This study reports that some human cell surface HLA-I molecules (including HLA-B27) can appear without their usual peptide component, potentially altering immune interactions, influencing arthritis development in specific mice models, and exhibiting upregulation in certain cancer cells.

Exosomes show promise in improving skin health and appearance.

This study found that an oral testosterone formulation normalized serum testosterone levels and significantly reduced SHBG in men with experimentally induced hypogonadism after nine days of treatment, suggesting potential efficacy for testosterone deficiency.

This study found that in healthy men, higher levels of free testosterone were associated with a stronger immune response to the influenza vaccine, suggesting androgens may function as immunomodulators rather than strict immunosuppressants.

In this study, hirsutism in women with PCOS was strongly associated with hyperandrogenism and metabolic abnormalities, while acne and androgenic alopecia were not effective markers for hyperandrogenism.

This study suggests that androgen receptor gene CAG repeat length may influence serum free testosterone levels in some PCOS patients, with longer repeats associated with higher testosterone concentrations.

This study found that both finasteride and a regimen of cyproterone acetate plus ethinyl estradiol effectively reduced hirsutism in women, with similar results despite differing hormonal effects.

This study found that an 8-week low-starch/low-dairy diet led to weight loss, improved insulin sensitivity, and reduced testosterone levels in women with PCOS.

This study observed that adding simvastatin to ongoing metformin treatment reduced certain androgen levels in women with non-classic congenital adrenal hyperplasia and abnormal glucose metabolism, suggesting a potential therapeutic benefit.

This study suggests that age, androgenetic alopecia, metabolic syndrome, and free testosterone levels may significantly affect sexual function in premenopausal women.

This study found that women treated with GnRHa for central precocious puberty had a higher prevalence of polycystic ovary syndrome in adulthood compared to those with isolated premature thelarche.

This review discusses the use of natural products in cosmetic preparations for skin and hair care, but reports no new research results.

In this study, hyperandrogenemia in young women with polycystic ovary syndrome was linked to higher blood pressure, independent of factors like age, insulin resistance, obesity, or dyslipidemia.

This review discusses the importance of androgen production and metabolism in hyperandrogenism, the use of specific serum markers for diagnosis, and the need for improved assays for clinical testing, but reports no new results.

This review examines current research on antioxidants in autoimmune skin diseases like alopecia areata and vitiligo, concluding with suggestions for future studies and treatment possibilities without reporting new clinical results.

This study found that untreated men with coeliac disease exhibited androgen resistance, potentially linked to sexual dysfunction, which improved as intestinal health improved, a pattern not observed in other chronic illnesses.

This study found that women with PCOS who have an exaggerated 17-hydroxyprogesterone response to buserelin exhibit more severe hyperandrogenemia, increased insulin secretion, and reduced insulin sensitivity.

This review discusses the clinical use of anti-androgen medications and highlights emerging evidence supporting plant-derived anti-androgens like spearmint tea for managing PCOS, but reports no new clinical results.

This study found that environmental factors such as smoking, alcohol consumption, exercise, and testosterone levels may significantly influence various forms of hair loss in male identical twins.

This study found that women with female pattern androgenic alopecia have significantly higher levels of certain androgens and androgen sulfates compared to normal premenopausal women, suggesting markers for diagnosis and treatment efficacy.

This study found that autophagy plays a role in sebaceous gland function and sebum composition control in mice lacking the Atg7 gene in keratinocytes.

This study suggests that hormonal changes may contribute to the persistent symptoms of long COVID, with specific patterns observed in serum hormone levels related to fatigue and sensory dysfunction.

This study identified sex-specific determinants for facial wrinkles, finding that age is the strongest factor and that lifestyle influences like smoking, alcohol use, and skin color differentially affect wrinkling in men and women.

This meta-analysis confirmed associations between some androgenic and metabolic parameters in women with PCOS, suggesting that these measurements might help predict metabolic risk in this population.

This study found a high prevalence of hyperandrogenemia in women with PCOS, with distinct biochemical differences according to BMI and presence of hyperandrogenemia.

This study found no general elevation in androgen levels among men predisposed to balding, despite a correlation with the free-to-total testosterone ratio; no link was observed with acne.

This article reviews guidelines for testosterone replacement therapy in late-onset hypogonadism, emphasizing the need for clear indications and appropriate testing before treatment, but provides no new research findings.

In this study of women with PCOS, hirsutism strongly correlated with metabolic abnormalities, while acne and androgenic alopecia were not clear markers of biochemical hyperandrogenemia or metabolic dysfunction.

This review explores factors affecting graft growth and survival in hair restoration, emphasizing the importance of fundamental care practices while considering advanced storage solutions and additives, but reports no new findings.

In this study, the authors concluded that clinical hyperandrogenism is not a reliable predictor for biochemical hyperandrogenism in Thai women with PCOS.
