A brief description of the causes of asthenozoospermia, I shed tears when I knew the truth
Asthenozoospermia refers to a condition in which less than 50% of sperm (a+b grade) with forward movement or less than 25% of sperm with rapid forward movement (a grade) in semen, commonly known as low sperm motility in clinical practice. And it is one of the most common clinical manifestations of male infertility, closely related to many diseases that cause male infertility.
What causes:
1. Reproductive system infections, such as chronic prostatitis, seminal vesiculitis, mycoplasma, chlamydia infections, etc., can affect sperm motility.
2. Varicocele: Blood stasis, increased local temperature in the testicles, and inability to expel certain toxins (such as catechins).
3. Biochemical abnormalities in seminal plasma: low sugar or a-glycosidase levels.
4. Endocrine factors: When the level of estrogen in the serum increases, it reduces the activity of sperm; Excessive testosterone in seminal plasma can inhibit sperm motility.
5. Ciliary immobility syndrome, also known as Kartagner syndrome. This is a congenital ciliary structure defect. It is also possible to learn from the medical history that there is a history of chronic respiratory infections.
6. Immune factors: Anti sperm antibodies (AsAb) mainly bind AsAb to the head and entire tail of sperm, which inhibits the forward movement of sperm.
7. Long term abstinence: Sperm survival time is only 28 days.
8. Other factors include deficiency of trace elements (such as zinc) and vitamin deficiency (such as vitamin A, vitamin C, and vitamin E).
