Prepare to discover the astonishing secrets of male anatomy you never knew existed! Jonathan from the Institute of Human Anatomy dives deep into the unique muscles found only in males: the cremaster and dartos.

Using real human cadaver dissections, we reveal the unseen forces that constantly orchestrate the movement and temperature of testicles. Understand their jaw-dropping vital role in maintaining optimal temperature for sperm production and male reproductive health.

Plus, uncover a fascinating reflex test that reveals more than just anatomy – it's used clinically, and you can even learn how to perform it (for science!). This video will fundamentally change how you see the human body and male physiology. Dive into the intricate details and surprising functions of these crucial muscles!
