Abstract

Adult sexual behaviors were characterized in male rats prenatally exposed to ethanol, stress, or ethanol combined with stress; 60% to 75% of each group exhibited female-typical lordosis. A substantial proportion of males subjected to alcohol (44%) or to alcohol with stress (54%)failed to ejaculate. The adult genitalia and testicular size appearednormal in all groups. Either alcohol or stress can suppress fetal plasma testosterone. Thus, exposing pregnant dams to alcohol, particularly in association with stress, may alter the hormonal milieu of their male fetuses sufficiently to block full masculinization and defeminization of sexually dimorphic copulatory behavior potentials, but not anatomy. It appears that certain pharmacological and stressful factors caninteract during fetal ontogeny to influence the process of sexual behavior differentiation.
