Everyone is interested prior to birth what the baby's sex will be. Below I explain the many different ways high tech, low tech, and no tech to predict a baby's sex.to 

The High Tech Way To Predict The Baby Gender 

Noninvasive prenatal test (NIPT)

The NIPT or noninvasive prenatal testing is a blood test of the mother and it can be done throughout pregnancy starting from as early as the 9th month of the pregnancy. The test checks for the presence or absence of the Y-chromosome. If the Y chromosome is present then the baby's sex is a boy, otherwise it's a girl. However, the main reason to do this test is to check the baby's risk of chromosomal abnormalities including trisomy 21 (Down syndrome), trisomy 18 (Edwards syndrome) and trisomy 13 (Patau syndrome). The NIPT is a screening test, which means that if an abnormality  is found, it must be confirmed with other testrs such as CVS or amniocentesis. 

Chorionic Villus Sampling (CVS)

Chorionic villus sampling (CVS) is an invasive test done around 11-13 weeks of the pregnancy. A needle is inserted either through the abdomen or vaginally through the vagina with the help of ultrasound and a tiny portion of the placenta is removed and examined. The CVS reveals the baby's gender as well as chromosomal anomalies. 

Amniocentesis (Amnio)

Amniocentesis like CVS is an invasive test. The amniocentesis is usually done around 16-18 weeks of the pregnancy with a needle inserted  through the abdomen with ultrasound guidance. A small amount of amniotic fluid, about 10 cc or less than 5-10% is remopved and sent to the laboratory.  The amniocentesis reveals the baby's gender as well as chromosomal anomalies.  


An ulktrasound is a noninvasive test usually done around 18-20 weeks of the pregnancy As part of the anatomy screen, the technician and doc tor will check between the baby's legs to confirm it there are labia (girl) or a penis/scrotum (boy). The ulttasound is not 100% accurate and mistakes have been known to have been made.

NIPT, CVS, amniocentesis are very reliable methods to determine the baby's sex. There are other methods, most of which are less to unreliable. 

Baby-Gender Prediction Kits

There are different kinds of products sold directly to the customer promising tgo reveal the baby's sex.

Some kits sold on Amazon tests your urine for as low as $14.95. It says that it's not really accurate as the technology to reliably determine the baby's sex from the mother's urine does not exist yet.

Another test sold online is a blood test of the mother at home. It claims to be the same as the NIPT test. The test costs about $80 and can be done after 9 weeks of the pregnancy and claims to be 99% accurate.
