Clinical and Research Interest

Clinical Interest:

Dr Christopoulos is an accredited specialist in laparoscopic gynaecological surgery and his special interests include reproductive endocrinology, menopause and the management of male infertility. As an NHS Consultant at University College Hospital and a clinical director at Thames Valley Fertility he has helped thousands of women and couples going through fertility treatment including IVF, ICSI, oocyte donation and fertility preservation. His philosophy has always been to tailor medical treatment to the individual needs of women and couples through a clear and evidence-based approach.

Research Interest:

Mr Christopoulos has significant research background. He has published extensively in the field of assisted conception and his research interests include uterine fibroids, polycystic ovarian syndrome and the prevention of ovarian hyper stimulation syndrome. His MD at Imperial College London focused on the use of novel medication, which aimed to decrease complications and improve the safety profile of IVF cycles. This research project received widespread attention from the scientific community and the media both at national and international level.
