SEXUAL ANATOMY
o
Female-External
VULVA



External portion of the female reproductive system.
Includes:
 Mons Veneris, Labia,
Vestibule,
Urethral Opening,
Vaginal Openings,
Clitoris,Introitus,
Hymen
Function:
 Protect the woman’s internal sexual organs.
 Act as a source of her sexual pleasure.
 Enhance the arousal of her partner.
VULVA

Vestibular Bulbs: (beneath the vulva)
Structures on each side of the vaginal opening that
engorge with blood and swell during sexual arousal.
 They are attached to the clitoris at the top.

MONS VENERIS

(Monis Pubis) Mound of fatty tissue over the pubic bone
above the vagina.
 Pad of fatty tissue that cushions the pubic symphysis
(slightly movable joint between the left and right pubic
bones).
 Relatively delicate and could be bruised by the impact of
sexual intercourse or riding a bicycle.
 Mons is supplied with a large number of nerve endings.
LABIA “LATIN FOR LIPS”

Extending down from the mons, the vulva includes two
prominent sets of skin folds.
 Source of sexual sensations.
 Beneath the outer folds of the labia majora is a network
of connective tissue and fat with erectile tissue under.
 Usually folded together to protect the urinary and
vaginal openings.
LABIA


Labia Minora: Form the inner lips of the vulva.
Bartholin’s Glands: Secretes a few drops of fluid during
sexual arousal.
 The few drops of fluid that they secrete during sexual
arousal are not enough to effectively lubricate the
vagina. (In most women).
VESTIBULE “ENTRANCEWAY”
Inside the labia minora.
 Rich in blood vessels and nerve endings.
 More sensitive to the touch than the labia minora.
_______________________________________________
 The labia minora meet to form a fold or small hood of skin
called the prepuce (clitoral hood)
 When the clitoris is erect and the labia minora spread, the
vestibule become visible.

URETHRAL OPENING


Duct through which urine is discharged from the bladder.
 Located below the clitoral glans.
 The urethral opening is not a reproductive organ.
Although urine and semen both pass through the male
penis, for women, urination and coitus do not occur through
the same bodily opening.
INTROITUS AND HYMEN

Introitus: Opening of the vagina
INTROITUS AND HYMEN



Hymen: Membrane that partially covers the vaginal opening.
 Thin membrane containing a large number of blood vessels.
 Annular Hymen: Surrounds the vaginal opening.
 Septate Hymen: Form a bridge over it.
 Cribriform Hymen: Appear as a sieve like covering.
Normally the hymen has an opening large enough to permit
menstrual flow or the insertion of a tampon, but too small to
permit entry of an erect penis without tearing.
Function of the hymen is unknown:
 Great deal of cultural significance.
 Presence of an intact hymen was historically considered proof
that a woman had never had intercourse.
 Intact hymen is not proof of virginity.
 Some girls are born with minimal or incomplete hymens
 Can also be ruptured by accident.
INTROITUS AND HYMEN
CLITORIS

Function is sexual pleasure:
 Clitoris is located in the vestibule at the top of the labia
minora under the prepuce.
 Average size is about 16 millimeters, approximately the
diameter of a dime.
 Considerable variation in size and shape from one
person to the next.
CLITORIS

Clitoral Glans:
 Head of the clitoris, which has a large number of nerve
endings.
 Located at the top of the clitoral shaft.
