Abstract

We are reporting on a possible association between multinucleated spermatozoa and polyploidy after in vitro fertilization. The semen from the male partner of a couple with 40% polyploidy on three in vitro fertilization attempts was examined by light and transmission electron microscopy. In that sample 10% to 12% of spermatozoa demonstrated conjoined or double heads. The significance of these findings is discussed.
