Soon-to-be-parents will have a lot of questions to ask their doctors regarding their baby’s health and development. One question that many of them wish to ask is the gender of their baby.

There are many interesting myths that have been used to identify the gender of the baby. For instance, there is one popular myth that says if the belly is large, it is a boy, and a smaller belly indicates it is a girl.

But parents always want more concrete proof of their baby’s gender. So, they look for medical factors indicating their baby’s gender. One such medical factor is the size of the renal pelvis.

In this article, let’s discuss in detail how the prominence of the renal pelvis plays a role in identifying the gender of the baby.

The Link Between Gender and Renal Pelvis Size

The size of the renal prominence has often been associated with the gender of the baby. Some research shows that the renal pelvis size is bigger for male babies than for female babies.

Although a big renal pelvis may suggest a possibility of a male fetus, it is not a reliable indicator of gender. It shouldn’t be used as the only factor in establishing a baby’s sex.

It is crucial to remember that other factors, including the mother’s age, weight, genetics, and general health condition, might also impact the size and prominence of the renal pelvis.

What Does a Prominent Renal Pelvis Indicate?

For most pregnant women, a big and prominent renal pelvis can indicate she is having a male baby. But, as we have seen above, a prominent renal pelvis may indicate other issues as well.

It is important for Fertility Hospital and doctor to thoroughly check women who have a big and prominent renal pelvis A prenatal ultrasound scan and other tests should be done to evaluate the renal pelvis for any signs of complication. They are crucial to understand whether the condition will affect the mother and the baby.It is important for fertility hospitals and doctors to thoroughly check women who have a big and prominent renal pelvis

Can the Renal Pelvis Predict Your Baby’s Gender?

According to many studies, a prominent renal pelvis is one of the signs of having a male baby. But you should understand that this is not a foolproof method to assess the gender of the baby.

As we have seen above, a prominent renal pelvis may also indicate other issues. There are multiple factors that can impact the size of a renal pelvis.

While the renal pelvis can help predict the baby’s gender in the early stages of pregnancy, its accuracy decreases as the baby grows. Genetic testing is ultimately the best and most reliable approach to determine your baby’s gender.

Remember that a healthy pregnancy and childbirth are more important than the baby’s gender. Your baby’s health and normal development is more important than its gender. Although it can be exciting to learn your baby’s gender, you must remember that your child’s health comes first.

How Accurate is Renal Pelvis Measurement in Predicting Baby Gender?

By now, you should understand that a prominent renal pelvis does not guarantee the baby’s gender. Even in cases where a significant renal pelvis is found, gender prediction is only approximately 70% accurate.

Thus, for the most precise gender determination, doctors will combine several tests and methods.

The baby’s posture, the amount of amniotic fluid present, and the fetus’ gestational age are other variables that may affect the accuracy of renal pelvis measurement. It can be challenging to identify the gender based solely on this size when a prominent renal pelvis may be present in both male and female babies.

The Science Behind Fetal Gender Determination

The most common way to determine the gender of a baby is by going through several procedures and tests. Some tests your doctor may employ to identify your baby’s gender are

With a 99% accuracy rate, chromosomal analysis is the most reliable method of determining your baby’s gender.

It is important to remember that, in some cases, medical considerations do not call for fetal gender determination. For cultural or personal reasons, some parents decide to find out the gender of their unborn child.

Gender and sex are not the same thing, and a baby’s gender identification may not coincide with the sex to which they were assigned at birth.


As we have seen above, a prominent renal pelvis is not the only factor that determines the gender of the baby. While it may be a factor to consider, a prominent renal pelvis can be caused due to other reasons as well.

Consult your doctor and do a thorough checkup to identify the right cause of this occurrence and eliminate any complications that may arise in the future.


Widening of the renal pelvis, also known as hydronephrosis, is a typical finding on ultrasound scans carried out during pregnancy. It is a temporary issue and doesn’t cause severe renal or ureter problems.


The renal pelvis can vary greatly in size. The huge size is typical for many babies and falls within their usual range. However, an obstruction in the ureter or the reflux of urine into the kidney can also cause a dilated renal pelvis.

Many studies have proven that prominent renal pelvis is more prominent in boy babies and girl babies.

It has been observed that the kidney’s pelvic region contains a higher volume of urine. RPD stands for renal pelvis dilatation. This is frequently observed in babies growing in the womb.

At 20 weeks of pregnancy, you can expect the renal pelvis of the baby to be less than 7mm and less than 10mm at all other periods of pregnancy.
