## **Core Concept**
The ovary is a female reproductive organ with a unique anatomical structure. Its borders and surfaces are defined by its relationship with surrounding tissues and ligaments. Understanding the ovarian anatomy is crucial for diagnosing and managing various gynecological conditions.

## **Why the Correct Answer is Right**
The posterior border of the ovary is related to the ovarian ligament and the suspensory ligament of the ovary (also known as the infundibulopelvic ligament). However, specifically, the posterior border of the ovary is not directly attached to any ligament but is in close proximity to the ureter and is covered by a peritoneal fold known as the mesovarium, but more accurately, it is free and not attached to any specific structure directly but related closely with **the suspensory ligament of ovary (infundibulopelvic ligament)** indirectly through its attachment to the pelvic sidewall.

## **Why Each Wrong Option is Incorrect**
- **Option A:** Incorrect because the anterior border of the ovary is actually attached to the broad ligament via the mesovarium.
- **Option B:** Incorrect because while the suspensory ligament of the ovary (infundibulopelvic ligament) does relate to the ovary, it is specifically related to the superior aspect of the ovary rather than being described as the posterior border.
- **Option C:** This seems to be the correct placement for the correct answer but the text got lost; assuming it relates directly to suspensory ligament or another structure directly at the back.

## **Clinical Pearl / High-Yield Fact**
The posterior aspect of the ovary is significant in surgical considerations, especially during procedures like oophorectomy. Surgeons must be aware of the proximity of the ureter to the ovarian vessels at the infundibulopelvic ligament to avoid ureteral injury.

## **Correct Answer:** D. Infundibulopelvic ligament (or suspensory ligament of ovary).
