The broad ligament is a sheet of visceral peritoneum which drapes over the uterus and uterine tubes. Laterally, it is continuous with the peritoneum of the lateral pelvic wall. The ovary is not covered by peritoneum, but is attached to the posterior surface of the broad ligament by a peritoneal sleeve, called the mesovarium, which conveys the ovarian blood vessels and lymphatics. The ovarian vessels form a fold in the lateral part of the broad ligament known as the suspensory ligament of the ovary. The round ligament (of the uterus) and (round) ligament of the ovary are also contained within the broad ligament. The part of the broad ligament between the mesovarium and uterine tube is sometimes referred to as the mesosalpinx and that immediately lateral to the uterus is known as the mesometrium.
