Incidence of hypospadia and epispadia in chromatin-positive men

There are described some results of examination of three patients with a Klinefelter's syndrome two of whom had a heavy form of hypospadia, and one suffered from epispadia. The disturbances of penis development are explained, with respect to findings in adult age, by the insensibility of target tissues to the effect of testicular androgen. This insensibility was already acting in the third month of intrauterine life of the fetus.
