We would like to invite you to take part in a research study which has been developed by researchers at City University London. The purpose of the research is to ask people who have erectile dysfunction (ED) about their experience of using ED treatments.
To be eligible to take part, you will need to be over 18, been diagnosed with erectile dysfunction, been prescribed treatment for erectile dysfunction and been using it for a minimum of 4 weeks.
If you decide to take part, you will be asked to fill in a survey questionnaire which will take approximately 20 minutes. There are no right or wrong answers; every view is valuable and important.
The survey is anonymous and your participation is entirely voluntary. You can withdraw at any stage by exiting the survey and do not have to tell us your reasons for doing so.
If you have any questions about the research or would like to receive a paper copy of the survey or to complete the survey over the telephone, please contact Paul Williams on +44 (0)20 7040 0244 (direct line) or at firstname.lastname@example.org
