It is described to which extent the fertility potential in the following six groups of patients living in sterile marriages is lowered: in 298 patients with Klinefelter's syndrome, 38 hypogonadotropic eunuchoids, 216 bilateral and 258 unilateral cryptorchids, in 500 men with testicular hypoplasia in whom the long axis of both testicles had always been shorter than 34 mm, and in 109 men with a varicocele.
