As a new mom, you may wonder what to expect when it comes to your baby’s genital development. Knowing what is normal can help ease any concerns you might have. During pregnancy, your baby’s genitalia begin to form, and by week 12, your baby’s sex can be determined. From there, your baby’s genitals continue to develop throughout the pregnancy and after birth.

Weeks 6-9

During these early weeks, your baby’s genitalia start to form. The genital tubercle will begin to develop, which can later become either a penis or clitoris, depending on your baby’s sex. The external genitalia will start to differentiate, with the labioscrotal swelling beginning to develop.

Weeks 10-13

By week 12, your baby’s sex can typically be determined through an ultrasound. Your baby’s external genitalia will continue to grow and develop, with the labioscrotal swelling either forming into labia or a scrotum. The genital tubercle will also either grow into a penis or clitoris.

Weeks 14-16

During these weeks, your baby’s external genitalia will become more apparent. The testes or ovaries will also begin to descend, which is important for future fertility.

Weeks 17-20

Your baby’s external genitalia will be fully formed by this point. The testes will have descended into the scrotum (in males) or the ovaries will have formed (in females). The clitoris will be fully formed, and the labia will have either fused together or partially fused.

Weeks 21-24

Your baby’s genitalia will not undergo any significant changes during this time, but the testes will continue to mature in males.

Weeks 25-28

The testes will continue to mature in males and will soon begin to produce testosterone. This is important for the development of male secondary sex characteristics.

Weeks 29-32

By this point, the testes should be fully matured in males. In females, the ovaries will begin to produce estrogen. The clitoris may become more prominent due to increased blood flow.

Weeks 33-36

The genitalia will not undergo any significant changes during these weeks, but the testes will continue to produce testosterone in males.

Weeks 37-40

By the time your baby is born, their genitalia should be fully formed and appear typical for their sex. However, it is important to note that some babies may be born with ambiguous genitalia, which can be a sign of a genetic disorder. If this is the case, your doctor will work with you to determine the best course of action.

In conclusion, understanding your baby’s genital development week by week can help alleviate any concerns you may have. Remember that every baby is unique, and while there is a typical progression, there may be variations. If you have any concerns or questions, always consult your healthcare provider.
