What is the cause of ovulatory bleeding?

Ovulation bleeding is a phenomenon that many women will find, that is, there is vaginal bleeding during the ovulation period. Many women will panic because they don’t know much about this problem, but in fact ovulation bleeding is a normal phenomenon and does not require special treatment. The reason for ovulation bleeding is mainly caused by a sharp drop in estrogen levels. Of course, it may also be caused by some sex hormone disorders. Therefore, women must pay attention to the problem of abnormal vaginal bleeding. If it is not ovulation bleeding, be alert to whether it is some gynecological diseases, such as irregular menstruation, cervical erosion, cervical cancer and so on.

1. Estrogen levels drop sharply

In fact, ovulation bleeding is a phenomenon that every female friend may experience. Generally, the amount of bleeding is very small and cannot be observed with the naked eye, but some people will have obvious bleeding symptoms, and the severity cannot be generalized. But in fact, the main reason for ovulation bleeding is that after the mature follicle ruptures and ovulates, the estrogen level drops sharply, which cannot maintain the growth of the endometrium, causing local ulceration and shedding of the surface layer of the endometrium, resulting in breakthrough bleeding in small amounts.

2. Not a pathological phenomenon

When examining the cervical mucus of women who ovulate during the mid-term period, it is found that about 60% of them have red blood cells under microscopic observation, but no bleeding can be seen with the naked eye. This is not a pathological phenomenon; but women with ovulation bleeding must rule out other reproductive tract diseases, such as irregular menstruation, cervical erosion, cervical polyps, cervical cancer, endometrial polyps, submucosal uterine fibroids, endometrial adenocarcinoma, etc.

3. Sex hormone secretion disorder

Of course, it is also possible that the secretion of sex hormones is out of balance, causing the hormone levels to fluctuate greatly during ovulation and resulting in obvious bleeding. Chronic inflammation of the endometrium or inflammatory thickening of the ovarian surface causes significant endometrial congestion during ovulation, and bleeding is not easy to stop on its own, or the inflammatory thickened follicle surface ruptures and bleeds more than normal, and flows back into the uterine cavity with the peristalsis of the fallopian tube and is discharged from the body through the vagina.

Vaginal bleeding visible to the naked eye may last for several hours, or 3 to 5 days, but rarely for more than 7 days. In severe cases, it may continue to occur until the next menstrual period. Some women have very little bleeding, which stops with a few drops, or there is blood mixed in the vagina. Generally, it rarely reaches the amount of menstruation. Bleeding may be accompanied by distension and discomfort, dull pain or obvious pain in one side of the lower abdomen, and may even involve the waist and inner thigh. Symptoms may occur continuously every month or every other month. For some people, they occur for several months each year, while for others, they only experience this phenomenon once in their lifetime.
