• If they targeted Y-bearing sperm, the result was a sperm sample in which 65 percent of the cells contained a Y chromosome, The New York Times reported Wednesday.
• Successful flow cytometric sorting of sperm depends upon the accurate detection of differences in fluorescent signal intensity ( a function of sperm DNA content ) between the X and Y bearing sperm.

• At the conclusion of sorting, a sample of sorted sperm is evaluated for motility, progression, and the degree of enrichment in X-or Y-bearing sperm using fluorescence in situ hybridization ( FISH ).
• Using his " Shettles Method " couples who wanted to have a male baby should time intercourse as close as possible to ovulation to allow the faster y-bearing sperm to reach the egg first.

• Scientists suggest that the Y-bearing sperm are so much better at fertilizing eggs than the X-bearing ones that even though there are fewer of them to begin with, they end up penetrating more than half of all eggs.
• You might be able to imagine many ways this could be achieved, even if males die more; for example, y-bearing sperm might have some kind of advantage in fertilizing ova . contribs ) 07 : 05, 23 December 2009 ( UTC)
• The major factors affecting the fluorescent signals that result from the interaction of the sperm and the laser in the human are sperm head shape, degree of sperm-to-sperm differences in head shape, and the difference in DNA content between X-and Y-bearing sperm ( 2.8 % ).
• The genetic sex is determined by whether a Y bearing or next bearing sperm fertilizes the open; the presence or absence of a Y chromosome in turn determines whether the gonads of the embryo will be testes or ovaries; and the presence or absence of testes, finally, determines whether the sex accessory organs and external genitalia will be male or female.
