I found this news on Ananova, seems like a few months old, yet still surprising, I don’t know if its really true, but the source looks like a serious one.
I used to live in Serbia when it was part of Yugoslavia, at a very young age that is… well, I was looking out for serbian people and this was a the top of the list in Google… Ouch!!!

Ananova - Serbs line up for testicle shocks.

Men in Serbia are lining up to have electric shocks delivered to their testicles as part of a new contraceptive treatment.

Serbian fertility expert Dr Sava Bojovic, who runs one of the clinics offering the service, said the small electric shock makes men temporarily infertile by stunning their sperm into a state of immobility.

He said: ‘We attach electrodes to either side of the testicles and send low electricity currents flowing through them.

‘This stuns the sperm, effectively putting them to sleep for up to 10 days, which means couples can have sex without fear of getting pregnant.

‘The method does not kill the sperm permanently and it does not affect the patient’s health.’

Dr Bojovic added patients were now lining up at his fertility clinic in Novi Banovci for the shock treatment, as it had none of the problems attached to using condoms, the male pill or having a vasectomy.

He added: ‘We are hoping to have a small battery powered version on sale in the shops in time for Xmas.’”
