Will I have a baby boy or a baby girl?

Your partner’s sperm determines whether you get a boy or a girl. Your ovule contains only the female X chromosomes, while a man has both the female X and male Y chromosomes. The spermatozoid reaching the ovule first determines whether your baby will be is a boy or a girl. Spermatozoids carrying the female gene are larger and swim slower than the male ones. The male sperm cells are thus quicker in the egg than the female.
