An Australian doctor and member of a conservative Christian sect has been banned from practicing medicine after he prescribed a teenager a chemical castration drug for use as a ‘gay cure’.

In 2008, GP Mark Craddock, prescribed the 18-year-old the anti-androgen therapy cyproterone acetate, sold under the brand name Cyprostat, during a 10-minute consultation in his home.

According to AFP, the drug is used to treat prostate cancer.
