The Male Reproductive System

Overview

The male reproductive organs within the pelvis support sperm production, storage and delivery, as well as seminal fluid secretion. This section introduces the major structures of the male reproductive tract and their functional organisation. These organs interact closely with urinary pathways and endocrine control.

Key Structures

Topics include the penis, testes and epididymis, scrotum, spermatic cord, prostate gland, bulbourethral glands and seminal vesicles, with emphasis on relationships, ducts and functional anatomy.

Clinical Relevance and Learning Focus

Knowledge of male pelvic anatomy is crucial for assessing infertility, prostate disease, torsion, hernias and congenital anomalies. This section also supports understanding of vasectomy, catheterisation and prostate examination.
