I also feel that Dr. Tay is very nice and patient. However, I have tried 3 IVF cycles with him without success. I will consult about 4 IVF doctors (Dr. Milton Leong, Dr. Alex Doo, Dr. Philip Ho, and Prof. Haines) before deciding what to do next as IVF is very expensive... Any suggestion of IVF doctors good at dealing with repetitive failure cases?
