I have only just noticed this but in the video where the Australian doctor examines the testes with an orchidometer, https://vimeo.com/114632769 , I think she tests the patient’s cremasteric reflex as soon as the camera focuses on the genitalia. If you look closely her right hand does appear to be on his thigh, albeit out of shot, and the way his testicles retract would suggest she elicited a strong response!
Could anyone with more knowledge confirm this?
