Does low sperm survival rate affect pregnancy?

A man's low sperm survival rate is what we often call asthenospermia. There are many reasons for asthenospermia, and most of them are caused by bad daily habits, but it may also be caused by the man's poor physical condition and some diseases. Therefore, infertility is not entirely due to the female side, and to some extent, the male side is also partly responsible. For example, the sperm survival rate is closely related to whether or not pregnancy can be achieved.

So what circumstances can easily lead to low sperm survival rate in men?

1. High temperature environment. If men are in a high temperature environment for a long time, it will be very harmful to sperm and affect sperm survival.

2. Sperm failure to liquefy. If sperm failure to liquefy occurs, it will affect the sperm's penetration ability, resulting in the sperm being unable to penetrate the cervix.

3. Depression. Long-term depression and poor mental state in men will affect the testicular spermatogenesis ability and sperm count, resulting in a decrease in sperm survival rate.

4. Lack of nutrition. Sperm needs nutrition to survive. If sperm lacks nutrition, it will cause sperm death, resulting in a decrease in sperm survival rate.

In addition, some diseases can also affect the survival rate of sperm. The causes of asthenozoospermia include acute and chronic inflammation of the reproductive tract or reproductive glands such as the epididymis, vas deferens, seminal vesicles and prostate, varicocele, immune and endocrine factors, chromosomal abnormalities, etc.

Low sperm survival rate will also bring a series of hazards, such as:

① The testicular spermatogenic epithelium is not fully mature or is damaged and thinned, resulting in poor sperm quality, weak motility, and small semen volume.

② Sperm mutations. For example, when there is inflammation in the epididymis, seminal vesicle, prostate, etc., the acidity, alkalinity, oxygen supply, nutrition, metabolism, etc. are not conducive to the activity and survival of sperm.

③If antisperm antibodies are present, sperm can also be agglutinated, thus losing their ability to move.

In short, low sperm survival rate directly determines a man's fertility. A low survival rate is very dangerous, which greatly reduces the fertility of couples. Although there is a possibility of fertility, the quality of the fetus will also be threatened, which requires the majority of male compatriots to pay enough attention.
