Physical methods of evaluation of semen
Objective method of measurement of motility Computer assisted semen analysis system (phase contrast microscope, cameras and control monitor with personal computer with 640 kb CPU co-processor and digitizer with 256 grey valves terminal printer) will yield exact data regarding motility, concentration, velocity of cells, ratio of live cells, quantity of required diluent and straws. It has the capacity of storing entire production information. Impedance change frequency This technique involves the passage of electric current with very low voltage in the freshly collected semen. This impedance caused by motile spermatozoa is recorded in the meter. Semen charged with electric current during impedance change frequency test is safe and can be used subsequently for artificial insemination. Filteration through Sephadex |
