Hello there! Have you guys ever considered going for some kind of a treatment like IUI or IVF? I think the most suitable treatment for you right now would be IVF. You would be able to get a baby easily through that way. The doctors will collect your alive sperms enough to fertilize your wife's egg outside of her body. Then the egg will be transferred back into your wife's womb where it will start to go on with the natural process of pregnancy. This is a very effective treatment with a very high success rate. Many people have got to have their babies through this treatment in front of my own eyes. The prices for this treatment are very high locally. I have seen some successful IVF happening at a clinic named biotexcom. The best part is the low prices. I think this is the only place that can really help you out with your problem. I hope that you take a wise decision regarding your problem and get to have a beautiful baby.
