how many weeks do you have to be to find out the sex of baby?

Answer 1

there are 3 different ways to find out.

---------------------------------------------------

Chorionic Villus Sampling (CVS)--

This diagnostic test is usually performed between 8 and 11 weeks gestation, sometimes as late as 13 weeks. This is generally a test for people who have a high risk of genetic abnormalities. Test results are available within 7 to 14 days. Miscarriage rate from CVS is about 4%, recent studies indicate that if the CVS is done before 10 weeks gestation there is an added risk (.5% to 1.7%) of limb deformity, and about 3% CVS is associated with serious decline in amniotic fluid protection. There is a greater incidence of false positives because of the differences between the cellular genetic material of the choirionic villi and the fetus. There is a small chance that the sex they determine is wrong as well.

Amniocentisis--

This diagnostic test is performed as early as 9 weeks and for diagnostic purposes, 18 weeks gestation. There is a risk of 1-1.5% miscarriage and 1% chance of other pregnancy complications (infection, premature labor, injury to the fetus, cord, or placenta, rupture of membranes, etc.). The tests take about 2-4 weeks to run. There is a small chance that the sex they tell you is incorrect.

Ultrasound--

While ultrasound can be performed at any stage of pregnancy for the purpose of finding out the sex it is best done between 18 and 26 weeks. Most care providers will not give an ultrasound for the specific purpose of finding out the sex, and the American College of OB/GYNs has issued a statement against routine ultrasound exposure during pregnancy. However, most physicians do not heed this warning. Adequate studies on ultrasound safety have not been done, but we do know that ultrasound exposure can change the way the cell reproduces and moves. There have also been studies indicating that ultrasound heats up the cells. This method is the most frequent for finding out the sex of a baby, however, it is the least accurate. Accuracy depends on several factors: baby's cooperation, gestational age, technician's ability, etc.

Answer 2

It depends. If you have a history of genetic abnormalities in your family, you can get a CVS test, and that can be used to determine sex between 7-9 weeks. If you're over 35 you usually get an amniocentesis around 13-17 weeks. Both procedures are risky to the baby, so if you have little chance of genetic problems, you might be able to tell with an ultrasound between 18-24 weeks, but the genetalia are visible as early as 16 weeks.

The two chromosomal tests are accurate to 99.9%, assuming the lab doesn't mix up the samples. The ultrasound is only 70-80%, and depends heavily on the position of the baby, the experience of the doctor or technician performing the procedure, and the confidence level of the doc or tech.

Answer 3

I would say at least 22 weeks. The doctors told me I was having a girl and that was at 20 weeks but guess what I had a boy.

Answer 4

It is possible at 16 wks, but the genitals might not be very visible by then. The best time is between 18 and 20 wks.

Answer 5

usually between 18 and 20 weeks

Answer 6

They say to do an ultra sound after 20 weeks, but they can also be wrong at that point. To be absolutely sure I would do another one after 28 weeks..

Answer 7

reckoning on how "shy" your toddler is would be certain in case you will discover out the intercourse... All of his/her exterior genitals are nicely formed via 26 weeks- so as long as their legs are not crossed or they don't have their palms between their legs, you need to be waiting to be certain! reliable luck! =)

Answer 8

My friend Holly was five months pregnant.

Answer 9

twenty some weeks, well whenever ur five or six months preg
