To quote Geet from Jab We Met, ‘Koi doubt mat rakhna!’
Yes, vasectomies are reversible through surgeries that just reconnects the tubes that carry sperm from the testicles into the semen.
Interestingly, another method under advanced trials for reversible vasectomy is RISUG. Or if you want to sound more professional, Reversible Inhibition of Sperm under Guidance. RISUG is an ‘injectable vasectomy’ which relies on a shot to make you (if you are a male) infertile. And if you ever decide to have babies, another shot and boom, you’re fertile again.
