The college health clinic nurse is preparing a seminar on testicular self-examination (TSE). Which instruction should be included in the content for this seminar?

A. Manipulating the testicles upon rising is not a recommended time for TSE and could lead to unnecessary manipulation that doesn't focus on examination. B. Inspecting the testicles using a mirror is not as effective as feeling for lumps and abnormalities through touch. C. It is ideal to perform testicular self-examination during bathing, as the warm water relaxes the scrotal skin and makes it easier to detect any lumps or changes in texture. D. Comparing both testicles concurrently is important, but the technique is not as effective when done without the warmth of a bath or shower.
