Causes of Post-Coital Bleeding
Post-coital bleeding is usually caused by vaginal dryness, which in turn can have multiple causes.
Post-coital bleeding is bleeding that occurs in women after sexual intercourse. The medical term used to refer to this situation is PCB. It’s a fairly common occurrence that isn’t related to menstruation.
Many women who experience this post-coital bleeding tend to panic. However, specialists estimate that it happens in about 10% of women. Moreover, half of the cases clear up spontaneously because they have don’t have any pathological cause.
In fact, there are many situations that can cause this post-coital bleeding. In this article, we’ll explain the most relevant situations so that you know what you can do if it happens to you. It’s important to know that the best idea is always to consult a doctor if you have any doubts.
Why does post-coital bleeding occur?
As we’ve already mentioned, post-coital bleeding has a very varied etiology. In fact, it’s most commonly due to some non-pathological cause that can be resolved spontaneously, such as a small wound from the friction of sex. Other possible causes are:
- Vaginal dryness. This same dryness is the one that causes some small tears during friction. It’s very common that, if you aren’t sufficiently aroused or you’re nervous, the vagina isn’t as moist as it should be. In these cases, using a good lubricant can be the solution.
- Oral contraceptives. These are medications that alter a woman’s hormonal cycle. Hormones have a significant impact on vaginal moisture, so contraceptives are also associated with dryness.
- An infection – either a sexually transmitted disease or a fungal or bacterial infection of the vagina. It’s very important to know that post-coital bleeding can be one of the first signs of STDs. Always see your health care provider to explore this possibility and treat it.
Infections are much more common than we think. In fact, as we’ve just mentioned, they aren’t always STDs. Many women experience bacterial or fungal infections throughout their lives due to a simple lowering of defenses or other reasons.
Pathological post-coital bleeding
On the other hand, it is true that this post-coital bleeding may have more serious causes. Although not as frequent, the bleeding may be due to an endometrial polyp, a uterine fibroid, or even cervical cancer.
Cervical cancer is the most serious cause of this post-coital bleeding. Fortunately, this illness is becoming less and less common. This is due to the fact that women are going to gynecological check-ups more frequently.
In addition, many studies have shown that there’s a link between cervical cancer and the human papilloma virus. That’s why, nowadays, thanks to the vaccine against this virus, the number of women with this tumor has also been reduced.

How can it be diagnosed?
As we’ve just mentioned, the causes of post-coital bleeding can range from easily treatable dryness to a more serious problem, such as cervical cancer. Therefore, it’s important to visit a professional to get the correct diagnosis of the cause of this bleeding.
First of all, you need to know how to identify whether the bleeding is post-coital or not, and to differentiate it from a possible menstruation. Likewise, it’s essential to check that there aren’t any lesions in the area that may be causing the blood, such as a small tear.
The gynecologist will perform an examination of the entire area. In addition, complementary tests, such as a Pap smear and a culture, are usually ordered. Thus, infections or cancer can be ruled out.
On the other hand, to reach a diagnosis on the causes of post-coital bleeding, you have to explain the whole situation to your doctor, mentioning if you have any other underlying disease or if you take any medication.
