Not, man bleeding during or after intercourse it is not normal. Bleeding during ejaculation or the presence of blood on sperm usually caused by inflammations, infections and traumas.
Most of the time, it is a condition benign and self-limiting. In addition, bleed frequently during or after intercourse or if the bleeding is accompanied by other symptoms, it may be a sign of something more serious, such as cancer, especially in older men.
The main causes gives presence of blood in sperm are:
- Inflammation or infection: It is the most common cause in men under the age of 40. Inflammatory processes cause mucosal irritation, increased blood flow and swelling of ducts and glands, resulting in bleeding;
- Trauma or injury caused by medical procedures: Prostate biopsy is the main cause in these cases, with bleeding seen in up to 85% of men. Other causes include:
- brachytherapy to treat prostate cancer;
- presence of foreign body;
- perineal traumas (area between anus and penis) or genital tract;
- fracture of the penis;
- fracture of the basin.
- Cysts: They can compress very small blood vessels, blocking blood flow at some points. Ejaculation relieves this pressure, leading to a distension of the vessels resulting in bleeding;
- Tumors: There are several benign tumors that can cause a man to bleed during or after intercourse because of the new vessels that are formed in the tumor. Malignant tumors of the prostate, seminal vesicle and testis are rare causes of blood in the semen, accounting for about 4% of bleeding in men over 40;
- Other causes of bleeding:
- Vascular abnormalities (varicose veins in seminal vesicles, prostatic urethra, arteriovenous malformations, hemangioma in the prostate);
- Lymphoma;
- Von Willebrand disease;
- Hemophilia;
- Blood clotting disorders;
- Use of medications.
- Arterial hypertension.
Despite the anxiety that bleeding can generate in man, it is usually nothing serious and often has an unknown cause.
However, as stated at the outset, if the bleeding or the presence of blood on sperm are recurrent or are associated with other symptoms, it is important to consult the
urologist, family doctor or general practitioner for a more thorough investigation.
