Men with normal spermatozoa who meet the clinical evaluation criteria such as semen volume, appearance, consistency and liquefaction ability, PH value, sperm viability, sperm motility, sperm morphology, etc., all of which are normal, are considered normal spermatozoa. The normal value of semen volume is 2-6 ml. Liquefaction ability, normal semen is viscous and jelly-like after discharge, and liquefaction is completed within 30 minutes under the action of semen fibrinolytic enzyme. Sperm viability, normal value is 58%. The sperm count standard for normal fertile men has been controversial for a long time, and the normal minimum value set by WHO is 20×106/ml. Sperm motility, clinically, sperm motility is categorized into four grades, first grade sperm motility is good, second grade sperm motility is better, third grade sperm motility is poor, and fourth grade sperm is inactive, forward motility sperm should generally be at or above 50%, or rapid linear motility sperm should be at or above 25%. Sperm morphology, normal spermatozoa have only one head and one tail, multiple heads and tails are abnormal. Normal morphology spermatozoa ≥ 4%. To summarize, to assess whether a man’s sperm is normal or not requires a variety of tests, if you suspect that your sperm is abnormal, please go to the regular hospital in a timely manner.
