Many pregnant women know their baby's gender (if they choose to know) during their mid-pregnancy ultrasound, usually performed between 16 and 20 weeks. However, if the technician could not get a clear view of the baby's genitals, it may not be possible to say with certainty.
Although the baby's penis or vulva began forming as early as 6 weeks, boys and girls baby looks very similar to the ultrasound until about 14 weeks, and they will be difficult to distinguish them for a few weeks afterwards. By 18 weeks, an ultrasound technician will most likely be able to identify the sex - if the baby is in a position that allows the genitals to be seen. If not, you may be able to tell if you have another ultrasound later in your pregnancy.
You can find out the sex of your baby if you have, a blood test that can detect Down syndrome and other chromosomal some conditions ranging from 10 weeks of pregnancy. It also looks for pieces of the male sex chromosome in the blood, which can be used to determine whether you are carrying a boy or a girl. This test is intended for women at higher risk of having a baby with chromosomal abnormalities but often available for lower-risk women as well. Discuss with your provider whether the test is appropriate for you
Note :. Some of what you can do at home claims to provide accurate results as early as 9 weeks. But with no independent research to support their claims, you might be better off relying on a standardized test to determine the sex of your baby. More on this below.
Another woman know the sex of their babies from genetic tests like or. This test is usually performed to determine whether the baby has a genetic disorder or chromosomal abnormalities, such as Down syndrome. CVS is usually performed between 10 and 13 weeks, and amniocentesis between 16 and 20 weeks. Women who are not at increased risk for genetic and chromosomal problems do not usually have CVS or amnio, in part because the test is invasive and carries a small risk of miscarriage.
If you have the time (IVF), embryo you are tested for genetic or chromosomal abnormalities and sex. preimplantation genetic testing nearly 100 percent accurate in determining the sex of the embryo.
There is no shortage of methods to predict the sex of the baby at home, but this method is less scientific evidence. For example, it is not recognized by professional medical organizations (including the American College of Obstetricians and Gynecologists) as a reliable predictor. Most obviously just for fun and only offers a 50/50 chance of being accurate -. Just like guessing
At-home kits sex (provided mostly online) blood or urine test to predict the sex of your baby, but there is no scientific evidence that these tests really work.
SneakPeek, for example, test blood samples and claims to be 99 percent accurate as early as 9 weeks, but there is no independent studies support this claim. IntelliGender is a kit at home urine test to predict the sex of your baby, but the company did not claim a certain degree of accuracy. It is also recommended to make a decision based on the results of the test, stressed that it was really just for fun.
