Antiandrogens and finasteride may help treat excess hair and hair loss in women.
research Altered Hormone and Bioactive Lipid Plasma Profile in Rodent Models of Polycystic Ovarian Syndrome Revealed by Targeted Mass Spectrometry
Rodent models of PCOS show some hormone changes similar to humans, but also have key differences.
research Assessment of Anti-Inflammatory Potential of Myristica fragrans Houtt upon Membrane Stabilization
Myristica fragrans shows promise as an anti-inflammatory agent.
research Is the metabolism of testosterone to 5α-dihydrotestosterone required for androgen action in the skin?
Testosterone conversion to 5α-DHT may not be essential for its effects on the skin.

Citrullus colocynthis is a valuable natural option for medicine and pest control.
research Biotransformation of Finasteride by Ocimum sanctum L., and tyrosinase inhibitory activity of transformed metabolites: Experimental and computational insights
Fermentation of Finasteride with Ocimum sanctum L. creates new metabolite that inhibits tyrosinase.
research Direct quantitative digital autoradiography of testosterone metabolites in the pilosebaceous unit: an environmentally advantageous trace radioactive technology
The method accurately measures testosterone metabolites with high sensitivity and low environmental impact.
research Hair-Based Assessment of Sex Steroid Hormones in Patients with Anorexia Nervosa
Hair analysis shows low progesterone in anorexia patients, unchanged by short-term weight gain.
research Preliminary pharmacokinetics and metabolism of novel non-steroidal antiandrogens in the rat: Relation of their systemic activity to the formation of a common metabolite
Two non-steroidal antiandrogens, RU 58841 and RU 56187, form a common metabolite at different rates, which may influence their effects; RU 56187 could be used for prostate cancer treatment and RU 58841 for acne treatment.
research Progesterone-induced stimulation of mammary tumorigenesis is due to the progesterone metabolite, 5α-dihydroprogesterone (5αP) and can be suppressed by the 5α-reductase inhibitor, finasteride
Progesterone byproduct 5αP stimulates mammary tumor growth, but finasteride can suppress it.
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 Allopregnanolone promotes proliferation and differential gene expression in human glioblastoma cells
Allopregnanolone increases growth and changes gene activity in human brain cancer cells.
research Steroid 5α-Reductase as a Novel Therapeutic Target for Schizophrenia and Other Neuropsychiatric Disorders
S5αR inhibitors might help treat schizophrenia and other mental disorders but need more research.
research Steroid 5α-Reductase Inhibitors
New steroidal compounds could be effective for treating conditions related to 5α-reductase enzyme activity.
research Divergent neuroactive steroid responses to stress and ethanol in rat and mouse strains: relevance for human studies
Stress and alcohol affect brain chemicals differently in rats, mice, and humans, influenced by genetic differences.
research Effects of Subchronic Finasteride Treatment and Withdrawal on Neuroactive Steroid Levels and Their Receptors in the Male Rat Brain
Finasteride treatment changes brain steroid levels and receptors, affecting brain function even after stopping treatment.
research Early postnatal neuroactive steroid manipulation differentially affects recognition memory and passive avoidance performance in male rats
Changing neuroactive steroids in baby male rats affects their memory and learning differently as they grow up.
research 5α-Reductase inhibitors alter steroid metabolism and may contribute to insulin resistance, diabetes, metabolic syndrome and vascular disease: a medical hypothesis
Some hair loss and prostate drugs might increase the risk of diabetes and heart disease.
research 3,3-Diphenylpentane skeleton as a steroid skeleton substitute: Novel inhibitors of human 5α-reductase 1
A new compound effectively inhibits human 5α-reductase 1.
