You can’t hit or kick the groin. Really?
Nearly all martial arts disciplines have strict rules about striking certain parts of the body. The neck and eyes, for example, are always off-limits, and certainly holds are outlawed also. But due to the location on the body, both men and women are at great risk of hits to the genitals. This is not only terribly painful, but it can cause serious injury also. While the vast majority of amateur and professionally trained MMA artists respect this and work to avoid it, accidents do happen. But accidents are not the only issue.
