For most of the tests listed, finding out the sex is a secondary benefit while the test looks for other information. IVF assists with fertility by combining a mature egg with sperm outside of the body. This creates an embryo , which is then implanted in the womb. If you choose, you can have the sex of different embryos identified, and then only transfer the embryos of your desired sex. Sex selection in conjunction with IVF is about 99 percent accurate.
You can have this test starting at 10 weeks of pregnancy. It only screens for the possibility. If your baby has abnormal results, your doctor may order further tests to diagnose Down syndrome and other chromosome disorders.
This test can also accurately determine the sex of your baby. Chronic villus sampling CVS is one genetic test used to identify Down syndrome. This test removes a sample of chorionic villus, which is a type of tissue found in the placenta.
It reveals genetic information about your baby. You can have this test as early as your 10th or 12th week of pregnancy. And because it has gene information about your baby, it can also reveal the sex of your baby. This is an accurate test for finding out the sex of the baby, but it does involve some risks. Amniocentesis is a test that helps diagnose detect developmental issues in a fetus.
Your doctor collects a small amount of amniotic fluid, which contains cells that indicate abnormalities. The cells are tested for Down syndrome, spina bifida , and other genetic conditions. You can have this test around 15 to 18 weeks of pregnancy, and it takes about 30 minutes.

Early development Your baby's sex is set at conception by the sex chromosome received from the sperm X for girl or Y for boy , but it takes a while for the actual body parts to develop. Boy parts A boy's testes, the glands that make and store sperm, are recognizable in his abdomen at 9 weeks.
Girl parts A girl's uterus and ovaries are evident around 12 weeks. Kidneys, bladder, and urethra As the internal sex organs are developing in the abdomen, your baby's kidneys are forming nearby. Peeing practice The kidneys start making urine by 14 weeks of pregnancy. What you can do during pregnancy If you want to know your baby's sex before birth, there are a few ways to find out.
