How you can choose sex of your baby​

Some couples dream of being able to choose the sex of their children. While some methods have been scientifically validated, keep in mind that no technique is truly 100% reliable.

Did you know ? A baby's sex is determined at conception, when the egg and a sperm unite. At this time, the mother's X chromosome is associated with either an X chromosome or a Y chromosome, brought by the father's sperm:

• An alliance of XX chromosomes gives birth to a girl,
• An XY chromosome alliance to a boy.


Carriers of the X chromosome, which will lead to the formation of a daughter embryo, are slower and more resistant. So to have a baby girl, you have to have sex a few days before (often between 3 to 5 days) before your ovulation date.

Carriers of the Y chromosome, on the other hand, are faster but less resistant. So to conceive a baby boy, it is better to have sex on the day of ovulation or 1 day before or after the day of ovulation


To have a girl, the mother must have a diet rich in calcium and low in salt. Conversely, to have a boy, a salty diet devoid of potassium is recommended.

A specific diet of the mother could slightly modify this pH and promote the passage of this or that type of sperm:

• The daughter diet, low in salt and rich in calcium, would acidify the mucus, thus only guaranteeing the passage of gametes carrying the X chromosome, which are more resistant. So eat dairy products, green vegetables, fish to give birth to a baby girl.
• The male diet, rich in sodium and potassium, changes the pH less. With the latter, all the spermatozoa support the alkalinity of the vaginal environment and the fastest will therefore be favored for fertilization. On the menu: delicatessen, meat and fish would therefore be the guarantors of a male filiation.
