title: [Androgenic function of the testes and gonadotropic activity of the pituitary gland in various forms of cryptorchism in children and adolescents].
abstract: Biochemical and radioimmunoassay of testosterone content in the blood and urine, epitestosterone and 17-CS level in the urine of 80 boys has shown, that the ovarian androgenic function is reduced in all the forms of cryptorchidism. The potential testis reserves are progressively lowered with the age in patients with bilateral and false retention and remain unchanged in unilateral cryptorchidism. In the absolute majority of patients the change in gonadotropic hormone production is noted, manifesting in the decreased and/or increased LH and FSH content in the blood of different patients, that is seemed to reflect heterogeneity of cryptorchidism pathogenetic forms. The ovarian testosterone production rise after chorionic gonadotropin injection did not inhibit the hypophyseal FSH activity.
