About us

Established in 1991, the Assisted Conception Unit at Guy's and St Thomas' has developed a reputation for excellence in both NHS and private fertility treatment. 

We are one of the leading innovators in the field of fertility and a trusted choice for people trying to conceive.

The unit is located on the 11th floor at Guy's Hospital and has recently been refurbished with state-of-the-art facilities. We have dedicated labs, theatres, and procedure rooms, all designed to be a contemporary and calming space.

Featured on the BBC and other television channels, our fertility treatments and services are led by world renowned clinicians.

You will be treated by a team of experts who are constantly researching and innovating the field of fertility and in particular IVF. The techniques that we have developed have been implemented by clinics around the country. At the Assisted Conception Unit at Guy's and St Thomas' you will be able to access treatments by the people who developed them.

We are also the largest and most successful clinic in the UK for pre-implantation genetic diagnosis (PGD) and are licensed to carry out stem cell research.

We are proud to say that our commitment to pioneering research and the expertise of our clinicians has given us good success rates, helping to increase your chances of conception.
