AN46.1-5 | Introduction to Male external genitalia
The male external genitalia include the testis (with its coverings and descent), the epididymis, the penis, and the scrotum. A thorough understanding of testicular anatomy is essential for diagnosing and treating the two most urgent urological emergencies in young men — testicular torsion and incarcerated inguinal hernia. This module covers each structure with its applied anatomy, covering the most commonly tested conditions in final examinations and clinical practice.
Learning Outcomes
- Describe the coverings, internal structure, side determination, blood supply, nerve supply, lymphatic drainage, and descent of the testis with applied anatomy (AN46.1)
- Describe the parts and function of the epididymis (AN46.2)
- Describe the penis — parts, components, blood supply, and lymphatic drainage (AN46.3)
- Explain the anatomical basis of varicocele (AN46.4)
- Explain the anatomical basis of phimosis and circumcision (AN46.5)
PREREQUISITES
Review the inguinal canal and spermatic cord from the Anterior Abdominal Wall module. Understanding the coverings of the testis requires knowledge of the layers of the anterior abdominal wall.
