Frozen embryos 'could result in fewer pregnancies'

This is an encouraging study that provides some evidence that the pregnancy and early outcome for babies may be better after embryos have been frozen.

It is of some concern that conclusions have been drawn, incorrectly... that we should routinely freeze all embryos and transfer them in a future menstrual cycle.

There is ample evidence to show that this would result in fewer pregnancies even if the outcome for those pregnancies were better.
