What is the normal sperm viability rate for healthy males?
Disease description:
Nowadays, many couples face infertility or subfertility issues—some due to low sperm viability, while others even have necrospermia (a condition where all sperm are nonviable). Could you please clarify: what is the normal sperm viability rate for healthy adult males?

Dr. Luo Yong
A normal sperm viability rate in males is greater than 80%, with a progressive motility (climbing height) exceeding 5 cm, abnormal sperm morphology less than 10%, and the ability to move directionally. To maintain optimal sperm viability, men may consult a physician for a comprehensive health evaluation to identify any nutritional deficiencies and receive targeted supplementation. It is essential for men to quit smoking and alcohol consumption and avoid exposure to electronic radiation. Additionally, consuming foods rich in vitamins—such as goji berries, tomatoes, and kelp—can help enhance sperm motility and overall vitality.
