It is an age old debate and in the battle of the sexes we are fiercely divided over one particular question: who has it worse when it comes to pain?
While supermodel mother Gisele bragged that childbirth 'didn't hurt in the slightest', most women will agree that it is single-handedly one of the most painful experiences of their lives.
The same can be said for men when it comes to the crippling pain of being kicked in the groin.
But which hurts more? One scientific video thinks it has the answer.
Pain competition: The age old debate of whether childbirth or being kicked in the groin is more painful is fiercely contested, and now one video thinks it has an answer
The fun illustrated video delves deep into the question and begins: 'On the one hand, women are left fitting a watermelon sized object through a coin-sized hole.
'On the other hand, males protest that even a tiny nick on their family jewels can leave them incapacitated.

'So which hurts more? Childbirth or getting kicked in the balls?', it ponders.
The video begins by explaining what exactly pain is.
It explains that pain is caused by nociceptors, a sensory neuron that responds to potentially damaging stimuli by sending nerve signals to the spinal cord and brain.
These neurons only fire pain once a certain threshold has been passed.

It continues: 'Testicles are covered in nociceptors, they are also attached to many nerves in the stomach as well as the vagas nerve which is directly connected to the brain's vomit centre.
'Because they aren't well protected, being hit there leads to nausea, high blood pressure, heart pain and sweating.'
The YouTube clip then goes on to explain that the process of childbirth mimics this pain.
It adds: 'Also consider that throughout the ages, women's hips have become smaller while babies heads have become larger.

'And not to mention that labour lasts 8 hours on average with a mixture of nausea, fatigue and pain plus tension and stretching.'
It then continues: 'So both obviously hurt and have a lot of mechanical stimulation sending messages to the pain centres of the brain but this is where it gets tricky because pain isn't just a physical response, it is partly subjective.
'This means that every individual perceives pain in a slightly different way and depending on alertness, mood and previous experiences, pain may affect you differently and that is why so many attempts to measure pain have failed.'

So that's why! Men often complain of feeling sick after being kicked in the private parts, which the video explains is because the pain receptors reach the vomit centre of the brain after a blow
The video concludes that both are equally as painful, therefore making it a tie.
'Suffice to say, both experiences of childbirth and getting kicked in the balls can hurt a lot. So we call this a tie.
'Apart from the fact that the experiences are very different and there's so many variables to consider, in some instances, a man could experience more pain than his female counterpart and vice versa.
'The main difference being that one results in a new born baby while the other results in the potentially decreased chance of having one,' it adds.
The conclusion: The scientific video concludes that both are equally painful, but one produces a child, while the other can hinder that
