What is the normal sperm motility rate? This is a topic of concern for many male friends, and authoritative experts on Sperm and Egg Network (http://www.r85.net/) point out that generally, a sperm survival rate reaching 60%-70% is considered normal. If the sperm survival rate is below this value, it falls under low sperm survival rate.
Regarding what is the normal sperm motility rate, within one hour after ejaculation, the proportion of active sperm should be over 70%. If the active sperm count is below 50%, it is considered abnormal, known as low sperm motility or asthenospermia. If there is absolutely no sperm activity, it is called necrospermia. Low sperm motility and necrospermia are important causes of male infertility.
Causes include:
1. Long-term abstinence, often leading to high sperm density, more dead sperm, and poor sperm motility. This situation is considered normal, so it is advisable to abstain from sex for 5-7 days before semen analysis.
2. Reproductive system infection, which alters the composition of seminal plasma, reducing zinc, magnesium, citric acid, and fructose levels while increasing pH, all affecting sperm vitality.
3. Varicocele, due to impaired blood circulation in the testes and epididymis, increased local temperature, and accumulation of toxic substances, resulting in low sperm motility. It is recommended to visit a hospital for a clear diagnosis and timely treatment.
Normal semen is viscous, milky white, with grayish-white clots that liquefy on their own about 10-20 minutes later, turning into a semi-transparent, cloudy thin mucus. Sperm motility is divided into four levels: Level A indicates excellent sperm activity, moving forward rapidly in a straight line; Level B indicates good sperm activity, moving forward in a straight line; Level C indicates average sperm activity, moving forward in a curved path; Level D indicates poor sperm activity, only wriggling in place. If the sum of rapidly forward-moving sperm (Level A) and slightly slower forward-moving sperm (Level B) is less than 50%, or if Level A sperm is less than 25%, it is considered asthenospermia.
