Yes, it is likely to have at least some residual function or role in the physiology of the whale. Even wisdom teeth in humans, although often detrimental in effect and hardly unmissable, can be said to have a role in our digestive tract. What makes it evidence for common descent is not any presumed function or lack thereof, but the fact that it is morphologically what we should expect it to be if whales descended from land mammals.
it has 1200000000000000000 babies a week. tmd

No the reproductive cells of a whale are not much large then those present in Humans. The sperm cells even in the large sperm whale would still be too small to be seen by the naked eye.
