“…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. One of these was undertaken in Finland (Söderström-Anttila et al, 1998, 2010 and two the UK (Golombok et al, 1999;Murray et al, 2006) and (Golombok et al, 2004;Readings et al, 2011).…”
