The impact of preconceptual diet on the outcome of reproductive treatments.

PURPOSE OF REVIEW

To discuss the dietary factors that influence the reproductive outcomes in patients undergoing fertility treatment.

RECENT FINDINGS

Recent studies have found that a woman's nutritional status and dietary intake can play a role in her reproductive health. In addition to weight, specific dietary patterns rich in omega-3 fatty acids and micronutrients such as vitamin D have all been shown to impact fertility. Although data regarding diet and fertility treatment are limited with many studies lacking the statistical power to validate findings, recent studies corroborate the importance of a balanced diet and appropriate weight management program while undergoing fertility treatment.

SUMMARY

The growing reliance on assisted reproductive technologies in conjunction with the increase in the general population's weight and poor nutritional status has raised questions as to the effects of dietary status and weight on fertility treatment outcome. A review of findings thus far indicates potential avenues for future research to further elucidate cytotoxic and genotoxic dietary factors as well as dietary elements that may improve oocyte quality, aid implantation, as well as pregnancy maintenance during the periconception period.
