessment.

This study found that early clinical markers of androgenic alopecia, such as peripilar signs and hair diameter diversity, are linked to inflammatory infiltrates and hair follicle miniaturization, while iron status is linked to hair loss in pre-menopausal women.

In this study conducted at Saveetha Dental College, researchers found that the severity of male androgenetic alopecia, as graded by Norwood's classification, increased with age, although other factors such as genetic or hormonal influences were not assessed.

This review examines the epidemiology, pathogenesis, clinical manifestations, and diagnosis of female pattern hair loss and reports no new results.

This study concluded that wedge resection in patients with polycystic ovary syndrome did not significantly affect androgen status or the biochemical features of the condition, though most regained regular menstrual cycles and some became pregnant.

This review discusses types of hair loss in elderly women, highlighting diagnostic challenges and treatment limitations, but does not present new research findings.
