'I should have been challenged on my transition'
Keira Bell transitioned to a male when she was a teenager, taking puberty blockers provided after consultations at the Tavistock, the UK's only gender-identity development service.
The 23-year-old says she should have been challenged more by medical staff over her decision.
She stopped taking cross-sex hormones last year.
The Tavistock said it always took a cautious approach to treatment.
The clinic added that it welcomed an examination of the evidence in this contentious area.
