Equality in survival of X and Y chromosome-bearing human spermatozoa.
Human X and Y chromosome-bearing spermatozoa survived equally well during washing and resuspension in buffers of pH 5.2 and 8.0 and during incubation in these buffers for 11 hours at 37 degrees C. This suggests that alteration of the ratio of living X- and Y-bearing spermatozoa by direct treatment is not an effective method of sex ratio alteration.
