Question (1/7)

When is the sex of your future baby determined?

From conception. After a few weeks.


The sex of your future baby is determined genetically from fertilization. When spermatozoa and ovules unite, two solutions are possible. If the egg is fertilized by a sperm with sex chromosomes XY ... it is a boy who will see the light of day. Fertilized by a spermatozoon with XX chromosomes, it will be a girl.
