What are the common symptoms that lead to asthenozoospermia?

Patient's question:

Sperm motility q/A. B0. C! D)/Sperm vitality A/A plus BP/Sperm density 31.9/Color gray-white. pH value 7.3/Boiling time 30 minutes. Leukocytes 6-8 HPF

Doctor's answer:

In cases of asthenozoospermia, sperm lack the strength to move forward, making it difficult for them to penetrate the cervical canal and uterine cavity to reach the fallopian tubes and fertilize the egg, thus leading to impaired fertility. Common causes of asthenozoospermia include:
1. Incomplete maturation or damage to the spermatogenic epithelium in the testes, resulting in poor sperm quality and weak motility;
2. Low seminal fluid volume;
3. Variations in seminal plasma, such as when the epididymis, seminal vesicles, or prostate are inflamed, the pH, oxygen supply, nutrition, and metabolic breakdown may be unfavorable for sperm movement and survival. If anti-sperm antibodies are present, they can cause sperm agglutination, thereby impairing their motility.
