I think you have posted this same issue earlier also.
Anyways. Any kind of physical assault on spouse is cruelity and hitting on such organs which could cause risk of permanent failure of the organ or even death is covered under grevious hurt.
But yes. Its upto you to decide if you want to lvie with her or not. If you do not want to lvie with her then you should get yourself medically examined and take a medical certificate of the injury (if any). On the basis of this medical certificate you can file a case with local police station.
