The proportion of immature sperm in summer is higher than other seasons. This is because of the hotness.The hot weather causes the sperm vitality and has a long -term men's infertility.So, how do we check whether sperm vitality is normal?
What are the sperm vitality standards?
I. Elimination of semen: The amount of normal semen is 2 to 6 ml. If the amount of sperm is greater than 6 ml, it is considered to be too much semen.The amount of sperm is less than 1.0 ml, and it is considered that the amount of semen is too small.The amount of semen is related to the length of abstinence.For abstinence, the amount of semen is more, otherwise less.Therefore, usually when we do semen examination, we will be told that the disease must be separated from the interval between 4 to 5 days and then take the semen, so that the results of the examination are relatively accurate.
Second, the sperm appearance: The newly ejected semen is jelly -like, gray -white or gray -yellow.When semen liquefies, it is translucent milky white or milky yellow.For a long time, the semen has a deeper color.The semen of the elderly is mostly dark yellow.
Third, the smell of semen: Normal semen has a special smell. Some people are compared with chestnut flower flavor, and some people describe the flavor of poppy.This odor is due to the oxidation of the prostate fluid.The longer the ascetic time, the greater the smell.
Fourth, semen liquefaction time: The liquefaction of semen is the process of changing from jelly to liquid -like after the semen is ejected.Normal semen liquefaction time is 30 minutes.If it is more than 30 minutes, it is not liquefied or liquefied in the semen.
5. Semen viscosity: After the liquefied semen is liquefied, there is a sticky liquid. Use a straw to stick the semen to the sperm naturally. If the semen is discontinuous, dripping a drop, the viscosity is normal.If there is a long (2 cm) mucus, it is too much viscosity.Semen does not liquefy, liquefaction incompleteness, or excessive viscosity, which will affect the movement of sperm and cause infertility.
6. Semen acidity and alkali: The pH value of normal semen is 7.2 to 8.0, and less than 7.2 or greater than 8.0 is abnormal.It is worth noting that the semen should be checked immediately after liquefaction. The specimen is too long, which will affect the result of the pH value of the semen.
Seven, sperm count: The number of sperm for normal fertility is 20 million/ml.After many inspection of the sperm, the sperm is less than 20 million/ml, it is a young sperm disease.The sperm number is greater than 250 million/ml, which is multi -sperm.Excessive sperm count or too little can affect fertility.
8. Sperm activity rate: Sperm activity rate refers to the sperm ratio surviving in semen.Normal sperm activity & ge; 75%.
Nine, sperm activity: sperm activity refers to the ability of sperm activity. Generally, sperm activity is divided into five levels: Class A, sperm line quickly move forward; level B, sperm slowly move forward; C -level, no, no, none of themTreatment of directional exercise; D -level, sperm movement; E -level, sperm motionless.The activity of normal sperm should be, within 60 minutes of ejaculation, A -level+B -level & GE; 50%, or A -level & Ge; 25%.
X. Sperm form: 50%of the sperm of normal form, no more than 40%of the deformity sperm.If this criterion is more deformed sperm, it is one of the causes of male infertility.
11. Number of white blood cells in semen: The number of white blood cells in normal semen "1 × 106/ml, that is, the number of white blood cells per high -power field of view should be less than 10.If more than 20 of them should be considered as pustular.
How to maintain normal sperm vitality?
1. Fitness exercise every day, it is recommended to run in the morning.
2. In terms of dietary habits, quit smoking and drinking, eat more fruits in the morning, mainly food made of wheat raw materials, such as bread oatmeal drinks are mainly fresh milk.The most fried food.
3. Stay away from radiation from the working environment. Do not put your mobile phone in your pants pocket. The phone has radiation.
