Freeze-all cycles

There has been growing interest in the idea of “freeze-all” cycles, where rather than having a fresh embryo transfer after eggs have been fertilised in IVF, all embryos are frozen to be transferred at a later date. The logic behind the theory is that the woman’s body has time to readjust after the hormones used to stimulate the ovaries, and that this may help the womb lining and improve the chances of implantation and a successful pregnancy.

It isn’t clear yet whether this theory holds water, but there is a national research study underway to look at this. Those taking part can be in their first, second or third treatment cycle and although the study doesn’t cover the cost of the treatment itself, it does allow for freezing with no additional cost. A number of centres across the UK are taking part in the study, known as E-Freeze, and if you would like to find out more, you can find the website hereĀ
