Beta-endorphin in normozoospermic and pathologic human semen.

R Singer, S Bruchis, M Barnet, M Sagiv, H Kaufman, C Servadio.

Abstract

beta-Endorphin was estimated in normozoospermic, oligozoospermic and azoospermic human semen. The mean amount in normozoospermic specimens was 278.6 +/- 43.6 (SE) pg/ml while in the others only 191.1 +/- 25 pg/ml. Both values are significantly higher than those present in the blood.
