OBJECTIVE: The objective of the study was to evaluate whether intake of protein from animal and vegetable origin is associated with ovulatory infertility.
STUDY DESIGN: A total of 18,555 married women without a history of infertility were followed up as they attempted a pregnancy or became pregnant during an 8 year period. Dietary assessments were related to the incidence of ovulatory infertility.
CONCLUSION: Replacing animal sources of protein with vegetable sources of protein may reduce ovulatory infertility risk.
