Is male semen not sticky and normal? Several values for judging whether semen is normal
How can male semen be normal? Everyone must know the importance of semen for male friends. Many male friends do not know how semen is normal. Let's introduce how male semen is normal.
Semen status is an important basis for men to judge their own reproductive and sexual abilities. But what should normal semen look like? What problems do the different changes of semen reflect?
According to the regulations of the World Health Organization, men can judge from the following four points:
Semen volume: the normal volume should be more than or equal to 2ml (ml). If it is more than 7ml, it is too much. At this time, not only the sperm density becomes low, but also it is easy to flow out of the female vagina, resulting in a decrease in the total number of sperm, which is common in patients with seminal vesiculitis. If the total amount is less than 2ml, it means that the amount of semen is small, and if the total amount is less than 1ml, it means that the amount of semen is too small, which is easy to cause infertility.
Color: The normal color is gray white or slightly yellow. If the semen appears milky white or yellow-green, it indicates that there is inflammation in the male reproductive tract or accessory gonads. If there is pink, red, or red blood cells can be seen under the microscope, it is bloody semen, which is common in patients with paragonads and post-urethritis, and occasionally in patients with tuberculosis or tumor.
PH: the normal ph value of semen is 7.2~7.8. Less than 7.2 can be seen in ejaculatory duct obstruction or urine contamination; More than 7.8 can be seen in seminal vesicle inflammation or obsolete specimens.
Liquefaction time: after normal semen is ejaculated, it becomes gelatinous under the action of seminal vesicle coagulase, and becomes liquid under the action of prostate liquefaction enzyme after 15-30 minutes, which is semen liquefaction. It is abnormal that semen does not liquefy 30 minutes after ejaculation.
Viscosity: contact the glass rod with the liquefied semen and gently lift it to form semen silk, which is normally less than 2 cm in length.
Sperm count: generally expressed by the number of sperm per milliliter of semen. Normal count ≥ 20 × 10? 6/ml。 Below this value, there are too few sperm, which can be seen in spermatogenic dysfunction caused by various reasons, and can lead to low fertility or infertility due to the reduced chance of sperm entering the uterine cavity and fallopian tube. If sperm count is greater than 250 × 10? 6/ml refers to excessive sperm, which can also lead to infertility due to the influence of its activity.
Sperm morphology: sperm with normal morphology ≥ 50%, otherwise it may cause infertility.
