High consumption of proteins of plant origin may diminish the risk of developing ovulatory infertility.

This study examined the association between the consumption of proteins from plant and animal sources and the incidence of ovulatory infertility. Researchers examined the diets of 18,555 married women who were without any history of infertility and planning to get pregnant for 8 years. The relative risk of ovulatory infertility in all the subjects were also assessed.

Researchers observed a lower incidence of ovulatory infertility in subjects who obtained their proteins from plant sources than in those who frequently consumed animal proteins. A 50% reduction in the risk of ovulatory infertility was found in subjects who obtained 5% of their energy needs from vegetable proteins in this study. The findings of this research work reveal that substituting animal proteins with plant proteins in a diet could lower the risk of developing ovulatory infertility in women within childbearing age.
