Patient's question:
Doctor, Hello: Female, 28I am 7 weeks pregnant. Yesterday, I had an ultrasound examination and found corpus luteum cysts measuring 8.2 cm and 6.1 cm. The doctor said they are larger than normal and that the cyst walls are thin, so I need to be careful not to squeeze them. The ultrasound showed that the embryo is developing well and there is a fetal heartbeat. I would like to ask you: Why do corpus luteum cysts form? If they do not absorb on their own after 3 months, will they affect the fetus? What should I pay attention to? Thank you!
Medical History: None
Doctor's answer:
Follicular cysts are a relatively common phenomenon in the early stages of pregnancy. After ovulation, mature follicles form the corpus luteum. During the vascularization phase, blood flows into the corpus luteum cavity (corpus luteum hematoma), so under normal conditions, the corpus luteum is cystic. In pathological cases, if its diameter is 1.5–2.5 cm, it is called a corpus luteum cyst; if it exceeds 2.5 cm, it is referred to as a corpus luteum cyst. The corpus luteum cyst is a physiological cyst, which generally gradually shrinks or disappears after the 8th week of pregnancy and has no significant impact on the health of the fetus or the pregnant woman. As long as there are no symptoms such as severe abdominal pain or vaginal bleeding at present, continue to monitor and undergo regular check-ups.
