570-600 / 1000+ resultsresearch Studies on neurosteroids XXIV. Determination of neuroactive androgens, androsterone and 5α‐androstane‐3α,17β‐diol, in rat brain and serum using liquid chromatography–tandem mass spectrometry
The methods accurately measured brain androgens, showing most 5α-androstane-3α,17β-diol comes from outside the brain, while androsterone is both transported and made in the brain.
research Androgenic hormone profile in patients with androgenetic alopecia
Androgenetic alopecia in males is linked to hormone levels and the enzyme 5-alpha reductase.

research Effects of halogenated analogues of cortisol and progesterone upon hair growth in castrated mice.
Certain chemical changes to cortisol and progesterone can increase or decrease their ability to inhibit hair growth.
research 24-Hydroxycholesterol suppresses steroid 5α-reductase-catalyzed conversion in human glioblastoma cell lines: A novel link between brain cholesterol homeostasis and androgen metabolism
24-Hydroxycholesterol reduces DHT formation in brain cancer cells, linking cholesterol and hormone metabolism.
research Spironolactone Therapy for Hirsutism in a Hyperandrogenic Woman
Spironolactone may help reduce excessive hair growth in women with high male hormone levels.
research METABOLISM AND ACTION OF ANDROGEN IN THE SKIN
Androgens affect skin conditions like acne and hair loss through specific biochemical pathways.
research Modulation of Vitamin D Receptor Activity by the Corepressor Hairless: Differential Effects of Hairless Isoforms
Different Hairless isoforms affect Vitamin D receptor activity in hair regulation, with one repressing and the other stimulating it.
research Estrogenic Potential of 2-Alkyl-4-(thio)chromenone 6-O-Sulfamates: Potent Inhibitors of Human Steroid Sulfatase
A substance called Compound 2g can strongly block STS (a hormone-related enzyme) without affecting estrogen levels, making it potentially good for treating breast cancer.
research The role of androgen therapy
Androgens, male hormones, play a role in both men and women's health, and testosterone therapy can help women with low levels, but it's not suitable for pregnant or lactating women, or those with certain conditions.
research Hair Cycle-Specific Immunolocalization of Retinoic Acid Synthesizing Enzymes Aldh1a2 and Aldh1a3 Indicate Complex Regulation
The enzymes Aldh1a2 and Aldh1a3 are involved in making retinoic acid in hair follicles and have different roles in hair growth.
research Androgenic effect of testosterone and some of its metabolites in relation to their biotransformation in the skin.
Testosterone and some of its forms can strongly stimulate oil gland growth in skin.
research Carriers of 21-Hydroxylase Deficiency Are Not at Increased Risk for Hyperandrogenism*
People who carry the 21-Hydroxylase Deficiency gene are not more likely to have excessive male hormone levels.
research Profiling steroid and thyroid hormones with hair analysis in a cohort of women aged 25 to 45 years old
The method can measure multiple hormones in women's hair and may help identify hormone-related health issues.
research Epitestosterone—an endogenous antiandrogen?
Epitestosterone may act as a weak antiandrogen and can inhibit an enzyme involved in testosterone metabolism.
research Chemical Mechanism of the Covalent Modification of 5.alpha.-Reductases by Finasteride as Probed by Secondary Tritium Isotope Effects
Finasteride modifies 5-alpha-reductases through a two-step process, affecting inhibitor potency and possibly causing side effects.
research The Antiandrogenic Action of 4–Androsten–3–one–17β– Carboxylic Acid and Its Methyl Ester on Hamster Flank Organ1
The chemicals 17βC and its methyl ester can block the effects of testosterone on hamster skin but not the effects of DHT.
research Unusual presentation with polymenorrhagia and markedly high 17-hydroxy progesterone levels in a lady with Non-Classic Congenital Adrenal Hyperplasia.
A woman with non-classic CAH had unusual heavy periods and high hormone levels, improved with treatment.
research 3α-androstanediol, but not testosterone, attenuates age-related decrements in cognitive, anxiety, and depressive behavior of male rats
3α-androstanediol helps reduce age-related cognitive and mood declines in male rats, unlike testosterone.
