How to Conceive a Boy – How to Conceive a Girl

Do you want to know a method to conceive a child? Or do you prefer a girl? We present you the Shettles and Rorvik method, which defends the possibility of determining the sex of the baby according to the day of fertilization.

You are thinking about getting pregnant and you would like to know some method to conceive a boy or a girl. You are in luck! Choosing the sex of the baby by programming sexual intercourse is possible: is the conclusion of doctors Landrum Shettles and David Rorvik, authors of the book ‘How to choose the sex of your baby’, based on the differences between the sperm X (girl ) and Y (boy) sperm.

According to studies by these American biologists, scheduling sex for just the right time would allow you to choose the sex of the baby. For this, it is necessary to know the moment of ovulation and to program sexual relations according to preferences. It is necessary, therefore, that the woman knows how to recognize the moment of ovulation, noting the basal temperature every day and keeping track of the exact days that her menstrual cycle lasts. This theory is based on the speed and strength of the X (girl) or Y (boy) sperm, which will fertilize the egg.

How to Have a Boy

According to Shettles’ research, Y (boy) sperm are smaller, faster, and weaker, require minimal adversity, arrive first, and die quickly. Therefore, if you prefer to have a child, the sperm must reach the tubes almost simultaneously with the egg, that is, at the time of ovulation.

  • In this case, sexual intercourse can be started 12 hours before ovulation.
  • Also, the couple should have sexual intercourse during the 12 hours of ovulation, preferably only once. If they have relationships again, they should use a condom.
  • During ovulation, the vaginal and cervical fluids (cervix) are alkaline, a condition that makes the arrival of sperm more favourable, but is especially favourable for the Y (child).

How to Have a Girl

The X sperm (girls) are bigger, stronger and slower, more resilient in adverse conditions or moderately acidic. In addition, they are more durable and can wait a few days for the egg.

  • Therefore, if you want to have a girl, Shettles recommends that the couple have intercourse after the end of the menstrual period, at least one day later, up to two days before ovulation.
  • In this way, the sperm Y (boy) “die” and the egg meets more sperm X (girl).
  • In addition, before ovulation, vaginal secretions are more acidic and the sperm X (female) will have a better chance of surviving and fertilizing the ovule than the sperm Y.

How to Recognize the Moment of Ovulation

We list some factors that will allow you to recognize the moment in which you are ovulating.

  • Observe the changes in cervical mucus. On days when the woman is not fertile, cervical mucus is sparse, whitish, and sticky in texture. While 2 or 3 days before ovulation the flow changes and is abundant, transparent, and forms threads (similar to the egg white). A woman’s most fertile period begins on the last day that she has this mucus. Usually, egg white-like mucus goes away the day before ovulation or the same day.
  • Measure your basal temperature. You should measure your vaginal or rectal temperature each morning of the cycle when you get up. The day that the temperature rises by two or three-tenths of a degree from the average are the day of ovulation.
