Serum levels of LH and FSH were determined before and at 10 intervals from 10 minutes to 8 1 2M hours after coitus in 8 men and 5 women. The women were studied between day 8 and 12 of their menstrual cycles. Gonadotropin concentrations did not differ from control means at any interval after sexual intercourse and are therefore, under these circumstances, independent of sexual activity. Testosterone concentrations in men were also unaffected by coitus. In addition, concentrations of LH, FSH, and testosterone during a 2 month interval of sexual abstinence were not different than during periods of intercourse 2 or 3 times a week.
