Sexual development and activity of men with disturbances of somatic development.

By means of Questionnaires HTDM and SAM the heterosexual development and sexual activity were investigated in the following groups of males: 1. the control group consists of 345 married men from sterile marriages, who were adequately developed somatosexually, had normozoospermia in the ejaculate and a good potency; 2. in 48 unilateral and 57 bilateral adult cryptorchids; 3. in 101 married men with a distinct testicular hypoplasia, the long axis of both sexual glands being shorter than 30 mm; 4. in 110 patients with a Klinefelter's syndrome; 5. in 14 patients with hypogonadotropic hypogonadism. Whereas the retardation of heterosexual development was found only in two groups (group 4 and 5), a distinctly lowered activity in sex life was ascertained in all four pathological samples.
