At what week of pregnancy can the baby's sex typically be seen?

The ability to determine the baby's sex through ultrasound typically becomes more accurate around 16 weeks of pregnancy. At this point, the developing genital structures have reached a stage of development where they can be differentiated effectively, assuming the position of the fetus is favorable for viewing. While some practitioners may claim they can make a guess as early as 12 weeks, the reliability at that point is often low, as the external genitalia are not yet fully developed enough for a clear and confident assessment.

Around 20 weeks, the sex can still be confirmed with greater accuracy, as the anatomical structures are more distinct, and detailed anatomical scans are often performed around this time. However, the timeframe closest to when the determination can be made accurately is around 16 weeks, which is why this option is considered correct. The later weeks, such as 24, typically provide no new information compared to what can be reliably assessed at 16 weeks.
