Ovarian cysts are fluid-filled sacs that form on the ovaries. Most ovarian cysts are harmless and go away on their own, but some can cause serious symptoms. The causes of ovarian cysts can vary and include:

• Functional cysts: These are the most common type of ovarian cyst and occur as a result of ovulation. They are not disease-related and usually go away on their own within 60 days.

• Pathological cysts: These are caused by abnormal cell growth and are not related to the menstrual cycle. They can develop before and after menopause and can sometimes burst, twist, or grow very large and block the blood supply to the ovaries.

• Endometriomas: These are caused by endometriosis, a condition where tissue similar to the lining of the uterus grows in other places, such as the ovaries and fallopian tubes.

• Dermoids: These come from cells present from birth and do not usually cause symptoms.

• Cystadenomas: These are filled with watery fluid and can sometimes grow large.

Other causes of ovarian cysts include hormonal problems, pregnancy, severe pelvic infection, and previous ovarian cysts. Polycystic ovary syndrome (PCOS) is another condition that can cause ovarian cysts and can also cause problems with the ovaries and getting pregnant.

Its important to note that most ovarian cysts are harmless and do not affect your chances of getting pregnant. However, if you experience symptoms such as pelvic pain, heavy or irregular periods, or abnormal vaginal bleeding between periods, you should see a doctor.
