3. IMPORTANCE OF SYSTEM:
 The primary function of the female reproductive system is to produce the female egg
cells which are essential for reproduction.
It is important to know that the entire system is designed for transporting the ova to
the exact fertilization site.
The female reproductive system is responsible for producing female sex hormones
which maintain the reproductive cycle.

4. INTRODUCTION
• Sexual life in females
• FIRST PERIOD
• It Extends From Birth To Puberty
• SECOUND PERIOD
• From Menarche To Menopause
• THIRD PERIOD
• From Menopause To Rest Of The Life

5. PUBERTY
• Puberty is the period of the time when secondary sexual characters begin to devolop
• In females puberty starts at the age of 12
• when First menses appears that is considered to be puberty
• Changes occurred are
• Development of pubic hair
• Development of axillary hair
• Development of breast
• Development of sexual organs
• Change in voice
• Increased levels of hormones

UTERUS
VAGINA

9. ORGANS INVOVED IN THE SYSTEM
• MONS PUBIS:
• It is a round eminence present in front of the
pubic symphysis
• It is formed by the accumulation of the sub
cutaneous fat
• It is covered by the skin and the pubic hair
• Labia majora:
• The two longitudinal folds of the skin
enclosing fat which are extending from the
mons pubis
• They are covered by pubic hair externally
and internally they contain sebaceous glands

10. • Labia minora
• Medial to the labia majora there are two
small folds of the skin called as labia
minora
• Labia minora is devoid of the pubic hair
and fat.
• There are having numerous of the
sebaceous glands
• Clitoris:
• It is the small cylindrical mass of the
erectile tissues and the nerves located in
the anterior junction of the labia majora
• It corresponds to the penis of the males

11. • VESTIBULE
• The cleft between the labia majora is
called as the vestibule
• It mainly contains the
• Hymen
• Vaginal orifice
• external urethral orifice
• Openings of the several ducts
• Hymen :
• Thin mucous layer which partially
occludes the vaginal opening.
• Vaginal orifice :
• It is the opening of vagina from the exterior

12. INTERNAL GENITAL ORGANS

13. • OVARIES :
• These are female gonads
• These are paired present in the upper pelvic
cavity
• These are flattened ovarian bodies with
dimension of the 4cm( Length), 2cm ( width),
1cm ( thickness)
• Each ovary are attached at hilum by the
ligaments called ovarian ligaments, broad
ligaments , mesovarium ligaments
• Mesovarium gives rise to the germinal
epithelium
• Each ovary shows
• (1) medulla
• (2) cortex

14. • Each ovary consists of the :
• Germinal epithelium
• Tunica albuginea
• Stroma
• Ovarian follicles
• Graafian follicle
• Corpus luteum
• Interstitial cells

15. FUNCTIONS OF THE OVARIES:
Ovaries produces ova the female gamete by the
OOGENESIS
Ovaries produces the hormones like
ESTROGEN
PROGESTROGEN
RELAXIN
INHIBIN

16. OOGENESIS
• At the 7th or 8th month
of the intrauterine life
about 6 primordial
follicles are found in
the ovary
• But the time of the
birth there are only 1
million are seen
• At the time of the
puberty there are
3,00,000 to 4,00,000

17. OVARIAN HORMONES
• ESTROGEN :
• It is secreted by the theca interna cells of the ovarian
follicles
• The secretions of estrogen is predominant in the later
stage of follicular phase before ovulation.
• Function:
• promote cellular development
• Growth of ovarian follicles
• Increase in the spontaneous activity of uterine
muscles and sensitivity to oxytocin
• Increase the activity of cilia
• Reduces the PH of the vagina causing more acidity
• Development of breast
• Estrogen increases osteoblastic activity

18. PROGESTERONE
• It is secreted by the ovaries during the follicular stage
FUNCTIONS:
Promotes secretory activities of the uterine endometrium
Promotes secretory activities of the mucosal lining of the fallopian tubes
Promotes the development of the lobules and alveoli of the breast
Increases the reabsorption of the sodium and water

19. UTERINE TUBES
• Also called fallopian tubes
• They are two in number attached on either
side of the uterus
• Uterine tubes extend laterally from uterus to
ovaries
• Each uterine tube has been divided into
• Infundibulu
m
• Ampulla
• Isthmus

20. HISTOLOGY:
• MUCOSA
• MUSCULARIS
• SEROSA
• Mucosa is the innermost layer contains of ciliated
columnar epithelium
• Helps to move the secondary oocyte along tube
• Muscularis helps in the peristaltic movement
• Serosa lines the outer most layer

21. FALLOPIAN TUBES

22. UTERUS:
• It is pear shaped hallow muscular organ
• It is situated in the pelvic cavity between the urinary bladder and
rectum
• It is 3” length, 2” width,1” thickness and 30-40 mgs weight
• Uterus is having
• FUNDUS
• BODY
• CERVIX
• Fundus is dome shaped present above the level of the
openings of the fallopian tube in uterus
• Body is middle portion of the uterus

23. • CERVIX :
• Inferior narrow portions of the
uterus
• It has two openings on either
sides
• Opens into uterus by internal os
• Opens into vagina by means of
external os
• Narrow canal is called as cervical
canal

