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. He said about 85 percent of couples want to find out the baby’s gender before delivery.

The feminist in me feels guilty about this, but I never wanted to wait that long. Genetic testing through CVS remains the most accurate way to determine fetal sex in the first trimester. The angle of the genital tubercle is one important clue. The ultrasound images below illustrate this. A male fetus is shown on the left, a female fetus on the right.

When I’ve been pregnant in the past, I’ve always had an intense need to know the gender of my baby. Being a control freak and habitual planner, I hated not knowing and I was counting down the days until the week morphology scan. Want to join the family? I looked to my husband as we were still in the process of debating whether or not we should find out my preference , or not his. So I found out I was expecting a boy when I was just under weeks pregnant.
I was told not to go out and buy things just yet because it’s not percent accurate. He said his success rate was around 80 percent, but it was an educated guess, and it turns out he was correct. By the time I had my second baby , and even my third baby , nothing had changed. I found out the sex of all three of my babies between 12 and 13 weeks along by way of an ultrasound, with three different technicians, all based on the nub theory.
Nub theory basically allows someone with a trained eye to determine the gender of an unborn baby through ultrasound. There have been many studies on the accuracy of sex determination via ultrasound during the first trimester and there are some pretty high accuracy rates too. The angle of the nub in relation to the spine is a predictor for the baby’s sex.

The limbs and the yolk sac, though obviously important, are not the primary means of measuring growth.
An average length of the embryo at 7 weeks is anywhere between 5mmmm. The average weight is less than 1 gram. Obviously, every pregnancy is unique and individual factors influence the size of the embryo at this early stage, and the embryo shows development week by week. The ideal time for a sonographer to assess the gestational age in the first trimester is between weeks of pregnancy. This is the period of time which provides the most accurate assessment.
Generally, ultrasounds which are performed in the first trimester are within days of being accurate in terms of assessing gestational age. This is because although every little embryo is unique, there are still defining characteristics of development which apply to all embryos at particular stages of early gestational development. As the embryo matures to a foetus, individual genetics and growth factors influence its growth.
This is why an early pregnancy dating scan, rather than one done in the later stages of pregnancy, is considered more accurate when assessing the expected date of delivery.

If you have not had any problems, then the Midwife will state that you are low risk and will be suitable for Midwifery-led care.

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.
