Open to helping others if we can, I can provide sperm either AI or 'NI'

Neither my wife nor I have any identifiable problems but we have been married 8 years and I have tried for a few years without success to make a baby to complete our little family, including IUI, IVF but with no luck and no reason why not could be found.

So we are looking for a lady to help us, but willing to help others at the same time.
