      Not much more to tell. I suppose it’s worth mentioning that chimps have larger balls, and produce a lot more sperm than humans do. Their swimmers are also stronger and much better at travelling through mucus. This is because humans became serially monogamous, rather than 1 male tops all and leaves his children to figure out how to avoid inscest. Our sperm just isn’t used to competition anymore.
