Androstanediol glucuronide is a reliable marker for hirsutism in women.
research Is dehydroepiandrosterone a hormone?
Dehydroepiandrosterone (DHEA) is a prohormone important for producing sex steroids and has potential health benefits.
research 17α-Acetoxy-6-bromo-16β-methylpregna-4,6-diene-3,20-dione
A new compound with strong antiandrogenic effects was found, potentially useful for treating conditions like acne and prostate cancer.
research Biosynthesis of Dihydrotestosterone by a Pathway that Does Not Require Testosterone as an Intermediate in the SZ95 Sebaceous Gland Cell Line
Dihydrotestosterone can be made from dehydroepiandrosterone in skin cells without needing testosterone.
research Helpful diagnostic markers of steroidogenesis for defining hyperandrogenemia in hirsute women
The study concluded that androstendione and DHEA are important for diagnosing high male hormone levels in women with excessive hair growth.
research Measurement and comparison of various androgen levels in women with severe acne, hirsutism, and androgenic alopecia
Women with severe acne, hirsutism, and androgenic alopecia often have higher levels of certain androgens, but the specific pattern can't be predicted just by looking at symptoms.
research A high-performance liquid chromatography–tandem mass spectrometry assay of the androgenic neurosteroid 3α-androstanediol (5α-androstane-3α,17β-diol) in plasma
Testosterone increases 3α-androstanediol levels, which can be blocked by finasteride.
research 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 DHEA : why, when, and how much ? D’après la conférence de Bruno Allolio (Wuerzburg), 50e Journées internationales d’endocrinologie clinique Henri-Pierre KLOTZ, septembre 2007
DHEA supplementation may improve quality of life, neuropsychological functions, and sexual satisfaction in individuals with adrenal insufficiency, but more research is needed to confirm its safety and effectiveness.
research Prostaglandin D2 Uses Components of ROS Signaling to Enhance Testosterone Production in Keratinocytes
Prostaglandin D2 increases testosterone production in skin cells through a process involving reactive oxygen species, and antioxidants may help treat hair loss.
research Crystal Structure and Synthesis of 17α-Acetoxy-4-bromopregn-4-ene-3,20-dione
The document concludes that a compound with potential for treating prostate cancer and hair loss was successfully made and its detailed structure was confirmed.
research METABOLISM OF DEHYDROEPIANDROSTERONE BY ISOLATED HUMAN HAIR FOLLICLES
Human hair follicles can process steroid hormones like DHEA.
research Metabolic study of androsta-1,4,6-triene-3,17-dione in horses using liquid chromatography/high resolution mass spectrometry
The study found that urine metabolites M1b or M4 are the best indicators of ATD use in horses, with detection possible up to 77 hours in urine and 28 hours in blood.
research Androstanediolglucuronide: A parameter for peripheral androgen activity before and during therapy with cyproterone acetate
3α-AdiolG is a good marker for androgen activity in women with excessive hair growth and decreases with anti-androgen treatment.
research Pharmacokinetics and Bioconversion of Dehydroepiandrosterone after Application of Dexamethasone in Women with Polycystic Ovary Syndrome
Women with PCOS have higher 5alpha-reductase activity, affecting steroid levels.
research Metabolism of androgens by isolated human hair follicles
Beard hair follicles convert testosterone to 5α-dihydrotestosterone most intensively.
research Design, synthesis and biological evaluation of novel androst-3,5-diene-3-carboxylic acid derivatives as inhibitors of 5α-reductase type 1 and 2
New chemical compounds were made that effectively block an enzyme linked to prostate growth.
research Synthesis and in Vitro Evaluation of 4-Substituted N-(1,1-Dimethylethyl)-3-oxo-4-androstene-17.beta.-carboxamides as 5.alpha.-Reductase Inhibitors and Antiandrogens
The new compounds moderately block a specific enzyme and strongly counteract a male hormone, suggesting potential for treating certain male-related health conditions.
research Crystal Structure and Synthesis of 17α-Acetoxy-pregn-4,6-diene-3,20-dione
The compound was successfully made and shows potential for treating prostate cancer.
research Mechanisms of Action of Dehydroepiandrosterone
