If you have no other problems going on, ie, JUST an egg problem then newlife in Thessaloniki would be a great place to start going on the reviews on here, only problem is if you have immune type issues, the dr doesn’t believe in them, so you would need a fs where you live to prescribe the drugs you would need for the cycle. Iakentro is good. Also embryoland is a popular clinic, not so much on this forums but others, and it seems as popular as newlife. Three clinics to stay away from are ovum, and genesis, although being greek you may fare ok there, it’s extremely busy and your left waiting for hours for appointments and even transfer, I had a friend who was totally ripped off at that clinic and have read of some not very nice experiences there also, the other is embio, another one that is supposedly a top clinic but I’ve had first hand experience and I wouldn’t go near it again even if the cycle was free or someone paid me.
There are a couple of other good clinics there as well, but you do have to do your research.
