DETERMINING BABY SEX WITH ULTRASOUND (USG)
Ultrasonography has become very useful diagnostic tool for obstetrics since
late of 1050's. After several time, the technology of USG has greatly advanced
in USG half century lifespan. Now, the ultrasonography can help us to provide
realtime continuous pictures of the moving fetus. The high frequency sound waves
which emitted from a transducer that is located in contact with abdomen and
moved around like a flashlight all around the uterus will create the images
that we can see from the monitor. The monitor obtained the data from different
reflections and put back together as a picture. This can help the doctor viewing
malformations in the fetus, determining the size and growth, measurements to
assess gestinational age, and the movements of the fetus such as the heart beat.
Ultrasound scans are currently considered to be a safe, non-invasive, accurate
and cost-effective way to investigate the fetus. It has progressively become
an indispensable obstetric tool and can play an important role in the care of
every pregnant woman.
In order to be certain the sonographer (person performing the ultrasound) should
reassure herself that she actually sees the penis and scrotum in the case of
a boy and the labia in the case of a girl. The absence of the penis must not
be taken as sufficient evidence of the fetus being a girl. Most of the time
one should be able to tell the sex of the baby by about 20 weeks and very often
even at sixteen. On the other hand, as the correct visualization of any fetal
part depends of a host of factors such as fetal position, amount of liquor and
thickness of the abdominal wall, it may not be able to be certain about the
sex even at 28 weeks.
Just how accurate is the diagnosis of fetal gender by ultrasound? In general,
it should be very accurate (somewhere between 95 and a hundred percent), particularly
after about 20 weeks, or even sixteen. With modern equipment and techniques
it may be occasionally possible to determine gender as early as 11 or 12 weeks.
However, one must remember the person operating the ultrasound may not always
be able to get a good view of the private parts of the fetus for a variety of
reasons and therefore may not furnish you with an "accurate" answer.
You really need to press the sonographer as to the degree of certainty. (by
