Ovarian rupture occurs when the wall of a mature follicle or corpus luteum is broken due to some reason, causing bleeding. In severe cases, it can lead to a large amount of intra-abdominal bleeding. This is known as ovarian rupture, and it includes follicular rupture and corpus luteum or corpus luteum cyst rupture. It can occur in both married and unmarried women, with the most common occurrence in women of childbearing age.
