If you have sex and conceive successfully, you can check the astronomical phenomena, i.e. the constellation in which the moon falls at that time.
If the moon falls in a masculine sign which belongs to air or fire, such as Aries, Gemini, Leo, Libra, Sagittarius and Aquarius, you will be more likely to have a baby boy.
If the moon falls in a feminine sign which belongs to water or earth, such as Taurus, Cancer, Virgo, Scorpion, Capricorn and Pisces, you will be more likely to have a baby girl.
It is said that this prediction method of baby gender is about 95% accurate! What's more, it is pretty easy to figure out time since the moon passes a constellation in about 2.5 day.
