Do you always wish you looked like the filmy studs of Bollywood Salman or Akshay? The simple yoghurt or dahi might help. Scientists from the Massachusetts Institute of Technology (MIT) found that eating probiotic yoghurt could boost your virility. They found male mice fed the vanilla-flavoured dessert had a certain 'swagger' when they walked. These mice had testicles that were five percent higher than other mice on a normal diet and 15 percent heavier than junk-eating males. Besides in mating experiments yoghurt-eating males inseminated their partners more quickly and produced more young than control mice not on a yoghurt diet.
