The Chinese Gender Chart is based on the mother's lunar age and the lunar month when the baby is conceived. Many people criticize the chart is illogical as fathers do not involved in the gender of their offsprings at all. Scientists tell us that a baby boy receives an X chromosome from his mother and a Y chromosome from his father while baby girls get an X chromosome from each parent. So it is most likely that the father control the baby gender.

Dr. Anil Maheshwari from India, however, has taken a different view. In his article "Myth: Sex of the baby is chosen by the male. Reality: Sex of the baby is chosen by the female", he expressed that when the ovum membrance is positively charged, it will attract the sperm carrying X chromosome and a baby girl is produced. and when the membrane is negatively charged, it will attract the sperm carrying the Y chromosome, and a baby boy is produced. He conclued that

"... so would it not be most appropriate to say that it is the female that chooses the sex of the baby (by virtue of selecting which sperm to mate with) and the male only determines the sex of the baby after conception."

Believe it or not, there are three more “secret” gender selection methods found from the ancient Chinese Literatures. Gladly, father is involved in some of them.

1)	Method :	68 + the month when the baby conceived - Age of the mother when the baby conceived
	Conclusion :	If the result is a single number, then it is a boy. A even number will be a girl.


2)	Method :	(Age of the father when the baby conceived + age of the mother when the baby conceived + the month when the baby conceived) divided by 3. Ignore the number after the decimal point.
	Conclusion :	If the result is a single number, then it is a boy. A even number will be a girl.

3)	Method :	Baby conceived in an odd month (1^st, 3^rd, 5^th, 7^th, 9^th, 11^th month)
	Conclusion :	If age of the father at conception is an odd number and age of the mother at conception is also an odd number, you will get a boy. If age of the father at conception is an odd number and age of the mother at conception is an even number, you will get a boy. If age of the father at conception is an even number and age of the mother at conception is an odd number, you will get a girl.

	Method :	Baby conceived in an even month (2^nd, 4^th, 6^th, 8^th, 10^th, 12^th month)
	Conclusion :	If age of the father at conception is an even number and age of the mother at conception is also an even number, you will get a girl. If age of the father at conception is an odd number and age of the mother at conception is an even number, you will get a girl. If age of the father at conception is an even number and age of the mother at conception is an odd number, you will get a boy.
*Note that all the above calculations are based on lunar month and age. Check out the lunar age calculator to find out the right lunar age and month.* Again gender selection by any of the ancient Chinese methods may only be part of the factors to determine the baby sex. To get a high successful rate, diet before pregnancy, date of intercourse and intercourse position should also be considered.
