Radioimmunoassays of Ethinyl-norgestrienone (R-2323) and medroxyprogesterone acetate (MPA) and their clinical applicability


Radioimmunoassays for 2 synthetic progestins (Ethinyl-norgestrienone, R 2323 and medroxyprogesterone acetate, MPA) are demonstrated. 10 patients aged 31 to 72 years were treated with ethinyl-norgestrienone with different schedules and 3 men suffering from benign prostatic hypertrophy were treated with medroxyprogesterone acetate. Plasma levels of testosterone, LH, FSH were monitored before, during and after treatment.
