>Females with DownMost are fertile, although fertility may be reduced. Also, there's a higher likelihood of passing Down syndrome on to the child (35โ50%).
I know one woman with Down who has given birth. Her husband doesn't have Down, but he has the same "mental" age as her thanks to a brain injury. Her family didn't think she was able to pregnant, so that's how she got away with it. Fortunately, their son doesn't have Down or any disability though.
