Abstract
- From October 1981 to August 1982, a program of plasma gonadotropin (FSH & LH) and testosterone measurement was undertaken in 33 cases of prepubertal cryptorchid boys. Radioimmunoassay resulted in the following findings. 1. The mean values of each FSH, LH and testosterone in unilateral prepubertal cryptorchid boys did not show a correlation with chronologic age. 2. There were no differences in the value of FSH and LH between unilateral cryptorchid boys and Canadian healthy boys, except for a decrement in cryptorchid boys in age group from 6 to 8 and from 8 to 10. No differences in the values of testosterone through the whole age group were observed. It seems to be indicated that the study of histopathology of the testis and of pituitary hormones especially via the stimulation test is helpful for further evaluation of pathogenesis of cryptorchidism in hormonal approach.
