If I have unexplained infertility, is IUI or IVF best?

At First Step IVF, we first do a proper examination and perform IUI, with superovulation method. In normal ovulation only a single egg is formed, but in the superovulation, we try to make 2-3 eggs. This method has given us a huge success rate so far. If this doesn’t work then we move ahead with the IVF.
