Patient's question:
Had a testicular ultrasound and a semen quality test. The results showed that I have asthenozoospermia, which can lead to infertility. What are the causes of male infertility?Doctor's answer:
This situation requires looking at the specific reasons. The main causes of male infertility can be summarized into 5 categories:① Sexual dysfunction, including premature ejaculation, retrograde ejaculation, nocturnal emission, and anejaculation. Anejaculation accounts for 32.4% of male infertility causes.
② Abnormal semen quality, including oligozoospermia, azoospermia, asthenozoospermia, teratozoospermia, polyzoospermia, hyposemenia, and semen agglutination. Oligozoospermia accounts for 15.4% of male infertility causes.
③ Varicocele-induced male infertility accounts for 12%.
④ Immunological factors: Refers to the presence of antisperm antibodies in male serum or seminal plasma, leading to autoimmune reactions against sperm and resulting in immunological infertility.
