HOW TO SELECT YOUR BABY'S SEX.
Sperm cells are either X or Y. The Egg cell is always X. If X-Sperm cell meets the egg(X) the baby will be a Girl (XX). If Y-Sperm cell meets the egg(X), the baby will be a Boy (XY). The Y-Sperm cells move fast but die fast (its lifespan is about 24hrs). X-Sperm cells move slowly but survive longer (up to 3-4days). Therefore, if you have intercourse some days before ovulation, most of the Y-Sperm cells would have died leaving mostly X-Sperm cel ls to fertilized the egg Here's a simple way to calculate your ovulation period. 1. From the first day you see the blood of your period. 2. Pick up a calendar and count 15 days including the first day of the blood stain. 3. Mark the 15th day with a pen. 4. Mark 3 days before the 15th day, and mark 3 days after the 15th day. 6. You will notice you have 7 days marked. These 7 days are your ovulation/fertile days also known as unsafe period. That is if you have sex on any of these days, then you have 98% chances of being pregnan
