The effect of androgen and different progestins on spermatogenesis was studied in young men with subfertility, prostatovesiculitis and haematospermia, and in older men with benign hypertrophy of the prostate. The compounds (testosterone, testosterone oenanthate, ethinyl oestradiol, megestrol acetate, ethinyl norgestrienone and Depo-Provera) were administered intramuscularly, orally or as subcutaneous silastic implants.
