This episode asks: Should the state be allowed to alter the biology of someone convicted of a serious sexual offence?

In the UK, a pilot scheme is offering chemical castration to certain offenders. The treatment uses medication to suppress sexual drive, and some research suggests it can reduce the risk of reoffending. Justice Secretary Shabana Mahmood recently announced plans for a national rollout, raising questions about consent, ethics, and effectiveness.

Debating the issue are Dr Alexis Paton, medical ethicist and Chair of the Committee on Ethical Issues in Medicine at the Royal College of Physicians, and UOIs Director of Research, Professor Thomas Douglas.
