Choosing the sex of your child would be possible thanks to the programming of sexual relations; This is the conclusion reached by Drs Landrum Shetlles and David Rirvik, authors of the book “Choosing the sex of your child”, a conclusion based on the differences between X sperm (girl) and Y sperm (boy).
According to studies by these two American biologists, scheduling sex at the right time would make it possible to choose the sex of your baby. Indeed, this theory is based on the speed and resistance of X sperm (girl) and Y sperm (boy) which will fertilize the egg. For this, you must know your ovulation day and have sex according to your preference, boy or girl!
To know the exact time of your ovulation, you need to “study” your uterus, record your body temperature daily, and find out how long your menstrual cycles are.
How to have a boy?
According to the research of Dr. Shetlles, Y (boy) sperm are smaller, faster and less resistant than X (girl) sperm. They need the least harsh “environmental” conditions possible, they arrive first and die quickly.
So, if you prefer to have a boy, the sperm must arrive in the tube at the same time as the egg, that is, when you ovulate. In this case, you should have sex within 12 hours of ovulation, but only once. If you have sex again, protect yourself with a condom.
During ovulation, vaginal and cervical (cervical) flow is alkaline, a condition more favorable for the movement of sperm, but particularly favorable for Y sperm (boy).
How to have a girl?
X (girl) sperm are larger, stronger and slower than Y (boy) sperm. They are more resistant in an acidic environment and in the face of relatively unfavorable conditions. In addition, since they are stronger, they can wait for the egg for a few days.
That’s why, if you want a girl, Doctor Shetlles recommends that you have sex between your period and ovulation, and this up to 2 days before ovulation. Thus, the Y (boy) sperm “die” and the egg is then faced with a higher concentration of (girl).
In addition, before ovulation, vaginal secretions are more acidic and X sperm (girl) will have a better chance of surviving and fertilizing the egg than Y sperm (boy).
How do you recognize the time of ovulation?
- By observing the changes in your cervical mucus.
On days when you are not fertile, you secrete little cervical mucus; furthermore, it is white and has a sticky texture. 2-3 days before ovulation, your flow changes. It is abundant, transparent and shaped like threads (one could compare it to egg white). The most fertile period in women begins on the last day of this mucus. Usually, this egg-white-like mucus goes away the day before ovulation or the day you ovulate.
- By measuring your body temperature.
You should take your vaginal or rectal temperature every morning of your menstrual cycle when you wake up. The day on which the temperature rises by 2 to 3 decimal places (0.2ºC to 0.3ºC) from the average temperature during the cycle corresponds to the day of ovulation.
