Abstract

This study demonstrates that the diploid ratio of tripronuclear zygotes after intracytoplasmic sperm injection (ICSI) is significantly higher as compared with that after conventional IVF; the extra pronucleus of tripronuclear zygotes after ICSI are mostly from the second polar body, not from sperm.
