A postmenopausal woman had high testosterone from her right adrenal gland, leading to recommended surgery.
research Principles of Hair Cycle Control
Manipulating the catagen and telogen phases of hair growth could lead to treatments for hair disorders.
research Case Report: Exceptional Association of Leydig Cell Ovarian Tumor and Primary Hyperparathyroidism in a Postmenopausal Patient
A woman with a rare ovarian tumor and hyperparathyroidism improved after surgery, highlighting the need for reporting unusual cases to understand and manage rare diseases.
research Natural phenylethanoid glycoside forsythoside A alleviates androgenetic alopecia by selectively inhibiting TRPV3 channels in mice
Forsythoside A may help treat hair loss by blocking specific channels.
research HORMONE THERAPIES: SCIENTIFIC EVIDENCE BASED ON EVIDENCE AND INDISCRIMINATE USE
Properly monitored hormone therapy can improve life quality, but misuse can cause serious health issues.
research Corrigendum to “Endocrine controls of primary adult human stem cell biology: Thyroid hormones stimulate keratin 15 expression, apoptosis, and differentiation in human hair follicle epithelial stem cells in situ and in vitro” [Eur. J. Cell Biol. (2010) 769–777]

research Tight Junction barriers in human hair follicles – role of claudin-1
Claudin-1 is important for the barrier function and growth of hair.
research [Hirsutism and hypertrichosis in adults: investigations and treatment].
The document concludes that treatment for excessive hair growth depends on the cause, with options including hair removal methods and medications like anti-androgens or insulin-sensitizing drugs.
research Rooster feathering, androgenic alopecia, and hormone-dependent tumor growth: What is in common?
Sex hormones affect hair and feather growth and may help manage alopecia and hormone-dependent cancers.
research 3 alpha, 17 beta-androstanediol glucuronide in plasma. A marker of androgen action in idiopathic hirsutism.
High levels of 3 alpha-diol glucuronide in the blood are a marker of increased androgen action in women with excessive hair growth of unknown cause.
research Hair shaft disorders: a rare case series
The document concludes that proper diagnosis and treatment of hair shaft disorders require understanding their unique causes and avoiding hair-damaging practices.
research Estimation of serum aldosterone, free testosterone and DHEA-S and scalp androgen and aldosterone receptors in female androgenetic alopecia. Is the mystery solved?
High aldosterone and free testosterone levels link to female hair loss; testing aldosterone may predict hypertension risk.
research Photosensitive Trichothiodystrophy with Complex Cerebral Abnormalities
Trichothiodystrophy is a rare genetic disorder causing hair issues and sometimes linked to DNA repair defects.
research 5 Dihydrotestosterone metabolism
Certain finger length ratios and body hair patterns may predict side effects from birth control pills in women.
research Biology of Hair Growth
Testosterone and dihydrotestosterone affect hair growth, and new techniques like the folliculogram help study it, but fully understanding hair growth is still complex.
research Human hair follicles display a functional equivalent of the hypothalamic‐pituitary‐adrenal (HPA) axis and synthesize cortisol
Human hair follicles can produce cortisol like the body's stress response system.
research Sex differences in the hypothalamic–pituitary–adrenal axis’ response to stress: an important role for gonadal hormones
Male and female bodies respond differently to stress, influenced by hormones and development stages, with implications for stress-related diseases.
research Compounded Testosterone Troches TO OPTIMIZE HEALTH AND THE TESTOSTERONE CONTROVERSY.
Properly administered testosterone therapy is safe and effective but often not covered by insurance.
research Testosterone up-regulates vacuolar ATPase expression and functional activities in vas deferens of orchidectomized rats
