简要总结
Aim: To investigate the impact of antioxidants (acetyl-L-carnitine, N-acetyl-L-cysteine and a-lipoic acid) on embryo development and subsequently the clinical outcome. Including clinics using low oxygen and ambient air during embryo culture. Analysed with time-lapse system.
Study media: G-TL with antioxidants. Control media: Same media without antioxidants. Type of study: Study comparing blastocyst development on the same cohort of oocytes using two different media, G-TL versus G-TL supplemented with antioxidants. Statistics based on an absolute increase in Good Quality Blastocysts on day 5 of 7%.
Design: Multicentre prospective randomized sibling trial. Single blastocyst transfer. Superiority study Primary Endpoint: Good Quality Blastocysts on day 5 per allocated normally fertilized oocyte.
Patients: Comparative embryo sibling study with 128 patients included.
