Male Repro Flashcards
Testosterone production
95% leydig, 5% adrenals
Dihydrotestosterone
Potent androgen created from testosterone by 5 alpha reductase. responsible for prostate development
Methyl testosterone
Testosterone analog, orally effective used for testosterone hormone replacement.
Oxandrolone
dihydrotestosterone derivative, orally active, cannot be converted by aromatase into estrogens, promotes muscle growth (anabolic steroid)
Androgen therapy AE
epiphyseal plate closure, due to conversion to estrogens at growth plates. priapism, hepatic carcinoma, hypogonadism, aggression, urinary obstruction, baldness, gynecomastia, shrunken testes, abnormal hair growth
Cyproterone acetate
androgen antagonist used to reduce sexual drive in men and treat hirsuitism in women.
