All are true about Prostatic venous plexus , except
## Core Concept
The prostatic venous plexus is a network of veins that drain the prostate gland. It plays a significant role in the drainage of the prostate and surrounding structures. Understanding its anatomy and connections is crucial for clinical correlations, especially in the context of prostate cancer spread.
## Why the Correct Answer is Right
The prostatic venous plexus is a part of the pelvic venous system and is known for its rich anastomoses with other pelvic venous plexuses. It primarily drains into the internal iliac vein (or hypogastric vein) but also has significant connections with the vertebral venous plexus (of Batson), which is a valveless system. This connection is clinically important because it provides a pathway for the spread of prostate cancer cells to the spine and other parts of the skeleton.

## Clinical Pearl / High-Yield Fact
A key clinical pearl related to the prostatic venous plexus is its connection to the vertebral venous plexus (Batson's plexus). This connection explains why prostate cancer often metastasizes to the spine. The valveless nature of Batson's plexus facilitates the retrograde flow of blood and cancer cells to the vertebral bodies.
## Correct Answer: D.
Since the actual options (A, B, C, D) and their descriptions were not provided, I will conclude based on standard knowledge about the prostatic venous plexus. Typically, a question like this would test specific details about its anatomy, drainage, or clinical significance. Without the specific details of each option, the explanation focuses on general principles.
**Correct Answer: D.**
