Rotational and translational swimming of human spermatozoa: a dynamic laser light scattering study

|July 1, 1984
Abstract:
The rotational swimming motion of human spermatozoa is evaluated from measurements of depolarized dynamic laser light scattering at zero angle. The analysis is based on a Maxwellian angular velocity distribution and yields a rotational frequency of about 4 Hz that is ascribed to the rotation of the sperm head. From comparison with the translational swimming motion, a propelling efficiency of about 10 micron per turn is deduced. This parameter describes the linkage between the rotational and translational swimming motion and is likely to be discriminatory in the analysis of physiological and pathological sperm motions.
