Hi there! It is appreciatable that after facing so much pain she is still here to have some guidance. Infertility is the worst thing ever happened to women. But don’t lose hope. IVF is the good option if you want biological attachment with your baby. The success rate depends s upon the clinic. But I suggest you go for the safer option. Surrogacy success rate is higher than IVF. IVf can be failed due to some complications. As she’d been through all this already so must go for surrogacy. Now the question is which clinic she should choose. If I suggest you I’ll say go for the clinic in Europe. I had my personal experience from there. They also provide with the surrogate mother. Take care.
