There is one more point you didn't mention: the pain of giving birth.

Now, as a man, I'm unqualified to comment to that, but I have occasionally been confronted with women saying that giving birth hurts more than a kick in the (male) groin.

I had recently the chance to carefully consider this fundamental issue, for which I consulted a bottle of Spanish Red, as I usually do, when contemplating globally important issues.

My conclusion is, the claim is incorrect. It is based on the observation that I have frequently encountered women say things like "let's have another baby" (not to me of, course) whereas I have never come across a man saying "let's have another kick in the b…ls"
