male's loyalty / faithfulness to his partner is related to his testes size??

I know talking about testes size is weird ..... (I promise you i won't get mad  if you decide to stop reading now :)  but if you continue reading....i think you will find this interesting.


How faithful one is to his partner depends on MANY factors and I do not know all of them ( I actually hardly know any).   I am going to discuss one factor today :)  This factor might not apply to everyone, every time, but it is definitely an interesting one to think about.

One's testes size....(i  know this is kind of private... Fine, i admit this is super private)  is related to how faithful he is to his partner?? HOWWWWW ( you might ask....don't rush me, i will tell you in a bit....).  

In order to relate one's testes size to his faithfulness, i am going to tell you a little study i learned in my third year class AGAIN.   Some researchers measured testes size of gorillas, chimpanzees and human.  The researchers found proportionally, gorillas have the smallest testes while chimpanzees have the biggest testes.  One of the suggested reason for gorillas having the smallest testes relative to their bodies size is gorillas are very monogamous.  The male gorilla can be quite certain his partner will not mate with other males.   Animals in the wild do not waste energy on unnecessary things. Making sperm is energy costly.  Knowing the female partner will not have other males gorillas' babies, the male gorilla then can spend more of his energy in body building to protect his family, forage for food and build a safe living environment instead of making sperms. Since sperms are produced and stored in the testes, and only one sperm is required to fertilize an egg, male gorillas don't need to make a lot of sperms to produce the next generation.   Hence they do not need big testes to make and store a lot of sperms.    

On the other hand, Bonobo, a species of chimpanzee is famous for its high level of sexual activities. I didn't make this up, i have proof and here it is ( http://en.wikipedia.org/wiki/Bonobo).  Since bonobo are polygamous (meaning they have many partners ), whichever males' sperm reaches the female egg first, then that male can successfully reproduce. (Can i tell you something interesting?  Well i am going to tell you anyways.  I have heard that if one bonobo gives another bonobo a banana, the receiving banana banobo will have sex with the banana giving bonobo to show its appreciation.   Or if one bonobo scratches another bonobo's back, they will again have sex to show its appreciation)  Being in a polygamous society means there is a strong sperm competition.  The more sperm a male can make, the more female he can attempt to fertilize.   Bigger testes can mean more sperms can be produced and stored.  This suggests male bonobos with bigger testes can fertilize more females and reproduce more.  

Since human male testes size falls in between gorilla and chimpanzee, does that mean human is partly polygamous and partly monogamous by nature?? Can I ask a question then ??  If that is true, if one has smaller testes, does that mean his is more faithful to his partner by nature?

Anyways....i dont think there is a cause and affect relationship between male's loyalty to his partner  and  his testes size.  There might be a tiny correlation though, non?? ( what do you think?)
