Dear doctor, we've been trying to conceive for 18 years. Idiopathic sterility primaria. (I'm 48 now; I did not have period for couple of months and at the moment I am on duphaston 3-months therapy). My eggs were useless - poor quality and few. Early menopause. We tried AIH and IVF (poor responder to stimulation), but always with negative beta. Egg donation recommended. QUESTION: Where in the world is it possible (if it is possible at all) to do "three-parents IVF"? Could we use donor's egg, but my DNA? And insert my DNA into an emptied nucleus of another woman's egg? Then that egg could be fertilized with my husband's sperm. Thank you for helping us.

I'm sorry if you misunderstood, but we do not have any doctors in this specialty on this site.

I don't believe what you are proposing is possible. The "emptied nucleus" would render the egg useless. Again, I am not a fertility specialist, and this is only my educated guess as a RN in the maternity field.

Have you discussed with your doctor the dangers of being pregnant at your age?

What you are proposing does seem almost impossible but like the previous post I am not a fertility expert.

I can only think that you must return to your doctor, who will be able to put you in touch with a specialist in this field.they will be able to give you the answers you require.I do hope they are the right ones,you have been trying for so long.
