Plasma testosterone and βHCG levels in the first twently-four hours of life in neonates with cryptorchidism

We determined serum concentrations of HCG and testosterone by specific radioimmunoassays in eight cryptorchid and 13 normal newborns in the first 24h of life.Mean serum 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 that HCG and testosterone concentrations on the first day of life are of the same magnitude in normal and cryptorchid infants.
