Women may face higher risk of stroke after infertility treatment – study

Women who get pregnant after fertility treatment have an increased risk of stroke within a year after giving birth, compared to women who get pregnant naturally. This is evidenced by the results of a study by scientists from the USA, published in the journal JAMA Network, writes The New York Times. The researchers note that the risk of stroke was increased in the first 30 days after giving birth among women who received the treatment. It remained quite high during the first year after childbirth. But the chance of a stroke itself is quite low, with only 37 stroke hospitalizations per 100,000 women treated in the US.

Among them were 287,813 patients who underwent infertility treatment. The researchers found that the risk of hemorrhagic stroke (bleeding in the brain) was twice as high among women who underwent fertility treatment compared to those who did not. The risk of ischemic stroke, which occurs when the blood supply to the brain is cut off, was 55% higher compared to women who conceived naturally. At the same time, scientists did not take into account a number of factors that cause stroke, such as smoking, body mass index and hypertension. In an interview, article author and Dr. Kande V. Anant outlined three possible explanations for the link between stroke and infertility treatment. “We know that women who are treated for infertility have certain vascular complications, typically an increased risk of preeclampsia and placental abruption,” he explained. Second, infertility treatment can lead to physiological changes, the study author added. Patients often receive large amounts of estrogen, for example, which can lead to increased blood clotting, a strong risk factor for stroke.
