Extrauterine pregnancy after IVF occurs in 3% to 5 % of patients. Up until recently surgery - Fallopian tube removal - had been the only method for its treatment. Today it has become possible to avoid traumatic operation. With ultrasonic guidance the puncture of gestational sac, located outside the uterus, is made. A medicine that stops further development of pregnancy is injected into its cavity. The gestational sac fully resolves after this procedure.

After IVF multiple pregnancies occur more often than usually (1% in spontaneous pregnancies) and make up about 24%. Such a high rate in the quantity of multiple pregnancies after IVF is mainly connected with the transfer of several embryos into the uterus. Multiple pregnancy is often complicated by spontaneous miscarriage and preterm delivery (up to 50%). To reduce the noncarrying of pregnancy frequency, selective reduction is conducted.

This procedure is carried out in case of multiple pregnancy after 7 weeks of pregnancy to prevent noncarrying, which in this case occurs 3-4 times more often than insinglet pregnancies.  Selective reduction is termination of fetus development by way of gestation sac puncture through posterior vaginal vault with ultrasonic guidance.

Parents are very often concerned about health of the child, conceived in vitro. The number of children around the world who were born owing to IVF application is already over 5 million. The occurrence of handicaps does not exceed that in children conceived ordinarily. Besides, apart from that with the help of IVF it is possible to reduce the number of children born with genetic diseases to zero.
