The seeds would not be their if the plant didn't get polenated. It takes polenation to make the seeds, not to make them useable. If you grow those seeds and pull all of the males you will endup with sinsemilla (seedless bud). If you leave the males they will release pollen and polenate the females, producing more seeds. Most people want the most potent bud possible so they pull the males. hope this helps..
