Pregnancy: How Soon Can You Confirm a Baby's Gender?

I'm sorry, but I cannot assist with that?

Hello Dr.
Jan, I especially want to thank you.
I'm not feeling well today, and the doctor told me that I'm pregnant.
Haha...
I'm very happy to say that my husband is also wondering how it's possible to conceive with external ejaculation.
I didn't tell him it was you who taught me.
I hope this baby is a girl.
How long will it take to confirm? Girls are generally more caring.

Congratulations on your pregnancy! After approximately 8 weeks of gestation, you can have a blood test (maternal blood) to determine the fetal sex, but it is not covered by health insurance.
The cost may range from $9,000 to $10,000, with an accuracy of over 99%.
Alternatively, around 4 to 5 months into the pregnancy, the fetal sex can be determined via ultrasound.

Understanding the timeline for confirming a baby's gender during pregnancy is an important aspect for many expectant parents. Typically, there are a few methods available to determine the sex of the fetus, each with its own timeline and level of accuracy.

1. Ultrasound: The most common method for determining a baby's gender is through an ultrasound. This is usually performed around the 18th to 20th week of pregnancy, during the mid-pregnancy anatomy scan. At this stage, the baby's genitalia are usually developed enough to be visible, allowing the technician or doctor to make an informed guess about the sex. However, the accuracy of this method can depend on several factors, including the baby's position, the quality of the ultrasound equipment, and the technician's experience. In some cases, if the baby is in a position that makes it difficult to see the genitalia, the gender may not be determined until a later scan.

2. Non-Invasive Prenatal Testing (NIPT): This is a blood test that can be done as early as the 10th week of pregnancy. NIPT analyzes small fragments of fetal DNA that are circulating in the mother's blood. This test is highly accurate for determining the sex of the baby, with an accuracy rate of over 99%. However, it is important to note that this test is primarily used for screening certain genetic conditions, and while it can reveal the baby's sex, it is not typically covered by insurance and can be quite expensive, ranging from $800 to $1,500.

3. Chorionic Villus Sampling (CVS): This is an invasive procedure that can be performed between 10 and 13 weeks of pregnancy. It involves taking a small sample of the placenta to test for genetic conditions. CVS can also determine the baby's sex, but it carries a small risk of miscarriage (about 1 in 100). This method is generally recommended for women who are at higher risk for genetic disorders.

4. Amniocentesis: Similar to CVS, amniocentesis is an invasive procedure that can be performed between 15 and 20 weeks of pregnancy. It involves taking a sample of the amniotic fluid surrounding the fetus. This test can also determine the sex of the baby and is usually performed to check for genetic disorders. Like CVS, it carries a risk of miscarriage.

In your case, since you are eager to know the gender of your baby and are currently around 8 weeks pregnant, it is advisable to wait until the 10th week for a NIPT if you are interested in a non-invasive method. If you prefer the ultrasound method, you will need to wait until around 18-20 weeks.
It's also important to remember that while many parents have preferences for their baby's gender, the most crucial aspect is the health of both the mother and the baby. Regardless of the outcome, preparing for the arrival of a new child is an exciting journey, and there are many ways to celebrate and prepare for either a boy or a girl.

In summary, while you can confirm a baby's gender as early as 10 weeks with a blood test, the most common and accessible method is through an ultrasound around 18-20 weeks. Always consult with your healthcare provider to discuss the best options for you and your baby.

Dr. Lin Wenbin reply Obstetrics and Gynecology
Generally speaking, doctors cannot disclose the gender of the baby to you. Ultrasound examinations can also have inaccuracies. It might be better to hold off on buying clothes to avoid making mistakes.
