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. The best time to perform a testicular self-examination (TSE) is during or after a warm shower or bath, as warmth relaxes the scrotum, making it easier to feel for abnormalities. B. Manipulating the testicles upon rising is not an ideal time as the scrotum may be more contracted. C. Comparing both testicles concurrently is important for recognizing asymmetry but does not provide guidance on when to examine. D. Inspecting with a mirror is not necessary for TSE, as the focus should be on palpation for lumps or changes.
