Never heard of a Q-tip that produce sperms so no, unless a guy put some on there.
Pollen are male sex cells. So they contain sperms.

so there is a higher chance of fertielisation of the female egg
That is a good question. Both egg and sperm has the same number of chromosomes. But then the size of the egg is very big compared to sperms. Here the egg has lot of food material stored in them. that is necessary for cell multiplication after the conception. sperms has to run fast for fertilization. You can not run fast with some heavy weight on your back. Also the number of the sperms is very high and so many big sperms will create the problem of accommodation in the semen.
Separation of sperms from semen can only be done in a lab so no.
They have strong tails for swimming
Brazil have produce so many thing.
Because most of the sperm cells die on their journey to the egg.
Absolute answer is unknown. Easiest answer is to improve the chances that one is able to get the job done. Why does an Oak tree put out so many acorns? A dandelion flower with it's hundreds of seeds. Nature repeats what works, it's all to make the chance of reproduction greater.
