What is the chance of getting the desired gender?
Currently, MicroSort sperm separation for female gender selection (XSort) results in an average of 88% X-bearing sperm in the sorted specimen. MicroSort sperm separation for male gender selection (YSort) currently results in an average of 73% Y-bearing sperm in the sorted specimen. These data are determined by fluorescence in situ hybridization (FISH) which allows the number of X- and Y-bearing sperm cells to be counted from a fraction of the sorted sample. A child of the desired gender cannot be guaranteed because the current technology does not completely exclude either female or male sperm cells from the enriched sample. Please view the Current Results page and our Journal Publication page for the most recent data.
