When is the gender of the fetus determined?

Before exploring this question, we first need to understand the determinants of human gender. Human gender is determined by chromosomes. Everyone has 23 pairs of chromosomes, one of which is a sex chromosome. Women have two X chromosomes (XX), while men have one X chromosome and one Y chromosome (XY). Therefore, the determinant of gender is mainly the sex chromosomes carried by the father\’s sperm. CCTV recommends over 500 excellent documentaries with high scores. Children will become self-disciplined and addicted after watching them. So, when is the gender of the fetus formed? During fertilization, the father\’s sperm and the mother\’s egg combine to form a fertilized egg. The combination of sex chromosomes in the fertilized egg determines the gender of the fetus. If the fertilized egg contains an XX chromosome combination, the fetus will be female; if it contains an XY chromosome combination, the fetus will be male. This process is usually completed within a few hours after fertilization, which means that the gender of the fetus is determined in the earliest stages of pregnancy. However, although sex is determined at fertilization, the development and expression of fetal sex is a gradual process. In the early stages of pregnancy, the fetus\’s reproductive organs are not fully developed, and the gender cannot be accurately determined through medical means such as ultrasound. Usually, the reproductive organs do not begin to develop until after 12 weeks of pregnancy. At this time, gender identification can be carried out through medical means. However, even in late pregnancy, gender identification may be difficult due to certain factors (such as body position, amniotic fluid, etc.). It is worth noting that although the gender is determined at fertilization, under certain special circumstances, such as chromosomal abnormalities, genetic mutations, etc., the gender of the fetus may change. But this condition is very rare and requires further research and diagnosis by medical experts. In general, the sex of the fetus is determined by the sex chromosomes carried by the father\’s sperm during fertilization. Although the gender cannot be accurately determined in the early stages of pregnancy, after 12 weeks of pregnancy, gender identification can be carried out through medical means. However, in some special circumstances, the gender of the fetus may change. I hope this information can help everyone better understand the formation and development of fetal gender.
