Follicular ovarian cysts

Follicular cysts develop from a follicle during ovulation, in one or both ovaries. Follicular cysts are the most common type of ovarian cyst and are considered to be a normal part of the ovary going about its business.

Endometrioma (chocolate) cysts

An ovarian endometrioma is where menstrual blood and endometrial cells find their way into the ovary, developing a problematic cyst over time. They are called 'chocolate' cysts because of their chocolate-like appearance.

Cystic teratomas and dermoid cysts – ovarian

A dermoid cyst is a growth in the ovary that contains hair, teeth, bone, and other tissue. A dermoid cyst is not a pregnancy, but a tumour.

Benign ovarian masses

Benign ovarian masses can include non-cancerous tumours or cysts, with most coming and going without symptoms. A benign mass could mean a cyst that develops during or after ovulation, or a tumour that appears out of embryonic tissue.

Ovarian cystadenomas (a cystic ovarian tumour)

A cystadenoma is a (generally) benign tumour on one or both ovaries.

Corpus luteum cyst (a functional ovarian cyst)

A corpus luteum cyst is most often a benign ovarian cyst caused by the process of ovulation that will resolve itself over a period of weeks. These ovarian cysts are benign, which means they are not dangerous.

What are polycystic ovaries?
