title: Sexual receptivity of adult female rats prenatally intoxicated with alcohol on gestational day 8.
abstract: On gestational day 8 (GD 8), pregnant albino rats received two IP injections, spaced by 4 hours, of either ethanol (2.9 g/kg in 24% v/v saline solution) or saline. Adult females exposed to ethanol in utero showed greater sensitivity to estrogen, but not to estrogen plus progesterone, for induction of lordotic response. The 5-HT1 receptor agonist 5-methoxy-N,N-dimethyl-tryptamine (5-MeODMT) had a significantly smaller effect in inhibiting lordosis response in experimental rats. The greater sensitivity to estrogen and lower sensitivity to the receptor agonist could be a consequence of long-term changes in central neurotransmitter systems induced by acute intoxication with ethanol on GD 8.
