Human chorionic gonadotropin in the treatment of the infertile man

We have treated 128 men with proved infertility with human chorionic gonadotropin. Excellent results were obtained in the patients who underwent varicocelectomy but who did not respond to the operation. Good results were obtained in the idiopathic oligospermic men, that is with sperm density less than 20 million. Indeterminate results were obtained in patients with sperm values more than 20 million. However, therapy was deemed inappropriate in those patients who either had elevation of follicle-stimulating hormone, an untreated varicocele or biopsy findings of hyalinization, or atrophy, which would preclude success of therapy.
