Round ligament

A vital connective tissue structure that supports the uterus during pregnancy.
The round ligament is a fibrous cord that extends from the uterus to the labia majora and plays a crucial role in anchoring the uterus in place. These ligaments are primarily composed of smooth muscle fibers and connective tissue. They help maintain the position of the uterus by holding it in an upright position within the pelvic cavity.

Reproductive system
Function
The primary function of the round ligament is to provide support and stabilization to the uterus, especially during the growth of the uterus throughout pregnancy. As the uterus expands, the round ligament stretches to accommodate this growth while maintaining its connection to the pelvic wall. Moreover, it contains nerve endings that may contribute to the perception of pain or discomfort as the ligaments tighten, particularly in late pregnancy or during certain movements. This property is essential for the pregnant individual as it helps adapt to the dynamic changes occurring in the body.
Location
The round ligaments lie within the broad ligament of the uterus and run laterally from the uterus towards the inguinal canal. They originate at the uterine horns, situated near the upper part of the uterus, before following a path through the pelvic region. The ligaments traverse beneath the peritoneum, a membrane that lines the abdominal cavity, and continue towards the labia majora, which are external structures of the female genitalia. Their strategic positioning allows them to effectively support the uterus while accommodating the significant spatial changes imposed by fetal development.
Did You Know?
  • During pregnancy, the round ligaments can cause a sharp pain known as round ligament pain, which many experience as the ligaments stretch.
  • Though primarily associated with the female reproductive system, the concept of round ligaments is observed in both sexes in various forms, although their significance varies.
  • The round ligament does not perform a direct role in fertility; however, its structural integrity is critical for maintaining an optimal uterine environment for conception and fetal development.
