What causes low sperm motility?

When you go to the hospital for a pre-pregnancy check-up, or when some couples cannot conceive normally for a long time, you will find through the examination that the man’s sperm motility is relatively low, which is an important reason for not being able to conceive. To address this problem, men must first improve their living habits, eat more foods rich in zinc and magnesium, and eat more foods rich in pigments, etc., which are all helpful for improving sperm motility. So what are the reasons for the decline in men’s sperm motility?

What causes low sperm motility?

Low sperm motility may be caused by some inappropriate lifestyle before marriage, such as alcoholism. Alcoholism is very harmful to sperm and may also cause sperm deformity. In addition to alcoholism, smoking can also lead to weak sperm. If it is a reproductive system infection, the composition of semen will change, zinc, magnesium, citric acid, and fructose will decrease, and the pH will increase. This series of changes will affect the motility of sperm.

In fact, many small things in life will cause low sperm motility if not handled properly. For example, wearing tight underwear frequently, driving frequently, facing the computer for a long time, taking a hot bath, and taking a sauna will increase the body temperature of men, which will affect the development of sperm. If the temperature of the scrotum is not in the range of 35-36℃, especially when the temperature is high, it will cause poor sperm development and naturally low sperm motility, which may affect fertility.

Avoid smoking, drinking, and eating too much meat and fish in your daily life and exercise appropriately. For IT men or programmers, the probability of low sperm motility is even higher. They often face computers and stare at mobile phones. These radiations will also make sperms dizzy and reduce sperm motility.

What is the normal value of sperm motility?

The symptoms of low sperm motility were explained at the beginning of the article. They do not move in a straight line but in a curved line. Some even go on strike and go in circles. But what is the normal sperm motility? If the sperm motility rate is less than 29%, it is below the normal standard.

Generally speaking, after AA, of the tens of thousands of sperms ejaculated, 60% should be heading for the egg in the first hour, and no less than 50% in the second hour. Only when all the sperms are moving and run fast can they be the first to have sex with the egg.

If the sperm motility is not enough, it will be difficult to become a father. In terms of sperm motility, some men have azoospermia, some have oligospermia, and the majority have asthenospermia, which means low sperm motility.

In fact, sperm motility is also divided into several levels, A, B and C. A means that the sperm has good motility and can move in a straight line; B means that the sperm has average motility and can only move forward in a curved line; C means that the sperm has poor motility and can only move in circles. Low sperm motility is a symptom in which less than 50% of the sperm in the semen parameters move forward or less than 25% of the sperm in A level movement.
