Plasma testosterone response at 1st and 4th day after short- and long-term hCG stimulation test

Human chorionic gonadotropin (hCG) stimulation test is a reliable dynamic test for the evaluation of testicular function during childhood. Several protocols have been recommended but their reliability is controversial. In order to decide the best timing to measure stimulated testosterone leve...

description Human chorionic gonadotropin (hCG) stimulation test is a reliable dynamic test for the evaluation of testicular function during childhood. Several protocols have been recommended but their reliability is controversial. In order to decide the best timing to measure stimulated testosterone levels in short- and long-term hCG protocols, we evaluated 83 prepubertal patients in two group. In group A, 34 patients with isolated micropenis and in group B, 49 inguinal cryptorchidic patients were enrolled. In group A short-term hCG protocol (3000 IU/m2/im/3 days) and in group B long-term hCG protocol (1500 IU/m2/im; thrice a week for 3 weeks) was administered. Blood samples were drawn at the initiation of the test and then at the 1st and 4th days after the last hCG injection. Each case's peak stimulated testosterone (Tmax) and the incremenet in plasma testosterone (deltaT) were calculated and compared with the 1st and 4th day responses within the group. In the short-term protocol the 4th day responses were higher than the 1st day responses (p
