The drive to sterilise began in the 1970s when, encouraged by loans amounting to tens of millions of dollars from the World Bank, the Swedish International Development Authority and the UN Population Fund, India embarked on an ambitious population control programme.

During the 1975 Emergency - when civil liberties were suspended - Sanjay Gandhi, son of the former Prime Minister Indira Gandhi, began what was described by many as a "gruesome campaign" to sterilise poor men. There were reports of police cordoning off villages and virtually dragging the men to surgery.

An astonishing 6.2 million Indian men were sterilised in just a year, which was "15 times the number of people sterilised by the Nazis", according to science journalist Mara Hvistendahl. Two thousand men died from botched operations.

Since family planning efforts began in the 1970s, India has focused its population control efforts on women, even though, as scientists say, sterilisations are easier to perform in men. "This may be because women are deemed less likely to protest," says Ms Hvistendahl.

India carried out nearly 4 million sterilisations during 2013-2014, according to official figures. Less than 100,000 of these surgeries were done on men. More than 700 deaths were reported due to botched surgeries between 2009 and 2012. There were 356 reported cases of complications arising out of the surgeries.
