Hemosperm is the presence of blood mixed with semen when the patient ejaculates. There are several forms of manifestations: i. If the hemosperm is caused by inflammation or other reasons, such as through urethral surgery, the semen and blood are usually mixed more evenly. Second, if the bleeding comes from the mucosa of the urethra or the bladder, it may manifest itself as bright red blood mixed in the semen, which does not mix well with the semen. III. If the bleeding is in origin from the seminal vesicles, the bleeding is prolonged and often appears coffee-colored. IV. If the bleeding is fresh and the blood is pink in color, it may manifest as initial hematospermia, terminal hematospermia and total hematospermia. The most common causes of hematosperm include: 1. inflammation of the genitourinary system, such as vesiculitis or prostatitis. 2. tumors of the urinary system, such as tumors of the posterior urethra or bladder tumors, especially those close to the bladder neck, can also present hematosperm. 3. varicose veins caused by hyperplasia of the seminal vesicles and bladder neck and prostate gland, with ruptured blood vessels and bleeding, can also present hematosperm. 4. obstruction of the ejaculatory ducts, such as The ejaculatory ducts are lined with stones or tumors, and cysts in the ejaculatory ducts can lead to hematospermia. 5. Systemic diseases, such as systemic coagulation dysfunction, can lead to local vascular rupture and hematospermia during ejaculation. These are some of the common causes, and for more details, patients should preferably go to the hospital for a checkup after the appearance of hematospermia.
