: Participants were informed about the study and agreed to participate verbally or via e-mail. Prior to the start of the interview, participants were informed about the interview study, its recording and the pseudonymized analysis of the interview data. All women who participated in this study gave written and verbal consent. The research protocol including the procedure for informed consent was submitted to the research ethics committee of the University Medical Center Utrecht for review prior to the initiation of the research.
