title: Plasma testosterone and beta HCG levels in the first twenty-four hours of life in neonates with cryptorchidism.
abstract: We determined serum concentrations of beta HCG and testosterone by specific radioimmunoassays in eight cryptorchid and 13 normal newborns in the first 24 h of life. Mean serum beta HCG concentration in the cryptorchid infants (18.9 +/- 9.7 miu/ml) did not differ significantly from the control group (26.7 +/- 7.6 miu/ml). Mean serum testosterone level in the cryptorchid newborns (271 +/- 27 ng/dl) also did not differ significantly from the control group (333 +/- 30 ng/dl). These data suggest beta HCG and testosterone concentrations on the first day of life are of the same magnitude in normal and cryptorchid infants.
