Losing Weight Before IVF May Increase Chance of Pregnancy

ENGLAND, UNITED KINGDOM, AUG 12 – A review of 12 trials found weight loss before IVF is linked to higher pregnancy rates but live birth benefits remain unclear due to small, biased studies, researchers say.

Summary by Medical Xpress
A systematic review and meta-analysis of randomized controlled trials (RCTs) assessed whether weight loss interventions before in vitro fertilization (IVF) improved reproductive outcomes. The review found that weight loss interventions before IVF could increase the chances of pregnancy, especially in unassisted conception, although the effect on live births was unclear. The findings are published in Annals of Internal Medicine.
