Is it normal to have a missed abortion in ovodonation?

By Marta Zermiani M.D., Ph.D. (gynecologist).
Last Update: 03/01/2022

Yes, it is possible to have a missed abortion in an IVF treatment with donor eggs.

We define miscarriage as uninduced embryonic or fetal loss before the 20th week of gestation. A missed or delayed abortion is characterized by the arrest of gestation without spontaneous expulsion of the embryo or fetus and usually occurs between the second and third trimester of pregnancy.

As with other types of miscarriages, one of the main causes is a genetic or chromosomal alteration in the development of the fetus. Likewise, infections, endocrine or hormonal disorders or problems in the uterus or cervix can also cause a miscarriage in the first weeks of gestation.

The risk of miscarriage is around 25% after the age of 35, while it increases to 50% in women over the age of 40. If we apply these percentages to egg donation, we know that the risk of miscarriage in egg donation is around 25% because the oocytes come from women under 35 years of age. So it may be normal in an oocyte donation treatment to have a missed abortion.
