The presence of ethanol in the oviductal and uterine luminal fluids of alcoholized rats.

Blood ethanol level and the presence of ethanol in the oviductal and uterine luminal fluids were determined in female albino rats (Wistar strain) following chronic alcoholization by 20% ethanol offered ad libitum in drinking water during a period of 40-50 and 90-100 days, respectively. Ethanol was found both in the oviductal and in the uterine luminal fluids in lower concentrations as compared with the blood ethanol level. The findings presented suggest the possible direct noxious action of ethanol upon preimplantation development (effects detected in previous investigations). Problems raised by present results are discussed.
