Female Reproductive System: Comprehensive Anatomy of Internal and External Genitalia
The female reproductive system represents a complex integration of internal and external structures designed for reproduction, sexual function, and hormonal regulation. This detailed sagittal view provides medical professionals with essential insights into the anatomical relationships between reproductive and urinary structures, crucial for understanding both normal physiology and pathological conditions.
Uterine tube The uterine (fallopian) tubes extend laterally from the uterine cornua to the ovaries. These 10-12 cm long structures contain specialized ciliated epithelium that facilitates egg transport and provides an optimal environment for fertilization.

Infundibulum The infundibulum forms the funnel-shaped opening of the fallopian tube. This specialized structure contains fimbriae that actively sweep over the ovarian surface to capture released oocytes.
Ovary The ovaries are paired endocrine organs producing eggs and hormones. These almond-shaped structures produce estrogen (E2), progesterone (P4), inhibin A/B, and contain approximately 1-2 million primordial follicles at birth.
Uterus The uterus is a thick-walled, pear-shaped muscular organ situated in the pelvic cavity. This remarkable organ can expand up to 500 times its normal size during pregnancy while maintaining structural integrity.
Endometrium The endometrium is the inner mucosal layer of the uterus. This dynamic tissue undergoes cyclic changes in response to hormonal signals and consists of functional and basal layers.

Bladder The urinary bladder is a muscular organ situated anterior to the uterus. This distensible organ can expand from 50ml to 500ml capacity and maintains intimate anatomical relationships with the anterior vaginal wall.
Cervix The cervix is the lower cylindrical portion of the uterus connecting to the vagina. This structure measures 2.5-3 cm in length and undergoes significant changes during the reproductive cycle.
Vagina The vagina is a fibromuscular canal extending from the vulva to the cervix. This elastic organ measures 7-9 cm in length and maintains a complex microbiological environment.
Urethra The female urethra is a 4cm long tubular structure extending from the bladder to the external meatus. This canal contains both smooth and striated muscle and is intimately associated with the anterior vaginal wall.
Crus of clitoris (corpus cavernosum) The crura are the paired proximal extensions of the clitoral body. These erectile structures attach to the pubic arch and contain specialized vascular tissue.
Greater vestibular (Bartholin’s) gland The Bartholin’s glands are paired structures located in the posterior vestibule. These glands secrete mucus during sexual arousal and help maintain optimal vaginal pH.
Clitoris bulb (corpus spongiosum) The clitoral bulbs are paired erectile bodies located along the vaginal opening. These structures become engorged during sexual arousal and contribute to sexual response.
Prepuce (clitoral hood) The prepuce is a fold of skin that covers and protects the clitoral glans. This structure contains numerous nerve endings and specialized sensory receptors.
Glans of clitoris The clitoral glans is the external portion of the clitoris containing over 8,000 sensory nerve endings. This highly innervated structure plays a crucial role in sexual response and pleasure.
Labia majora The labia majora are the outer folds of the vulva containing adipose tissue and sebaceous glands. These structures provide external protection and undergo changes during sexual maturation.
Labia minora The labia minora are thin, hairless folds of tissue flanking the vaginal opening. These highly vascularized structures contain numerous nerve endings and protect the vaginal and urethral openings.
Paraurethral (Skene’s) gland The Skene’s glands are located on either side of the urethra. These structures produce secretions during sexual activity and are considered homologous to the male prostate.
Hymen The hymen is a membrane of variable thickness partially covering the vaginal opening. This structure varies considerably in appearance and configuration among individuals.
Vaginal opening The vaginal opening represents the entrance to the vaginal canal. This region is highly innervated and surrounded by the bulbocavernosus muscles.
Urethral opening The external urethral meatus is located anterior to the vaginal opening. This small opening is surrounded by specialized epithelium and protective glands.
Female Reproductive Anatomy: A Comprehensive Guide
Anatomical Organization
The female reproductive system demonstrates complex integration between internal and external structures. Each component maintains specific spatial relationships crucial for reproductive and sexual function while sharing intimate associations with the urinary system.
External Genitalia
Vulvar Structures
The vulva comprises multiple specialized components:
- Labia majora and minora
- Clitoral complex
- Vestibular glands
- Urethral and vaginal openings
Internal Organs
Reproductive Tract
The internal reproductive organs form a continuous pathway:
- Vaginal canal
- Cervical canal
- Uterine cavity
- Fallopian tubes
These structures undergo cyclic changes in response to hormonal fluctuations.
Pelvic Support
The reproductive organs are maintained by:
- Pelvic floor muscles
- Ligamentous attachments
- Fascial supports
- Vascular pedicles
Clinical Applications
Diagnostic Considerations
Modern assessment methods include:
- Physical examination
- Imaging studies
- Laboratory testing
- Functional evaluation
Therapeutic Approaches
