No, the other way around. Higher testosterone levels will increase sperm. A differing view is that testosterone is absorbed by some soft tissues in the body. it is a fact that women do get a boost in Testosterone from semen during sex, They also pick up testosterone from deep (french) kissing a man. So if that is so & it is, Semen in the mouth will allow for the absorption of Testosterone. Swallowing, probably not, the acid in the stomach will break down the Testosterone.
Vitamin b12, Tyrosine, and L-dopa will boost energy levels.

You Don't Do Anything That's How Semen Smells :)
The same as anything else you digest
There is the word, "Boost", and there is the word, "Blastoff", or "Takeoff", but no word to boost off, since that really doesn't mean anything.
Serotonergics (drugs that boost levels of the brain chemical serotonin)
Unless the semen had managed to get in between the primer and firing pin - and even then it wouldn't do anything - no.
No it won't do anything, but why would you?
If you swallow your own semen, then no, you can't get anything new. It's quite safe. It's fairly safe, too, to swallow someone else's semen.
Yes you can you just as long as the car is running you can boost just about anything from a truck to a motorcycle
Yes, semen can have a sticky texture due to its protein and sugar content. It can vary in consistency depending on hydration levels and overall health.
