Interpretation of common causes of asthenospermia: real killer with low sperm success rate

Asthenospermia represents a very low probability for men to make women pregnant. For ordinary men, asthenospermia, impotence and premature ejaculation have a great psychological impact. Generally, 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 fertilized egg. The normal sperm in vitro, before the liquefaction of semen, is restricted in activity. After the liquefaction of semen, it immediately shows good movement ability. If some factors affect the movement function of sperm, especially those who cannot move forward, the sperm cannot swim to the position of the egg in the best time, nor can it be fertilized.

What are the causes of asthenospermia?

1. Varicocele

Varicose blood retention, microcirculatory disturbance, lack of nutrition and lower oxygen partial pressure, lack of energy generation and endocrine dysfunction.

2. Abnormal semen liquefaction leads to hypospermia

Non-liquefaction or high viscosity of semen is one of the causes of asthenospermia, which causes male infertility. One of the important factors may be the influence of sperm motility leading to infertility. Thin and long fibrin can be seen in the non-liquefied seminal plasma, which can reduce the space of sperm activity by interwoven. While sperm is restrained, many fine fibers can also be seen in the coarse fibers connected to the Internet, which may be the reason for mechanically restricting sperm forward movement.

3. Infection

Acute and chronic inflammation of the reproductive tract or reproductive glands such as epididymis, vas deferens, seminal vesicles and prostate can reduce sperm motility.

4. Immune factors

Antisperm antibodies (AsAb) can affect sperm fertilization function in several different ways. The effect on sperm motility may be the combination of AsA b and sperm tail, which hinders sperm motility, reduces movement ability, and has poor penetration ability. This has been confirmed by the significant decrease in the ability to penetrate cervical mucus when anti-sperm antibody is present at sperm tail.

5. Endocrine factors

Endocrine hormones not only play a role in spermatogenesis and maturation, but also affect sperm motility.

6. Chromosome abnormality

In addition to affecting sperm number, autosomal and sex chromosome aberrations also affect sperm viability and forward mobility.

Whose fault is the low sperm success rate

Before we know the normal problem of sperm survival rate, let's look at the eight reasons for the low sperm success rate.
