Dr. Nayana Patel, studies ultrasound scan on Bharti Utrekar, a surrogate who is seven months pregnant with twins for an American couple, at the Akanksha IVF and surrogacy centre that she founded with her husband, Dr. Hitesh. Dr. Patel completed her first successful surrogacy birth in 2003, and has delivered over 565 babies since the clinic's establishment. When choosing surrogates, they are counselled, and screened following stringent guidelines. Surrogates must be married and have completed their own families with their own children, and the couple must be medically, physically, psychologically, emotionally and mentally sound. While 15% of couples are infertile globally, only 6% of infertility cases require surrogacy as a last option.
