research Metabolism of androgens by isolated human beard hair follicles
Human beard hair follicles change testosterone into other related hormones, but don't much change androstenedione into testosterone.
research Synthesis, Characterization and Evaluation of 5α, 6β-Dihalo Androsterone Derivatives as 5α-Reductase Inhibitors
Compound 7b is a promising candidate for treating benign prostatic hyperplasia and prostate cancer.
research 13C-NMR study of 4-azasteroids in solution and solid state
4-azasteroids, including finasteride, can inhibit 5α-reductase, helping treat conditions like enlarged prostate and hair loss.
research 11α-Hydroxyprogesterone, a potent 11β-hydroxysteroid dehydrogenase inhibitor, is metabolised by steroid-5α-reductase and cytochrome P450 17α-hydroxylase/17,20-lyase to produce C11α-derivatives of 21-deoxycortisol and 11-hydroxyandrostenedione in vitro
11α-Hydroxyprogesterone is changed into different substances by certain enzymes and may play a role in prostate cancer.
research Dehydroepiandrosterone (DHEA) and Testosterone Concentrations in Human Hair after Chronic DHEA Supplementation
Chronic DHEA supplementation slightly increases testosterone in hair but stays within safe limits.
research Metabolism of androgens by isolated human hair follicles
Beard hair follicles convert testosterone to 5α-dihydrotestosterone most intensively.
research New Nonsteroidal Molecules as Blockers of the Steroidogenic Pathway
New nonsteroidal molecules can potentially increase dihydrotestosterone in neurons by blocking certain enzymes, without affecting prostate and seminal vesicle weight.
research 17-Oximino-5-androsten-3β-yl esters: synthesis, antiproliferative activity, acute toxicity, and effect on serum androgen level
Some synthesized compounds were more effective than Finasteride in reducing prostate cancer cell growth and androgen levels.
research New ester derivatives of dehydroepiandrosterone as 5α-reductase inhibitors
New compounds may help treat prostate issues without affecting androgen receptors.
research METABOLISM OF DEHYDROEPIANDROSTERONE BY ISOLATED HUMAN HAIR FOLLICLES
Human hair follicles can process steroid hormones like DHEA.
research The Biological Actions of Dehydroepiandrosterone Involves Multiple Receptors
DHEA affects multiple receptors and may help with metabolic issues, but its safety and effectiveness in humans are unclear.
research Biological activity of novel progesterone derivatives having a bulky ester side chains at C-3
The more lipophilic the progesterone derivative, the better it binds to androgen receptors and has antiandrogenic effects.
research Safety aspects of androgen treatment with 5α-dihydrotestosterone
DHT is a strong androgen that may pose less risk to the prostate compared to 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 Pharmacokinetics and Bioconversion of Dehydroepiandrosterone after Application of Dexamethasone in Women with Polycystic Ovary Syndrome

research In vitro and In vivo Effects of 17β-N-(4-phenylcarbamoyl) androst-4-en-3- one Derivatives as 5a-reductase Inhibitors on Androgen-dependent Glands
Three compounds were found to inhibit a prostate disease-related enzyme and reduce prostate size more effectively than the current treatment, suggesting they could be used for treating benign prostatic hyperplasia.
research Synthesis of novel andostane-N-cyclohexyl-17-carboxamides, and their effect on the 5α-reductase isoform 2, the androgen receptor, and androgen-dependent glands
New compounds were made and tested, with compound 6 showing potential for treating prostate-related diseases.
research Is 3α, 17β-androstanediol-glucuronide a diagnostic marker in women with androgenic manifestations?
3α, 17β-androstanediol-glucuronide is not a useful marker for androgen excess but may help monitor certain treatments.
