Brief summary

The investigators propose to perform a clinical randomized trial to evaluate the effect of a frozen-thawed embryo transfer and a fresh embryo transfer on pregnancy and implantation rates; with the added benefit of a blastocyst biopsy and whole chromosome analysis by Next Generation Sequencing (NGS).

Detailed description

1. Fresh group: All embryos will be hatched on day 3. Patients will have hatching blastocysts (\*) biopsied on day 5, analyzed by NGS, and will have one or two euploid embryo transferred on day 6, in the am. If more than two euploid blastocysts are available the one(s) to be transferred will be selected based on morphology (\*). Any morulas developing to hatching blastocyst on day-6 will be also analyzed but vitrified for use in a future cycle. 2. Frozen group: All embryos will be hatched on day 3. Patients will have hatching blastocysts (\*) biopsied on day 5 or day 6, embryos will then be vitrified, analyzed by NGS, and will have one or two euploid embryo(s) thawed and transferred on a FET cycle, before noon. If more than two euploid blastocysts are available the one(s) to be transferred will be selected based on morphology (\*). (\*) Hatching blastocysts as described by Gardner and Schoolcraft (1999):

Design outcomes

Primary

MeasureTime frameDescription
Implantation rate8 weeks after replacementdetermining whether a frozen or a fresh embryo transfer will improve implantation rate.

Secondary

MeasureTime frameDescription
Correlation of Mitochondrial DNA and implantationWhen a fetal heartbeat is detected (8 weeks after implantation)The second aim of this study is to determine retrospectively if mt DNA content is linked to implantation potential and if that is measurable by NGS. NGS provides the additional advantage that it can measure mitochondrial DNA, which it's content, seems to be inversely correlated with implantation (Fragouli et al 2013, ASRM).
