Screening of karyotype and semen quality in an artificial insemination program: acceptance and rejection criteria

Semen quality and karyotype were screened in all men offering to be donors for an artificial insemination (AID) program. The criteria for accepting or rejecting semen have now been set with respect to this sample of the population. There was no evidence of differences between the pregnancy rates of the accepted donors. One of 172 potential donors with a clear medical history had a chromosomal abnormality, 4 had pericentric inversions of chromosome 9, and 14 had other heterochromatic variants. Of the recipients of AID, 5 of 196 women had chromosomal abnormalities, and 12 had heterochromatic variants.
