Study information
Scientific title
Preimplantation genetic screening on day 3 embryos using Comparative Genomic Hybridization (CGH)-array in women of advanced maternal age: a prospective randomised controlled trial
Acronym
PGS by CGH-array on day 3 embryos in AMA patients
Study hypothesis
Patients with advanced maternal age (AMA) (36 - 43 years) have a higher ongoing pregnancy rate after embryo transfer of embryos with a normal chromosomal pattern analysed through 24-chromosome aneuploidy preimplantation genetic screening (PGS) compared with patients who had an embryo transfer without PGS.
Ethics approval
The local ethics committee (Clinica Valle Giulia, Rome, Italy) approved on the 20th October 2010
Study design
Prospective randomised double blinded study

Intervention
1. Control group: ICSI procedure, day 3 zona pellucida laser assisted drilling without blastomere biopsy and Preimplantaion Genetic Screening (PGS), day 5 up to double embryo transfer .
2. Study group: ICSI, one-cell embryo biopsy on day 3 and Preimplantation Genetic Screening with array-CGH, day 5 up to double embryo transfer. Embryos with dubious results will be reanalysed by trofoblast biopsy and array-CGH.
All available supenumerary viable embryos will be cryopreserved by vitrification procedure in both groups.
