I've heard great things about infertility treatments in Cyprus (which is an island off the coast of Turkey) and even India. I'm thinking about Cyprus as my top choice...you should look into it as well.
I found this information online at Where is My Docotr. It's been a great resource for me while I've been researching IVF treatments abroad. I would highly recommend checking out this site. Also Visit and Care is an online service that will set you up with the best clinics, and I've personally talked to their staff. They are experts and so helpful.
I am still weighing my options, but if you are looking for other possible alternatives, I would definitely say to check both of those places out.
I wish you all the best with everything!
