research Clinical biochemistry of dihydrotestosterone
Understanding how DHT works is important for diagnosing and treating hormone-related disorders.
research Finasteride blocks progesterone synthesis in MA-10 Leydig tumor cells
research An improved synthesis of finasteride from 4-androsten-3,17-dione
The new method makes finasteride cheaper and easier to produce.
research In vitro [7-3H]-testosterone metabolism by the rat ventral prostate—Effect of some exogenous compounds
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 Hydroxylation of dehydroepiandrosterone in human scalp hair folhcles
The enzyme system in hair follicles is similar to the liver's and is affected by certain inhibitors.
research The Androgen Receptor and Its Use in Biological Assays: Looking Toward Effect-Based Testing and Its Applications
Scientists have developed a new method to detect steroid abuse in athletes using cell-based tests, which could be the future of anti-doping methods.
research Daily subcutaneous testosterone for management of testosterone deficiency
Daily subcutaneous testosterone effectively restores testosterone levels in men.
research Anabolic-Androgenic Steroids and Cardiometabolic Derangements
Long-term anabolic steroid use can lead to heart and metabolic health issues.
research The safety of 52 weeks of oral DHEA therapy for postmenopausal women
Taking DHEA for a year is generally safe for postmenopausal women but may cause acne and more facial hair without improving metabolism or aging.
research Effects of Dehydroepiandrosterone Therapy on Pubic Hair Growth and Psychological Well-Being in Adolescent Girls and Young Women with Central Adrenal Insufficiency: A Double-Blind, Randomized, Placebo-Controlled Phase III Trial
DHEA treatment helps grow pubic hair and boosts mood in girls with adrenal issues.
research Development of a new gas chromatography–mass spectrometry (GC–MS) methodology for the evaluation of 5α-reductase activity
A new method was developed to accurately measure enzyme activity related to prostate health.
research Adrenal steroid precursors exert potent androgenic action in the hamster sebaceous glands of flank organs and ears.
Certain adrenal hormones can strongly stimulate oil gland growth in hamster skin, similar to male hormones.
research Effects of Dehydroepiandrosterone Therapy on Pubic Hair Growth and Psychological Well-Being in Adolescent Girls and Young Women with Central Adrenal Insufficiency: A Double-Blind, Randomised, Placebo-Controlled Phase III Trial
DHEA therapy improves pubic hair growth and psychological well-being in girls with central adrenal insufficiency.
research The use of anabolic androgenic steroids: A focus on polypharmacy
Using high doses and multiple drugs with steroids is risky and should be prevented.
research Pharmacology of antiandrogens
Antiandrogens affect androgen-dependent body functions and are used for various medical conditions, with some risks like fetus feminization, but new forms like 17α-propylmesterolone show promise for acne without systemic effects.
research Steady-state pharmacokinetics of oral testosterone undecanoate with concomitant inhibition of 5α-reductase by finasteride
Finasteride doesn't affect oral testosterone undecanoate, and high DHT levels may cause acne, prostate issues, and hair loss.
research Design, Synthesis, and Biological Characterization of Metabolically Stable Selective Androgen Receptor Modulators
Researchers developed new compounds that target the androgen receptor effectively with fewer side effects.
research Effects of Dehydroepiandrosterone Therapy on Pubic Hair Growth and Psychological Well-Being in Adolescent Girls and Young Women with Central Adrenal Insufficiency: A Double-Blind, Randomized, Placebo-Controlled Phase III Trial
DHEA therapy improves pubic hair growth and psychological well-being in young females with central adrenal insufficiency.

research Steroidomics for highlighting novel serum biomarkers of testosterone doping
Monitoring steroid hormones in blood can better detect testosterone doping.
research Dehydroepiandrosterone for women in the peri- or postmenopausal phase
DHEA may help with sexual function when used intravaginally by menopausal women but is similar to hormone therapy in other aspects and might cause more side effects like acne and hair loss.
research Sex hormones and sarcopenia in older persons
Sex hormone treatments can increase muscle mass in older adults but have inconsistent effects on muscle function and may carry cardiovascular risks.
research MK-386, an Inhibitor of 5α-Reductase Type 1, Reduces Dihydrotestosterone Concentrations in Serum and Sebum without Affecting Dihydrotestosterone Concentrations in Semen1

PM-9 and finasteride effectively inhibit the enzyme that converts testosterone to DHT.
research Mechanisms of testosterone action
Testosterone works in different ways, including direct interaction with its receptor, conversion to other hormones for specific effects on genitalia, hair, bones, and muscle, and changes in body fat and sexual function when low.
