Abstract

The causes of infertility in 504 men were studied prospectively. The major causes were varicocele (28.8%), infection (20.8%), bilateral testicular failure (15%), idiopathic oligospermia (6.6%), multifactorial (5.6%), cryptorchidism (4%), sexual problems (3.8%) and surgical injury (1.6%). Unilateral testicular torsion and sickle cell disease though of less frequent occurrence were of particular interest because their roles are only now beginning to be realized. Gonadotrophin deficiency was an insignificant cause of subfertility.

In spite of the high incidence of infection and past history of urethritisNeisseria gonorrheae was surprisingly not isolated from any patient.

Compared with Caucasian studies, the high incidence of infection, and the low incidence of gonadotrophin deficiency are major points of difference.
