We analyze the gender discourses that come into play when surgeons are asked to distinguish between 3 cases of breast surgery: breast implantation for transsexual women, postmastectomy breast intervention, and breast augmentation for aesthetic reasons. In the surgeons’ discourses, the 3 interventions are situated in the reconstruction/cosmetic divide. However, we can see that this boundary is profoundly influenced by cultural conceptions of gender. These gendered conceptions affect what is labeled normal/abnormal, what demands are considered legitimate, and which bodies are deemed able to possess certain attributes.
