WebNov 30, 2002 · Counting sperm using a hemacytometer is tedious. An alternative technique is to determine sperm concentration using a spectrophotometer. A spectrophotometer measures the amount of light absorbed by a sample, and the more sperm are in the sample, the more light is absorbed. By generating a standard curve of absorbance versus sperm … WebDiluting a Specimen for Counting on a Hemocytometer Semen must be diluted prior to counting sperm if a hemocytometer is used. In additon to preventing overlapping of sperm cells, the diluting fluid immobilizes the sperm in the chamber to further facilitate counting.
