However, amniocentesis and chorionic villus sampling CVS can produce a fairly accurate result because they involve looking at the sex chromosomes. Noninvasive prenatal testing NIPT uses bloodwork to assess the risk of a several genetic disorders. NIPT can also identify the sex because the test scans for the presence of a Y chromosome, the chromosome that generally results in a male baby. Typically, doctors usually perform the test toward the middle or end of the first trimester, at about 10 weeks or later.
Healthcare providers usually schedule it within weeks 18—22 of the pregnancy. At this time, the developing baby is usually large enough for the healthcare professional to see the genitals. A skilled technician can often identify the sex based on their appearance. A healthcare provider cannot always detect the sex with an ultrasound because the developing baby may be too small.
When this happens, a healthcare professional might recommend coming back for another scan in a few weeks. If an anatomy scan shows potential problems with the fetus, a doctor may recommend additional, more invasive, testing.
According to Planned Parenthood , amniocentesis and CVS both involve taking samples of genetic material. Although these tests can accurately predict the sex of the developing baby, doctors carry out these tests to identify chromosomal abnormalities, such as Down syndrome. They do not routinely carry out these tests to determine sex. Both tests can cause serious complications, so a person should not choose either method unless there is a medical reason to do so.
Some prenatal sex tests can determine the sex of a developing baby by identifying the external features while others detect the chromosomes. NIPT blood testing can detect chromosomes but may not predict the development of the genitals. For example, a newborn with male-typical XY chromosomes might have an unusually small penis that resembles a clitoris.
However, NIPT does not detect all chromosome abnormalities, so it may not identify that a fetus has an unusual chromosome pattern. More testing will be required if your NIPT comes up with positive results. If absent, your baby will be a girl.
In this test, amniotic fluid is extracted to check for fetal abnormalities such as cystic fibrosis or spina bifida. Chorionic villus sampling CVS is an invasive prenatal test in which your doctor pulls a sample of chorionic villi from the placenta and examines them for chromosomal disorders, such as sickle cell anemia or Tay-Sachs disease. Doctors can perform CVS as early as week ten of your pregnancy. Like amniocentesis, CVS is only done if your prenatal screenings come back positive.
Therefore, it should not be done for gender determination alone. If you decide to go through in vitro fertilization IVF , you can find out the gender of your baby at the beginning of your IVF procedure s.
NIPT has a high accuracy for assessing fetal Trisomy risk. Accuracy for detecting other sex chromosome anomalies varies by condition. The Harmony testing includes taking blood from the mother and also carrying out a scan too and this can be done from 10 weeks onwards.
The Panorama testing can be conducted from 9 weeks onwards. Nipt is the earliest option available to finding out the gender of your baby as this can be done from 9 weeks on wards. NIPT analyzes blood drawn from the pregnant person, and it doesn't pose any risk to the fetus. By analyzing the cfDNA, the NIPT screens for some chromosomal disorders, and it can see how many copies of the X and Y chromosome the fetus has, thus establishing the sex of the baby.
Recommended for some pregnant people, amniocentesis and chorionic villus sampling CVS screen for genetic abnormalities in a pregnancy, according to the Centers for Disease Control and Prevention CDC.
As a byproduct of performing the tests, parents-to-be can learn the sex of their baby in a more reliable way. With amniocentesis, a needle is inserted through the abdomen into the uterus to sample amniotic fluid. It carries a small risk of miscarriage, but it's generally very safe. The procedure is usually done between 15 and 20 weeks' gestation. On the other hand, CVS involves taking a sample of tissue from the placenta for screening, and it also looks at fetal chromosomes.
Parents-to-be can learn their baby's sex during routine ultrasounds —but keep in mind that it's not the primary medical value of these tests. For example, the anatomy scan, which usually takes place between 18 and 22 weeks, confirms the proper growth of the fetus.
The technician takes a variety of measurements including crown-to-rump length , estimates fetal weight, examines the placenta, and checks internal organs and sex organs, according to Johns Hopkins Medicine.
Pregnant people can learn the sex of the baby as part of the anatomy scan, if they wish. Often an ultrasound technician or doctor will ask if the patient would like to learn the sex of the baby, and they may decline if they prefer to be surprised.
