The purpose of this study is to develop an algorithm for embryo selection based on amino acid profiling (AAP) of spent culture medium. Development of the algorithm will be based on the ongoing implantation rate of the individual embryos transferred. As evaluated by ultrasound scan in gestational week 7.
IVF/ICSI treatment has permitted many thousands of couples to conceive worldwide yet is limited by low success rates (in UK, approx. 25% live birth rate/treatment cycle for women up to 42 years of age; HFEA Annual Report, 2006) and a confounding high multiple birth rate (23%) due to the transfer of more than a single pre-implantation embryo. Multiple births are associated with prematurity, increased neonatal and maternal mortality and child handicap as well as being a major burden for health care systems. These problems have been highlighted in the data published by the HFEA (2009), which has called for "a professionally-led, coordinated national strategy to reduce the number of multiple births". This challenge could be met if single embryos of known developmental competence could be selected for transfer, thereby making the embryo selection process even more crucial. However, current non-invasive embryo selection criteria using light microscope analysis have limited predictive value for ongoing pregnancy.

10
The Hewitt Centre for Reproductive Medicine, Liverpool Women's Hospital
Liverpool, United Kingdom
Hammersmith IVF, Hammersmith Hospital

Amino acid profile
Amino acid profiling (AAP) will be performed of spent culture medium from individually cultured embryos. AAP results will be correlated to the ongoing implantation rate week 7 as well as morphological embryo development parametres.
Time frame: After 24 hours of culture
Ongoing clinical pregnancy rate
Evaluated by ultrasound scan
Time frame: Gestational week 7
