Ovarian teratomas are a common type of benign ovarian tumor, and most ovarian teratomas do not affect the ability to become pregnant. This is because ovarian teratomas generally do not cause ovulation disorders, do not affect the function of the fertilized egg, and typically do not lead to pelvic inflammation, so the majority of patients with ovarian teratomas can become pregnant normally. However, if the ovarian teratoma is relatively large, greater than five centimeters, this condition may affect the function of the ovaries, or cause the teratoma to rupture or become infected after pregnancy. For teratomas larger than five centimeters, it is generally recommended to undergo laparoscopic surgery to remove the teratoma before attempting pregnancy, to prevent the teratoma from affecting the pregnancy.
