Research
150-180 / 1000+ resultsresearch A quantitative ultra-performance liquid chromatography high-resolution mass spectrometry analysis of steroids from human scalp hair
The method can measure multiple steroids in human hair to study long-term steroid metabolism, especially in newborns and children.
research Simultaneous quantitation of nine hydroxy-androgens and their conjugates in human serum by stable isotope dilution liquid chromatography electrospray ionization tandem mass spectrometry
A new method accurately measures nine specific hormones in human blood.
research Is Dihydrotestosterone a Classic Hormone?
Dihydrotestosterone (DHT) mainly affects nearby cells, doesn't significantly change prostate hormonal environment or cancer risk, and doesn't play a main role in causing hair loss or acne. More research is needed on its effects on heart health, sexual function, and bone health.
research THE TREATMENT OF HIRSUTISM WITH A COMBINATION OF DESOGESTREL AND ETHINYL OESTRADIOL
A combination of desogestrel and ethinyl oestradiol effectively reduces hair growth in hirsute women.
research Latest advances in oral hormonal male contraception: efficacy, mechanisms of action, and future perspectives
New male contraceptive pills show promise in reducing sperm production with mild side effects.
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 Finasteride versus cyproterone acetate-estrogen regimens in the treatment of hirsutism
Finasteride and CPA-EE2 equally reduce hirsutism, but affect hormone levels differently.
research Plasma levels of C19 steroid glucuronides in pre-menopausal women with non-classical congenital adrenal hyperplasia
Women with non-classical congenital adrenal hyperplasia have higher levels of certain steroids, which can be reduced by treatment.
research Marked Suppression of Dihydrotestosterone in Men with Benign Prostatic Hyperplasia by Dutasteride, a Dual 5α-Reductase Inhibitor
Dutasteride more effectively lowers DHT levels in men with enlarged prostates than finasteride.
research Testosterone therapy for women with low sexual desire: a position statement from the Brazilian Society of Endocrinology and Metabolism
Testosterone therapy may slightly increase sexual desire in women with HSDD but lacks broad recommendation due to safety concerns and limited approval.
research New Synthesis of Methyl 3β-Hydroxy-5-androstene-17β-carboxylate
A new method was developed to make a compound used in finasteride and epristeride with a 69% yield.
research A combined regimen of cyproterone acetate and testosterone enanthate as a potentially highly effective male contraceptive.
The combination of cyproterone acetate and testosterone enanthate is highly effective in preventing sperm production and could be a good reversible male contraceptive.
research Advances in male hormone substitution therapy
New treatments for low male hormones improved sexual function and mood but had unclear risks, especially for older men.
research Efficacy and tolerability of HDMHG0401-10 in Patients with Androgenetic Alopecia-A Randomized Double-blind Placebo-controlled Trial
HDMHG0401-10 improves hair loss in men with androgenetic alopecia and has no major side effects.
research A model for the turnover of dihydrotestosterone in the presence of the irreversible 5α-reductase inhibitors GI198745 and finasteride
Both drugs lower DHT levels, with GI198745 being more effective.
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 Analysis of hair steroid hormone concentrations at different parts of the head by liquid chromatography-tandem mass spectrometry
Hormone levels in hair vary across the head, with the highest concentration of a key hormone linked to hair loss at the top.
research Dihydrotestosterone Stimulates 5a-Reductase Activity in Pubic Skin Fibroblasts*
Dihydrotestosterone increases the activity of an enzyme in pubic skin cells that converts testosterone to dihydrotestosterone.
research Anti-Androgen Treatment of Hirsute Women: A Study on Stress Responses
The treatment reduced hair growth and testosterone in women with excess hair and had some effects on stress responses.
research Virilism and Ectopic Expression of HSD17B5 in Mature Cystic Teratoma
A woman's mature cystic teratoma caused her virilization by producing testosterone.
research Determination of dichloromethane and chloroform in Finasteride by SPME-GC
The method accurately measures dichloromethane and chloroform in finasteride.
research Inhibition of 5α-Reductase Activity in SZ95 Sebocytes and HaCaT Keratinocytes In Vitro
The substance MK386 effectively blocked testosterone conversion and reduced cell growth in certain skin cells, but inhibiting 5α-reductase alone may not greatly improve acne.
research Testosterone, Dihydrotestosterone, and Incident Cardiovascular Disease and Mortality in the Cardiovascular Health Study
