What are the causes of male asthenospermia? "It is very unfortunate for men to suffer from azoospermia, and there may be many reasons for azoospermia. If male friends have a general understanding of these reasons, targeted prevention measures will be taken.". Let's take a look at the cause of asthenospermia!
What are the main causes of asthenospermia? The following points are detailed:
1. Abnormal semen liquefaction:
High viscosity is one of the causes of male infertility, and one of the most important factors may be affecting sperm motility, leading to infertility. Long and thin fibrin can be seen in the non liquefied seminal plasma and interwoven with each other, reducing the space for sperm activity, resulting in sperm being trapped.
2. Infection:
Acute and chronic inflammation of the reproductive tract or glands such as the epididymis, vas deferens, seminal vesicles, and prostate gland can reduce sperm motility. The effects of infection with hypospermia can be manifold. The direct effect of microorganisms on sperm, such as mycoplasma, can be adsorbed on the head, middle section, and tail of sperm, resulting in increased hydrodynamic resistance and slower movement speed when sperm moves forward, affecting sperm motility and the ability to penetrate the egg cell.
3. Immune factors:
Anti sperm antibodies can affect sperm fertilization in several different ways. The impact on sperm motility may be due to the binding of antisperm antibodies to the tail of sperm, which hinders sperm motility, decreases athletic ability, and has poor penetration ability. This has been confirmed by the significant decrease in the ability to penetrate cervical mucus when antisperm antibodies are present in the tail of sperm.
4. Varicocele
Varicocele can lead to male infertility through multiple pathways, which not only affects sperm production, but also leads to decreased sperm motility. The mechanism may be caused by blood retention in varicose veins, microcirculatory disorders, nutritional deficiencies, decreased oxygen partial pressure, insufficient energy production, and endocrine dysfunction.
5. Endocrine factors
Endocrine hormones not only have a role in sperm genesis and maturation, but also affect sperm motility.
6. Chromosome abnormality
In addition to affecting sperm count, autosomal and sex chromosome aberrations also affect sperm viability and forward mobility. It is known that ultrastructural devices related to sperm motility can cause abnormalities in the sperm tail structure due to genetic factors.
