Why does the corpus luteum rupture?

When you go to the hospital and find out that your corpus luteum has ruptured, you will feel very panicked because you don't know when the corpus luteum ruptured. There are several main factors that affect the corpus luteum rupture. It may rupture automatically, or it may be caused by external force or impact from heavy objects. If you have done any jumping exercises, or suddenly raised your head or stood up, it may be damaged due to compression. It is also not ruled out that it is related to sexual life.

1. Causes of Corpus Luteum Rupture:

1. Spontaneous rupture: Under normal circumstances, there is a small amount of bleeding in the corpus luteum, but if there is too much bleeding, it may increase the pressure in the corpus luteum, resulting in spontaneous rupture. Some people believe that during the period of luteinization, vascular dysfunction occurs, which makes capillary bleeding in the corpus luteum prone to occur, leading to corpus luteum rupture.

2. External force: If the lower abdomen is hit, or when jumping, running, coughing or defecating violently, the pressure in the abdominal cavity suddenly increases, which can cause the mature corpus luteum to rupture. In addition, during sexual intercourse, the female reproductive organs expand and become congested, the tension in the corpus luteum increases, and the man's rough movements cause a strong impact on the woman's lower abdomen, which can also lead to rupture of the corpus luteum.

3. Caused by sexual intercourse: During sexual intercourse, the reproductive organs expand and become congested. When reaching orgasm, the muscle tissue may contract spasmodically, causing the tension in the corpus luteum to increase. If the male has rough sexual intercourse and the woman's lower abdomen is strongly impacted, it will cause the corpus luteum to rupture. Therefore, when a woman experiences lower abdominal pain after sexual intercourse, she must not be careless.

2. Diagnosis of Corpus Luteum Rupture:

Because its clinical manifestations are not typical, the main clinical symptoms are sudden onset of abdominal pain with varying degrees of pain. Some patients have varying degrees of anal distension. In severe cases, massive bleeding and even shock may occur, endangering life and requiring urgent surgery. The onset is acute, and there is currently no special examination method to make a clear diagnosis. The misdiagnosis rate is high and it is easily confused with acute abdomen such as ectopic pregnancy, acute pelvic inflammatory disease, acute appendicitis, ureteral stones, and ovarian tumor pedicle torsion.

Main diagnostic basis:

1. The patient has no history of amenorrhea, and the onset of the disease often occurs between two menstrual periods or before menstruation; there is a history of onset after sexual intercourse.

2. The onset is sudden, with sudden severe pain in the lower abdomen, which becomes continuous pain after a short time, and may gradually ease or become severe again. A small number of patients may experience nausea and vomiting. There is generally no vaginal bleeding (external bleeding). Severe internal bleeding may cause shock and rectal irritation symptoms.

3. Abdominal examination: obvious tenderness and rebound tenderness. If there is a lot of internal bleeding, there will be mobile dullness on percussion.

4. Vaginal examination: The uterus is of normal size, the posterior fornix is ​​tender, and a soft mass with unclear boundaries and tenderness can be felt in the adnexa.

5. White blood cell count and classification, neutrophil percentage increased, red blood cells and hemoglobin decreased.

Corpus luteum rupture often occurs on the right side, but lacks typical symptoms and should be differentiated from acute appendicitis, ruptured fallopian tube pregnancy or miscarriage.

During the development of the corpus luteum, the small blood vessels on the surface of the ovary may be damaged by chance, causing internal bleeding in the corpus luteum, leading to increased internal pressure and rupture, which is called ovarian corpus luteum rupture. Severe cases can cause massive intra-abdominal bleeding, which is ovarian rupture.
