Effects of estrogen-like plant compounds on the vaginal epithelium pituitary, adrenal glands, and uterus of rats.

IMPACT STATEMENT: The results of this work provide preliminary evidence that ovariectomized rats display the vaginal smear cells typical of the estrous phase of mature rats after long-term ingestion of Colocasia esculenta flavonoid glycosides. Moreover, the treatment caused beneficial effects on endocrine and reproductive organs compared to estradiol. The animals did not exhibit significant body weight alterations among the groups, demonstrating the maintenance of standard metabolism and energy balance. The overall findings obtained with the rat model of menopause highlight the importance of dietary consumption of C. esculenta constituents as potential selective estrogen receptor modulators and suggest that they may prevent some of the metabolic disorders related to estrogen deficiency.
