Using the information provided,calculate the sperm concentration and sperm count:
-Using a 1:20 dilution of a specimen with a volume of 4 mL,30 sperm are counted in two large squares (WBC)of the Neubauer hemocytometer.
A) 1.5 million/mL and 6 million/specimen
B) 3 million/mL and 12 million/specimen
C) 6 million/mL and 24 million/specimen
D) 30 million /mL and 120 million/specimen

Quizplus · Accepted Answer

The sperm concentration is calculated as follows:Sperm concentration = (Number of sperm counted / Number of large squares counted) x Dilution factor x 10^6 / Volume of specimen= (30 / 2) x 20 x 10^6 / 4= 1.5 million/mLThe sperm count is calculated as follows:Sperm count = Sperm concentration x Volume of specimen= 1.5 million/mL x 4 mL= 6 million/specimen
