I'm not sure how it works, but if my hubby already had a child and we were entitled you should be too although I'm not sure if its based on the mother, you would think if the problem is with the man and its a different partner then its only fair!, but we had unexplained infertility, so had to try for 3 years before the IVF referral, we had to play ball and try everything they suggested, even taking drugs to make me ovulate even though I was every month anyway,I had a lap and dye op to see if tubes were ok, they were fine, I found the whole experience at St Albans a nightmare and I'm not the only one they have a reputation for mucking people about, you just have to know your stuff or lie and say you were trying longer etc. also they will look at your diet so go in prepared to be quizzed about everything. The first meeting with the nurse was ok she booked us in for more tests and the lap and dye so that happened quite quickly, then it just dragged on for ages seeing someone different each time we went having to explain the whole thing to someone else!
If you do get referred and you might as they know there is a problem so no need to wait, let me know and I can tell you all about the drug treatment what to expect and that the process is the same for ICSI/IVF, it was tough but also amazing what they can do to help! xxx

This is where we went the statistics are quite good and I compared all the clinics on the list and decided this was the best and I also like the fact that they are private, but just started taking on NHS a year or so ago, you are treated exactly the same!
