Egg Shape

I have just had my eggs collected and 4 have fertilised out of 7. However, I've been told that 2 of the fertilised eggs are slightly oval in shape - what is the significance of this and does this mean that they have less chance of developing?

The usual shape of a human egg is round however it is quite common for eggs to have an oval shape. Researchers opinions differ as to the significance of unusual oocyte morphology. Some found it does affect the chance of success whereas other groups have reported no difference. We have had live births from oval eggs at Manchester Fertility.
