When it comes to predicting the gender of an unborn baby, many old wives tales emerge. According to some, if you carry your baby bump low that means you're having a baby boy, or if you happen to be craving sweets, you're apparently expecting a baby girl. The nub theory claims to be a lot more accurate than some of those old wives tales — and says you can even tell the sex of your baby just by looking at your 12 week ultrasound picture.
Throughout history, many parents didn't want to wait until the actual birth to find out. They'd wave crystals over the mother or consult the stars. Now, of course, there are much more accurate ways to determine gender before a baby is born. If you're at least 12 weeks pregnant, your doctor can probably tell you the sex of your baby with a high degree of confidence.
Boy or girl? Here's everything you need to know about when you can find out the gender of your baby through ultrasound. This is one of the most common questions doctors get from parents-to-be.
Sometimes, knowing the sex of the unborn baby is desired for medical purposes. For example, when a specific genetic disease runs in the family and is gender specific. That said, most of the time, people wish to know out of pure curiosity.
The tests have been available to consumers in drugstore chains and online for a few years, but their use has been limited, partly because their accuracy was unclear. One company, which guaranteed European doctors now routinely use the tests to help expectant parents whose offspring are at risk for rare gender-linked disorders determine whether they need invasive and costly genetic testing.
Ultrasounds have a variety of purposes during pregnancy, but the use that often receives the most attention is its ability to reveal the sex of the baby. Some parents-to-be can't wait to find out whether they're having a boy or a girl, while others choose to put off knowing the sex until birth. Either way, a sonogram — the grainy, black-and-white image that results from an ultrasound scan — will be baby's earliest picture and a couple's first chance to see the developing fetus. Ultrasound uses high-frequency sound waves to produce an image on a screen of the baby in the mother's uterus.
So how and when can you find out the sex of the baby? Keep reading. The test analyzes a sample of your blood, looking at tiny fragments of fetal DNA that are released from the placenta into your bloodstream.
Although the formation of the vulva or penis of a baby starts occurring by the 6th week of pregnancy, girl and boy babies look quite similar during a first-trimester ultrasound and till about 14th week of pregnancy. By the 18th week, your doctor may be able to determine the sex of your baby if they are lying in a position that makes their genitals visible. You may also find out the gender of your baby by having non-invasive prenatal testing NIPT that is usually done at the 10th week of pregnancy.
