Verified step by step guidance

Step 1: Begin by understanding the anatomy of the male reproductive system. The penis is composed of several structures, including the urethra, glans, corpus cavernosum, and prepuce. Each structure has a specific function and location.

Step 2: Define the term 'prepuce.' The prepuce, also known as the foreskin, is a protective tubular sheath of skin that covers the glans (the tip of the penis). It serves as a protective layer and helps maintain sensitivity.

Step 3: Compare the other options provided in the question. The urethra is a tube that carries urine and semen out of the body, the glans is the rounded tip of the penis, and the corpus cavernosum is a pair of sponge-like regions of erectile tissue that fill with blood during an erection.

Step 4: Eliminate the incorrect options based on their definitions and functions. The urethra, glans, and corpus cavernosum do not serve as a protective sheath of skin covering the penis.

Step 5: Conclude that the correct answer is 'prepuce,' as it matches the description of a protective tubular sheath of skin covering the penis.
