In recent times India has become a haven for commercial surrogacy, a controversial assisted reproductive technology. Acute poverty means that there are always women ready to rent their wombs. But lack of laws and regulations means there is no transparency in the business of surrogacy and the surrogate mothers are prone to exploitation. The Assisted Reproductive Technology Bill 2013 aims to mend matters. This exploratory study conducted in Kolkata brings to light challenges that any legislation dealing with surrogacy must address. It shows how poor women who rent their wombs for money--ignoring social stigma, health hazards, fear and mental stress--are vulnerable to exploitation.
