Rupture of a blood vessel at ovulation typically results in which type of ovarian cyst?

• A. Hemorrhagic Cyst
• B. Follicular Cyst
• C. Corpus Luteum Cyst
• D. Dermoid Cyst

Answer: (A)

During ovulation the dominant follicle ruptures to release the egg, and the tissue is highly vascular. If a blood vessel at that moment bleeds into the follicle, blood fills the cavity and a hemorrhagic cyst forms. This is a classic functional cyst that arises from ovulatory bleeding and is typically benign, often resolving on its own over time.

A follicular cyst, by contrast, happens when a follicle fails to rupture and simply enlarges instead of bleeding. A corpus luteum cyst forms after ovulation as the ruptured follicle luteinizes; it can be hemorrhagic too, but its origin is post-ovulation luteinization rather than bleeding at the moment of ovulatory rupture. Dermoid cysts are benign germ cell tumors that are not related to ovulation or vessel rupture.
