Patient's question:
Hello, I want to ask if it's possible to get pregnant with low sperm vitality. We've been married for more than half a year, and this time we plan to have a baby. The day before yesterday, we went together for pre-pregnancy tests. The results showed that my husband's sperm vitality is low, only 40%, and everything else is fine. We're planning to have a child this month. Can we still get pregnant with low sperm vitality?Doctor's answer:
The normal sperm survival rate in men should be above 70%, with sperm motility grade A being >25% or A+B >50%. In asthenozoospermia, sperm lack the ability to move forward, making it difficult for them to pass through the cervical canal and uterine cavity to reach the fallopian tubes for fertilization with eggs, thus leading to reduced 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 inflammation in the epididymis, seminal vesicles, or prostate, which can negatively affect sperm activity and survival due to changes in pH, oxygen supply, nutrition, and metabolism. If antisperm antibodies are present, they can cause sperm agglutination, rendering them inactive. It is recommended to visit a hospital for further examination to identify the underlying cause and receive targeted treatment to improve sperm quality. Wishing you good health!
