One of the most prevalent myths I’ve noticed over the years in the martial arts community is efficacy of hitting men in the groin as a one-stop solution to the problem of physical violence.
There is no doubt that strikes to that area can be effective. But a number of people teaching them as part of a self defence curriculum seem rely on them far too much. Like any target on the body, depending on numerous factors, they can range from being fight stoppers to unnoticed insignificant body shots.
In terms of targets, with regard to men, these are the groin itself and the testicles.
- Frontal groin impact can cause severe pain if the muscles there are relaxed or weak and the bladder is full (and might perhaps cause rupturing of the bladder), but this is by no means certain. Of more use perhaps is the unbalancing effect that groin shots can have on the angle of the subject’s pelvis, creating opportunities for escape or further strikes. While I cannot speak from personal experience (and it isn’t a question I ask or get asked regularly), the same impact on women may well traumatise the female reproductive system and cause pain.
- While most men have probably experienced pain in the testicles at some point in time due to impact, compression or movement, none of these can be guaranteed by a direct hit at any angle.
To a large degree the effectiveness of groin strikes relies on pain compliance. Factors involved here are the angle and force of impact in terms of whether it affects the target to elicit a normal pain response, and whether the chemistry of the body at the time is such that it recognises and responds in a useful fashion to that stimulus.
There is no doubt that are lots of possible ways to attack the groin. The Enter the Dojo show regularly parodies the over reliance of some on this target and Master Ken has demonstrated 100 ways to attack the groin.
Hitting the groin effectively outside of prearranged combinations is not always easy. If people are actively resisting each other and are hands-on, often the angle of the body is such that the groin is further back than the rest of the torso making it less accessible. Overly tight or loose cut clothing can often impede upward strikes towards the testicles. A further factor is that you get good at what you train for: obviously it may seem to be a ‘natural’ target, but you’ll tend to be better at hitting the things you practice targeting. That’s not to say that groin/testicle shots can’t happen. I have seen numerous accidental ‘hard’ groin shots in training to people without cups and effects have ranged from them being unnoticed, unbalancing knock backs (creating an opportunity for follow ups) or fight stoppers.


A large factor in this has often been how intense the training was – the less intense, the more mentally and physically relaxed the recipient, the more effective the strike. Those who were fully committed to attacking the striker often did not notice they had been hit. It is the unexpected nature of the impact as much as the impact itself that can frame the response. On a number of occasions I have been unaware of being caught until an hour or so after training when I have literally doubled over while sitting at a table as if I had just been hit; the body had been sending pain signals but adrenaline related chemical factors had inhibited their recognition.


Do groin strikes have their place in a self defence curriculum?
Of course they do.
As with every other strike we should be prepared for failure and have a redundancy trained in place for when they do not work. We do not expect every hit to the head to result in a knockout (although such strikes can be devastating and should always be context appropriate), nor do we expect every knock to the leg to cause a person to fall to the ground desisting in attack or pursuit. Groin strikes can be part of a repertoire, they can be effective, but they are not a guaranteed escape plan and to paint them as such is simply bollocks.
