If it is confirmed that there is an ovarian teratoma, normally, its impact on pregnancy is not significant. However, the teratoma may grow rapidly due to hormonal influences. If the specific pathological nature of the teratoma can be determined and malignancy is ruled out, it is possible to temporarily observe the condition. During the entire pregnancy, close monitoring of the growth of the tumor is necessary. It is feasible to perform a cesarean section during a normal full-term delivery, and remove the ovarian teratoma surgically, achieving complete cure.
