Your medical team will likely be the first to recognize ambiguous genitalia soon after your baby is born. Occasionally, ambiguous genitalia is diagnosed before birth (prenatally). Characteristics can vary in severity, depending on when during genital development the problem occurred and the cause of the disorder.
Babies who are genetically female (with two X chromosomes) may have:
- An enlarged clitoris, which may resemble a small penis
- Closed labia, or labia that include folds and resemble a scrotum
- Lumps that feel like testes in the fused labia
Babies who are genetically male (with one X and one Y chromosome) may have:

- The absence of one or both testicles in what appears to be the scrotum
- Undescended testicles and an empty scrotum that has the appearance of a labia with or without a micropenis
