In female patients, which organ is commonly trapped in the inguinal sac?

The ovary is commonly the organ that can become trapped in the inguinal sac in female patients. This condition, known as an inguinal hernia, occurs when abdominal contents protrude through the inguinal canal, which can include a descended ovary. When an inguinal hernia presents in females, the ovary can slide into the inguinal canal due to its proximity and anatomical relationships.

This understanding is crucial in surgical practice as recognizing the symptoms and signs of this complication can guide surgical intervention. Other structures such as the uterus, fallopian tube, and cervix typically do not traverse the inguinal canal due to their position within the pelvic cavity, making the ovary the most common organ involved in this specific scenario.
