The effect of intravenously administered human chorionic gonadotrophin on plasma testosterone in patients with sexual impotence and oligozoospermia.
The intravenous administration of human chorionic gonadotrophin (hCG) leads to a significant increase of plasma testosterone in normal men after two h (from 5.85 to 8.35 ng/ml). The rise of plasma testostosterone occurs also in men with idiopathic oligozoospermia (5.81 to 6.84 ng/ml) but it is absent in men with sexual impotence (5.30 resp. 5.37 ng/ml). These data refer to men aged between 20 and 30 years. It is concluded, that the response to hCG may be of diagnostic help in sexual impotence and in oligozoospermia, especially in respect to a therapeutic approach.
