Rights and privacy issues over human enhancement technology has given rise to challenging topics within technoself studies. For example, the consideration of ethical policies and guidelines in the deployment of HET is an emerging topic within TSS. Further, the question of access to HET, and where we draw the line between necessary therapeutic technologies, and frivolous human enhancement are being raised in TSS. Therefore, the emerging topic regarding the rights and privacy over HET is of great interest within TSS. Popular HET's topics in recent research academia include: Sex (re assignment) (Diamond & Sigmundson, 1997; Zucker, 2002), mood enhancers (Rabin, 2006), cognitive enhancers (Walker, 2008), genomics (Zwart, 2009), and neuroenhancement (Northoff,1996).
