1. Abnormal semen osmotic pressure, normal male semen osmotic pressure is (356.17 ± 32.12) MOSM/KG H2O.When the sperm's vitality increases when the semen osmotic pressure is slightly lower, the sperm vitality decreases when the permeability pressure is high, and the sperm tail deformity occurs when it is too high.The osmotic pressure often depends on the function of the auxiliary glands. When the auxiliary glands are abnormal, the semen osmotic pressure will change.
2. Excisible semen, more than 6 ml of semen is polyzenis, less than 2 ml is young sperm, and less than 0.5 ml is non -sperm.Different sperm density is reduced due to excessive semen; spermatic disease is more common in retrograde ejaculation and non -ejaculation.
3. The color, odor, viscosity and liquefaction time of semen, normal semen is milky white or gray -white, semen transparent may be young sperm or no sperm, semen is pink, dark red may be blood sperm.When the scent is heavy, it is prompted to have semen infection.Increased semen viscosity will affect the ability of sperm penetration of cervical mucus and lead to infertility.The viscosity of semen is regulated by the condensation factor secreted by the seminal sac and the liquefied factors secreted by the prostate. When the liquefied factor and the coagulation homology are balanced, the semen shows liquefaction abnormalities.Common and congenital seminal vessels are dysplasia.
4. Extraction of semen, neutral alkaline semen is the most suitable external environment for sperm activity. When the pH value of the semen changes, it can affect the vitality, survival rate and metabolic rate of sperm.When prostate and seminal vesicles are inflammatory, the pH value often changes.
5. The biochemical of the sperm, when the composition of the sperm pulp changes, will definitely affect the function of sperm.The biochemical ingredients in sperm pulp can often be used as indicators to judge the rigidity gland function, such as acidic phosphatase, citric acid, zinc, and magnesium can be used as indicators for prostate function; fructose and prostaglandin are indicators of semen function; botoxine, glycoside, glycoside, glycoside, glycoside, glycosideEnzymes and glycerol phosphate are indicators for epididymal function.
6. White blood cells in semen, self -cell density in normal semen is less than 1 × 106/ml.When the increase in white blood cells in semen can lead to a decrease in exercise and activity rate, and damage to the integrity of sperm membrane, thereby reducing sperm fertilization.Studies have found that the increase in white blood cells in semen is also the reason why the special sperm vitality is low.
