Pregnancies from IVF or SO-IUI

IVF refers to in vitro fertilization while SO-IUI refers to super ovulation in utero insemination. These procedures are assisted reproductive techniques that are used for couples who have difficulty to conceive.

Risks of IVF and SO-IUI pregnancies include:


The rate of miscarriage for women who conceive using IVF with fresh embryos is similar to that of women who conceive naturally — about 15% to 25% — but the rate increases with maternal age.

Ectopic pregnancy

About 2% to 5% of women who use IVF will have an ectopic pregnancy — when the fertilized egg implants outside the uterus, usually in a fallopian tube. The fertilized egg can't survive outside the uterus, and there's no way to continue the pregnancy.

Multiple pregnancies

IVF and SO-IUI contribute to the increase in twin, triplet and other higher order multiple pregnancies A pregnancy with multiple fetuses carries a higher risk of premature labor and small babies than a pregnancy with a single fetus does.

Birth defects

The age of the mother is the primary risk factor in the development of birth defects, no matter how the child is conceived. Some data suggests that babies conceived using IVF may be at increased risk of certain birth defects.

Premature delivery and low birth weight

Even if the pregnancies resulting from IVF and SO-IUI are singleton pregnancies, there are slight increases in the risk that the baby will be born early or with a low birth weight.


Use of IVF can be financially, physically and emotionally draining. Support from counselors, family and friends can help you and your partner through the ups and downs of infertility treatment.
