Intake of protein-rich foods in relation to outcomes of infertility treatment with assisted reproductive technologies.

Background: Some dietary factors have been linked to outcomes of infertility treatment with assisted reproductive technology (ART), but the role of intake of meats and other protein-rich foods remains unclear.

Objective: The aim of this manuscript was to study the relation between preconception intake of meat and other protein-rich foods and outcomes of infertility treatment with ART.

Design: A total of 351 women enrolled in a prospective cohort at the Massachusetts General Hospital Fertility Center and underwent 598 ART cycles for infertility treatment.

Discrete survival model analysis of a couple's smoking pattern and outcomes of assisted reproduction.

Background: Cigarette smoking has been associated with worse infertility treatment outcomes, yet some studies have found null or inconsistent results.

Methods: We followed 225 couples who underwent 354 fresh non-donor assisted reproductive technology (ART) cycles between 2006 and 2014. Smoking history was self-reported at study entry.

Soy food intake and treatment outcomes of women undergoing assisted reproductive technology.

Objective: To study the relation of dietary phytoestrogens intake and clinical outcomes of women undergoing infertility treatment with the use of assisted reproductive technology (ART).

Design: Prospective cohort study.

Setting: Fertility center.
