What causes luteal phase vaginal bleeding?

Women's physical health is a very important matter because women's bodies are relatively more fragile and more susceptible to diseases. Gynecological diseases, in particular, have a great adverse impact on the lives of more and more women. For example, women are more likely to have reproductive system problems during the luteal phase, causing women to suffer greater physical pain. Let’s take a look at what causes luteal phase vaginal bleeding.

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 and significantly, which cannot maintain the growth of the endometrium, causing local ulceration and shedding of the surface layer of the endometrium, resulting in a small amount of breakthrough bleeding, and with the formation of the corpus luteum of the ovary.

Sufficient estrogen and progesterone are secreted to quickly repair the ruptured surface of the endometrium and stop the 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 fimbria of the fallopian tube, the blood-containing follicular fluid is sent to the uterine cavity through the retrograde peristalsis of the fallopian tube and then flows out of the cervix through the vagina.

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 a microscope, 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.

It may also be due to an imbalance in sex hormone secretion, which causes large fluctuations in hormone levels during ovulation and leads to 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.
