TILT: Time-Lapse Imaging Trial - A pragmatic, multi-centre, three-arm randomised controlled trial to assess the clinical effectiveness and safety of time lapse imaging in in-vitro fertilisation treatment.
Many couples experience problems becoming pregnant. They often undergo procedures such as in-vitro fertilisation/intracytoplasmic sperm injection (IVF/ICSI) where an embryo is implanted into the womb to help them become pregnant, however this does not always work. Although the number of women having IVF/ICSI is increasing, the success rates are less than ideal and have remained similar over the last few years.
The success rate of IVF/ICSI depends on the ability to select the best embryo for transfer, and transferring more than one embryo to increase the likelihood of success can result in multiple births. Part of the problem is there is a lack of evidence regarding the best method to choose which embryo to use. National guidelines and fertility experts recommend further research into methods to improve embryo selection. Time lapse imaging (TLI) is a newer technology available in IVF/ICSI laboratories. It is hypothesised to improve the accuracy for embryo selection from a group of available embryos. In addition, it also provides an undisturbed environment for the embryos when they are developing.
-The primary objective of the trial is to determine if the use of TLI or undisturbed culture in IVF/ICSI treatment results in a higher live birth rate when compared to current standard methods of embryo incubation and assessment.
