ABSTRACT
<p><b>OBJECTIVE</b>Using nested polymerase chain reaction (PCR) to perform preimplantation gender diagnosis.</p><p><b>METHODS</b>One (or two) lymphocyte and blastomere (n=50/group) were collected and prepared under the following conditions (1) water only (H(2)O); (2) freeze-thaw liquid nitrogen, then boiling; (3) potassium hydroxide/dithiotheriol, heated to 65 degree centigrade, followed by acid neutralization (KOH). Cells were analyzed by PCR using nested primers amplification with amelogenin gene.</p><p><b>RESULTS</b>The amplification rate and allele dropout (ADO) rate for male lymphocytes by the three methods were 83%, 94%, 95% and 24%, 12%, 4%, respectively. Using two cells per reaction did not increase the amplification rate for the KOH method.</p><p><b>CONCLUSION</b>The KOH method for DNA preparation is superior to the other methods evaluated. Dual blastomere biopsy and independent blastomere analysis may improve preimplantation diagnostic reliability.</p>
