Abstract
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.
Patient(s):
A total of 315 women who collectively underwent 520 ART cycles from 2007 to 2013.
Intervention(s):
None.
Main Outcome Measure(s):
Implantation, clinical pregnancy, and live birth rates per initiated cycle.
Result(s):
Soy isoflavones intake was positively related to live birth rates in ART. Compared with women who did not consume soy isoflavones, the multivariable-adjusted odds ratios of live birth (95% confidence interval) for women in increasing categories of soy isoflavones intake were 1.32 (0.76–2.27) for women consuming 0.54–2.63 mg/d, 1.87 (1.12–3.14) for women consuming 2.64–7.55 mg/d, and 1.77 (1.03–3.03) for women consuming 7.56–27.89 mg/d.
Conclusion(s):
Dietary soy intake was positively related to the probability of having a live birth during infertility treatment with ART.
