research Studies on Neurosteroids XXV: Influence of a 5α-Reductase Inhibitor, Finasteride, on Rat Brain Neurosteroid Levels and Metabolism
Finasteride almost fully depletes allopregnanolone in rat brains and enhances 20α-DHP, but doesn't change 3α-DHP levels.
research Increased Androgen Binding Capacity in Sebaceous Glands in Scalp of Male-Pattern Baldness
Men with male-pattern baldness have more androgen receptors in their scalp's oil glands, which may contribute to hair loss.
research Treatment of Hyperandrogenism in Women
Cyproterone acetate is the preferred treatment for women's hyperandrogenism when estrogen/progestogen use is safe.
research 5α-Metabolism in Finasteride-Treated Subjects and Male Pseudohermaphrodites with Inherited 5α-Reductase Deficiency

research GABRA2 Alleles Moderate the Subjective Effects of Alcohol, Which Are Attenuated by Finasteride
GABRA2 gene variations impact alcohol response, and hair loss medication finasteride reduces some effects.
research A Randomized Trial of Oral DHEA Treatment for Sexual Function, Well-Being, and Menopausal Symptoms in Postmenopausal Women with Low Libido
DHEA did not improve sexual function, well-being, or menopausal symptoms in postmenopausal women with low libido but caused side effects like acne and increased facial hair.
research 5α-Reductase Inhibitors: Progress and Therapeutic Potential
5α-reductase inhibitors help treat disorders caused by DHT and have potential for future therapies.
research Xenobiotic-Metabolizing Enzymes in the Skin of Rat, Mouse, Pig, Guinea Pig, Man, and in Human Skin Models
