One in every 135 baby boys in Victoria is born with a form of genital abnormality, and the incidence is rising. The US and Europe are also witnessing a similar, alarming trend.
The reason for the rapid increase in the rate of genital abnormalities in male newborns is unknown, but may be due to exposure in utero to endocrine disruptors – molecules that affect the production of androgens at the critical time when the penis is forming.
Disorders of sex development are not uncommon and are part of wide spectrum, but due to the importance that society places on gender identity, the consequences can be traumatic, Professor Andrew Sinclair says.
