We propose to perform a clinical randomized trial to evaluate the effect of blastocyst
biopsy and whole chromosome analysis by Next Generation Sequencing (NGS) in comparison to
standard Assisted Reproductive Technologies (ART) methods on on implantation rates,
miscarriage rates, and pregnancy rates.
This will be three studies into one: a) a comparison of treatment (NGS) and no treatment, b)
a non-selection study based on the control group for which we will replace without knowing
the ploidy of the embryos, but we will know it later, c) a retrospective study about the use
of Mitochondrial DNA as a selection tool.

Eligibility |
Inclusion Criteria: - All patients medically cleared to do a fresh or frozen embryo transfer. - Age up to 42 years Exclusion Criteria: - microsurgical epididymal sperm aspiration (MESA) and Testicular sperm extraction (TESE) patients - At least one partner carrier of a chromosomal or genetic disease - Abnormal ovarian reserve, defined as follicle stimulating hormone (FSH) of >10 IU/L on day 2-4 of the cycle and anti-mullerian hormone (AMH) < 1ng /ml (If only one of the two parameters altered then patients is acceptable). This is based on Mandy Katz abstract at American Society for Reproductive Medicine (ASRM) 2011 where they showed that these patients have 35% chance of having no euploid embryos - They are excluded only to make the study size smaller, otherwise, if an euploid embryo is found in these patients, they implant as well as patients with normal ovarian reserve. Not all centers do AMH testing - we recommend first to run FSH and only test AMH if FSH is abnormal. - Egg donor cycle (sperm donor is acceptable) - Gender selection cycles - Thaw cycles |

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Other | Correlation of Mitochondrial DNA and implantation | The third 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). | When a fetal heartbeat is detected (8 weeks after implantation) | No |
Primary | improvement in ongoing implantation rates | We foresee a significant increase in ongoing implantation rates in the Test group compared to the Control group based on several studies showing about a 50% improvement of implantation rates after Preimplantation Genetic Diagnosis (PGD) with blastocyst biopsy and comprehensive chromosome analysis techniques The center participating in the study has an average 41.5% implantation rate of blastocysts in patients 35-39 years of age without PGD. Assuming that NGS will increase the detection power of chromosome abnormalities, we expect a higher implantation rate in the test group. Furthermore, we expect a 6% miscarriage rate in the Test group, based on extensive data from array comparative genomic hybridization (aCGH) results (Hodes-Wertz et al. 2012), while about 21% in the Control group based on Society for Assisted Reproductive Technologies (SART) data (ages 35-40, SART 2011). |
When a fetal heartbeat is detected for each patient. (8 weeks after implantation). | No |
Secondary | Determine specificity and sensitivity rates | The pregnancy outcome of Controls patients with euploid embryos replaced will be compared to that of control patients with aneuploid embryos replaced. This will give us the specificity of the test (false positive rate) by obtaining the ongoing pregnancy rate of cycles with aneuploid embryos replaced, and the sensitivity of the test (false negative rate) by obtaining the miscarriage rate and ongoing pregnancy rate of cycles with euploid embryos replaced. | During a pregnancy term | No |
