Do you know what is normal sperm motility rate?

In recent years, more and more men have been troubled by semen abnormalities. The causes of semen abnormalities may be a variety of factors such as low sperm count and low sperm motility. The following article mainly introduces the sperm motility problem and sees what the normal range of sperm motility is.

What is the normal sperm motility rate?

Normal values ​​of semen are: semen volume (2-6 ml), semen pH (7.2-7.8), semen liquefaction time (20 minutes for complete liquefaction), sperm count (20 million-200 million/ml), sperm motility (quantification of forward-moving sperm, no less than 60% in the first hour, 2-3

hours not less than 50%), sperm survival rate (dead sperm not more than 50%), easy to conceive.

Causes of low sperm motility

1. Long-term abstinence. Long-term non-ejaculation often results in high sperm density, many dead sperm, and poor sperm motility. This is normal, so it is advisable to abstain from sex for 5 to 7 days before checking semen.

2. Reproductive system infection. Reproductive system infection changes the composition of seminal plasma. The decrease of zinc, magnesium, citric acid, and fructose and the increase of pH will affect sperm motility.

3. Varicose vein: due to the obstruction of blood circulation in the testicles and epididymis, the local temperature rises, toxic substances accumulate, and sperm motility decreases.
