Why does ovulation bleeding occur?

Many women have experienced ovulation bleeding, but most people don’t know why women bleed during ovulation. When this happens, you can actually consider whether it is related to your own lifestyle and eating habits that lead to a decrease in estrogen.

1. The reason for ovulation bleeding is that after the mature follicle ruptures and ovulates, the estrogen level drops sharply and significantly, which cannot maintain the growth of the endometrium, causing local rupture and shedding of the endometrial surface, resulting in breakthrough bleeding. With the formation of the corpus luteum of the ovary, sufficient estrogen and progesterone are secreted to quickly repair the ruptured endometrial surface and stop bleeding. Or it is possible that during ovulation, the mature follicles secrete more estrogen, causing endometrial congestion and leakage of red blood cells. It is also possible that when the egg is captured in the fallopian tube fimbria, the blood-containing follicular fluid is sent to the uterine cavity through the retrograde peristalsis of the fallopian tube and then flows out from the cervix through the vagina.

2. Uterine bleeding. During the menstrual cycle with ovulation, ovulation uterine bleeding occurs. The amount of bleeding is small, and some are only brown secretions. It usually stops on its own in 2 to 3 days, and the longest time is 7 days.

3. Abdominal pain. Cyclic intermenstrual pain can be mild or severe and generally lasts for several hours, but in some patients it may last for 2 to 3 days.

4. Infertility. It may be caused by stopping sexual life due to ovulation bleeding, thus missing the opportunity of conception. Note: Generally there are no obvious positive signs. The diagnosis can be confirmed by diagnostic curettage, basal body temperature measurement (basal body temperature is biphasic, and bleeding occurs when low and high temperatures change), and laparoscopy. If the symptoms are mild, no treatment is needed. If the bleeding is heavy or affects fertility, medication can be used for treatment.
