Total sperm motility refers to the motility of all sperm, and a total sperm motility of 40.9% suggests insufficient sperm motility.
One hour after sperm discharge, viable sperm should be above 70%, if below 50% it is abnormal. Normal values are: male A-grade sperm ≥25%, A+B-grade ≥50%, and sperm motility is the sum of A+B+C-grade sperm percentage ≥60%. Therefore, the total sperm motility of 40.9% suggests that the sperm is not sufficiently active, and it is necessary to be alert to whether it will affect fertility.
Clinically, men with decreased sperm motility have varicocele, orchitis, epididymitis and other inflammatory diseases of the reproductive system, as well as the application of certain antimetabolic drugs. However, what causes the decrease in total sperm motility and whether it will cause infertility, all these need to be judged by professional doctors.
To summarize, 40.9% total sperm vitality suggests that the sperms are not active enough, and such a situation still needs to consult a doctor in time and be treated under the doctor’s guidance.
