Week 4-5
The development of your baby’s sex organs begins just four weeks after conception. During this time, the fertilized egg divides into two parts, one of which will become the placenta, while the other develops into the embryo. The embryo at this stage is called a blastocyst and has not yet developed any organs or body parts. The sex of the baby is determined at this stage by the chromosomes it inherits from its parents. If the baby inherits two X chromosomes, it will be female, while if it inherits an X and a Y chromosome, it will be male.
Week 6-7
During the sixth week of pregnancy, the baby’s sexual organs begin to form. At this stage, the genital tubercle, which will eventually become either a penis or clitoris, starts to develop. The sex of the baby can be determined by looking at the angle of the genital tubercle. If it is pointing upwards, the baby is male, while if it is pointing downwards, the baby is female. By week seven, the ovaries or testes begin to form.
Week 8-12
By week eight, the sex organs are fully formed, and the baby’s sex is clear. However, the external genitalia may not be visible on an ultrasound until week 12. During this time, the baby’s genitals are still developing and will continue to do so throughout the pregnancy. By week 12, the baby’s reproductive system is functional, and the ovaries or testes begin to produce the hormones necessary for sexual development.

During the second trimester, the baby’s external genitalia become more distinct. By week 13, the penis or clitoris is visible on an ultrasound. By week 16, the baby’s genitals are fully formed, and the baby’s sex can be determined with more accuracy. The baby’s testes or ovaries continue to produce hormones necessary for sexual development.
Week 20-24
During the fifth month of pregnancy, the baby’s reproductive system is fully developed. The baby’s testes or ovaries are producing sex hormones, and the baby’s external genitalia are fully formed. At this stage, a detailed ultrasound can provide a clear picture of the baby’s sex organs.
Conclusion
As we can see, the development of the baby’s sex organs begins early in pregnancy and continues throughout the pregnancy. By week 20, the baby’s sex organs are fully formed, and the baby’s sex can be determined with accuracy. It is important to note that the development of the baby’s sexual organs is a natural process and may vary from baby to baby. Understanding the timeline of your baby’s sexual development can help you prepare for the arrival of your little one.
In summary, the development of a baby’s sex organs starts at week four and five after conception. By the sixth and seventh week, the genital tubercle starts to develop, and by week eight, the sex organs are fully formed. The external genitalia may not be visible on an ultrasound until week 12. During the second trimester, the baby’s external genitalia become more distinct, and by week 20, the baby’s sex organs are fully formed. So, you can determine the sex of your baby after week 20 with more accuracy.
