Causes
Ambiguous genitalia primarily occurs when hormone abnormalities during pregnancy interrupt or disturb the fetus's developing sex organs.
How sex organs form in the womb
A baby's genetic sex is established at conception, based on the sex chromosomes. The mother's egg contains an X chromosome, and the father's sperm contains either an X or a Y chromosome. A baby who inherits the X chromosome from the father is a genetic female (two X chromosomes). A baby who inherits the Y chromosome from the father is a genetic male (one X and one Y chromosome).
Male and female sex organs develop from the same tissue. Whether this tissue becomes male organs or female organs depends on the chromosomes and the presence or absence of male hormones
