title: Soy food intake and treatment outcomes of women undergoing assisted reproductive technology.
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).
  
  
  METHODS
  Prospective cohort study.
  
  
  METHODS
  Fertility center.
  
  
  METHODS
  A total of 315 women who collectively underwent 520 ART cycles from 2007 to 2013.
  
  
  METHODS
  None.
  
  
  METHODS
  Implantation, clinical pregnancy, and live birth rates per initiated cycle.
  
  
  RESULTS
  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.
  
  
  CONCLUSIONS
  Dietary soy intake was positively related to the probability of having a live birth during infertility treatment with ART.
