The sperm survival rate can reach 70% within one hour, which can be divided into four grades. It is considered that the sperm survival rate is normal. One hour after sperm discharge, the number of live sperm should be greater than 70%. If the motile sperm is less than 50%, it is abnormal. Sperm is the key to a man's conception. The main reason why many men can't have children is that sperm quality is not up to standard, male sperm vitality is insufficient, nutrition is insufficient, pH value changes, adnexal gland and vas deferens infection can all affect sperm survival rate.
Extended data:
There are three main reasons for the survival rate of male sperm:
1. Reproductive tract infection: Reproductive system infection causes changes of zinc, magnesium, citric acid, fructose and pH value in seminal plasma, which affects sperm movement.
2, long-term abstinence: long-term non-ejaculation usually has high sperm density, more sperm and low sperm activity, which is normal, so it takes 5-7 days to check semen before abstinence check.
3, varicocele varicocele: due to the disorder of blood circulation in testis and epididymis, local temperature rises, toxic substances accumulate, reducing sperm motility. The survival rate of normal sperm should be above 60%, but due to radiation, some drugs, inflammation and other factors, the quality of sperm is seriously reduced.