24. WALL OF UTERUS:
• The wall of uterus is composed of
• Perimetrium
• Myometrium
• Endometrium
• Perimetrium is the outer most layer of the uterus
• Myometrium is middle layer made up of the smooth
muscle
• Endometrium is the inner most layer which is
highly vascular
• Stratum functionalis
• Stratum basalis

25. FUNCTIONS
• Serves as the pathway for the sperms to
reach the fallopian tube
• Uterus is site of menstruation
• Site of implantation of the fertilised egg
• Site of development of foetus during
pregnancy
• to provide blood supply to the ovaries

26. VAGINA
• Vagina is a fibromuscular canal lined by
the mucous membrane
• It is the female copulatory organ
• The diameter of the vagina increases2.5
cm to 5 cm
• It is situated posterior to the urinary
bladder and urethra
• At the lower end it is having hymen
• These acids create a low ph which retards
the microorganisms

27. FUNCTIONS
• It receives semen from the penis
during sexual intercourse
• Serves as a passage way for the
menstrual flow
• Serves as a passage way for baby
during child birth
• It secretes mucous for the lubrication

28. MAMMARY GLAND
• These are the modified sweet glands produces the milk
• These are present in both sexes but developed in females
• These are 2 in number present in pectoral regions
• These contain lobules alveoli
alveoli secondary tubules
secondary tubules mammary
glands
Mammary glands lactiferous
sinus
lactiferous sinus lactiferous
ducts
lactiferous ducts nipple

29. MENSTRUAL CYCLE
• The menstrual cycle is the regular natural change that occurs
in the female reproductive system
• The menstrual cycle starts with the first day of the period and
ends when the next period begins
• Hormone signals are sent back and forth between the brain and
the ovaries, causing changes to the sacs in the ovaries that
contain eggs (follicles) and the uterus
• The first part of the cycle prepares an egg to be released from
the ovary and builds the lining of the uterus
• The second part of the cycle prepares the uterus and body to
accept a fertilized egg, or to start the next cycle if pregnancy
doesn’t happen

30. • There are three phases
• Menstrual PHASE– first 5 days
• PRE OVULATORY PHASE 6th to 13th
day
• OVULATION – 14TH day
• POST OVULATORY PHASE

31. PREGNANCY
• It is sequence of events
• Fertilisation
• Implantation
• Growth of
embryo
• Fatal growth
• Delivery

32. • Fertilisation
• The process of union of male and
female gametes
• Out of million of sperms only
few i..e 1% reach the egg
• Sperm under goes capacitation
and penetrates in to the ova

33. IMPLANTATION
• In humans, implantation is the stage of
pregnancy at which the embryo adheres to
the wall of the uterus.
• At this stage of prenatal development, the
conceptus is called a blastocyst. It is by this
adhesion that the
• Embryo receives oxygen and nutrients from
the mother to be able to grow

34. EMBRYONICAL DEVOLOPMENT
• First two months of the development is called as embryonic devolpment
• During this period it is called as fetal period

35. • Pregnancy
• It is diagnosed by GRAVINDEX
TEST
• It is having three trimesters
• First trimester
• Second trimester
• Third trimester

36. • Amenorrhoea
• Morning sickness
• Salivation and changes in
disposition
• Irritability of bladder

37. SECOND TRIMESTER
• Pigmentation
• Changes in the shape and size of the uterus
• Intermittent uterine contractions
• Active fetal growth
• Palpation of fetal parts

38. THIRD TRIMESTER
• Pain less uterine contractions
• Fetal movements are easily known
• Uterine cavity enlarges

40. LABOUR
• STAGE OF DILATION
• STAGE OF EXPULSION
• STAGE OF PLACENTA

42. PATHO PHYSIOLOGICAL CHANGES
Polycystic ovary syndrome
• Polycystic ovary syndrome, widely known as PCOS, is an endocrine system disorder that
affects women in their reproductive years. Small fluid-filled sacs develop on the ovaries. It
is also known as or Stein-Leventhal syndrome
• symptoms
• irregular menses
• excess androgen levels
• sleep disturbances
• high stress levels
• high blood pressure
• skin tags
• infertility

43. • DIAGNOSIS:
• if women have at least two of three main symptoms — high androgen levels,
irregular periods, and cysts in the ovaries. A pelvic exam, blood tests, and
ultrasound can confirm the diagnosis.
• TREATMENT:
• Maintain a healthy weight. Weight loss can reduce insulin and androgen
levels and may restore ovulation.
• Limit carbohydrates. Low-fat, high-carbohydrate diets might increase
insulin levels.

44. SOME OF THE CANCERS
• Cervical cancer :A malignant tumour of the cervix , the lowermost part of the uterus.
• Ovarian cancer :A cancer that begins in the female organs that produces eggs.
• Uterine cancer :A type of cancer that begins in the uterus.
• Vaginal cancer :It occurs in the cells that line the surface of vagina.
• Vulva cancer :A type of cancer thar occurs on the outer surface area of female.
• Breast cancer : A cancer that forms in the cells of the breast
