Does infertility treatment increase the risk of stroke? A US study involving women who delivered through spontaneous conception and those who underwent infertility treatment has claimed that the latter is at higher risk of suffering from stroke, reports Durgesh Nandan Jha. Infertility treatment included intrauterine insemination and assisted reproductive technology among others.
According to the study published in the Journal of American Medical Association (JAMA) Network, those who received infertility treatment had a 66% increased risk of hospitalisation due to stroke within 12 months of delivery as compared to those who conceived spontaneously.
“Obesity, hypertension and diabetes that are known risk factors for stroke are more common in women suffering from infertility than those who don’t,” said Dr Shamsher Dwivedee, director of neurology at Max Dehradun.
In the study, researchers screened data of 3.1 crore women who delivered babies in the US between 2010 and 2018. Of them, 2.8 lakh had undergone infertility treatment while the rest delivered after spontaneous conception. The rate of stroke hospitalisation within 12 months of delivery was 37 hospitalisations per 1,00,000 patients among those who received infertility treatment and 29 hospitalisations per 1,00,000 patients among those who delivered after spontaneous conception, according to the study. The risk of hospitalisation for haemorrhagic stroke was greater than that for ischemic stroke, it found.
Researchers from Rutgers Robert Wood Johnson Medical School and New Brunswick, New Jersey, led the study.
