Both clinical sites use an in-house developed database which allows for an historical overview of trials per subject and a follow-up of individuals. Per site approximately 3000 actively participating healthy young volunteers are included in the database. In addition, the sites have access to postmenopausal women and to special populations, e.g. obese women, lactating women, women with dysmenorrhoea, acne, premenstrual syndrome or premenstrual dysphoric disorder. Subject recruitment is performed by the medical staff. The recruitment response is intensively monitored and recruitment strategies are adapted immediately, if required, depending on the response.
