Consequences of polyspermy in man

8 May 2008

Abstract excerpt

Polyspermy occurs with a frequency of about 12% under some hormonal regimens currently being used for in vitro fertilization and embryo transfer. Oocytes with three pronuclei usually show normal cleavage and are morphologically indistinguishable from embryos produced by normal fertilization. Chromosome studies and DNA measurements on dispermic embryos show that about one-half are triploid, the others having...
