HOW TO CHOOSE YOUR BABY'S SEX

Male sperm cells are either X or Y. Female egg cell is always X

If X-Sperm cell meets the egg (X), baby will be Girl (XX). If Y-Sperm cell meets the egg (X), baby will be Boy (XY). You can select the sex of your baby
#MasculinitySaturday Image X-Sperm cells move slowly but survive longer (up to 3-4days).

Y-Sperm cells move faster but also die faster (lifespan about 24 hrs).

So if you have sex some days before ovulation, most of the Y-Sperm cells would have died, leaving mostly X-Sperm cells to fertilize the egg.
