The existing data do have a number of limitations which need to be addressed in the context of further research before this strategy should be rolled out into routine clinical practice.
The initial step must be to provide robust evidence to demonstrate that elective freezing of embryos can increase the chances of having a healthy baby, which would be best performed in the context of a large randomised controlled trial.
In the meantime my advice to women undergoing IVF is that there is no reason, yet, to change the way they approach IVF.
Frozen embryos are more likely to produce successful, complication-free IVF pregnancies than those that are fresh, research suggests.
