If intercourse is conducted with a condom or through withdrawal, it becomes easier to detect hematospermia. When people suddenly notice a change in the color of their semen, they often become anxious and worry about what is happening.

Hematospermia should not be taken lightly, as it could also be a sign of a serious disease. It is best to consult a specialist doctor for a thorough examination. Clinically, hematospermia is not uncommon. After detailed clinical and laboratory tests, the majority of cases can be controlled or cured through treatment, with only a small number of tumor patients requiring further treatment.
The composition of semen consists mainly of a small volume of sperm, with the rest coming from the seminal vesicles, followed by the prostate. Anatomically, the ejaculatory ducts connecting the seminal vesicles open into the posterior urethral crest, surrounded by 10–20 openings of prostatic ducts. In fact, the seminal vesicles, prostate, and posterior urethra are interconnected, and inflammation can easily spread from one to the others. Additionally, the wall of the seminal vesicle is very thin, and once it becomes congested
