[Luteinizing hormone secretion in cryptorchism and anorchism]

The plasma LH content was studied in 22 patients aged 1 to 16 years, suffering from cryptorchidism and anorchism, by radioimmunoassay. The gonad androgenic function was evaluated according to the plasma testosterone level under conditions of the functional test with chorionic gonadotrophin. Considerable polymorphism in the gonad function change was found: in 45.4% of patients with cryptorchidism LH secretion was elevated, in 31.8% reduced, in 22.7% it did not differ from the age norm. In 56.2% of patients with anorchism, OH secretion was heightened, in 18.8% decreased, in 25 it did not deviate from the age norm. The LH level increase was recorded in prepuberal age and in anorchism it was pronounced to a greater degree. Correlation between LH and gonad function revealed under conditions of the test with chorionic gonadotrophin, was noted in cryptorchidism.
