India is the world's top sterilizer of women.
From 2013 to 2014, over 4 million Indian women had the surgery, making it the most popular form of birth control.
At 1.3 billion people, India is projected to overtake China's population around 2028. India's solution is free sterilizations for men and women.
The procedures aren't always safe. Patients describe filthy conditions and hasty surgeries.
Sometimes women are paid to get sterilized or offered incentives like "cars, gold coins and drawings for prizes."
In November 2014, 15 women died at two state-run "sterilization camps." Between 2003 and 2012, a total of 1,434 people died.
Most were women. Only 1 percent of men undergo vasectomies because male sterilization isn't socially acceptable.
Prime Minister Narendra Modi has pledged to improve India's health system.
This year family planning centers will begin offering free injectible contraceptives.
