The study carried out by the Centre for Family Research at the University of Cambridge says that children born to a surrogate mother have more emotional difficulties than those carried by their biological mother.
The study also suggests that children find it more difficult to handle the idea that they were carried by another woman than that they are not biologically related to their parents.
For the study the researchers followed 30 families who had used a surrogate, 31 that had used egg donation, 35 that had used donor sperm, and 53 that had conceived naturally.
When the surveyed they found that children but that children carried by another woman struggled more than those conceived using donor eggs and sperm. Surrogacy is legal in India but there is no regulation for surrogacy and no agency to check the background of foreigners keen on renting a womb here.
Besides foreigners and Indian couples Bollywood celebrities like Aamir Khan and Shah Rukh Khan have also opted for it.
