Quality beats quantity anytime of the day. Why am I saying this? Because you might have been retrieved only one egg but it comes out successful. Rather than having 10 eggs retrieved and from all of them none will be helpful. You should consult your embryologist to give you more information. Cause concerning the quality and quantity it might be more related to sperms than eggs. Where the sperm quantity counts. Also this can be beaten by the fact of more quality sperms than quantity. I am not really conversant with this topic. So it is better if you ask a professional about it. But I do believe that there is a good clinic out there that can help you. With such information and experience that you have gone through. If you have more information that you think might be helpful kindly reach us back.
