Abstrakt: We report the world's first clinical pregnancy resulting from DNA-based enrichment for X-bearing human spermatozoa, for prevention of X-linked hydrocephalus. Sperm separation was followed by embryo biopsy and nested multiplex polymerase chain reaction (PCR) for gender determination. Enriched populations of X-bearing spermatozoa ranging from 80 to 89% pure as determined by fluorescence in-situ hybridization (FISH) resulted in in-vitro fertilization (IVF) rates indistinguishable from normal IVF procedures (65%). In two separate biopsy procedures, 7/9 and 15/16 of the resulting embryos were determined to be female by multiplex PCR. Embryo transfer resulted in a karyotypically normal female fetus. This technique should be widely applicable to gender selection for the prevention of genetic disorders. [ABSTRACT FROM AUTHOR]
