Which ligament attaches the ovary to the pelvic sidewall?

• A. Suspensory
• B. Ovarian
• C. Broad
• D. Cardinal

Answer: (A)

The key idea is which structure physically anchors the ovary to the pelvic sidewall and carries its vessels. The suspensory ligament of the ovary (also called the infundibulopelvic ligament) does this job: it extends from the ovary to the lateral pelvic wall and contains the ovarian vessels and nerves. That lateral attachment is what defines it as the ligament linking the ovary to the sidewall.

The other ligaments have different roles: the ovarian (utero-ovarian) ligament connects the ovary to the uterus; the broad ligament is a peritoneal fold supporting the uterus, tubes, and ovaries but not a specific sidewall attachment; and the cardinal (transverse cervical) ligaments attach the cervix to the pelvic wall, not the ovary.
