Does pregnancy with an ovarian corpus luteum cyst have a significant impact on the fetus?

Patient's question:

Anterior uterine position; Anteroposterior diameter 4.8 cm, homogeneous endometrial echo; An intrauterine 1.5×1.0×2.1 cm gestational sac echo was observed, with regular morphology. No embryonic echo or old cardiac tube was seen inside. The yolk sac had a diameter of approximately 0.3 cm, with regular morphology, clear boundaries, increased posterior echo, and linear blood flow patterns on the wall. No mass was observed in the left adnexal region. Suggestion: Right ovarian corpus luteum cyst

Doctor's answer:

The corpus luteum cyst itself will never interfere with fetal growth and development, unless it ruptures again or reverses, requiring surgical treatment. It is recommended that you rest and avoid strenuous exercise. Generally, the cyst will gradually increase in size after the 12th week of pregnancy. Additionally, patients should maintain a regular schedule, take precautions against cold and keep warm, eat light and soft foods, ensure good ventilation, and drink plenty of hot water to prevent the condition from recurring.
