We often joke that our bodies have been "hollowed out" recently, and we always talk about tonifying during meals, especially during night snacks when we have two large waists. However, the "asthenozoospermia" mentioned today cannot be solved by "tonifying".
First of all, you need to know what asthenozoospermia is
Generally, within 1-2 hours of male ejaculation, the number of viable sperm is more than 70%, which is normal. If it is less than 50%, it is regarded as abnormal, which belongs to low sperm motility, and we call it asthenospermia.
Secondly, it is important to understand the causes of asthenozoospermia
Reproductive system infection
When there is an infection in the male reproductive system, such as acute and chronic inflammation in organs such as the epididymis, vas deferens, seminal vesicles, and prostate, the vitality of sperm will also significantly decrease.
Inflammatory infection can affect sperm motility in many ways. The direct effect of pathogenic microorganisms on sperm affects sperm motility and the ability to penetrate egg cells; In addition, mycoplasma can cause some sperm membrane defects or even membrane structure damage, affecting the fertilization ability of sperm.
The decrease of sperm motility caused by infection can also be achieved by changing the pH value of seminal plasma. When the pH value is lower than 7 or higher than 8, sperm motility decreases significantly.
Varicocele
Varicocele not only affects spermatogenesis, but also reduces sperm motility. When blood from varicocele is trapped, it can cause local microcirculatory disorders in the testicles, resulting in a lack of nutritional supply and a decrease in oxygen partial pressure. Insufficient energy generation can affect sperm production and activity.
Antisperm antibody
Anti sperm antibodies are a cause of male asthenospermia. If male vas deferens surgery, testicular biopsy, testicular torsion, reproductive tract injury, as well as reproductive tract infection, accessory gland infection, same-sex sexual behavior, etc., may disrupt the blood-testis barrier. If sperm and immune substances in the blood come into contact, the body will produce anti-sperm antibodies.
At this point, the human immune system will launch an attack on sperm, treating them as an antigen. This attack will lead to a decrease in sperm quality, such as increased deformity rate, decreased motility, easy agglutination, coagulation, etc., and a decrease in vitality is the most common.
Bad lifestyle habits
Overeating or partial eating can cause excess or deficiency of some trace elements, thus affecting the sperm motility. When the selenium content in semen decreases, the activity of peroxidase decreases, which cannot inhibit the lipid peroxidation of sperm cell membrane, resulting in sperm damage, increased dead sperm, and decreased vitality.
Smoking, excessive drinking, staying up late, wearing tight pants, or liking to take a sauna, take a hot bath, sweat steam, sleep on an electric blanket, as well as the need for work, prolonged sitting, or working in a hot environment, can easily cause asthenospermia.
The impact of asthenozoospermia on fertility
1. Impact on conception
Only the sperm moving forward can ensure that the sperm reaches the ampulla of the fallopian tube and combines with the egg to form a zygote. In this case, ex vivo sperm will be restricted in their activity before semen liquefaction, and once semen liquefaction occurs, they will immediately exhibit excellent motility.
However, if it is asthenozoospermia, certain factors can affect the motility of sperm, especially sperm that cannot move forward, which will cause sperm to be unable to swim to the position where the egg is located within a certain period of time, making it impossible to achieve the process of conception.
2. Premature or miscarriage prone
Many pregnant women may experience premature birth or miscarriage during pregnancy, which may also be caused by insufficient sperm quality. Therefore, sufficient attention should be paid to asthenospermia
