New study finds higher stroke risk for women after infertility treatment

Women who became pregnant through infertility treatment had higher stroke risk after giving birth than those who conceived naturally.
Risk was highest in the first 30 days after delivery and continued to increase over the following year.
The number of strokes was relatively low, affecting about 37 out of 100,000 treated women.
Stroke accounts for around 7.5% of pregnancy-related deaths in the U.S., which has the highest maternal mortality rate.
Use of assisted reproductive technology has risen, now accounting for 2% of U.S. births.
