In a male, which structures are contents of the urogenital triangle?

• A. Distal urethra, scrotum, penis, external genitalia, and perineal muscles
• B. Bladder, ureters, kidneys
• C. Ovaries and uterus
• D. Rectum and anal canal

Answer: (B)

In the male, the urogenital triangle is the anterior portion of the perineum that contains the external genitalia and the structures of the lower urinary and reproductive tract as they traverse this region. The distal urethra is included because it runs through the penis, which lies in this area, and the external genitalia—namely the penis and scrotum—are main contents of this triangle. The perineal muscles that support and move the genital structures are also housed here. Structures such as the kidneys, ureters, and bladder sit higher in the pelvis and abdomen rather than in the anterior perineal compartment, so they are not contents of the urogenital triangle. Ovaries and uterus are female organs, and the rectum/anal canal belong to the anal triangle, not the urogenital triangle.
