You can usually find out the sex of a baby any time from about 8–10 weeks of pregnancy onward, depending on the test or method used.

Quick scoop

• Earliest (blood/DNA tests):
  • Some private or at‑home gender blood tests claim to detect sex from around 6 weeks, using fetal DNA in the mother’s blood, though reliability and regulation can vary.

* Medical non‑invasive prenatal testing (NIPT) offered by a clinician can usually tell sex starting around 10 weeks and is often highly accurate because it looks at fetal chromosomes.

• Standard ultrasound at the doctor’s office:
  • External genitals start forming early but usually are not clearly distinguishable on ultrasound until around 14 weeks or later.

* Many providers aim for the mid‑pregnancy anatomy scan at about 18–22 weeks, when the view is better and accuracy for sex is around 95–98%.

• More invasive tests (done for medical reasons):
  • Chorionic villus sampling (CVS), usually done around 10–13 weeks, and amniocentesis, typically 15–20 weeks, can show the baby’s chromosomes and therefore sex with very high accuracy, but they carry small procedure risks and are not used just for curiosity about gender.

A simple example

If someone wants to know “how far along do you have to be to find out the gender?”:

• Going by routine care : they’ll most often find out at the 18–20 week anatomy ultrasound.
• If they choose or are offered early blood testing : they might know as early as about 10 weeks (or even a bit earlier with some consumer tests), depending on what’s available and recommended locally.
