Thanks for your query.
I have read your query & I understand your concerns.
Considering your and your wife's age IVF is a good option. But it will be expensive. You request your doctor to perform few cycles of IUI if it is feasible after detailed investigation of you and your wife.
IVF would be definitely ideal treatment in your case.
I hope I answered your query. I will be available for any followup queries you have.
