The incidence of hypertensive complications was significantly lower in the group of women treated with low-dose aspirin throughout IVF treatment and first trimester of pregnancy. These results suggest a potential benefit of low-dose aspirin during IVF and first trimester to prevent hypertensive pregnancy complications. The findings justify further investigation in placebo-controlled randomized trials.

Based on the current meta-analysis with IPD we found no confirmation for the hypothesis that preconceptionally started low-dose aspirin reduces the incidence of hypertensive pregnancy complications or preterm delivery in IVF women. Larger studies are warranted.

Aspirin does not improve pregnancy rates after IVF.

The majority of women with a history of early-onset pre-eclampsia achieve or wish to achieve a second pregnancy within a few years of their delivery. Nonetheless, first pregnancy early-onset pre-eclampsia appears to have a significant impact on future reproductive health and decision-making, emphasizing the importance of careful post-partum counseling.
