"During my year in the [[Netherlands]], I was not only fascinated by paediatric urology, but also by differences in sex development – something we used to call ‘intersexuality’. This involves differences **in the three levels of sex that someone has**. "First, there is **genetic sex – your DNA** says whether you are a male or female. "Then, there is **gonadal sex – you have testicles or ovaries**. "Finally, there is **external sex – a penis or vulva**. The three levels of sex are usually the same in most people, but they can also vary in some people."
