When & How Can I Find Out My Baby's Sex (Gender)?

Gone are the days of waiting until delivery to discover your baby’s gender. With advancements in technology, you can now find out the sex of your baby as early as 10 weeks into your pregnancy. By undergoing a CVS test between 10 to 13 weeks, you can receive results within a day or two. Alternatively, an NIPT test at 10 weeks can provide gender information a week or two later. For those who prefer to wait a bit longer, an amniocentesis performed between 15 to 20 weeks can deliver results within a couple of days. These modern options grant expecting parents the opportunity to learn their baby’s gender earlier than ever before.

How can I determine the sex of my baby and at what point?

The curiosity of expectant mothers about the gender of their baby has given rise to various myths and old wives’ tales. Some common beliefs suggest that the way a woman carries the baby, the baby’s heart rate, or the swing of a ring over the belly can determine the baby’s sex. While a few of these tales may hold some truth, such as women carrying girls experiencing more severe nausea, the majority lack scientific evidence. Even mothers who strongly believe they can intuitively know the baby’s gender are often incorrect about half the time.

What are the reliable options and timelines available for determining the sex of your baby while you are pregnant?

NIPT

Noninvasive prenatal testing (NIPT) offers a way to determine your baby’s sex as early as 10 weeks into pregnancy. This blood test not only detects chromosomal conditions like Down syndrome but also analyzes the presence of male sex chromosome fragments, revealing whether you’re expecting a boy or a girl. It is accessible to all pregnant women, providing results within a few weeks. If you’re keen on knowing the gender of your baby, discuss the test with your healthcare provider to ensure it is offered to you.

IVF with sex selection

Preimplantation genetic testing, conducted during in vitro fertilization (IVF), allows for accurate determination of the sex of embryos with nearly 100-percent accuracy. This testing not only identifies genetic or chromosomal abnormalities but also enables the selection of the baby’s gender. However, when embryos of both sexes are implanted into the uterus, it becomes uncertain which one(s) will successfully implant, leaving the specific outcome unknown.

CVS

Chorionic villus sampling (CVS) is a genetic test performed between 10 and 13 weeks of pregnancy to detect genetic disorders or chromosomal abnormalities in the baby. While its primary purpose is not determining the baby’s sex, CVS can inadvertently reveal this information. The procedure involves extracting cells from the placenta and analyzing them in a lab, which provides genetic insights including the baby’s gender. However, since CVS is an invasive procedure associated with a slight risk of miscarriage, it is typically recommended for women with an increased risk of genetic or chromosomal problems rather than for those without such indications.

Amniocentesis

Amniocentesis is a genetic test similar to CVS that can identify birth defects and chromosomal abnormalities like Down syndrome. Typically performed between 15 and 20 weeks of pregnancy, although it can be done later, amniocentesis can provide the baby’s gender within a few days. It is available to all expecting mothers but is generally recommended for those at a higher risk of genetic or chromosomal issues. However, since amniocentesis is an invasive procedure carrying a small risk of miscarriage, it is typically reserved for women with specific indications rather than being performed routinely. Remember to inform your doctor if you prefer not to know the baby’s sex.

Ultrasound

The mid-pregnancy ultrasound, typically performed between 18 and 22 weeks, allows many expectant mothers to discover their baby’s sex if they opt to know. By utilizing sound waves to generate images of the baby, the ultrasound technician can determine the baby’s gender by examining their genitals. Although male and female genitalia start developing as early as 6 weeks, it can be challenging to differentiate them on ultrasound until around 14 weeks. While some studies suggest the possibility of earlier gender determination, it is typically more reliably determined during the mid-trimester ultrasound. However, even at this stage, certain factors like the baby’s position can hinder a clear view, necessitating the possibility of a later ultrasound for obtaining a conclusive result.

Can gender predictor tests be trusted for accurate results?

Gender predictor tests, including the widely known Chinese Gender Predictor tool, are primarily meant for entertainment purposes and have an accuracy rate comparable to random guessing. At-home gender kits available online claim to predict the baby’s sex using blood or urine samples, but there is no scientific evidence supporting their effectiveness. Brands like SneakPeek and Juno Birch assert over 99 percent accuracy with blood-based tests as early as 6 weeks, but these claims lack independent research validation. Urine-based kits, such as GENDERmaker, which test as early as 6 weeks, generally do not make accuracy claims due to the absence of pertinent information in urine. It’s important to note that urine does not contain DNA or sex hormones necessary for predicting the baby’s gender. While these tests can be enjoyed for amusement, consulting with a healthcare provider remains the best approach for reliable information on determining the baby’s sex based on individual circumstances.
