A paper published today in Biology of Reproduction's Papers-in-Press describes the effects of brief prenatal exposure to plant estrogens on the mouse oviduct, modeling the effects of soy-based baby formula on human infants. The results suggest that exposure to estrogenic chemicals in the womb or during childhood has the potential to affect a woman's fertility as an adult, possibly providing the mechanistic basis for some cases of unexplained female infertility.
