I have seen many such cases in which a friend helped her friend to have a baby. Then why don’t you help your sister? If a friend can help her friend then why can’t a sister can? It looks really great reading your post about this problem. I feel so sorry for your sister. Infertility is really a curse. It’s the worst problem of life for a woman. I can’t tell you about my experience with infertility. I was so depressed and broken just like your sister. I tried again and again but failed. But that’s my story, I can help you. I suggest you a clinic in Europe. That clinic is the best clinic od the world right now. I also had my baby through that clinic. But be careful, that clinic is not Adonis or Lotus.
