This paper argues that infertility can result in a range of negative emotional reactions, including a lack of confidence. This is more marked when donor insemination (DI) is used because of the additional shame this is associated with. Parents who do not feel confident may be less likely to share information about their use of DI with others and their child. Legislation in several countries has been introduced to abolish donor anonymity, but this has does not necessarily have an impact on parental confidence. In order to evaluate whether educational preparation programmes can impact on parental confidence and their intention to share information about DI, the confidence levels of 60 participants of three seminars were examined at three different points in time: before, immediately after and several months after attending the programme. Results indicate that most participants' confidence increased markedly as a result of attending an educational seminar. Furthermore, this increased confidence also impacted positively on the intention to share information about DI with future children. Both remained high several months after having attended the programme. These results point out that group preparation programmes can enhance levels of confidence, both as treatment is begun and as family building is undertaken.
