Patient's question:
I've been married for two years, and my wife hasn't been able to get pregnant. She has undergone various tests, all of which show normal results. The doctor suggested that I also get a sperm test. I'd like to know what the normal levels of sperm A and B grades are.Doctor's answer:
Normal semen volume is about 2—5ml, milky white in color, containing grayish-white clumps, which liquefy spontaneously within 10—20 minutes.pH value: 7.2—8.0
Sperm count: 20—60 million/ml.
Sperm motility: 60%
Sperm vitality is divided into 4 grades:
Grade A indicates excellent sperm motility, with rapid straight forward movement.
Grade B indicates good sperm motility, with straight forward movement.
Recommendation: Normal vitality is A > 25% or A+B > 50%.
