The Formation of the Male Urogenital System: An In-Depth Exploration

Introduction

The development of the male urogenital system is a complex and intricate process that begins early in embryonic development. This system, which includes the urinary and reproductive organs, is essential for various physiological functions, including the excretion of waste products and reproduction. Understanding how the urogenital folds close over the urogenital opening and urethral groove to form the male urethra is crucial for comprehending normal human development as well as recognizing developmental anomalies.
