Lol. Reminds me of this game I played where the protagonist’s dad got one of his testicles blown off, and in the ending of the game when it was suggested to him to go to the hospital he just goes, naaah I’ll staple it up when I get home. Hell you only need one, anyway.
We seem to have one or two of body parts. Even our single nose has two nostrils. Exterior single body parts tend to be on our middle, like the nose, mouth, and belly button. Since symmetry is pleasing to the eye, maybe that is part of the explanation. Although, I am not sure I would say testicles are pleasing to the eye. Having two does provide a back up, just like two ovaries (testicles are the same embryonic tissue as ovaries) and two kidneys, and even two eyes and ears, and so on.
Since reproduction is so important I can understand having two – one as back up. Three or more only offers marginal back up beyond two. Any physical event big enough to take out 2 will likely take out all 3. Any disease that infects two will likely infect 3.
Also they are not so large so they’re easy to package and store:
“Take two, they’re small.”
Hey, did I just inadvertently explain why we have one penis? :-)
We have many paired organs. Even our brains have two parts, though they are connected by the corpus callosum, which allows the hemispheres to communicate with each other. Survivability and the likelihood of reproduction are increased because of duplication.
Well, there was this guy that had three testicles, and when women felt that, they tended to freak out. He got very depressed and went to the doctor to see if they could remove one of them. The doctors really didn’t want to, because of the risks involved, so they sent him home to think things over and consider the risks. He left the doctors office and got a cab. The cabbie noticed he was really bummed and asked what was wrong. The guy responded between the two of us we have five testicles. The cabbie looked up and said what you only got one?
@Mimishu1995 Yep, having a third might make walking more difficult. Instead of a side-to-side gait, you would probably have more of a fore-aft one and, if they all got to swinging in sync. it could throw off your stride. @SymbelineThis one is for you. @whitenoise , @Adirondackwannabe, @janbb :) @ninjacolin why not? We have monotheism with a holy trinity to cover all the bases. @JLeslie Are testicles pleasing to the eye. Another question for another day? @LuckyGuy is that the engineer talking? And, one penis vs two benefits or disadvantages yet another question for another day! @Espiritus_Corvus and bicycle crossbars on bikes designed for males but not females. Are we masochistic or just have a warped sense of humor? @Bill1939 but how do we counter the argument put forth by Robin Williams that ”“God gave men both a penis and a brain, but unfortunately not enough blood supply to run both at the same time.”
And speaking of two testicles… Most of you know I have friends in a Prostate cancer support group. One of the guys had an awful operation and had his bladder sphincter, prostate, testicles… all removed. Awful… I can’t imagine.
He had an artificial sphincter installed for bladder control and another pump installed so he could get an erection. The control bulbs fit inside Mr Wrinkles. Squeeze the right bulb to get an erection. Squeeze the left bulb to urinate.
He said he is going to get a tattoo in the appropriate area that says “Come and Go”. :-)
It’s a good thing humor is not stored in the prostate.
One of the earliest evolutionary ancestors was a flatworm. Every bilateral creature since then is thought to be descended from this one ancestor- that means fish, insects, reptiles, birds, mammals, etc. So we have two eyes, butterflies have two wings, and guys have two balls.
