What is the normal value of sperm motility?

Sperm vitality is an issue that every male friend is concerned about. In our daily life, we need to pay attention to the health of our diet, which is very important for the vitality of our sperm. Our work and rest habits are also very important. Taking good care of your physical health is very important, which will be beneficial to the growth of your next generation.

Generally, infertility requires semen analysis to rule out male factors. Common test items include abstinence time, total semen volume, color, pH value, density, motility, activity, deformity rate, etc.

The best abstinence period is 1-7 days, shorter rather than longer. Because sperm is stored in the epididymis after production, it will be ejaculated if there is sexual intercourse. Long-term storage will destroy and reabsorb it. Fresh semen is representative. On the contrary, if it exceeds 7 days, sperm stays in the epididymis for a long time, dead sperm increases, and is not representative. For example, the semen of monks and lamas is often abnormal.

The total volume of semen is 2-5ml for normal people; the color is grayish white, and it will turn yellow if the abstinence period is long; the pH value is 7.35-7.45; the density is more than 20 million/ml; the motility is divided into four levels: a, b, c, and d. Those who move in a straight line are level a, those who move in a curve are level b, those who spin in place are level c, and those who do not move are level d. For normal people, levels a and b should account for more than 40%; the deformity rate is that the number of deformed sperm should not exceed 30%.

There are several misconceptions when reading a semen test report.

First, the liquefaction time. Textbooks describe the normal liquefaction time as 30 minutes. In the past, it was believed that long liquefaction time or no liquefaction would lead to infertility. Modern research has denied this view, because the semen does not liquefy or takes a long time to liquefy in an environment outside the vagina is a protective mechanism. Such a man can generally get pregnant if the woman is normal. To determine that the non-liquefaction is the cause of infertility, a copulation test must be performed for further examination, that is, after two hours of normal sexual intercourse, the cervical mucus is taken to detect the number of live sperm.

Second, low sperm motility. Sperm is most active between 32 and 37 degrees. If the temperature is lower than this, the motility will decrease. Some hospitals ask patients to go to the toilet to collect semen. If it is winter, the semen is ejaculated into a container with a lower temperature. If the microscope is not equipped with a heating table, a small amount of semen is placed on a cold glass slide and tested under the microscope, it will appear that the motility is low. Our hospital has a quiet, warm and cozy semen collection room. The microscope is equipped with a 37-degree constant temperature table. Many patients with low sperm motility (weak sperm) from other hospitals are normal when they come to our hospital for examination. Facts have proved that the cause of infertility is mostly female.

Treatment of semen abnormalities

Oligospermia can be diagnosed when the sperm density is less than 20 million/ml for two consecutive tests. If the oligospermia is between 2 million and 20 million, a child can be obtained through artificial insemination. The semen ejaculated multiple times is frozen in liquid nitrogen. After the woman's ovulation is induced and the follicles mature, the frozen semen is taken out once, dissolved, and screened to obtain the same sperm density as a normal person. Such semen is sent into the woman's uterus and fallopian tube to successfully conceive; if it is below 2 million/ml, it is necessary to use the technology of single sperm injection to obtain a child, that is, the woman induces ovulation, takes out the follicles after maturity, and uses a micromanipulator to inject a single sperm into the egg for forced fertilization, which can also achieve the purpose of pregnancy. However, the offspring born through this assisted reproductive method, if they are male, often still have oligospermia.

Azoospermia means that sperm cannot be seen under a microscope. There are two clinical categories. One is obstructive azoospermia, which means that the testicles can produce sperm, but azoospermia occurs due to blockage of the vas deferens. The other is true azoospermia, which means that the testicles have no spermatogenic cells and cannot produce sperm. Obstructive azoospermia can be treated by testicular puncture to obtain sperm for single sperm injection to conceive a child. True azoospermia can only be treated by artificial insemination with other sperm

The above is about the normal value of sperm motility. I hope it will be helpful to everyone. What we need to do is to change ourselves so that our bodies can live better and healthier. The number of sperm in men is more than that in women, but the quality also needs to be taken seriously so that we can better protect our own health.
