Infertility is a global health issue, and its association with obesity is not well understood. Studies have found that preconception maternal weight is inversely correlated with live birth rates. However, there is insufficient evidence for the effectiveness of preconception lifestyle interventions or pharmacological interventions in obese women with infertility. This has implications for clinical practice and future research.
Infertility is a significant global health issue, with a negative impact on people's wellbeing and human rights. Despite the longstanding association between obesity and infertility, there remains uncertainty, about the precise mechanisms underpinning this association and best management strategies. In this article, we aimed to address these uncertainties by reviewing the recent literature, and focusing on studies which evaluated live birth rates. We found that just over half of the studies, investigating the relationship between preconception maternal weight and live birth rates found an inverse correlation. There was, however, insufficient evidence, that preconception maternal lifestyle or pharmacological interventions in obese women with infertility, resulted in improved live birth rates. The implications for clinical practice and future research are highlighted. For example, the need to consider some flexibility in applying strict preconception body mass index targets, limiting access to fertility treatment, and a need for large clinical trials of new pharmacological options and bariatric surgery.(C) 2023 Published by Elsevier Ltd.
