Abstract

Purpose

To determine benefits of cleavage-stage preimplantation genetic screening (PGS) by array comparative genomic hybridization (CGH).

Methods

A retrospective case–control study was performed at a tertiary care university-affiliated medical center. Implantation rate was looked at as a primary outcome. Secondary outcomes included clinical and ongoing pregnancy rates, as well as multiple pregnancy and miscarriage rates. Thirty five patients underwent 39 fresh cycles with PGS by aCGH and 311 similar patients underwent 394 invitro fertilization cycles.

Result(s)

The implantation rate in the CGH group doubled when compared to the control group (52.63 % vs. 19.15 %, p = <0.001), clinical pregnancy rate was higher (69.23 % vs. 43.91 %, p = 0.0002), ongoing pregnancy rate almost doubled (61.54 % vs. 32.49 %, p = <0.0001), multiple pregnancy rate decreased (8.33 % vs. 34.38 %, p = 0.0082) and miscarriage rate trended lower (11.11 % vs. 26.01 %, p = 0.13).

Conclusion

Cleavage stage PGS with CGH is a feasible and safe option for aneuploidy screening that shows excellent outcomes when used in fresh cycles. This is the first report of cleavage stage PGS by CGH showing improved ongoing pregnancy rates.
