Obstetric ultrasonography , or prenatal ultrasound , is the use of medical ultrasonography in pregnancy , in which sound waves are used to create real-time visual images of the developing embryo or fetus in the uterus womb. The procedure is a standard part of prenatal care in many countries, as it can provide a variety of information about the health of the mother, the timing and progress of the pregnancy, and the health and development of the embryo or fetus. The International Society of Ultrasound in Obstetrics and Gynecology ISUOG recommends that pregnant women have routine obstetric ultrasounds between 18 weeks’ and 22 weeks’ gestational age the anatomy scan in order to confirm pregnancy dating, to measure the fetus so that growth abnormalities can be recognized quickly later in pregnancy, and to assess for congenital malformations and multiple pregnancies twins, etc. Performing an ultrasound at this early stage of pregnancy can more accurately confirm the timing of the pregnancy, and can also assess for multiple fetuses and major congenital abnormalities at an earlier stage.

Will an ultrasound scan show the sex of my baby?
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. The scans are typically done twice during pregnancy, but the one done between 18 and 22 weeks is when the sonographer ultrasound technician might identify the gender of the baby, if parents want to know. Expectant parents who want their child’s sex to remain a secret until birth are in the minority, said Dr.

The sex of a baby is genetically determined at conception, but during the early development of embryos, they all look the same. All embryos have a genital nub or protuberance. If you are having a boy, the bud grows and develops into a penis and scrotum. In a girl the genital nub will become the clitoris and labia.

Have you ever been one of those people who think “oh, that could never happen to me? But, to my surprise, I have become the person that things happen to. More specifically, I’m the person whose baby’s gender was incorrectly diagnosed! My husband and I learned last week that, contrary to our belief and the information provided to us over the past five months, our sweet baby number two is not, actually, a boy.
Here’s the quick version of our story: At about 13 weeks pregnant, I had my end-of-the-first-trimester ultrasound. My doctor’s office, with the caveat that it was pretty early, said they were about 75 percent sure it was a boy. Fast forward two weeks, when my hubs and I for whom patience is not a virtue got an elective ultrasound with an ultrasound technician’s office and he declared that it was percent a boy.
He also called my son’s gender at the same time frame, so we trusted him and his opinion. At 20 weeks, I had another ultrasound with my doctor’s office. Apparently my little bean had legs crossed and pulled back, so there was no gender confirmation done that day. But we showed the technician the 15 week photos and she, like us, was pretty sure at what we were looking at and said, for sure that’s a boy! Now, here we are, 13 weeks later.

It is also unlikely you will find out the sex with an NHS scan at 16 weeks, as generally, the only scans you are given in the first and second trimester is the week dating scan, where telling the sex is not possible, and the 20 week anomaly scan. Some private scanning places have deals which often include 4D peeks, teddy bears and photos, and even a little video of your bub moving around.
And, if you want to make the sex a surprise, you can always ask the sonographer to keep it private, and write it down in an envelope for you so that you can have a reveal later on, with both private and NHS scans. Though most places will not perform a gender scan on you until 16 weeks, sometimes you can see what you are having sooner. If the baby is in the correct position — with their legs open with a clear view from underneath — it may be obvious to the sonographer as early as 14 weeks, as by then the differentiation of male and female sex characteristics are complete.

Objectives : The purpose of this study was to determine the accuracy of sonographer predictions of fetal gender during routine ultrasounds. Primarily, the study sought to investigate the accuracy of predictions made in the first trimester, as requests from parents wanting to know the gender of their fetus at this early scan are becoming increasingly common. Second and third trimester fetuses were included in the study to confirm the accuracy of later predictions.
In addition, the mother’s decision to know the gender was recorded to determine the prevalence of women wanting prenatal predictions. Methods : A prospective, cross sectional study was conducted in a specialist private obstetric practice in the Illawarra, NSW. A total of fetuses across three trimesters were examined collectively by seven sonographers.
Fetal gender was predicted using the sagittal plane only in the first trimester and either the sagittal or transverse plane in later trimesters. Phenotypic gender confirmation was obtained from hospital records or direct telephone contact with women postnatally. Male fetuses under 13 weeks were more likely to have gender incorrectly or unable to be assigned.
After 13 weeks, success rates for correctly predicting males exceeded that of female fetuses.
