Gender Selection Methods by Intercourse Timing: Review of Published Scientific Articles Can you choose the sex of your baby? Many couples are interested in gender selection methods, particularly the Shettles Method. But is there any scientific evidence that you can actually choose the sex of your baby using this method? To answer this question, we have conducted a brief review of the scientific literature in this field. Shettles published an article called “Factors influencing sex ratios” in the International Journal of Gynaecology and Obstetrics.
Since that time, many researchers have sought to test Shettles theory. A review of the published scientific literature in the field of gender selection and prediction, however, yields conflicting claims. The majority of studies find little or no correlation with timing of intercourse and the sex of offspring. Some studies actually claim that the opposite of Shettles’ theory may be true. There has been some speculation, however, that another factor may play a role in gender determination.
Most parents-to-be who are trying to conceive would be delighted to be expecting a child of any gender. Still, interest in gender selection and prediction abounds for a variety of reasons. And it is not hard to find parents who claim that one technique or another was successful for them. Nonetheless, the majority of scientific studies suggest that there is no clear evidence that you can use intercourse timing to increase the likelihood of conceiving a particular gender. Without any clear evidence that you can dramatically increase the odds of conceiving a boy or a girl, limiting intercourse within the fertile period is not recommended for couples who wish to conceive quickly or those who are experiencing difficulty conceiving.
