The corpus luteum grows in the trabecular space created by the collapse of the follicular wall after ovulation and is a capillary-rich, large, endocrine-functioning mass of cells called the corpus luteum because of its yellow color when fresh.
The length of time the corpus luteum is present is related to whether the egg is fertilized or not. If the egg is successfully fertilized and pregnancy begins, the corpus luteum continues to grow and secretes the natural progesterone hormone progesterone to maintain the pregnancy until 6 months of gestation or longer when it slowly shrinks.
The mature corpus luteum is 2 to 3 cm in diameter and is a cystic structure that can increase in size to more than 3 cm if fluid accumulates in the luteal cavity.
Because the corpus luteum is located on the surface of the ovary, it is brittle, inelastic, with high surface tension and abundant blood vessels, so it may rupture under the action of external forces such as too intense sexual life, running, jumping and high intensity fitness.
The rupture of the corpus luteum is mostly seen in young and middle-aged women who are sexually active. This is because during sexual intercourse, the female pelvic vascular expansion and congestion, the pressure inside the corpus luteum also increased, the corpus luteum surface tension increased, coupled with abdominal impact, can lead to corpus luteum rupture.
Severe abdominal pain accounts for 95%, accompanied by symptoms of anal swelling, nausea and vomiting are predominant, accounting for 50% and 40% respectively, this symptom is related to the rupture of the corpus luteum blood flow to the abdominal cavity, stimulating the peritoneum. When there is not much bleeding, the body’s blood clotting mechanism can start to stop bleeding on its own, and abdominal pain will also be slowly relieved. When the blood vessels at the bleeding site are thick and the bleeding is extensive, the patient may appear pale, sweating profusely, blood pressure drops, limbs are cold, followed by fainting and other manifestations of hemorrhagic shock.
Sudden and severe abdominal pain in the second half of the menstrual cycle, especially in women after intense sexual intercourse and fitness exercise.
Women with recent ultrasound suggestive of ovarian enlargement or ovarian cysts.
Women who receive anticoagulation therapy, have abnormal coagulation function or bleeding that does not stop easily.
Women with abdominal pain and ultrasound suggestive of pelvic and abdominal fluid with negative HCG (human chorionic gonadotropin).
Knock on the door: Seek medical attention in the event of abnormal abdominal pain. Because ruptured corpus luteum is easily confused with acute appendicitis, ovarian tumor torsion and ectopic pregnancy rupture, it is sometimes easily misdiagnosed and even life-threatening in serious cases.
Drawing focus: If you have ovarian corpus luteum cyst, there is no clear way to prevent rupture, but daily life of the second half of the menstrual cycle if you do the following 5 points, can greatly reduce the probability of corpus luteum rupture.
1. Do not exercise strenuously, especially strenuous exercise of the abdomen.
2. Avoid vigorously squeezing and hitting the abdomen, and do not move too vigorously during intercourse.
3. Eat a balanced diet and keep your intestines open.
4. Have regular gynecological examinations.
5. Pay attention to rest and keep your mood happy.
