I can recomend Dr. Michael Singer located near Zurich Enge.
www.singer.ch
I went for an initial consultation in September, one month after arriving to Switzerland, no referal, no waiting lists. I started IVF treatment in October and in November I got pregnant and surpisingly with twins.
He is very kind, delicate and most importantly, know what he is doing. He speaks a bunch of languages very well. I love him.
I previously had 6 IUI's and one failed IVF in Holland.
This cost us about CHF6500 but as they say... getting a positive pregancy test... priceless....
Good luck!
