Introduction

After ovulation, the follicular wall collapses, and the granulosa cells and theca cells of the follicle invade inward. Under the influence of luteinizing hormone (LH), these cells develop into the corpus luteum. The corpus luteum secretes progesterone, which nourishes the endometrium and prepares it for embryo implantation. It plays an important role in maintaining a normal menstrual cycle and supporting pregnancy. Insufficient progesterone secretion by the corpus luteum may lead to menstrual disorders, infertility, and other symptoms.

Under normal circumstances, the corpus luteum is a gland-like structure rich in blood vessels that rapidly transforms from the ovarian follicle after ovulation in women of reproductive age. If any discomfort occurs, it is recommended to seek medical attention promptly. Specific analysis is as follows:

After ovulation, the follicular wall collapses, and the granulosa cells along with the internal theca cells invade inward, forming the corpus luteum under the influence of luteinizing hormone (LH). The corpus luteum secretes progesterone, which nourishes the endometrium and prepares the uterus for embryo implantation. It plays a positive role in maintaining regular menstrual cycles, supporting pregnancy, and preserving fertility. Insufficient progesterone production by the corpus luteum may lead to menstrual disorders, infertility, or miscarriage. Patients with luteal phase deficiency should, under medical guidance, be treated with medications such as progesterone capsules, recombinant human follicle-stimulating hormone injection, or dydrogesterone tablets.

In daily life, maintaining a balanced diet and appropriately supplementing protein, vitamins, and minerals can help support normal corpus luteum function.

Will a corpus luteum hematoma resolve on its own?

In cases where the corpus luteum hematoma is relatively small, it can often resolve spontaneously without special treatment. However, when the hematoma is large, medical or surgical intervention may be required to prevent complications such as increased bleeding due to delayed treatment. It is also important to promptly address the underlying condition, such as a corpus luteum cyst, to prevent spontaneous rupture or torsion of the cyst's pedicle.

Can a 5 cm corpus luteum cyst heal on its own?

When a corpus luteum cyst is 5 cm in size, if there are currently no symptoms and the cyst shows no signs of continuous growth, it may still resolve spontaneously. However, regular monitoring is necessary, and all strenuous physical activities should be avoided. If the cyst is found to increase significantly in size or is accompanied by symptoms such as abdominal pain or bleeding, prompt hysteroscopic surgery under medical guidance is required to prevent life-threatening complications such as rupture and hemorrhage.

Can bowel movements be passed with a ruptured corpus luteum?

Whether normal bowel movements are possible after corpus luteum rupture depends on the severity. In general, mild corpus luteum rupture does not affect defecation, and most patients can pass stool normally. However, severe corpus luteum rupture may lead to intraperitoneal bleeding, with hematoma formation compressing the rectum and anus, thereby impairing bowel movements. In such cases, timely hemostasis and anti-inflammatory treatment as directed by a physician usually result in gradual symptom relief.

What causes low progesterone levels?

Low progesterone levels may be caused by factors such as different phases of the menstrual cycle, aging, thyroid dysfunction, luteal phase deficiency, or polycystic ovary syndrome. It is important to maintain a balanced diet, consume more fresh vegetables and fruits, and eat protein-rich foods such as fish, meat, and eggs. Avoid staying up late for prolonged periods.
