Dr Anderson designed the succesful male pill and testosterone replacement implant trial at Edinburgh University in 1999 that received media attention. The trial involved the taking of a daily pill which stopped the production of sperm and testosterone. The trialists' testosterone was replaced by an implant as a tablet would have either been destroyed by the stomach (if the dosage was too small) or risked damaging the liver (if the dosage was too large).
