When Can You Find Out the Gender of a Baby?
Understanding when you can find out the gender of your baby is a major milestone—often celebrated with a joyful gender reveal party. While a baby’s biological sex is determined at conception, clinical identification of fetal sex happens weeks later through prenatal diagnostic tests or non-invasive prenatal screening (NIPS).
Unlock the Science Behind Early Gender Discovery
Sex determination relies on whether the fetus carries an X or Y chromosome, which initiates sexual differentiation and the formation of genitalia and sex organs. Elevated testosterone levels lead to male traits, while oestrogen supports the development of female sex characteristics.
Thanks to advances in reproductive medicine, maternal-fetal medicine, and the early screening of genetic disorders, expectant parents can now identify the gender identity of an unborn baby as early as 7 weeks—well before standard fetal ultrasound anatomy scans at 18–22 weeks of pregnancy. This is made possible by analyzing fetal DNA from a simple blood sample using noninvasive prenatal testing.

What Are the Eligibility Tests?
To ensure accurate gender testing, a pregnant woman must meet specific criteria. These eligibility tests are designed to confirm that enough fetal DNA is circulating in the mother’s bloodstream for a reliable result.
The primary concern is gestational age, as fetal development and the concentration of cfDNA increase over time. Certain prenatal screening methods (such as NIPT screening) also assess for genetic abnormalities and chromosomal issues such as Down syndrome or sex chromosome abnormalities, further reinforcing the importance of testing at the appropriate time.
Two commonly used references are the Last Menstrual Period (LMP) and the Estimated Due Date (EDD):
-
1. Gender Test Eligibility Using the Last Menstrual Period
For many women, especially in their first pregnancy, the first step toward determining the sex of their baby begins by counting from the first day of their last menstrual period. This date helps estimate how many weeks have passed since conception, which in turn informs whether enough fetal cfDNA is present for reliable gender prediction.
Apps that track hormone fluctuations, fertility, and menstrual cycles can assist moms in identifying the most accurate LMP. These tools are particularly helpful in recognizing hormonal shifts that influence ovaries, embryos, and womb environment development. While cycle variability can introduce minor inaccuracies, LMP-based calculations remain a standard starting point for sex determination and non-invasive prenatal testing.
-
2. Gender Test Eligibility Using the Estimated Due Date
If a mom has had a clinical consultation, a healthcare provider may supply an Estimated Due Date (EDD) based on an early ultrasound scan or blood tests. This reverse calculation from the expected birth date allows professionals to gauge how far along the pregnancy has progressed in terms of fetal development.
This metric is crucial for at-home gender test kits or clinic-based evaluations, as testing too early—before the 7-week threshold—may yield inaccurate results. For instance, if insufficient Y chromosome material is found, the test might mistakenly indicate a baby girl, even if the fetus is a boy.
The EDD-based method also aids in timing other prenatal screening like amniocentesis, used to assess amniotic fluid for chromosome anomalies and birth defects. By aligning gender prediction tests with this medically validated timeline, mothers can improve accuracy and safeguard fetal wellbeing.

Why a blood sample?

How Does Early Gender Testing Work?
Early gender tests by EarlyReveal analyze fetal DNA found in the mother’s bloodstream. This non-invasive prenatal screening can identify the presence of the Y chromosome, indicating a baby boy. If only X chromosomes are found, it suggests the baby is female.
This technique represents a major advancement in reproductive technology. It minimizes risk to the fetus while offering critical information to support decisions related to parenthood, health planning and emotional preparation.
Here's how it works, step by step:
- Blood Sample Collection: A blood sample is taken from the pregnant person, usually after the 7th week of pregnancy.
- Isolation of Fetal DNA: Cell-free fetal DNA (cffDNA) circulating in the maternal blood is extracted and isolated in the lab.
- Chromosomal Analysis: Scientists analyze the DNA for the presence of the Y chromosome. If detected, the fetus is likely male, and if the Y chromosome is not found, the fetus is likely female.
- Optional Genetic Screening: The same sample may also be used to screen for certain genetic abnormalities or monitor sexual anatomy development.
*This form of sex selection is ethically regulated in many countries to prevent misuse for non-medical preferences—particularly in cases where gender bias could lead to the targeting of female or intersex babies.
Why 7 Weeks is Important to Determine the Baby’s Gender
The 7-week mark is pivotal in gestation because that is when the fetal fraction in maternal blood becomes sufficient for laboratory analysis. Around this point, the placenta—a critical structure in maternal-fetal medicine—begins shedding higher volumes of fetal DNA into circulation.
Before this time, pregnant women may not have a detectable level of cfDNA, increasing the likelihood of an incorrect gender prediction. For example, an early test might indicate a girl due to the absence of the Y chromosome, even if the fetus is male. The risk of such false negatives is why reputable labs emphasize waiting until at least the 7th week of pregnancy.
In cases of in vitro fertilization (IVF) or multiple pregnancies, additional considerations may apply, as fetuses can develop at slightly different rates. These scenarios may also involve early anatomy scans to assess for low birthweight, birth defects, or variations in sexual anatomy.
Ready to find out your baby’s gender with confidence?
Don’t leave it to chance or folklore—use science. Once you’ve reached 7 weeks of pregnancy, rely on precise, lab-tested methods rather than guesswork. Whether you're calculating from your last menstrual period or your estimated due date, EarlyReveal's trusted tools deliver accuracy when it matters most.
Alternative Gender Prediction Test
While medical gender determination is grounded in science, many expectant moms, wives, and daughters still explore traditional or cultural methods for fun. Though unscientific, these gender prediction techniques offer emotional bonding and anticipation during pregnancy.
-
Chinese Prediction Test
One of the most famous traditional methods is the Chinese gender predictor, based on a woman’s age at conception and the month the baby was conceived. This lunar-based matrix is said to predict whether you're having a girl or a boy.
Despite its popularity among expectant moms and families choosing baby names, there is no scientific evidence linking this model to actual fetal sex. Numerous studies confirm it performs no better than random chance, making it a charming—but unreliable—option for gender prediction.
-
Ring Gender Prediction Test
Another widely practiced tradition is the ring gender prediction test. In this method, a mom suspends a ring over her baby bump with a string. If it swings in circles, it supposedly predicts a girl; if it moves in a straight line, a boy.
This method relies on the ideomotor effect—small, unconscious muscle movements—and carries no biological correlation to sexual differentiation or sex organs. Nevertheless, it's a cherished practice among many families and often a highlight of the gender reveal celebration.

Why 7 weeks instead of 6?
The amount of cell-free fetal DNA increases over time during pregnancy, and most pregnant people won’t have enough cell-free fetal DNA in their blood at 5 or 6 weeks gestation to reliably predict their baby’s gender.
A smaller placenta at 5 or 6 weeks releases less fetal DNA into your bloodstream than a larger placenta later in pregnancy. This lower threshold can lead to “inconclusive” or inaccurate results.
