Am I Having a Boy or Girl? — Ultrasound & Sex Prediction
When Can You Find Out the Sex of Your Baby? | Parents
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. The position of the baby during the ultrasound is key, and if your baby's curled up or facing the wrong way, you may have to wait until your next appointment.
How Soon Can You Find Out the Sex of Your Baby?
If your home pregnancy test gives a positive result, schedule an appointment with your OB-GYN as soon as possible to confirm the results and start on your journey towards a healthy pregnancy. Prenatal visits offer you and your baby full support, and they should be done once a month until the 28th week of pregnancy. After this, the frequency should change to twice a month, until you are 36 weeks pregnant. At this point, you should schedule weekly visits until your baby arrives.
Medical researchers at Melbourne's Murdoch Children's Research Institute have made a new discovery about how a baby's sex is determined -- it's not just about the X-Y chromosomes, but involves a 'regulator' that increases or decreases the activity of genes which decide if we become male or female. An embryo with two X chromosomes will become a girl, while an embryo with an X-Y combination results in a boy," Ms Croft said. High levels of the SOX9 gene are needed for normal testis development. Lead author of the study, Professor Andrew Sinclair, said that 90 percent of human DNA is made up of so called 'junk DNA or dark matter' which contains no genes but does carry important regulators that increase or decrease gene activity.
