“…Minor regret is considered as disappointment and can overlap with dissatisfaction. In general, the literature gives high percentages of satisfaction with GAS procedures: breast augmentation 87% to 100% (De Cuypere et al, 2005;Smith, van Goozen, Kuiper, & Cohen-Kettenis, 2005;Weigert, Frison, Sessiecq, Al Mutairi, & Casoli, 2013), vaginoplasty 83% to 100% (De Cuypere et al, 2005;Horbach et al, 2015;Lawrence, 2003;Rehman, Lazer, Benet, Schaefer, & Melman, 1999;Smith et al, 2005), subcutaneous mastectomy 92% to 100% (De Cuypere et al, 2005;Nelson, Whallett, & McGregor, 2009;Smith et al, 2005), and phalloplasty 100% (De Cuypere et al, 2005).
