Professional profile

Jonathan Ramsay has been a Consultant Urologist at Hammersmith, Charing Cross and Chelsea & Westminster Hospitals since 1988. He works closely with the fertility units, both at Hammersmith and Chelsea, and is also a visiting urologist to fertility clinics in Bucks, Sussex, and Central London.

Research interests and publications include methods and outcomes of sperm retrieval, vasectomy reversal and the genetic causes of infertility. Men with presumed fertility problems require individual care, diagnosis and advice, otherwise they feel abandoned by the doctors who can do so much for their partners, and sometimes they feel guilty that there seems to be so little they can do to help the situation.

My practice in men's fertility aims to answer three important questions. Firstly, is there a 'male factor' problem? Secondly, can we diagnose a cause? Thirdly, can we offer straight-forward (evidence-based) treatment?

We would normally aim to resolve these questions in 2 or 3 consultations.

Personal interests

I have been fortunate to have been able to develop a large practice in Male Fertility over the past 25-years. In 2017, 600 new patients were referred and 200 had a surgical procedure.  

Current research interests include techniques to predict spermatogenesis in non-obstructive azoospermia and fertility outcomes from men who have elected to store sperm by freezing.

In clinical practice, for men with male factor infertility, we are looking at ways to improve the DNA quality of sperm, which may improve the chances of both natural and IVF pregnancies.

Human Fertility encompasses biology, emotion and psychology, and I enjoy trying to attend to every aspect of each couple's hopes and even disappointments.

All of this is against a background of a happy family life with twin sons and a daughter, and my wife Cilla, all of whom remind me how lucky we have been in the biological lottery.
