The presence of hematosperm in male patients refers to the presence of blood in the semen, which appears as red or bright red semen. There are numerous causes of hematospermia, which can be seen in diseases such as inflammation of the seminal vesicles and seminal caruncle, inflammation of the urethra or tumors of the seminal vesicles, etc. Detailed examination is needed to clarify what causes it. The most common causes: 1, infection of the seminal tract, such as seminal vesiculitis, vesiculitis, vasovaginitis, inflammation can lead to local congestion, blood mixed with semen, in the process of ejaculation can appear ejaculatory pain and hematemesis, it is recommended to do further urethroscopy and CT, to understand whether there is inflammation of the seminal vesicle seminal tract. 2, seminal tract stones, secondary to chronic seminal tract infection, can form a stone change resulting in repeated bleeding. Further vesiculoscopy is needed, which can play a dual role of diagnosis and treatment. When stones in the seminal vesicles and seminal tract are found, they can be removed by flushing under seminoscopy, and antibiotic infusion can be used to treat the infection. 3. Tumors of the seminal vesicles, such as prostate cancer metastasizing to the seminal vesicles or primary tumors of the seminal vesicles, may cause bleeding due to destruction of the seminal vesicles themselves, followed by hematospermia. Further CT of the seminal vesicle is needed to identify the tumor, and if the tumor of the seminal vesicle is confirmed, surgery is needed to remove it.
