A Switch That Turns Your Sperm Off?

Guys who love to bareback everywhere just let out a collective shout of joy. No longer will they be forced to pull out like tamed animals. No longer will they have to worry that every text message after a one-night-stand is going to say ‘I’m late’. A new invention by German inventor Clemens Bimek aims to install a ‘sperm switch’ will let men turn their fertility on and off.

The switch will be implanted into the scrotum, and is both hormone-free and not permanent. The procedure should only take 30 minutes, and there is no down time after.

The idea could revolutionize sex, at least for straight people. It is meant to replace both condoms and pills, although obviously the only STD it actually protects from is unwanted babies.
