What is the normal rate of sperm motility? This is a topic that many male friends are concerned about, and authoritative experts on Sperm 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 is considered to be low sperm motility.
Within one hour after ejaculation, the proportion of active sperms should be over 70%. If the active sperm is less than 50%, it is considered abnormal, known as low sperm motility or asthenozoospermia. If there is no movement at all in the sperm, it's called dead sperm syndrome. Low sperm motility and dead sperm syndrome are important causes of male infertility.
Causes include:
1. Long-term abstinence: Often, high sperm density, more dead sperm, and poor sperm motility are observed in men who have not ejaculated for a long time. This situation is considered normal, so it is recommended to abstain from sexual activity for 5-7 days before semen examination.
2. Reproductive system infection: Infection can alter the components of seminal plasma, reduce zinc, magnesium, citric acid, fructose, and increase pH, all of which can affect sperm vitality.
3. Varicocele: Due to blood circulation disorders in the testes and epididymis, local temperature rise, accumulation of toxic substances, sperm motility decreases. It is suggested to go to the hospital for a clear diagnosis so that timely symptomatic treatment can be provided.
Normal semen is viscous, milky white, containing gray-white clots, which liquefy on their own after about 10-20 minutes, turning into semi-transparent, turbid thin mucus. Sperm motility is divided into four levels: Level A indicates excellent sperm activity with rapid straight-line forward motion; Level B indicates good sperm activity with straight-line forward motion; Level C indicates average sperm activity with only curved forward motion; Level D indicates poor sperm activity, only wriggling in place. The sum of rapidly forward-moving sperm (Level A) and slightly slower forward-moving sperm (Level B), if less than 50% or Level A sperm less than 25%, is considered weak sperm.
