Corpus Luteum Cyst

What is Corpus Luteum Cyst?

Corpus luteum cyst also termed as ‘functional ovarian cyst’ is a type of cyst that develops in the ovaries. During the menstrual cycle, an egg grows within a sac and the pouch is called follicle. If the follicle releases the egg and the egg bursts out emptying the space, then it forms corpus luteum. However, if it contains fluid and the opening of the follicle seals, then corpus luteum cyst is formed.

Corpus Luteum Cyst during Pregnancy

Mostly, it does not cause any problem during pregnancy but remains present in the ovary. However, miscarriages can be a possibility in only a few women. During the early stages of pregnancy, the cyst stays until the later trimester and can finally disappear. But if the cyst is larger in size and causes excessive bleeding or mild pain, then removal of it may be needed before pregnancy. The cyst can also be an indication of a woman being pregnant.


There is a limited possibility for the presence of corpus luteum cyst in women and even they do not have the same symptoms. During pregnancy, women might experience pain and tenderness in the pelvic region. In some cases, the cyst may put pressure on the ovary which can be detected by bloating, pain and frequent urination. Often suffering from a twisted ovary is the first indication for a woman of something severe.

Other symptoms include:

  • Pain during exercise or sexual intercourse
  • Back pain
  • Late periods or missed periods for more than one cycle
  • Irregular or spotty bleeding
  • Cramping

A ruptured corpus luteum cyst can cause complications like:

  • Infection
  • Adhesions
  • Fever
  • Vomiting
  • Severe pain
  • Excessive bleeding


  • Ultrasound
  • Blood test


Usually, the cyst goes away on its own, but if it causes bleeding and severe pain, then surgery can be an option. However, operations leave scars and adhesions which can affect a woman to become pregnant again if any type of damage occurs in the ovaries. It is possible to do surgery with a laparoscope termed as band-aid surgery.
