A new study has revealed that fertility treatments to induce pregnancy in a woman could increase the risk of heart diseases later in life.

The study included 28,442 female participants aged less than 50 years old who underwent fertility treatments in Ontario between 1993 and 2011. Each of them was updated until March 2015, but only almost one-third of the women became pregnant within a year.

The remaining respondents are 19 percent at risk of adverse cardiovascular diseases including heart failure. However, the finding is relatively modest since it is possible for ten out of 1,000 women after ten years. According to The Cut, it is also possible for women who became pregnant after undergoing fertility treatment, but only up from six events per 1,000 women. 

Meanwhile, the author of the study said that the long-term impacts of assisted reproductive technology are not yet known. But, according to Time, there are observational studies which suggest a link between ovarian hormone levels and complications during pregnancy.

Most fertility treatments may result in increased ovarian hormone levels. During pregnancy, a woman may suffer from complications like blood clots, high blood pressure, and gestational diabetes.

Lead author Dr. Jacob Udell said that serious side effects of fertility treatments are rare. 

Scientists at the Institute for Clinical Evaluative Sciences and cardiologist at the Peter Munk Cardiac Centre and Women's College Hospital further said that it is unclear if these same things also occur among women at a very low level. They also want to find if these women may manifest symptoms in the future.  

Fertility treatment may be a right choice for many women, but experts suggest that factors, including the potential side effects as well as long-term risks, should be considered carefully.
