Apoptotic gene expression in potentially fertile and subfertile men.

abstract：:The use of interphase fluorescent in situ hybridization (FISH) has shown that a large number of human embryos exhibit chromosomal abnormalities in vitro. The most common abnormality is mosaicism which is seen in up to 50% of preimplantation embryos at all stages of development. In this study, comparative genomic hybri...
