“…Several studies acknowledged a close relation to a general field of "medical tourism"; however, in many cases this conceptualization was further focused on more specific niche concepts within medical tourism (Bell et al, 2011;Holliday et al, 2015;Inhorn et al, 2012;Sethna & Doull, 2012). Concepts used alongside medical tourism included, for example, those of cosmetic surgery tourism (e.g., Ackerman, 2010;Bell et al, 2011;Holliday et al, 2015Holliday et al, , 2017Jones, 2011), reproductive tourism (Arvidsson et al, 2015;Deomampo, 2013;Inhorn, 2011a;Walmsley et al, 2017), stem cell tourism (Brophy, 2017;H. Chen & Gottweis, 2013;Petersen et al, 2014), and transplant tourism (Scheper-Hughes, 2011;Wright et al, 2013).…”
