title: Effects of experimental bilateral cryptorchidism and castration on the plasma gonadotropins in male rats during sexual maturation.
abstract: The effect of bilateral cryptorchidism and castration on serum LH and FSH was assessed in rats throughout their sexual maturation. After short time (4 days) castration marked elevations of FSH and increases of LH in plasma are recorded in all developmental stages. Bilateral cryptorchidism caused after 4 days in different age groups elevations of LH regardless of the sexual maturation. FSH was elevated in these cryptorchid animals only in more mature animals.
