title: X to Y spermatozoal ratio in normal and oligozoospermic human semen and its relationship to fertility parameters.
abstract: The ratio of X to Y spermatozoa in normo and oligozoospermic human semen is established with a fluorescent technic using quinacrine. The relationship between concentration of X and Y spermatozoa to factors that potentially control the fertilizing ability of spermatozoa (i.e. sperm count, vitality, motility and morphology) is analyzed. Out of a total of 44 samples (22 normo and 22 oligozoospermic samples) a ratio of 1:1 in X to Y spermatozoa is found in both groups. The frequency of X to Y spermatozoa in the evaculate is not related to sperm count. It is also independent from morphology, motility, and vitality of spermatozoa.
