Female Reproductive System: Ligaments and Supporting Structures (A Surgical Anatomy Guide)
The female reproductive system’s structural integrity relies on an intricate network of ligaments and supporting tissues that maintain proper organ positioning while allowing necessary mobility. This detailed anatomical illustration highlights the crucial supporting structures of the uterus and adnexa, essential knowledge for gynecological surgeons and medical professionals.

Ligament of ovary The ovarian ligament is a fibrous cord connecting the ovary to the lateral uterine wall. This structure contains smooth muscle fibers and serves as a crucial anchor point while allowing appropriate ovarian movement during reproductive processes.

Uterus The uterus is a thick-walled, pear-shaped muscular organ situated in the pelvic cavity. This organ demonstrates remarkable plasticity during pregnancy while maintaining its structural position through complex ligamentous attachments.
Uterine tube The uterine (fallopian) tube extends laterally from the uterine cornua toward the ovary. This muscular tube measures 10-12 cm in length and is supported by the mesosalpinx portion of the broad ligament.
Epoöphoron The epoöphoron is a vestigial remnant of the embryonic mesonephric tubules. This structure is located in the mesosalpinx and may become clinically significant in certain pathological conditions.
Ostium abdominale The abdominal ostium is the fimbriated end of the fallopian tube. This specialized opening creates a direct communication between the peritoneal cavity and the female reproductive tract.

Ovarian fimbria The ovarian fimbriae are finger-like projections at the distal end of the fallopian tube. These delicate structures actively sweep over the ovarian surface to capture released oocytes during ovulation.
Ovarian vessels The ovarian vessels include both arterial and venous components that provide blood supply to the ovary. These vessels course through the infundibulopelvic ligament and are crucial considerations during surgical procedures.
Broad ligament The broad ligament is a peritoneal fold that supports the uterus, fallopian tubes, and ovaries. This complex structure contains several components including the mesosalpinx, mesovarium, and mesometrium.
External uterine orifice The external uterine orifice represents the opening of the cervix into the vagina. This structure undergoes significant changes during the menstrual cycle and dramatically transforms during childbirth.
Surgical Anatomy of Female Reproductive Support Structures
Anatomical Organization
The female reproductive organs maintain their position through a complex system of ligaments and peritoneal reflections. These supporting structures provide both stability and flexibility, allowing for normal physiological functions while preventing organ displacement.
Ligamentous Support System
Primary Ligaments
The uterus and adnexa are supported by several key ligaments:
- Round ligaments
- Broad ligaments
- Cardinal ligaments
- Uterosacral ligaments
These structures work together to provide three-dimensional support while allowing necessary movement during pregnancy and daily activities.
Vascular Considerations
The reproductive organs receive blood supply through multiple sources:
- Uterine arteries (branches of internal iliac)
- Ovarian arteries (direct branches of aorta)
- Vaginal arteries
- Extensive anastomotic networks
Clinical Applications
Surgical Implications
Understanding ligamentous anatomy is crucial for:
- Hysterectomy procedures
- Fertility operations
- Cancer surgeries
- Pelvic floor repairs
Pathological Considerations
Common structural disorders include:
- Uterine prolapse
- Ovarian torsion
- Broad ligament cysts
- Endometriosis
Advanced Concepts
Embryological Development
Support structures develop from:
- Müllerian ducts
- Urogenital ridges
- Peritoneal reflections
- Mesonephric remnants
Biomechanical Properties
Ligamentous support provides:
- Dynamic stability
- Elastic deformation
- Tensile strength
- Structural integrity
