Gonadal function was studied for forty-three cases with history of surgery to cryptorchidism and five normal pubertal boys. Methods of surgery for cryptorchidism were: bilateral orchiopexy (13 cases), unilateral orchiopexy (25 cases) and unilateral orchiectomy for unilateral cryptorchidism (5 cases). Ages were from prebubertal to postpubertal. Pubertal maturations for external genitalia (G1〜G5) and pubic hair (PH1〜PH5) by Tanner were correlated with chronological and bone ages. Plasma LH and FSH and responses to LH-RH (intraveneonsly 100μg) and plasma testosterone (T.) and responses to HCG (4th day after HCG, intramuscular 10,000 units) were increased in most cases with chronological age and pubertal maturations. In bilateral orchiopexy plasma LH and FSH and LH response to LH-RH were hlgher than unilateral orchiopexy (P<0.02, P<0.05, P<0.05). Plasma T. and response to HCG were not different according to methods of surgery and retained positions. One after bilateral orchiopexy showed low response of plasma LH and plasma T. in spite of pubertal age. All cases of bilateral orchiopexy (n=4) were azoospermia and two of unilateral orchiopexy (n=6) were oligospermia.
