Position of the placenta and gender of the baby: will it be boy or girl?

According to some theories, it is possible to predict the sex of the unborn child based on the position of the placenta. Is it reality or false myths? Read to find out!

After confirmation of pregnancy , one of the first curiosities of future parents is to know if the baby on the way will be a boy or a girl . But how to find out as soon as possible? On the web there are many theories about it, scientific and otherwise, and some of these concern the position of the placenta .

In particular, it is believed that in the case of a posterior placenta, it is more likely to have a boy , while with an anterior placenta, it is more likely to have a girl .

According to another hypothesis, however, it is the side on which the placenta is inserted that indicates the sex of the baby : if it is on the right , the future baby will be a boy , while if it is on the left , a girl will be born .

But what is meant by posterior, anterior or lateral placenta ? And what is true in these theories?

Location of the placenta: what it is and how to find out

The placenta is a vital organ for the development of the baby, which adheres to one of the walls of the uterus and connects to the fetus via the umbilical cord .

To perform its functions, the placenta can insert itself anywhere in the uterine walls, including:

  • posterior wall (between fetus and back), for which we will speak of posterior placenta ;
  • anterior wall (between fetus and belly), for which we will speak of anterior placenta ;
  • lateral wall (right or left), for which we will speak of lateral placenta .

The position of the placenta is evaluated through the usual ultrasound scans that are performed during pregnancy. These tests, in fact, also serve to evaluate the correct insertion of the placenta.

Posterior placenta and anterior placenta: male or female?

According to one of the theories mentioned above, women with a posterior placenta are more likely to be pregnant with a boy . Conversely, when the placenta is anterior, the birth of a girl would be more likely .

This hypothesis was tested by a 2014 study , which analyzed the placenta position of 200 pregnant women. The results showed the presence of an anterior placenta in 72.8% of female newborns, compared to 27.2% of male newborns.

This investigation would therefore seem to support this theory. In reality, however, a single study conducted on such a small number of cases is not sufficient to support this hypothesis . For this reason, the authors concluded that, although a significant association between placenta position and baby sex has been found, further studies on larger samples of women are needed to draw reliable conclusions.

To date, therefore, we can say that the research does not support this theory .

Right and left lateral placenta: male or female?

According to the so-called Ramzi method (named after the doctor who proposed it in 2011), when the placenta is inserted on the right side, it is more likely to have a boy , while when it is on the left side, it is more likely to have a girl .

This theory, however, was not published in a scientific journal, but on a blog ( Also, the article detailing it has been removed.

Currently, research does not support the Ramzi method, which is considered to have no scientific validity .

Is there any way to know for sure the sex of the baby?

Second trimester ultrasound , also called morphological or structural ultrasound, is a reliable method of knowing if the ribbon will be pink or blue (provided the baby is cooperative!)

Furthermore, some tests performed to investigate the presence of chromosomal abnormalities in the fetus are able to identify the sex of the unborn child early:

In conclusion

Trying to predict your baby’s gender based on these theories or other popular beliefs can be a fun pastime. These methods, however, have no scientific validity.

For this reason, before choosing the future baby’s layette or the color of the bedroom, it is better to have a little patience and wait for the outcome of a reliable test .
