If you’re pregnant or thinking of having a baby, you might want to take a look at some new research on the effects of plant estrogens, such as that found in soy, on a developing fetus. According to Medical News Today, a paper published in Biology of Reproduction’s Papers-in-Press suggests that exposure to estrogenic chemicals in the womb or during childhood has the potential to negatively affect a woman’s fertility as an adult.
This coincides with earlier research on neonatal effects of exposure to plant or environmental estrogens. In studies with mice, researchers found that causes of infertility included failure to ovulate, reduced ability of the oviduct to support embryo development before ovulation, and failure of the uterus to support effective implantation of blastocyst-stage embryos.
Since human development of the reproductive tract continues through puberty, researchers believe that estrogenic chemical exposure to human females as fetus, infant, child, and adolescent could have impacts on their fertility. The authors suggested that minimizing the use of soy-based baby formula would be a step toward maintaining female reproductive health.
