“…A number of studies undertaken in various countries have explored parents' views regarding disclosure to their donor-conceived children of the means of their conception. To date, most of the study populations relating to oocyte donation have been recipients of anonymous donation whose children have been aged up to eight years (Pettee and Weckstein, 1993;Weil et al, 1994;Söderström-Anttila et al, 1998;Baetens et al, 2000;Hahn and CraftRosenberg, 2002;Greenfeld and Klock, 2004;Klock and Greenfeld, 2004;Golombok et al, 2004Murray et al, 2006;Mac Dougall et al, 2007;van Berkel et al, 2007;Laruelle et al, 2012), although one recent Finnish study has included parents of children aged up to 14 years (Söderström-Anttila et al, 2010). These studies have revealed intended disclosure rates of between 26 and 81%, although not all parents indicating an intention to disclose will necessarily do so Golombok et al, 2006;Murray et al, 2006;Mac Dougall et al, 2007;van Berkel et al, 2007), and only three studies have included longitudinal data tracking parental disclosure behaviour.…”
