Determine the gender of the fetus

Parents focus on determining the gender of the fetus early in pregnancy. This is in order to be able to choose the name, and prepare all its requirements and needs. As for the doctor, he is interested in determining the gender of the fetus in order to reassure his health, and to detect any possible diseases related to sex, such as congenital adrenal hyperplasia, and hemophilia.

The appropriate period for determining the gender of the fetus is after the end of the twelfth week of pregnancy, that is, after the growth of the external genital bud has completed, and its appearance is clearly visible to the outside. The error is estimated at 40%.

How does the doctor know the gender of the fetus?

genital bud shape

The doctor usually identifies the sex of the fetus by examining the ultrasound, detecting the external genitalia, and noting its shape, size, and the main differences between the shape of the female genital bud and the male genital bud, which can be listed as follows:

  • Male genital bud: The direction of the male genital bud is forward and upward, taking a position similar to the horizontal position, and doctors liken the shape of the male genital bud to the shape of a turtle; Where the penis protrudes in the form of a turtle’s head, while the testicles appear in the form of a turtle’s house, and the male genital bud is more prominent towards the front than the female genital bud.
  • Female genital bud: The direction of the female genital bud is downward, taking a position identical to the horizontal position. Doctors liken the shape of the female genital bud to the shape of swollen lips; Where the outer labia represent the shape of the lips, while the female clitoris is small and not clearly visible.

degree of intersection of the lines

In the event that the vision is not clear, the doctor can resort to a more accurate method to determine the gender of the fetus, which is to draw two straight lines through the ultrasound machine, and determine the shape of the angle resulting from the intersection of these two straights, where the first rectum is drawn in contact with the rectum, and the second rectum is in the flat surface, in contact with the ventral face of the genital bud, and when drawing these two rectums, it is required that the fetus take a position that allows obtaining a longitudinal image of it without any deviation; In order to reduce the possibility of error in determining the gender of the fetus.

  • In the event that the two lines are parallel and do not meet at any point, the fetus is most likely to be female, and the error rate is estimated between 0.9% and 3%.
  • In the event that the two straight lines intersect and draw an angle greater than thirty degrees, it is likely that the fetus is male, and the error rate is estimated at 0.2%.
