 The DCE-Q and its addenda will be distributed by post. With regards to couples, all couples of which the woman was diagnosed with ovarian failure between October 2009 and October 2014 at the K.U.Leuven will be addressed. With regards to physicians, all physicians who indicated an interest in reproductive medicine in their membership of the Belgian Society for Reproductive Medicine BSRM will be addressed. Couples will be requested to fill out the questionnaire addenda together and to each fill out the DCE-Q separately. Physicians will be requested to fill out the questionnaire individually. The questionnaire will be coded, so that respondents who do not reply either by filling out the questionnaire or the statement of non-participation, can be send a maximum of two reminders. Prior to filling out the questionnaire respondents will be informed on the purpose of the study and provided with contact information. This way participation results in giving informed consent.
