Abstract
A method for measuring the total sperm concentration (TSC) in a sample is described and includes: (i) placing the sample in a transparent container between a synchronically pulsed light source and a photodetector; and (ii) measuring the optical absorbance of the sample in the range of 800-1000 nm, the TSC of the sample being proportional to the absorbance. Also described is a sampling device for use in optically analyzing a biological fluid, a method for measuring motile sperm concentration (MSC) in a semen sample, a method of determining the average velocity (AV) of sperm cells and a system for analyzing semen quality including means for measuring TSC, means for measuring MSC; and a video visualization system.

A sampling device for use in optically analyzing a biological fluid comprising:
- (i) an aspirator for aspirating the fluid into the device;
- (ii) a thin measuring chamber having an upper and lower wall, the distance between said walls being in the range of 100-500 microns;
- (iii) a thick measuring chamber having an upper and lower wall, the distance between said walls being in the range of 0.5-3 cm;
- and
- (iv) means for excluding air from said measuring chambers;
- wherein the upper and lower walls of said thin and thick measuring chambers are transparent and the thin measuring chamber and the thick measuring chambers are in fluid communication.
