At least 531 women have become pregnant despite undergoing permanent birth control operation in Orissa. This was revealed by Health and Family Welfare Minister Prasanna Acharya while replying a question in the Assembly. Though the Government has not taken action against any doctor for fault in conducting the tubectomy surgery, yet it would not hesitate in doing so, the Minister said. As many as 600,369 women underwent family planning operation between 2006-07 to 2010-11 in the State. Out of the 531 women who conceived, 236 were given compensation by different insurance companies under Central government's Family Welfare Insurance Scheme as per a direction of the Supreme Court, Mr. Acharya said.
