When does the gender of the fetus appear?
Revealing the gender of the expected baby is a pivotal and exciting moment in the pregnancy journey that ends when precise scientific tools reveal that little secret to you.
So if you want to know when the baby's gender appears?
When does the fetus' reproductive organs begin to form?
Sperm contains the sex chromosome that determines your baby's sex at conception
- X chromosome for a girl.
- The boy's Y chromosome.
The internal genital organs of boys and girls are similar until the ninth week of pregnancy, but they begin to differ from each other in the eleventh week.
The external genitalia begin as multiple small bumps forming between your baby's legs in the fourth to fifth week of pregnancy, and around the same time the internal genitalia form a bulge of tissue on either side of your baby's abdomen.
Growth of male reproductive organs
The boy's testicles (the two glands responsible for producing and storing sperm) begin to grow six to seven weeks into pregnancy.
It continues throughout pregnancy, reaching about 3.5 cm at birth.
By the twentieth week, the development of the male external genital organs is complete, as the testicles begin to descend into the scrotum, but they do not reach their final position until late in pregnancy (i.e. around the twenty-fifth to thirty-fifth week).
Growth of female reproductive organs
The external genital organs of the female and the male are similar until the eighth week of pregnancy, and then the fleshy coverings in the genital area begin to form, either the labia majora, or the scrotum, and the penis.
The girl's ovarian follicles begin to form around the twelfth week, then by the thirteenth week the ovary's growth inside the body is complete, and the reproductive bud between the girl's legs turns into the clitoris.
In the twentieth week, the development of the girl’s reproductive system is complete, and her ovaries become filled with a lifelong reserve of between 6 and 7 million eggs.

When does the exact gender of the fetus appear?
If you would like to know exactly when the fetus's sex appears before birth?
- Ultrasound examination is one of the most common methods and can be used to determine the gender of the fetus, usually at about 12 to 14 weeks.
- NIPT test, which can be performed as early as 9 or 10 weeks of pregnancy.
- Chorionic villus sampling (CVS), this test is performed in the advanced stages of pregnancy.
The NIPT and CVS tests are more accurate than the ultrasound examination, because they depend on the fetus's DNA.
However, there may be some difficulties that may affect the ability to determine the fetus’s sex as early as 12 weeks, such as:
- The fetus must be in a good position;
- The mother's weight, as the mother's weight may affect the accuracy of the image.
- The quality of the device used to determine the sex of the fetus.
Methods for determining the sex of the fetus
There are many tests that may help you determine the sex of the fetus, but although they are reliable tests, they are not suitable for everyone, and some may carry significant risks.
Determining the gender of the fetus is a secondary benefit of these tests, because they aim to know other information that is more important for the health of the fetus.

This test is accurate to determine the sex of the fetus, but it may involve some risks, as some women may suffer from the following
- Contractions.
- نزيف.
- Leakage of amniotic fluid.
- Miscarriage.
- الولادة المبكرة.
So your doctor may advise you to undergo this test if you are over 35 years old, or have a family history of chromosomal disorders.
- Amniocentesis
Amniocentesis is a genetic test similar to chorionic villus testing.
- متلازمة داون.
- Spina bifida.
- Other genetic conditions.
This test is usually done at weeks 15 and 20, but may also be done later.
This test is available to all pregnant women, but it is usually only used for women who are at high risk of genetic and chromosomal problems, because it may involve a small risk of miscarriage.

- The child is in an uncomfortable position, such as with his legs closed, which makes it difficult to clearly see the gender of the fetus.
- The mother's weight, which may affect determining the gender of the fetus.
The difference between two-, three- and four-dimensional ultrasound in determining the gender of the fetus
Ultrasound is known as ultrasound, and these waves have revolutionized the world of medical diagnosis, especially in the field of prenatal care.
This is done by touching the sound waves to the body's tissues, fluids, and bones, then bouncing them off as echoes, and then the transducer receives those echoes and turns them into images that are displayed on a video screen.
Ultrasound is a safe, painless way to see inside the uterus and the fetus.
The difference between two-dimensional, three-dimensional, and four-dimensional sonar lies in the following table
| ثنائي الأبعاد | ثلاثي الأبعاد | Four-dimensional | |
| التعريف | Two-dimensional ultrasound is the most common and conventional.
It is also used for routine checkups throughout pregnancy. |
It is an evolution of 2D ultrasound, as it provides an additional dimension to the images. | It's basically a 3D ultrasound, but moving. |
| the pictures | Produces flat black and white images that allow a clear view of the fetus's skeleton and internal organs. | It takes multiple 2D images from different angles, and presents a 3D stereoscopic image.
It allows a more detailed view of body parts and facial features, such as

They bring life to still images from 3D imaging, as they provide instant moving images of the fetus inside the womb, e.g

3D sonar is used in the following

It also gives parents a realistic view of their child's appearance. |
Many parents resort to 4D ultrasound imaging
It is also used to monitor fetal movement. |
Tips for preparing for fetal gender testing

- You should drink one liter of clear fluids about an hour before the gender test.
