The scrotum
Regardless of whether you are male or female, there has come a point at which you have looked at the male sexual anatomy and asked yourself the obvious question: “What is going on here?” Just look at it—the design is ridiculous. The two testicles are hanging in a little sack called the scrotum, so they are out in the open and completely exposed.
If man is created by an Intelligent Designer, then why in the world would he design human males like this? Why aren’t the testicles packaged neatly inside the body like every other important organ?
If you are a male, you know about the several problems that go with external testicles:
- It can be uncomfortable to run because the testicles have a tendency to flap around. This is why male athletes wear jock straps.
- Because they are outside and unprotected, the testicles are quite sensitive to pain. Any male who has ever been “kicked in the balls” or fallen in the wrong way on his testicles knows how excruciatingly painful it can be.
- Because there are loose flaps of skin involved, you get problems like chaffing, jock itch, etc. that develop in and around the scrotum.
Anyone who looks at the design of the testicles and the scrotum can see that there are major flaws. Why are the testicles designed this way?
The testicles hang in a sack outside of the body on most mammals for a very simple reason. The ideal temperature for sperm production happens to be about three degrees Celsius lower that normal body temperature. By hanging the testicles in an external sack, the testicles can more easily maintain this lower temperature. Two types of mammals solve the temperature problem with something other than an external sack: cetaceans (dolphins, whales) and seals. They compensate for the temperature problem with elaborate blood circulation schemes to keep the testicles cool.
If an Intelligent Designer created the human body, the obvious question that you have to ask yourself is this: Why didn’t he simply design the testicles so that they function at the normal body temperature? Why in the world would an Intelligent Designer make them temperature-sensitive? If the testicles functioned at normal body temperature (instead of three degrees cooler) then the testicles could be inside the body like every other organ.
Why create such a ridiculous design?
What if we hypothesize that there is no Intelligent Designer? In that case, the human body was designed by a natural process. The fact that the sperm-producing organs are temperature-sensitive is an accident of that natural process. The problem was solved by nature by hanging the testicles of most mammals in a little sack outside the rest of the body. In that case, this whacky design makes sense.
I agree - no Intellegent Designer created this world...
