Surrogacy is not a big deal these days. It is helping many in need. It has a high success rate. Surrogacy is legal in some countries. It is also cheap there. There are some clinics who offer different packages. One can select the most suitable package.
I know all this because I visited a clinic for IVF. I had a great experience. There is got to know more about surrogacy too. I tried to tell you what I knew the most. I guess you must search for it on your own. You will gather a lot of information in no time. I hope everything goes fine for your friend. Lots of love to her. Baby dust on her. Much love.
