What is the cause of oligoasthenozoospermia?

In our daily life, we often hear about people who are infertile. The reason may be on the woman or the man. For the latter, it may be because of the activity or quantity of sperm. Let's take a look at the specific reasons for this situation on the man.

Oligospermia refers to a condition in which the number of sperm in semen is lower than normal. If the number of sperm in a man is less than 20 million per milliliter, it is called oligospermia, which will have a great impact on fertility. According to the test results of sperm, if it is less than 20 million and greater than 10 million, it is called mild oligospermia; if it is less than 10 million and greater than 5 million, it is called moderate; if it is less than 5 million, it is called severe oligospermia. If only a few sperm can be found under high-power vision, or only a few sperm can be seen after centrifugation, it is very few, which is called severe oligospermia.

Reduced sperm motility is also called asthenospermia, which can be divided into three degrees according to clinical manifestations: Mild: generally refers to grade A + grade B sperm less than 50%, but greater than 30% or grade A sperm less than 25%, but greater than 10%; Moderate: grade A + grade B sperm less than 50%, but greater than 30%, of which grade A sperm is less than 10%; Severe low sperm motility is manifested as the number of grade B + grade C sperm less than 30%, of which grade A sperm is zero.

According to clinical data, oligospermia, asthenospermia and sperm problems are usually related to urogenital inflammation, varicocele, testicular abnormalities, anti-sperm antibodies and other factors. In addition, unbalanced eating habits can also cause oligospermia and asthenospermia.

(I) Inflammation of the urogenital system: Acute and chronic inflammation of the reproductive tract or reproductive glands such as the epididymis, vas deferens, seminal vesicles and prostate can affect sperm, resulting in a decrease in sperm count and reduced sperm motility.

(ii) Varicose vein: Due to the obstruction of blood circulation in the testicles and epididymis, the local temperature rises and toxic substances accumulate, which causes sperm production obstruction and changes in the optimal living environment of sperm, resulting in oligospermia and weak sperm.

(III) Testicular abnormality: Testicles are the "factory" that produces sperm and are closely related to the survival of sperm. If testicular abnormalities occur, the sperm microenvironment will undergo a "dramatic change", which will lead to a series of problems, such as low sperm count, weak sperm count, etc.

(IV) Immune factors: Antisperm antibodies may affect sperm motility by binding to the sperm tail, which hinders sperm motility, reduces motility, and reduces penetration. At the same time, it is also closely related to the number of sperm.

After reading the whole article, I believe that male friends know what causes their weakness in this aspect, and they should also know how to solve it. In short, we should develop good habits in daily life to avoid these embarrassing problems. Finally, I wish the patient a speedy recovery.
