In this study, 85.9% of 120 hirsute Saudi women exhibited elevated androgen levels, suggesting the need for a comprehensive hormonal evaluation to identify underlying causes of hirsutism.

This study found that an 8-month treatment with a low-dose oral contraceptive significantly reduced testosterone levels and hair growth in women with polycystic ovary syndrome and hirsutism, with minimal side effects.

Women have a higher DHT/testosterone ratio than men, possibly due to gut bacteria activity.

This historical review traces the discovery of 5-alpha reductase inhibitors, widely used in urology, from the study of guevedoces, Dominican children with a rare disorder leading to significant androgenization at puberty.

In this study, PGD2 was shown to increase testosterone production in human keratinocytes through reactive oxygen species, suggesting potential benefits of antioxidants like N-acetyl-cysteine for AGA patients.

This study found that the selective PPARγ modulator GMG-43AC may inhibit unwanted hair growth by inducing catagen phase while preserving hair follicle epithelial progenitor cells, suggesting potential in anti-hirsutism therapy.

In this case report, researchers observed that a female patient with severe hidradenitis suppurativa experienced complete resolution of her lesions after starting intramuscular exogenous testosterone as part of gender transition, suggesting its potential role in disease remission when other treatments were ineffective.

This study found that high-dose cyproterone acetate was effective for treating hirsutism, but 33% of patients felt their condition worsened on low-dose maintenance therapy, despite no significant change in objective measures of hair growth.

This study found that MK-386 selectively suppressed sebum DHT levels in a dose-dependent manner, suggesting potential use for treating acne.

This study developed a method to quantify hormones in skin secretions and found that hormonal composition varies by sex and anatomical site.

This study found that testosterone propionate increased hair mass in female hamsters' flank organs, while cyproterone acetate applied topically reduced androgen-stimulated hair in a dose-dependent manner.

This study found that spironolactone reduced hirsutism scores in women without significant hormonal changes, suggesting its effectiveness primarily through peripheral mechanisms.

This trial found that intradermal injections of the Hair Stimulating Complex were well-tolerated and effectively stimulated hair growth and prevented hair loss in male pattern baldness participants over 18 weeks.

This article discusses solitary hirsutism, emphasizing that treatment is mostly cosmetic unless contraception is also desired, and reports no new clinical results.

This study found that the methanolic extract of Hibiscus rosa sinensis exhibits promising 5α-reductase inhibitory activity, suggesting its potential use in the treatment of androgenic conditions like male pattern hair loss and benign prostatic hyperplasia.

In human hair follicle cultures, this study found that cyclohexyl salicylate, an OR2A4/7 agonist, promoted hair growth by delaying catagen development and expanding epithelial stem cell progeny, suggesting its potential as a non-drug hair loss treatment.

This review discusses 46,XY disorders of sex development caused by defects in androgen production and highlights the need for long-term care from experienced multidisciplinary teams, but it reports no new clinical findings.

This study observed that flutamide treatment reduced hair growth and improved acne and seborrhea in hirsute women, with increased androstenedione levels and no side effects noted.

This study synthesized new heterocyclic steroid derivatives and reported their promising antiproliferative activity against breast and prostate cancer cell lines, highlighting selectivity and impact on signaling pathways even in cells resistant to certain treatments.

This review discusses causes and treatments for hirsutism in women and reports no new clinical results.

This study observed that most hirsute patients on combined cyproterone acetate and 'Diane' therapy experienced a reduction in hair growth, with hair becoming softer, thinner, and lighter in color over 12 months.

This research indicates that androgens may drive hidradenitis suppurativa in some patients, as they show higher testosterone levels compared to nonaffected controls, and testosterone-lowering medications are established treatments for milder cases.

This study found that X-irradiation causes hair dysplasia through two mechanisms influenced by oxygen, and cystamine injections after irradiation enhance this effect.

This study found that finasteride effectively inhibits the enzymatic activity of human steroid 5 alpha reductase type II in newly established CHO cell lines.

In this case study, a woman with high 25(OH)D levels and persistent symptoms showed decreased parathormone after transdermal estrogen therapy, highlighting the importance of assessing both parathormone and estrogen levels in similar patients.

In this study, spironolactone treatment reduced hair growth in 17 out of 30 patients with hirsutism, but was less effective compared to cyproterone acetate–estrogen therapy.

This study found no correlation between clinical stages of androgenetic alopecia and serum DHEA-S levels in men, contrasting with previous studies suggesting elevated levels.

This study developed innovative silica/natural polysaccharide hybrid nanoparticles encapsulating plant-derived 5-alpha-reductase inhibitors, reporting effective controlled release at hair follicle pH and lower cytotoxicity, suggesting a promising delivery system for antiandrogenic treatments.

This study found that several synthesized pregnane derivatives exhibited significant inhibitory effects on testosterone conversion to dihydrotestosterone and reduced related androgenic parameters in multiple pharmacological models.

This study found that SDR5A1 gene expression was similar between hirsute women, normal women, and men, suggesting it may not explain differences in hair growth among these groups.
