Role of Male Factor Testing in Recurrent Pregnancy Loss or In Vitro Fertilization Failure.

Abstract

The appropriate management for male partners of couples with recurrent pregnancy loss (RPL) or recurrent implantation failure during in vitro fertilization (IVF) remains unclear. In particular, men with normal semen parameters are often ignored because the “bulk semen parameters” appear normal [1]. Despite normal semen parameters, male partners in couples with RPL or recurrent implantation failure could have underlying genetic abnormalities in sperm DNA that can be identified. There are a couple of diagnostic tests that we recommend in the evaluation of these men, the first being DNA Fragmentation Index (DFI) and the second, fluorescence in situ hybridization (FISH) for evaluating sperm aneuploidy.
