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.

Do you know ... your due date already?

If you want a boy, you should try to have sex during or right after ovulation. If you want a girl you should try to have sex just before ovulation. To help you spot the right timing of your ovulation, you can order an online ovulation test or try our free online pregnancy and fertile period test.

Go here for fun old wives' tales and myths about your baby’s sex.

This traditional Chinese table will show you whether you are expecting a girl or a boy based on your age and the month of conception:
