Is there any way to tell whether you are pregnant with a boy or a girl? How many months into the pregnancy can you tell whether it is a boy or a girl?

How many months of pregnancy can you tell whether a man or a woman is pregnant?

When the fetus is 9 weeks and 12 weeks old (3rd month), the gender can be identified based on the reproductive organs. As the baby gets bigger, the external genitalia develop faster, so you can naturally see everything more clearly and accurately. Generally, the sex of the fetus can be determined by B-ultrasound around April, but it depends on the position of the fetus. If the fetal position is beautiful, it is accurate, but don't be too confident in the judgment. The development of the fetus's genitals is different for boys and girls, and the time is also different. Boys usually conceive earlier, with the start of sex hormone secretion from the 6th week of pregnancy, the testicles beginning to grow from the 9th week, and the reproductive organs beginning to form after 18 weeks. Women begin to start secreting sex hormones from 8-10 weeks, and the vagina, uterus, and fallopian tubes begin to form from 11-12 weeks. The reproductive organs of the fetus have developed by the 12th week, and the sex of the fetus can be determined from the reproductive organs by the 16th week. The reproductive organs of a full-term fetus are fully developed. It is generally more accurate in May and June.

The most intuitive and accurate way to identify the sex of the fetus is through B-ultrasound examination. Generally, the gender of the fetus can be known by B-ultrasound examination around the fourth month of pregnancy. At 12 weeks of pregnancy, the fetal reproductive organs have already developed. At 16 weeks, the sex of the fetus can be determined from the reproductive organs. During the examination, the fetal position should be considered. When the fetal position is better, the judgment is more accurate. Therefore, the sex of the fetus determined by B-ultrasound is affected by the doctor's experience and the fetal position. Prospective parents should note that although B-ultrasound can clearly show every organ and position of the fetus, including sexual organs, the current laws and regulations in my country stipulate that it is a violation of discipline to privately conduct fetal gender identification and assessment through B-ultrasound. In addition to traditional B-ultrasound examinations to identify the gender of the fetus, amniocentesis and chorionic villus sampling can also be used to determine the gender of the fetus. However, pregnant mothers should remember that amniocentesis is an invasive test with a 1% risk of miscarriage. Pregnant mothers who do not need to undergo this test should not take this risk, and should not use this method to check the gender of the fetus.

How to tell the gender of a woman during pregnancy

DNA blood test: When the pregnant woman has been confirmed to be 8 weeks pregnant by B-ultrasound and the fetus is normal, the sex of the fetus can be determined with an accuracy of 98%. More importantly, this method will not cause any impact on the pregnant woman and the fetus.

Villus puncture biopsy: Pregnant women can undergo villus puncture biopsy when they are 10-12 weeks pregnant, but this villus puncture biopsy is usually used to identify the gender of the fetus when there may be serious gender-related problems in the baby.

Amniocentesis: Amniocentesis is a test that draws a sample from the amniotic fluid of a pregnant woman, usually around 18-20 weeks of pregnancy, and then analyzes the baby's cells. Generally speaking, this method is only done when the possibility of the baby being deformed is increased, and it is usually only used to determine the gender of the fetus when the baby is at risk of serious genetic problems.

Ultrasound scanner: Ultrasound is a sound wave frequency that has no adverse effects on the fetus, but this method is more accurate only when the baby is between 3 and 4 months old. However, when using ultrasound to diagnose the sex of a fetus, the accuracy of confirming a boy is over 95%, while the reliability of confirming a girl is only about 85%.
