The corpus luteum of the ovary may rupture spontaneously or under the action of external forces. 1. Spontaneous rupture: The corpus luteum is rich in blood flow. If the blood vessels inside it rupture and bleed, it may cause the pressure inside the corpus luteum to rise, and the corpus luteum itself has poor elasticity, in which case, the corpus luteum may undergo spontaneous rupture. 2. External rupture: (1) Sexual life is intense: if the male partner moves more roughly during sex, resulting in a strong impact on the woman’s abdomen, rupture of the corpus luteum may occur. (2) Strenuous exercise: when running or jumping strenuously, or coughing hard, it may also lead to a sudden increase in intra-abdominal pressure, causing the corpus luteum to rupture. (3) Medical factors: If improper force is applied during gynecological examination, it may also lead to luteal rupture. Rupture of the corpus luteum is very dangerous, and if the bleeding is heavy, it may even result in shock, which is life-threatening. If a woman suddenly develops symptoms of abdominal pain, she should consult a doctor in time to clarify the cause.
