In this chapter, I argue that an ontological duality of egg donors is enacted in fertility clinics, distinguishing between the biographical subject and the body object. Here, I focus on the delimitation, selection, and taming of the biographical subject—enacted as potentially unreliable and therefore requiring containment. I argue that, to ensure cycle completion, clinics have in place taming techniques that combine methods of control and care. These practices are aimed at managing donors’ perceived unpredictability and fragile lives, which are understood as markers of class, age, and race. In this context, taming emerges both as a relational and as an explicitly economic activity, infused with gendered labor.
