Abstract
Exogenous gonadal hormones differentially affected the adult mating behavior of intact or castrated male, female, and pseudohermaphroditic female guinea pigs. Pseudohermaphrodites were offspring of females injected daily with testosterone propionate from the 10th day of preg?nancy to parturition. The baseline rate of mounting was highest for intact males, with pseudohermaphrodites and castrated males showing an equal rate higher than the remaining 3 groups. Daily injections of testosterone propionate elevated the mounting rate for castrated males and spayed pseudohermaphrodites to the level of normal males. Effect of estradiol benzoate on the groups mating behavior was either negligible or transitory. Results were interpreted as supporting the hypothesis that prenatal androgen permanently modifies structures integrating mating behavior.Keywords
