Blood semen

Introduction Blood essence is also called blood. Normal semen excreted in vitro is milky white. If it is observed by the naked eye that the discharged semen is pink or red, it is called blood essence, also called "eye blood sperm". This is a serious disease. The mild blood sperm can not be found by the naked eye. Microscopic examination revealed semen to red blood cells, called "microscopic blood."

Cause

Causes of blood sperm

The most common cause of blood sperm is seminal vesiculitis, the seminal vesicle is a storage sperm, and the second is the seminal vesicle fluid. The seminal vesicle is rich in tiny blood vessel layers. It contains many microvessels, which are easily damaged and hemorrhage. At the same time, because the seminal vesicle is located on the prostate. Between the bladder rectum, the end of the bladder and the vas deferens form an ejaculation and lead to the urethra. Because the seminal vesicle is adjacent to the prostate, urinary tract, rectum and other organs, if inflammation occurs in these parts, the bacteria can easily spread to the seminal vesicle, causing inflammation of the seminal vesicle and swelling of the seminal vesicle. , congestion and bleeding, and cause blood, most accompanied by perineal, rectal and lower abdominal pain or dysuria.

Blood test

If an adult man has to undergo sexual intercourse or spermatorrhea for a longer period of time (several months), the semen from which it is shot tends to be thick, and the color of the semen is yellowish. For example, when ejaculation is accompanied by less abdominal or perineal discomfort or pain, it is necessary to pay attention. Identification with blood.

Check: Microscopically, the semen contains a lot of red blood cells, which can also confirm the disease.

Clinical laboratory tests: When collecting secretion samples, pay attention to the relationship between the compression area of the rectal examination and the secretions. Massage the prostate to collect the prostatic fluid, then massage the left and right seminal vesicles separately after urination, and collect the seminal vesicles. The differential diagnosis of the two. If necessary, a seminal vesicle angiography can be performed to confirm the diagnosis. Laboratory tests revealed large numbers of red blood cells in the semen.

Differential diagnosis

In the case of sexual intercourse or masturbation or nocturnal emission, the semen containing blood is injected, or the microscope is found to contain a large amount of red blood cells in the semen, which can be diagnosed as the disease.

Bloody confusing symptoms

The route of infection, etiology, clinical manifestations and symptoms of seminal vesiculitis and prostatitis are basically similar. Mostly bacterial infections, but also due to excessive frequency of sexual intercourse or long-term abstinence, sexual tension can not be released resulting in organ congestion. Seminal cystitis is mainly characterized by sexual intercourse with blood, accompanied by symptoms such as decreased sexual desire, premature ejaculation, mild perineal pain or bulging, ejaculation pain, frequent urination and dysuria. Prostatitis is also accompanied by urinary burning sensation, urgency, urinary dripping or post-urinary urethra with milky white mucus outflow, no localized pain, and even sexual dysfunction such as premature ejaculation, nocturnal emission, erectile dysfunction.

Due to their complex anatomical structure, poor drainage, it is easy to turn chronic, which causes secondary vas deferens obstruction, ejaculation edema obstruction, resulting in dry ejaculation with only ejaculation action but no semen discharge. This is the mechanism by which blood sperm causes infertility. Other causes of infertility include changes in seminal plasma components in seminal vesiculitis, bacterial engulfment of nutrients in seminal plasma, competition for oxygen, and excretion of toxins and metabolites, undoubtedly putting sperm in an extremely unfavorable environment with reduced fertility; inflammation When the seminal plasma acid is increased, the pH of the semen is reduced from the alkaline 7.2-8.9 which is suitable for sperm survival, to the minimum survival requirement of 6-6.5, and the sperm will lose its fertility early; Because there are a lot of cells and a lot of white blood cells in the seminal plasma, it may also contain pus, the viscosity will increase significantly, the injected semen will not be easy to liquefy, the sperm can't move and can't drive straight into the cervix. The volume of seminal plasma in inflammation is too small, which is not conducive to sperm survival; too much, so that sperm dilution is not conducive to fertility. Of course, these analyses are only superficial. In fact, many links or reasons are not clear. People still have to study and discuss them, because many patients have mild inflammation but have not affected fertility. Of course, if the ejaculatory duct is blocked for a long time, it is possible to produce anti-sperm antibodies in the body like the vasectomy, and the problem is further complicated.

The seminal vesicle cyst usually has no obvious symptoms and belongs to congenital lesions. In the secondary seminal vesiculitis, there may be blood sperm, easy to recurrent, cysts too large can also oppress the bladder urethra caused by poor urination. For patients with blood essence who are more difficult to cure, if a radiograph is taken by percutaneous transluminal injection of contrast medium, a cystic mass with a smooth inner wall can be found in the seminal vesicle. B-mode ultrasound can detect cystic masses. After the angiography, the antibiotic can be directly injected into the sac through the catheter. If it is invalid, the cyst can be surgically removed. Seminal vesicle tumors are rare. B-mode ultrasound examination is solid. The seminal vesicle gland angiography shows that the tumor occupies a space filled with contrast agent filling defect. At this time, the tumor should be surgically removed.

Due to the difference in bleeding site and blood volume, the appearance of blood sperm is also different: the blood from the urethral mucosa that is congested from erection is bright red, not mixed with semen, like mixed bloodshot. The blood and fines caused by various inflammations and traumas are evenly mixed, ranging from red to brown, due to changes in the color of the blood stored for a long time. Since the semen stored in the seminal vesicles can be emptied without a ejaculation, even if it is timely and adequately treated, the blood sera will not disappear until a certain period of time.
