Because this modern world just isn't fucking weird enough:

Officials in central Madhya Pradesh state's Shivpuri district decided to adopt the policy—already tried out by some neighbouring states—to increase the low vascectomy rate.

"I came to know that it had to do with their perceived notion of manliness," said Manish Shrivastav, administrative chief of Shivpuri district, part of the Indian Chambal region, which is famed for its lawlessness and bandits.

"I then decided to match it with a bigger symbol of manliness—a gun licence," he said. "And the ploy worked."...

"I never bothered to apply for a licence before because I knew it was not so easy to get," said Shivpuri resident K.K. Saxena, 55, who recently underwent the procedure. "But when I heard about this then I decided to apply."

Saxena was provided with a medical slip confirming his sterilisation to attach to his gun application.

About 10,000 to 15,000 people apply each year for gun licences in Shivpuri, but only about 500 permits are granted annually.

Here's hoping the Supreme Court, currently hearing its major gun-control case since 1939, doesn't read about this.
