PE risk for pregnant women after IVF

Swedish researchers looked at 23,498 women who gave birth after IVF between 1990 and 2008 and 116,960 women matched for age who had natural pregnancies. Their median age was 33 years.

The proportion of women who had undergone IVF diagnosed with VTE was 4.2 in 1000 compared to 2.5 in 1000 unexposed women.
