Ovarian cysts after in vitro pregnancy do not necessarily have an effect on the fetus, if they are physiological cysts, they usually do not have an effect, if the cysts are large or pathological cysts, they will have a certain effect. If the ovarian cysts are physiological cysts, commonly luteal cysts, they usually subside on their own and generally do not affect the growth and development of the fetus. If the ovarian cyst is large or occupies a place in the pelvis, it will affect the growth and development of the fetus. In this case, in order to prevent rupture of the cyst or cyst torsion, it needs to be evaluated by a doctor to choose an appropriate time for surgical removal. If the cyst is malignant, follow-up treatment may be required. After in vitro pregnancy with ovarian cysts, you need to go to the hospital for regular checkups, and once the ovarian cysts affect the health of the fetus, you need to take surgical treatment under the guidance of the doctor.
