Androgens regulate 5 alpha-reductase activity in hamster sebaceous glands.
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 Anabolic effect of dihydrotestosterone in testicular feminization syndrome
Dihydrotestosterone has a reduced effect on muscle-building in people with testicular feminization syndrome, especially after their gonads are removed.
research Pharmacokinetics of a transdermal testosterone cream in healthy postmenopausal women
A 5 mg dose of transdermal testosterone cream effectively restores testosterone levels in postmenopausal women.
research TESTOSTERONE-INDUCED ANDROGENETIC ALOPECIA MICE MODEL: A PRELIMINARY STUDY
A testosterone-induced hair loss model in mice was successfully created for future research and treatment testing.
research Changes of androgens levels in menopausal women
Menopausal women have higher androgen levels, which can cause symptoms like facial hair growth and low sexual desire.
research Low serum testosterone is associated with an increased risk of first-time renal calculi in men without testosterone replacement therapy
Low testosterone increases kidney stone risk in men not on testosterone therapy.
research New Insights into Testosterone Biosynthesis: Novel Observations from HSD17B3 Deficient Mice
Mice without the enzyme HSD17B3 still produce normal testosterone, suggesting they have different ways to make it compared to humans.

research The Serum Evaluation of Sex Hormones Including DHEAs, DHT, Testosterone in Oral Lichen Planus Patients
Oral lichen planus is not linked to sex hormone levels.
research Sex steroid levels in corresponding cerebrospinal fluid and serum samples quantified by mass spectrometry in men

research Serum androgens and risk of atrial fibrillation in older men: The Cardiovascular Health Study
Older men with low levels of a testosterone byproduct had a higher chance of developing an irregular heartbeat.
research Androgens in postmenopausal women
Testosterone in older women can increase bone density, muscle mass, fat mass, improve memory, and boost libido, but may cause nipple color changes.
