We assessed the effects of dietary consumption of soy isoflavone aglycones on the reproductive tract of sexually mature male and female mice. Isoflavone concentrates with a ratio of 10:1, 2:1 or 1:10 genistein:daidzein (G:D) were added to provide 120 mg total isoflavones/1800 Calories (approximately 40 mg/kg body weight) to diets having either casein/lactalbumin or soy protein isolate as the source of protein. After 16 weeks, mice were necropsied and gross and histopathologic assessments of uterus, vagina, testes and accessory sex glands were completed. Effects of the 10G:1D isoflavone concentrates were absent or minimal in females but in males included atrophy of accessory sex glands. In contrast, the 2G:1D and 1G:10D concentrates caused dramatic estrogenic effects in both male and female mice. Effects in females included endometritis and effects typical of estrogenic stimulation (i.e., uterine enlargement, keratinization of vaginal epithelium, increased height of endometrial surface epithelial cells, and uterine squamous metaplasia). Effects in males included reduced plasma testosterone concentrations, atrophy of seminiferous epithelium, atrophy of accessory sex glands, and squamous metaplasia of seminal vesicles. Some effects varied with protein source. We conclude that a diet containing approximately 40 mg/kg soy isoflavone aglycones with a genistein:daidzein ratio of 2:1 or less has marked estrogenic effects on the reproductive system of male and female mice.
