Many people have what is called Disorder of Sexual Development. (DSD).
"Several dozen conditions count as “disorders of sex development” (DSD). Remember that DSD are defined by the medical community as “congenital conditions in which development of chromosomal, gonadal or anatomic sex is atypical.” So “DSD” is an umbrella term covering a wide variety of conditions in which sex develops differently from typical male or typical female development.
How Common Is DSD?
We do know that some particular disorders of sex development are fairly rare, occurring perhaps only once in ten or twenty thousand live births. For example, the development of ovotestes is a relatively rare phenomenon. But some DSD are substantially more common. For example, hypospadias (in which the urinary opening of the penis is not in the typical location) is estimated to occur as often as once in every 150 live male births.
Estimates from specialists working in major medical centers suggest that about one in every 2,000 births at a hospital involves a child whose genitals are atypical enough to make the child’s sex unclear. But, as noted above, if we count all types of sex anomalies, DSD must be considered much more numerous than 1 in 2,000. One review estimates that about one in a hundred persons has some kind of sex anomaly.
