Brief summary

The purpose of this research study is to evaluate a newly developed embryo culture media system for human clinical use in ART.

Detailed description

Egg retrieval will be performed as per standard operating procedures. Eggs from a single patient are mixed together in a single group during the normal recovery and washing procedure following egg retrieval. The single group of eggs will be divided in half, then the embryologist will randomly place each half into one of the two culture media treatments, commercial or experimental. All mature eggs collected at retrieval will undergo fertilization per standard operating procedures according to physician recommendations. After fertilization (day 0), standard procedures involve in vitro embryo culture in a sequential two step media system. After confirmation of fertilization success on day 1, embryos are cultured until day 3 in step 1 medium (both commercial and experimental media are two step sequential culture systems). On day 3, embryos are evaluated and moved from step one to step two culture medium. On day 5 and day 6, embryo development will be assessed. Good quality blastocysts will either be transferred fresh or cryopreserved for later transfer and/or genetic testing.
