Physician: I don’t know. I pray that there is a change. One of the things I’ve been thinking about is what puberty blockers do to children. This medication is called a “gonadotropin releasing hormone agonist” and it comes in the form of monthly injections or an implant. And because it simulates the activity of this hormone, it shuts down the activity of the hypothalamus. The hypothalamus is this almond-sized structure in your brain, it’s one of the most vestigial structures we have, and it controls all the other hormonal structures in your body—your sexual development, your emotions, your fight-or-flight response, everything. But it shouldn’t be described in such cold physiological terms because your hypothalamus is not just a hormone factory. It’s this system that allows you to stand in awe of the beauty of a sunset, or to hear the sounds of orchestral music and to stop whatever you’re doing and want to listen. And I always think that if someone were to ask me, Where is it that you would look for the divine spark in each individual? I would say that it would be somewhere “beneath the inner chamber,” which is the Greek derivation of the term hypothalamus. To shut down that system is to shut down what makes us human.
