Its aim is to identify and review the results of good quality health research and to disseminate actively the findings to key decision makers in the NHS and to consumers of health care services. In this way health care professionals and managers can ensure their practice reflects the best available research evidence. The reviews will cover: the effectiveness of care for particular conditions; the effectiveness of health technologies; and evidence on efficient methods of organising and delivering particular types of health care.

The main objectives were: 1. To examine the clinical effectiveness and safety of parenteral oestrogen therapy in prostate cancer. 2. To examine the relationship between dose and efficacy and safety of parenteral oestrogen in prostate cancer. 3. To compare the safety profile of oestrogen given transdermally with other routes of administration, in males or male-to-female transsexuals with any condition. Methods Search strategy Eighteen electronic databases including EMBASE and MEDLINE were searched from inception to March 2004. Appropriate paper and internet resources were also searched. Inclusion/exclusion criteria Objective 1: Randomised controlled trials of parenteral oestrogen compared with any treatment in patients diagnosed
