Patient's question:
I am doing well. My husband has oligospermia and asthenozoospermia, and the success rate of artificial insemination.Doctor's answer:
Low sperm count is not necessary for artificial insemination. In cases of asthenozoospermia, sperm lack the strength to move forward, making it difficult for them to penetrate the cervical canal, uterine cavity, and reach the fallopian tubes to fertilize the egg. The common causes of asthenozoospermia include:1. Incomplete maturation or damage to the seminiferous epithelium in the testes, leading to poor sperm quality and weak motility;
2. Low semen volume;
3. Variations in seminal plasma, such as when the epididymis, seminal vesicles, or prostate are inflamed, altering the pH, oxygen supply, nutrients, and metabolic processes, which may either favor or hinder sperm movement. If anti-sperm antibodies are present, they can cause sperm agglutination, thereby reducing their motility.
