I've just watched it (not sure which channel it was on, my dp recorded it as knew I'd find it interesting).
It's a story of a boy, born with ambiguous genitalia, who was operated on as a baby to make his genitals appear to be female. His experience was so traumatic and moving (alongside stories of the other medical "experiments" in this area) and he now campaigns for the halting of these surgeries in babies and children. All conveyed really well in the documentary. Well worth a watch for anyone that hasn't seen it, but there may well be another thread discussing it.
