In an adult male, on per rectal examination, the following structures can be felt anteriorly except:
**Core Concept**
The rectal examination in an adult male involves the assessment of various structures in the perineum and pelvic floor. The anterior structures palpable during a digital rectal examination (DRE) are primarily related to the urogenital and perineal regions.
**Why the Correct Answer is Right**
The correct answer involves identifying the structures that cannot be felt anteriorly during a DRE. The prostate gland, urethra, and seminal vesicles are palpable structures in the male perineum and pelvic floor. The prostate gland is located posterior to the pubic symphysis and can be felt as a firm, smooth glandular mass. The urethra is a short, tubular structure that connects the bladder to the external urethral orifice, and it can be palpated during a DRE. The seminal vesicles are paired, tubular structures located near the base of the bladder, and they can be felt as a smooth, firm mass.
**Why Each Wrong Option is Incorrect**
* **Option A:** The prostate gland is a correct answer, but it is not the correct option to exclude. The prostate gland is palpable during a DRE.
* **Option B:** The urethra is a correct answer, but it is not the correct option to exclude. The urethra can be palpated during a DRE.
* **Option C:** This option is not listed. Please provide the complete question.
**Clinical Pearl / High-Yield Fact**
A key point to remember during a DRE is to identify the anatomic relationships between the prostate gland, seminal vesicles, and urethra. The prostate gland is surrounded by the urethra, which passes through the gland, and the seminal vesicles are located near the base of the bladder.
**Correct Answer:** A.
