Is it possible to choose the baby’s sex through sexual positions? Science clarifies the myth
For generations, various popular beliefs have circulated about how couples can influence the conception of a girl or a boy. Among the most widespread myths is the idea that certain positions during sexual intercourse can determine the sex of the future baby. However, from a scientific perspective, it is essential to clarify what truth there is in these claims.
The reality behind the Shettles method
Much of these myths are based on the well-known Shettles method, popularized in the mid-20th century. This theory suggested that Y-chromosome-bearing sperm (associated with the male sex) were faster but less resilient, while X-chromosome-bearing sperm (associated with the female sex) were slower but had a greater survival capacity.
Based on this premise, recommendations were disseminated that suggested:

The biology of fertilization is a much more complex and random process than these popular theories suggest.
It is important to distinguish between identifying the fertile window to achieve pregnancy and the unsuccessful attempt to choose the baby’s sex through home methods or specific positions.
What really determines the baby’s sex?
The sex of the future baby is defined at the precise moment of fertilization. The egg always contributes an X chromosome, while the sperm can contribute either an X or a Y chromosome. The resulting combination—XX for a girl or XY for a boy—is a natural process where the sexual position adopted has no influence on which sperm will manage to fertilize the egg.
Beyond the myths: Health recommendations
There are other myths that suggest changes in diet, the use of lunar calendars, or the alteration of vaginal pH. Alofoke Deportes reminds its readers that many of these practices, especially those involving the use of chemical substances or vaginal douches, can be harmful to reproductive health. The only way to determine sex with precision is through advanced medical procedures, such as in vitro fertilization with genetic testing, which are carried out under strict ethical and medical criteria.
In conclusion, if the goal is to start a family, it is highly recommended to maintain healthy lifestyle habits, understand the menstrual cycle, and consult with healthcare professionals. The pursuit of pregnancy should focus on the well-being of the couple, setting aside false expectations regarding choosing the baby’s sex through methods without scientific backing.
