Will ovarian teratoma affect pregnancy?

Whether ovarian teratoma affects pregnancy needs to be comprehensively judged based on the nature, size and location of the tumor. Most benign teratomas have no significant impact on fertility, but if they are large or have complications such as torsion and rupture, they may interfere with conception or the pregnancy process.

Ovarian teratomas are common germ cell tumors, mostly benign mature teratomas. If the tumor is less than 5 centimeters in diameter and does not compress the ovarian tissue, it usually will not interfere with follicle development and ovulatory function. Small teratomas discovered before pregnancy can be observed regularly. Some patients may experience an increase in tumor size due to hormone stimulation during pregnancy, but the probability of malignant transformation is extremely low. It is common in clinical practice for asymptomatic patients to conceive naturally and give birth at term. Ultrasound monitoring is the main method to evaluate tumor dynamics.

When the diameter of the teratoma exceeds 5 cm or is located in the ovarian hilum, it may mechanically hinder the function of the fallopian tube in picking up eggs or destroy the normal ovarian cortex. Secondary torsion or rupture of the tumor can lead to an acute abdomen, which may lead to miscarriage or premature delivery. Although malignant types such as immature teratomas are rare, they need to be ruled out through tumor markers and pathological examination. For patients who want to have children, laparoscopic tumor removal can preserve healthy ovarian tissue, and pregnancy can be attempted 3-6 months after surgery.

It is recommended to undergo gynecological ultrasound and tumor marker testing before planning a pregnancy. If teratoma is found during pregnancy, the frequency of prenatal check-ups should be strengthened. Postoperative patients should pay attention to the evaluation of ovarian reserve function, and if necessary, use reproductive medicine technology to assist in conception. Maintaining a regular schedule and a balanced diet can help maintain a stable ovarian microenvironment.
