In my personal opinion, the advantage is you can discriminate and pick through, the screening process, the embryo that will give you a live birth because the most important fact is that when you go through the IVF procedure the pregnancy rates matter but what matters most is the live birth. When you are a patient what you are looking for after IVF is a healthy baby, a live birth and a healthy baby at home. In my opinion, this is the advantage of the whole process. However if you have a few or bad looking embryos that don’t develop well there is no reason to undertake this type of process. If you don’t have any indications, if you are not older than thirty eight or forty years, have recurrent miscarriages, or repeated IVF failures or if you are really young I don’t think this type of procedure will help you. The disadvantage of this procedure is that it will not increase the chance of having a pregnancy. Even if you don’t do it you will have a pregnancy but the benefit is it will increase your chance of delivering a healthy baby without miscarrying it.
