I know how difficult TTC and infertility can be. People become so hopeless and lost. Surrogacy, IVF, and IUI are all amazing options for infertility. They have made it easy to fulfill their dreams. My vote would go for surrogacy. Provided she can afford it. IVF might not be as expensive. But it is a very long and painful journey. It usually requires numerous tries. And even those are not guaranteed. With surrogacy, you have better chances of having a child. However, be cautious about scamming clinics. There are so mnay around. For instance, L**** is one of them. You can find forums filled with sad stories of couples being scammed. I hope your friend gets the help needed. I have opted for surrogacy myself.
