Mr Greenhouse trained in both venereology and gynaecology at Cambridge, aiming to bridge the gap between the disciplines. He set up the UK’s first integrated sexual health service at Ipswich in 1991. In Bristol from 1999, he won large DH grants to redesign and rebuild services there and in Weston, which won the Terrence Higgins Trust’s ‘Sex Factor’ Award for innovation & excellence in 2007.

As chair of the British Association for Sexual Health & HIV (BASHH) media committee until 2016, he led the successful campaign to switch from bivalent to quadrivalent HPV vaccination. Widely published as a medical photographer, a keen graphic designer and linguist, he lectures internationally on all aspects of women’s sexual health – particularly PID, chlamydia, herpes, HPV, perimenopause and hormonal influences on genital infections, and is a BMS-certified menopause specialist.

He served on the European Society for Contraception STI Expert Group until 2018 and is medical advisor to the ‘Great Wall of Vagina’ art project, which educates women to discourage demand for unnecessary genital cosmetic surgery. He received the Honorary Life Fellowship Award from BASHH in 2017 and wrote the chapter on sexually transmitted infections for the forthcoming edition of Dewhurst’s Textbook of Obstetrics & Gynaecology.
