[253] [254] [255] Progestogens with the potential for clinically relevant glucocorticoid effects include the 17α-hydroxyprogesterone derivatives chlormadinone acetate, cyproterone acetate, medroxyprogesterone acetate, megestrol acetate, promegestone, and segesterone acetate and the testosterone derivatives desogestrel, etonogestrel, and gestodene.
Cyproterone acetate (CPA), sold alone under the brand name Androcur or with ethinylestradiol under the brand names Diane or Diane-35 among others, is an antiandrogen and progestin medication used in the treatment of androgen-dependent conditions such as acne, excessive body hair growth, early puberty, and prostate cancer, as a component of feminizing hormone therapy for transgender individuals ...
[84] [85] [7] [8] Aside from cyproterone acetate and chlormadinone acetate, a few other progestins used in oral contraceptives and/or in menopausal HRT including dienogest, drospirenone, medrogestone, nomegestrol acetate, promegestone, and trimegestone also have varying degrees of AR antagonistic activity.

Testosterone levels with 2, 5, or 10 mg/day dienogest, 10 mg/day oral cyproterone acetate, or placebo in healthy young men. [37] Dienogest has been found to suppress testosterone levels in men by 43% at 2 mg/day, 70% at 5 mg/day, and 81% at 10 mg/day.
Testosterone levels with 100 to 300 mg/day oral cyproterone acetate and low-dose oral estrogen in men. [160] The estrogen used was 0.1 mg/day diethylstilbestrol (DES), [160] which has been described as an "extremely low" dosage. [87] Levels of testosterone were decreased by about 95% with the combination and by about 61% with cyproterone ...
Cyproterone, also known by its developmental code name SH-80881, is a steroidal antiandrogen which was studied in the 1960s and 1970s but was never introduced for medical use. [ 1 ] [ 2 ] [ 3 ] It is a precursor of cyproterone acetate (CPA), an antiandrogen, progestin , and antigonadotropin which was introduced instead of cyproterone and is ...
15β-Hydroxycyproterone acetate (15β-OH-CPA) is a steroidal antiandrogen and the major metabolite of cyproterone acetate (CPA). [1] [2] [3] It is formed from CPA in the liver by hydroxylation via the cytochrome P450 enzyme CYP3A4. [1] [2] [3] During therapy with CPA, 15β-OH-CPA circulates at concentrations that are approximately twice those ...
