"Protein intake and ovulatory infertility," Chavarro JE, Willett WC, et al, (Address: Department of Nutrition, Harvard School of Public Health, Boston, MA 02115, USA. E-mail: jchavarr@hsph.harvard.edu ). Summary: In a study involving 18,555 married women without a history of infertility, results indicate that higher intake of protein from vegetable sources instead of animal sources may lower the risk of ovulatory infertility. During 8 years of follow up, 438 women reported ovulatory infertility. After adjusting for potential confounders, the highest quintile for animal protein intake was associated with a 39% increased risk of ovulatory infertility, compared with the lowest quintile. On the other hand, the highest quintile for vegetable protein intake was associated with a 22% reduced risk of ovulatory infertility, compared with the lowest quintile. Additionally, substituting animal protein with vegetable protein for 5% of total energy intake was associated with a 50% reduced risk of ovulatory infertility. Thus, the authors of this study conclude, "Replacing animal sources of protein with vegetable sources of protein may reduce ovulatory infertility risk." Am J Obstet Gynecol, 2008; 198(2): 210.e1-7.
