EXTERNAL GENTILIAEXTERNAL GENTILIA• The vulva refers to those parts that are outwardly
visible
– The vulva includes:
• Mons pubis• Labia majora• Labia minora• Clitoris• Urethral opening• Vaginal opening• Perineum

MONS PUBISMONS PUBIS• The triangular mound of fatty tissue that
covers the pubic bone• It protects the pubic symphysis• During adolescence sex hormones trigger
the growth of pubic hair on the mons pubis
UNIT 3: FEMALE REPRODUCTIVE SYSTEM
5
External organsExternal organsLabia Majora
Referred to as the outer lips– They have a darker pigmentation– Protect the vaginal and urethral openings
• Labia Manora– Referred to as the “inner lips”– Made up of erectile, connective tissue that darkens and
swells during sexual arousal
UNIT 3: FEMALE REPRODUCTIVE SYSTEM
6
CLITORISCLITORIS
• Highly sensitive organ composed of nerves, blood vessels, and erectile tissue
• It is made up of a shaft and a glans • Becomes engorged with blood during sexual
stimulation• Urethral opening is located directly below
clitoris
UNIT 3: FEMALE REPRODUCTIVE SYSTEM

VAGINAL OPENINGVAGINAL OPENINGINTROITUSINTROITUS
• Opening may be covered by a thin sheath called the hymen
UNIT 3: FEMALE REPRODUCTIVE SYSTEM
8
PERINEUMPERINEUM
• The perinium contains an abundance of nerve endings
• An episiotomy is an incision of the perineum used during childbirth for widening the vaginal opening
UNIT 3: FEMALE REPRODUCTIVE SYSTEM

INTERNAL GENITALIAINTERNAL GENITALIA• The internal genitalia consists of the:
– Vagina– Cervix– Uterus– Fallopian Tubes– Ovaries

11
VAGINAVAGINA• The vagina connects the cervix to
the external genitals• It is located between the bladder and
rectum• It functions :
– As a passageway for the menstrual flow– For uterine secretions to pass down
through the opening– As the birth canal during labor
UNIT 3: FEMALE REPRODUCTIVE SYSTEM
12
CERVIXCERVIX• The cervix connects the uterus to the
vagina• The cervical opening to the vagina is small• This acts as a safety precaution against
foreign bodies entering the uterus• During childbirth, the cervix dilates to
accommodate the passage of the fetus• This dilation is a sign that labor has begun
UNIT 3: FEMALE REPRODUCTIVE SYSTEM
13
UTERUSUTERUS• Commonly referred to as the womb• A pear shaped organ about the size of a clenched
fist• It is made up of the endometrium, myometrium
and perimetrium• Consists of blood-enriched tissue that sloughs off
each month during menstrual cycle• The powerful muscles of the uterus expand to
accommodate a growing fetus and push it through the birth canal
UNIT 3: FEMALE REPRODUCTIVE SYSTEM
14
FALLOPIAN TUBESFALLOPIAN TUBES• Serve as a pathway for the ovum to the
uterus• Are the site of fertilization by the male
sperm• Often referred to as the oviducts or uterine
tubes• Fertilized egg takes approximately 6 to 10
days to travel through the fallopian tube to implant in the uterine lining
UNIT 3: FEMALE REPRODUCTIVE SYSTEM
15
OVARIESOVARIES• The female gonads or sex glands • They develop and expel an ovum each month• A woman is born with approximately 400,000
immature eggs called follicles• During a lifetime a woman release @ 400 to 500
fully matured eggs for fertilization• The follicles in the ovaries produce the female
sex hormones, progesterone and estrogen
• These hormones prepare the uterus for
implantation of the fertilized egg
UNIT 3: FEMALE REPRODUCTIVE SYSTEM
16
BREASTSBREASTS• Contain mammary glands• Consist of connective tissue that serves as
support• Each breast contain 15-25 clusters called
lobes• Breasts may exhibit cyclical changes,
including increased swelling and tenderness prior to menstruation
• Women should complete self-examinations to change for changes or lumps

MENSTRUATIONMENSTRUATION• The onset of
menstruation signals the bodily changes that transform a female body
• Average age is 12.8• Amount of bleeding
varies from woman to woman
• Expulsion of blood clots
• Usually occurs every 25 to 32 days (cycle)
• Women can experience fluid retention, cramping, mood swings, weight gain, breast tenderness, diarrhea, and constipation

Problems related to Problems related to MenstruationMenstruation
• PMS – pre menstrual syndrome – Caused by hormonal changes– 2 weeks before menstruation– Symptoms include
• Tension• Anxiety• Irritability• Bloating• Depression• Mood swings

DYSMENORRHEA/Menstrual DYSMENORRHEA/Menstrual CrampsCramps
• Painful menstrual cramps• Painful menses without evidence of a
physical abnormality• Believed to be normal body response to
uterine contractions• Other symptoms :• Nausea, vomiting, gastrointestinal
disturbances, and fainting• Prostaglandins cause forceful, frequent
uterine contractions called cramps

fatal• Symptoms include:
– Fever– Vomiting– Diarrhea– Sunburn like rash– Dizziness– Muscle aches

Problems related to Problems related to infertilityinfertility
• Pelvic inflammatory disease PID– Infection of fallopian tubes, ovaries and
surrounding areas of pelvis– Damages reproductive organs– Usually caused by STD’s
UNIT 3: FEMALE REPRODUCTIVE SYSTEM
23
ENDOMETRIOSISENDOMETRIOSIS• Common cause of dysmennorrhea,
and infertility• Endometrium fragments and lodges
in other parts of the pelvic cavity• Causes inflammation, bleeding, and
scarring• Causes are still being studied• Treated through hormonal therapy,
or major surgical management

Other Reproductive Other Reproductive DisordersDisorders
• Cervical, Uterine, ovarian Cancer- – Early sexual activity and STD’s are related to an
increase incidence of cervical cancer– Regular check ups and exams are important for early
detection
• Ovarian cyst- fluid filled sacks on the ovary– Appear on their own– Larger cyst may require surgery– Small and non cancerous
