1, the method of judgment
2-6 ml of normal semen just injected is viscous and milky white, containing grayish white clots. After about 10-20 minutes, the clot will liquefy itself and become translucent, turbid and thin mucus. The smell of semen is produced by arginine secreted by prostate in semen, which is a unique fishy smell. The normal sperm motility rate is above 70%, the B(A +B) of A-grade and slightly slower sperm is 50% or the A-grade sperm is 25%. The deformity rate is 25%, with 0-5 white blood cells.
Semen quality analysis is difficult to identify with naked eyes and can be judged by instrument testing.
Whether there is sperm in semen can go to a regular hospital for routine semen examination, and you can know sperm density, total sperm count, sperm viability, sperm vitality and so on.
Suggestion: In addition, long-term irregular life, smoking and drinking may lead to the decline of sperm viability and vitality, which will have some impact on fertility.
2. Biochemical examination of seminal plasma
Seminal plasma is the medium of sperm, which is responsible for providing nutrition for sperm and assisting sperm to reach the fertilization site. Various biochemical components in seminal plasma are secreted by specific accessory gonads. Through quantitative detection of various components, we can judge whether the seminal plasma is normal or not and the source of the disease. The main substances secreted by each gonad include:
1. Prostate
Zinc: Zinc is a coenzyme of many enzymes in human body and participates in many metabolic activities. Prostate is one of the organs with the largest zinc content in the body. The content of zinc in normal human seminal plasma is 100 times that of plasma, which reflects that zinc is very important to maintain sperm function, but the specific mechanism is still unclear. The normal value of zinc in seminal plasma is one ejaculation ≥2.4μmol, indicating that prostate function is impaired.
Acid phosphatase: catalyzes the hydrolysis of phosphate bonds and exists in all tissues of the body, especially the prostate. The content of acid phosphatase in seminal plasma can be used as an index to diagnose prostate lesions, but the relationship between its level and sperm quality is still unclear. The normal value of acid phosphatase in seminal plasma is one ejaculation ≥ 200 u.
Citric acid: The content of citric acid in seminal plasma is relatively high, almost all of which comes from prostate. Its function is to adjust osmotic pressure and complex calcium ions, and influence the coagulation and liquefaction process of semen by changing the concentration of calcium ions. The normal value is one ejaculation ≥ 10μmol.
2.seminal vesicle
Fructose: Fructose in seminal plasma provides energy for sperm and maintains sperm activity. At the same time, it is parallel to androgen, which can indirectly reflect the blood testosterone level and can be used to detect the function of seminal vesicle and leydig cells. Normal level ejaculation ≥ 13μmol.
Prostaglandins: Studies have shown that prostaglandins in seminal plasma can improve sperm motility and inhibit the immune attack of female reproductive tract. Its content is difficult to detect and be adopted by clinical institutions.
3. Epididymis
Neutral glycosidase: The specific marker enzyme of epididymis, whose change indirectly reflects the change of epididymal function, and also means that the maturation of sperm in epididymis is affected. Its normal value is one ejaculation ≥20mU.
