Can men with asthenospermia have children?

The first major problem that couples face when they get married is pregnancy and childbirth. However, having a child is not such a simple matter. Many couples are indeed troubled by pregnancy. After preparing for a long time and trying many times, they still cannot get pregnant, which still makes people feel disappointed. There are many reasons for not being able to get pregnant, including the body of men and women. So, can men with asthenospermia have children?

Among the infertile army, a certain proportion of men suffer from asthenozoospermia. Improving sperm motility and having a baby of their own is the common wish of patients. Asthenozoospermia actually refers to low sperm motility. Under normal circumstances, a certain proportion of sperm should move forward and have the ability to move forward quickly (this ability is obtained when passing through the epididymis). If this ability is lacking, it may lead to male infertility. The probability of this infertility is often proportional to the degree of sperm motility.

Under normal circumstances, after sperm matures, it needs the help of various active substances secreted by the accessory glands to further obtain energy to maintain its ability to continue to move forward. Some reproductive scientists point out that if the epididymis and other organs and accessory glands have infectious diseases, immune diseases, diseases related to the function and development of the testicles themselves, etc., they are enough to cause the sperm's ability to move forward to weaken or even lose.

Although sperm has a re-energization process after entering the female reproductive tract, it is to prepare for sperm to penetrate the egg. We know that before sperm reaches the abdomen of the female fallopian tube cup to meet the egg, it needs to pass through the mucous duct of the cervix and then through the uterine cavity to reach the place of fertilization. In order for sperm to complete this long "journey", it must have power and a "gas station", otherwise, it is impossible to fertilize the egg.

From this point of view, sperm motility is very important for male fertility. It is easy to determine asthenospermia. At present, most hospitals in my country conduct tests according to international standards. The boundaries in the sperm motility test results are clear, and the motility levels are determined by four standards: A, B, C, and D. If the proportion of grade A sperm is less than 25%, it is abnormal. There is also a five-level classification method: grade 0 means that the sperm cannot move; grade 1 means that the sperm has poor motility and only wriggles in place; grade 2 means that the sperm has average motility and only moves forward in a curved line; grade 3 means that the sperm is very active and moves forward in a straight line; grade 4 means that the sperm is extremely active and moves forward in a fast straight line. However, most of the tests currently use the former method.

The proportion of grade A sperm often determines the strength of male fertility. If there are no other problems that affect fertility, as long as less than a quarter of the sperm move in a straight line, it is asthenospermia.

Some people think that as long as the overall motility is high, it is possible to have a baby, but this is not true. For example, if only one tenth of the sperm can move in a straight line, even if there are more B-grade or C-grade sperm, they cannot replace the fertilization function of the sperm that moves in a straight line, and cannot complete the mission of sperm and egg fusion.

It should be noted that relatively less serious asthenospermia can sometimes make a wife pregnant, but this type of pregnancy is prone to embryonic development arrest, miscarriage, and premature birth, which is of course not conducive to eugenics.
