From research, 仁安 should be the best, my sister's bb also come from there through iVF, now her bb is already 3 yrs old, healthy, smart, naughty....
Heard that Dr Tung is the best, but i marked Dr Chow, most of their doctors are ok.
IVF的成功率 depends on your age and health....successful rate better than IUI...however, as my age, even me and my husband no problem, just with abt 15 -20% successful rate.
