it is completely impossible as far as i know to up your chances for having a boy or girl when just having regular sex. it's a 50:50 chance like red or black on roulette. but some doctors know how to use something called a centrofuge (spelling might be wrong i haven't spelt that word in a while aha) this spins the sperm sample around at high speeds and separates the sample out by wieght. female sperm cells as far as i know should weigh more because the x chromosome is larger than the y. so if you have an x sperm cell it should be lower in the tube since they would weigh more. and note that the woman gives one x herself and sperm and egg cells are something called haploid (they are like halves) don't try to temp fate though you don't know what fighting the universe has in store.
