Four common reasons for blood in men's semen

Many male friends around me have a question: why is there blood in their semen after ejaculation? Let's follow the andrology expert to find out, hoping to answer your doubts.

1. Inflammation:

The seminal vesicles, prostate glands, urinary tract, rectum and other organs are closely adjacent to each other, which can easily lead to infection. The post-infection inflammatory process can stimulate the tubules and glandular mucosa, causing local congestion, edema and bleeding. Infection pathogens include viruses, bacteria, mycobacteria and parasites. Inflammation can also be the result of trauma, foreign bodies in the urethra, and chemicals. Trauma can include stones in the prostate or seminal vesicles.

2. Obstruction or cyst:

Ejaculatory duct obstruction can cause the proximal end of the obstruction to dilate and swell, leading to mucosal vascular rupture and bleeding, such as Wolffian duct cysts, seminal vesicle cysts and prostate cysts.

3. Tumor:

It has been reported that various benign tumors can cause hematospermia, such as ectopic prostate tissue in the urethra, prostate polyps and hyperplastic urine, etc. Malignant tumors of the prostate, testicles and seminal vesicles can cause hematospermia.

4. Vascular abnormalities:

Varicose veins of the seminal vesicle, prostatic urethra, and bladder neck can also be the cause of hematospermia. In addition, vascular abnormalities of the reproductive system during puberty can cause hematospermia, including arteriovenous malformations, prostatic hemangiomas, seminal vesicles, and rare spermatic cord hemangiomas.
