I have a medical condition where I have no vas deferens. Sadly, IVF didn't work. I don't say that to ask for sympathy, but to say that my wife went through the same series of needles, etc, without the payoff at the end. (Additionally I had to have a surgery to remove sperm from the testes, which was painful to recover from as you might imagine.) Anyone who embarks on the financial and emotional cost of IVF needs to be fully aware of the possibility that it won't work.
