Ovarian cysts and infertility: Is there a connection?

Yes, some ovarian cysts contribute to infertility. However, it depends on the kind of ovarian cyst you have. There are several types of ovarian cysts:

• Functional cysts. Functional cysts are the most common type of ovarian cyst. Functional cysts form during a normal menstrual cycle and do not cause or contribute to infertility. In fact, functional cysts actually indicate that the necessary functions leading to fertility are taking place.
• Cystadenomas. These cysts are growths in the ovary that arise from the outside lining of the ovaries, although they need treatment, they don't affect fertility.
• Dermoid cysts. These cysts contain tissue — such as skin, hair or even teeth — instead of fluid. Dermoid cysts don't affect fertility.
• Endometriomas. Endometriomas are cysts caused by endometriosis, a condition in which the tissue normally lining your uterus (endometrium) grows outside the uterus. This type of ovarian cyst does have a detrimental effect on fertility.
• Polycystic ovaries. Polycystic ovary syndrome (PCOS) is a condition marked by many small cysts in your ovaries, irregular periods and high levels of certain hormones. PCOS does contribute to infertility.

If you've been diagnosed with an ovarian cyst and are concerned about becoming pregnant, talk to your doctor.
