Endometriosis most commonly affects which site?

Endometriosis most commonly affects which site?

• A. Liver
• B. Ovaries
• C. Lungs
• D. Brain

Answer: (B)

Endometriosis involves endometrial-like tissue growing outside the uterus, and the ovaries are the most frequent site because they are a common pelvic location where implants can establish and grow. When the ovaries are involved, they often form endometriomas, or “chocolate cysts,” which are a classic finding in this disease. While endometriosis can affect other organs, the liver, lungs, and brain are much rarer sites, making ovarian involvement the typical presentation.
