Welcome to the ultimate guide to penile anatomy, where we take a medical and educational deep dive into the inner workings of one of the most fascinating organs of the human body. Led by Dr. med. Dr. phil. Stefan Buntrock, a board-certified urologist and specialist in sexual health from Göttingen, this video explains the intricate details of the penis, from its erectile tissue to the critical roles of its arteries, veins, muscles, and nerves.

We’ll explore how the corpora cavernosa and corpus spongiosum work together during an erection, what makes the penis rigid despite the absence of a bone, and how structures like the tunica albuginea and the fibro-skeleton provide stability and strength. You'll learn why the glans penis behaves differently during an erection and how the bulbospongiosus and ischiocavernosus muscles trap blood to sustain firmness. This video also explains the role of pelvic floor muscles and how the neurovascular bundle, the penis’s delicate supply lines of blood and nerve signals, is protected.

We’ll also address the foreskin, or prepuce, as more than just a piece of skin. The frenulum and the thousands of nerve endings in the foreskin contribute to penile sensitivity, providing both mechanical protection and sensory functions. The discussion touches on the impact of circumcision, weighing the potential effects on sensitivity and sexual function, as well as the conditions that may necessitate foreskin removal, such as BXO (balanitis xerotica obliterans) or lichen sclerosus.

This video is designed to be a comprehensive, fact-based overview for those interested in anatomy, urology, and sexual health education. With high-quality medical illustrations and a straightforward explanation of how an erection works, this content is perfect for anyone curious about the science behind the penis.

Tunica albuginea

* Most important for keeping the blood inside the penis is the Tunica albuginea because it locks the penile veins

Neurovascular Bundle

* it's crucial for you to know the main supply lines, there is a bundle containing a MAJOR ARTERY, VEIN and NERVE running together on the BACK of the PENIS this is a VERY DELICATE STRUCTURE and if it gets DAMAGED the PENIS WILL LOSE A LOT of ITS FUNCTION this POWER LINE has a name of it's own the NEUROVASCULAR BUNDLE, the neurovascular bundle is WELL PROTECTED because there are SEVERAL LAYERS OF TISSUE covering up that STRUCTURE

Understanding Your Hormones

Estradiol (E2)

A form of estrogen produced from testosterone. Important for bone health, mood, and libido. Too high can cause side effects; too low can affect well-being.

DHT

Dihydrotestosterone is a potent androgen derived from testosterone. Affects hair growth, prostate health, and masculinization effects.

Free Testosterone

The biologically active form of testosterone not bound to proteins. Directly available for cellular uptake and biological effects.
