What are the significance/advantages (if any) of two testicles?

Sorry for the DP, all!

What’s wrong with Rico’s pronoun antecedents? “One of my best friends” is the antecedent for “he” (in both places), and “he and his wife” is the antecedent for “they”.

I beg to differ. In this case it would have been advantageous (for the species) if he had had only one and thus disqualified himself from propagation.

Which child is the antecedent for “one”?

How can you tell which one is the spare?

The advantages, in evolutionary terms of having two become evident in every case where someone ends up having only one. Other than that, no big deal.

My WAG is that this happened during the '60s or '70s (they adopted an American-Vietnames orphan), long before the internet. And back then it was very difficult for most men to discuss subjects like this with their doctors (it’s still a touchy subject for a lot of guys). So I’d be very reluctant to call the guy stupid.

The best reason for having two: they’re more fun to play with than just one. Same as nipples.

I think it is for balance. I know that I couldn’t walk straight if I didn’t have one to counterbalance the load of the other.

My parents used to have a dog with only one testicle. And yes, it walked crooked.

…yet only one penis…

[Dr. Evil] One, two… and three. Okay. [/Dr.E]

And two hands…

[big red one] That’s why God gave you two! [/big red one]

I believe what you mean to say here is that they had a dog with only one scrotal testicle. The second was likely either inguinal or abdominal;.

It’s the one that’s tucked up underneath the folds of skin. Stick a crank in yer bum and wind slowly counterclockwise-it’ll soon be visible as the cable lets it down. Once the spare testicle is installed, ensure that the nuts are tight. :stuck_out_tongue:

You adjust. Trust me, I know what I’m talking about.

Hey Tristan;
If you don’t mind: Lefty or righty?

My grandmother once told me that, according to one of her HS teachers, a goat bit one of his testicles off when he was trying to urinate into it’s mouth as a teenager.

You know, I’m not really sure. I think what I have is my left testicle.
