Why does bleeding occur during sexual intercourse?

There are many reasons for bleeding during sexual intercourse. Apart from the normal situation where the hymen of some female friends ruptures and causes bleeding after the first intercourse, most of them are caused by diseases and should not be underestimated. Bleeding during sexual intercourse is usually one of the symptoms of cervical cancer, which brings panic and anxiety to female friends. Now let me tell you what is going on.

What causes bleeding during intercourse?

1. Rough sex causes vaginal tearing

Excessive and violent sexual movements, or roughness on the part of the man, can easily cause lacerations of the vaginal mucosa, leading to bleeding, usually fresh blood. If foreplay is not enough and the vaginal wall is not fully relaxed and expanded, it can easily cause tearing of the vaginal wall.

2. Cervical erosion causes bleeding during sexual intercourse

Cervical erosion is the most common. Due to long-term inflammatory stimulation, the squamous epithelium on the surface of the cervix falls off, and the peeling surface is gradually covered by the proliferating columnar epithelium. The columnar epithelium is very thin, and underneath it are blood vessels and interstitium. During sexual intercourse, the penis is in direct contact with the cervix, so it is easy to bleed during sexual intercourse.

3. Cervical polyps cause contact bleeding

Why do cervical polyps cause bleeding during sexual contact? Because there is a type of polyp attached to the cervical opening or the cervical canal, and the surface of the polyp is covered with a layer of columnar epithelial cells, which makes bleeding easy to occur during sexual contact. It should be pointed out that the symptoms of cervical polyps are usually not obvious. Most patients only have symptoms such as increased vaginal discharge, blood streaks, or bleeding during sexual intercourse.

4. It is normal to bleed during intercourse right after menstruation

When menstruation has just ended, sexual intercourse can cause bleeding because the vagina and endometrium have just been repaired. This is normal. Generally, you don't need to worry too much about it. However, we generally recommend that women have sex after their menstruation is over. Having sex during menstruation may cause uterine infection and even lead to infertility and other problems.

The above are the reasons for bleeding during sexual intercourse. If the bleeding is not accidental and occurs repeatedly, then disease factors should be considered. If you suspect you have a disease, you must seek prompt examination and treatment, and never be afraid to seek medical attention. The editor would also like to remind everyone that for the sake of physical health, it is best to have regular check-ups to rule out the possibility of disease.
