A histopathologic study of the effects of gossypol on the female rat.
The purpose of this study was to examine the tissues of female rats treated with gossypol acetic acid for morphologic evidence of an underlying mechanism of infertility. The number of estrous cycles, and body and adrenal weights were also compared. The number of estrous cycles decreased in rats treated with 60 mg/kg gossypol acetic acid for 30 days. Body weights were also reduced in rats treated with 40 mg or 60 mg/kg per day for 30 days when compared to controls. However, no significant differences were found in any group when comparing adrenal weights, adrenal weight/body weight ratios or adrenal histology. The body weight loss was related, at least in part, to diarrhea and dehydration in eight of the treated animals. It is interesting that though the gossypol-treated rats had reduced numbers of estrous cycles, no histopathologic changes were found in their ovaries, uterus or vagina.
