Male Reproductive System
Start with the big picture
The testes sit in the scrotum and contain seminiferous tubules, where sperm develop. Sertoli cells support developing sperm and form the blood-testis barrier; Leydig cells in the surrounding tissue produce testosterone. Sperm travel through the straight tubules, rete testis, and efferent ductules to the epididymis, where they mature and are stored before entering the vas deferens. The seminal vesicles, prostate, and bulbourethral glands add secretions, while the penis contains erectile tissues. The topic also covers the spermatic cord, scrotal and testicular coverings, vascular and lymphatic drainage, nerve supply, testicular descent, and the male urethra. These anatomical relationships provide a framework for understanding the system’s functions and clinical relevance.
What you'll learn
- Trace sperm movement from the seminiferous tubules through the reproductive ducts.
- Distinguish the roles of Sertoli cells, Leydig cells, and accessory glands.
- Identify the main erectile tissues and coverings of the penis and testes.
- Describe key vascular, lymphatic, and nerve pathways of the male reproductive system.
