What is considered normal for male semen? We all need to know the importance of semen to male friends. Many male friends do not know how semen is normal. Let's introduce how male semen is considered normal.
The condition of semen is an important basis for men to judge their reproductive and sexual abilities. But what should normal semen look like? What issues do the different changes in semen reflect?
According to the regulations of the World Health Organization, if semen is normal or abnormal, men can independently determine the following four points:
Semen volume: The normal volume should be greater than or equal to 2ml (milliliters). If it exceeds 7. At this point, the sperm density not only decreases, but also tends 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 of semen is less than 2ml and the amount is too small below 1ml, it can easily lead to infertility.
Color: The normal color is gray or slightly yellow. If the semen is milky white or yellowish green, it indicates inflammation of the male reproductive tract or accessory gonads. If red blood cells appear pink or microscopic, it is blood semen, which is commonly seen 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 to 7.8. Less than 7.2. Ejaculatory duct obstruction or urine contamination greater than 7.8. Seminal vesicle inflammation or old specimen.
Liquefaction time: After normal ejaculation, semen becomes gelatinous under the action of seminal vesicle coagulase, and becomes liquid within 15 to 30 minutes under the action of prostate liquefaction enzyme, which means semen liquefaction. It is abnormal for semen to remain non liquefied 30 minutes after injection.
Viscosity: When Glass rod contacts with liquefied semen, it can be gently lifted to form semen filament, and the normal length is less than 2 cm.
Sperm count: Generally expressed as the number of sperm per milliliter of semen. Normal count 20x10? 6/ml. Below this value, there are too few sperm, which can be seen in the 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 the sperm count is greater than 250x10? 6/ml can also lead to infertility due to excessive sperm count and its impact on survival.
Sperm morphology: Normal morphology of sperm 50%, otherwise it may cause infertility.
Activity: Sperm moves forward rapidly in a straight line, athlete 50%.
Survival rate: Generally refers to the examination within 1 hour after ejaculation, with 50% of live sperm. Paraadenitis, Varicocele, ciliary dullness syndrome caused by chronic respiratory infection, antisperm antibodies in semen or improper storage of samples are common reasons for the decline of sperm activity and survival rate.
