Effects of chronic low-dose ethanol intake on sexual behavior in rats.
The effects of 8-week ethanol intake (3% v/v in drinking water) on the sexual activity of male rats were investigated during three experimental sessions with 15-day intersession intervals. Chronic ethanol consumption did not significantly influence any copulatory parameter during the three experimental sessions. The evaluation of ultrasonic emission during sexual behavior showed that rats treated with ethanol exhibited a significant increase of the postejaculatory vocalization length during the third test session. These results indicate that the chronic intake of low doses of ethanol, which does not induce either tolerance or dependence, only slightly affects the motivational state of male rats during sexual activity.
