Introduction
Sperm motility refers to the ratio of motile sperm to the total sperm count in semen and is a key indicator of sperm quality. According to the World Health Organization’s fifth edition guidelines for semen analysis, the normal reference value for sperm motility is ≥58%, at which point the likelihood of female pregnancy is relatively higher. If more than 50% of the sperm in the semen are non-motile (i.e., immotile or dead), the condition is diagnosed as necrozoospermia.
Many men experience abnormal sperm viability, which can significantly impair male fertility. Thus, sperm viability directly affects whether a man can become a father. So, what level of sperm viability is required for conception?
What Sperm Viability Level Is Required for Conception?
Sperm viability refers to the proportion of live spermatozoa among the total sperm count in a semen sample and is a key indicator of sperm quality. According to the World Health Organization’s fifth edition of semen analysis guidelines, the normal reference value for sperm viability is ≥58%, at which point the likelihood of female conception is relatively high. If more than 50% of sperm in the ejaculate are non-viable, the condition is diagnosed as necrozoospermia. However, low sperm viability does not absolutely preclude pregnancy; successful natural conception depends on multiple factors, including sperm concentration, total sperm count, motility, morphology, and seminal plasma composition.
In daily life, it is important to reduce stress and maintain a relaxed mental state. Regular physical exercise, a balanced diet, and consumption of nutrient-rich foods can help improve overall health and enhance sperm quality.
Additionally, avoid overly frequent sexual intercourse. After intercourse, promptly clean the genital area. Refrain from wearing tight-fitting underwear; instead, opt for loose, breathable cotton undergarments. We hope this information proves helpful to you.
