Assisted Reproduction: No Birth Defect Risk
But Women Who Conceive With Help From Medical Science May Have More Pregnancy Complications
Is Treatment the Cause?
It is not known why women treated with ART are at higher risk, but there is a high suspicion that the same medical issues that contribute to infertility contribute to pregnancy complications.
"It should not be surprising that women who had a medical problem that made it difficult for them to get pregnant also had problems once they became pregnant," says William Gibbons, MD, who is president of the Society for Assisted Reproductive Technology.
ART procedures are commonly performed on women who have no identified cause for their infertility, University of Vermont gynecology professor Julia Johnson, MD, tells WebMD.
"Since we don't have a good understanding of what causes their infertility, the fact that these women may have complications in pregnancy is not too surprising," she says.
The experts agreed that women considering ART should be counseled about the risk of pregnancy complications. But Shevell tells WebMD that pregnancies that result from treatment should not automatically be considered high risk.
"These are patients who need to be treated with a little more scrutiny during pregnancy," she says. "But most general ob-gyns are comfortable treating these conditions, and outcomes are generally good."
