You said: "They did not discuss it."
They did discuss it, albeit shortly and lined up the most important arguments both pro and contra. Honestly, you don't need any more research.

it is reasonable to put off circumcision until the age at which such a risk is relevant and the boy himself can decide about the intervention, or can opt for any available alternatives.
