New Jersey – Rutgers Robert Wood Johnson Medical School reveals that patients who underwent infertility treatment may experience a higher risk of stroke hospitalization in a study published last Wednesday.

During that study, experts found that infertility treatment is associated with an increased risk of stroke hospitalization within 12 months of delivery.

Medical experts describe infertility as not being able to get pregnant. The Centers for Disease Control and Prevention reports that infertility is a common problem for many U.S. women. The same report also underlines that about 1 in 5 married women aged 15 to 49 years old with no past births cannot get pregnant after one year of trying. 

This recent study found that 0.9% of women around 32 delivered after receiving infertility treatment, while 99.1% of women around 27 delivered after pregnancy occurred naturally without treatment.

The experts additionally prove that the group of women who undergo infertility treatment is aged between 30-34, the highest category report in that study. However, that research report a rate of 0.6% of the cohort they study who are under 20 years old also used infertility treatment.

CDC’s medical experts, in a recent publication, outline some common medicines used to treat infertility in women. Among these treatments are clomiphene citrate, letrozole, human menopausal gonadotropin, follicle-stimulating hormone, and gonadotropin-releasing hormone. Those medications or medicines are the most used in the U.S. to treat infertility in women.

Experts said infertility treatment observed from 2010-2018 is associated with an overall 66% increased risk of stroke hospitalization.

Furthermore, they explain that the risk was more significant for hospitalization for hemorrhagic stroke than for ischemic stroke.

However, the study reveals that, during the last decade, assisted reproductive technology has doubled, and roughly 2% of all live births in the U.S. involve some ART method. According to the CDC, assisted Reproductive Technology (ART) includes all fertility treatments in which eggs or embryos are handled outside the body.

Again, the CDC says the leading causes of infertility are disruption of ovarian function, fallopian tube obstruction, or physical characteristics of the uterus. Doctors can treat them with medicine, surgery, intrauterine insemination, or assisted reproductive technology.

With that study, researchers seek to demonstrate whether receiving infertility treatment is associated with stroke hospitalization.

In contrast, Chian Liang, a medical expert, led a retrospective cohort study in 2019 and concluded that infertility, miscarriage, and stillbirth were associated with an increased risk of stroke, especially recurrent miscarriages and stillbirths.
