Abstract

OBJECTIVE:

The antispermatogenic and contraceptive importance of gossypol had been established in male animals, including man; in the present work, adult female Wistar rats weighing 110 - 160g were used to study the effect of cottonseed oil (gossypol) on oestrous cycle and ovulation.

MATERIALS AND METHODS:

Forty-five cyclic female rats were sorted randomly into three experimental groups of fifteen animals each. Oral doses of 20 and 40 mg/kg/body weight were administered once a day at 0900 hr for a period of 15 days. Vaginal swab of animals were taken each day between 0700 hr- 0900 hr to study their oestrous cycle; at the end of each cycle (4-5 days), a batch of 5 animals was sacrificed in each group to evaluate the number of ova shed.

RESULTS:

The results showed that gossypol had no disruptive effects on oestrous cycle; ovulation was not adversely affected, neither was there any significant reduction (p > 0.05) in the number of oocytes released.

CONCLUSION:

Because gossypol did not alter the oestrous cycle and ovulation patterns in the study animals, we suggest that certain factors exist in female animals that abolish or limit gossypol toxicity; these were extensively discussed.
