REPRODUCTIVE ORGAN FOR
CONTRACEPTION PORVISION

CHAPTER 2-1
OVERVIEW OF ANATOMY
2
ANATOMY OF FEMALE AND MALE
REPRODUCTIVE ORGANS
3
Outline
•The female reproductive organs:
•External organs
•Internal organs
•Physiology of female reproductive system
•The male reproductive system:
•External Organs
•Internal organs
4
Objectives
At the end of the session students will be able to:
•Identify the different parts of the female and male
reproductive organs in relation to FP
•Describe relevant physiology of reproductive organs
in relation to FP
•Review relevant anatomical issues of importance in
conducting a proper genital examination during
provision of contraception
5
Female External Organ
Mons pubis
•Triangular mound of fatty tissue that covers the pubic
bone
Labia majora
•Protect the introits and urethral openings
Labia minora
•Erectile, connective tissue that darkens &swells
during sexual arousal
Clitoris
•Highly sensitive and erectile organ made up of a shaft
& a glans
6
Female external organ …
Vestibule
•Urethral opening
•Vaginal opening
•Bartholins gland opening
•Paraurethral glands of Skene
Perineum
7
8
Female Internal organ
The female internal organ consists of :
•Vagina
•Uterus
•Ovary
•Fallopian tube
9
Female Reproductive organ
10
Vagina
•A fibromuscular cylindrical organ
• Measures from 9-11 cm in length and directed
upwards and posteriorly from the introitus
•Longer in the posterior than the anterior
11
Uterus
•A pear shaped organ
•About the size of a clenched fist - (9 X 7 X 3
cm) and weighing 50-80 gm
•Ant everted and ante flexed in position
•In some women the angle of the uterus may
be retro everted with the fundus lying in the
cul-de-sac
•Has three parts:
oCervix
o body
ofundus
12
Cervix
•Cylindrical shaped neck of tissue that
connects the vagina and the uterus
•Length ~3 cm
13
Ovaries
•On average 3 cm in length, 2 cm in breadth &
1 cm in width and weighing 4–8 gm
•Are the female gonads or sex glands (paired
organs)
•Produce the female sex hormones
(progesterone and estrogen)
•Release the ovum every month
interchangeably
14
15
Fallopian Tube
•7 -14 cm long
•Is a site of fertilization
•It is a channel through which fertilized ovum
transported to the uterus
•Divided into 3 parts:
Isthmus - narrow (1 mm diameter) and nearly straight
portion
Ampulla – wider (5-8mm) and more tortuous, it is a
site of fertilization
Infundibulum – a funnel-like structure
16
17
Adjacent structures located close to
the internal reproductive organs
•Urethra and bladder anterior to the vagina
and uterus and the rectum and cul-de-sac
located posteriorly
•The ureters also pass adjacent to the cervix
laterally
CHAPTER 2-2
OVERVIEW OF PHYSIOLOGY
19
Physiology of female reproductive
system
Four body structures are involved in the
normal physiology of female reproductive
system
•Hypothalamus
•pituitary gland
•Ovaries
•Uterus
•Cervix
20
Phases of female reproductive cycle
•Proliterative
•Ovulatory
•Secratory
•Mensturation
21
Hormones Involved
Hypothalamus hormones
•GNRH
Pituitary hormones
•FSH: follicle stimulating hormone
•LH: luteinizing hormone
Ovarian hormones
•Estrogen
•Progesterone
22
Male Reproductive Organ
24
Male External organ
•Penis
•Scrotum
25
Male Internal organ
•Has three parts
1. The testes
2. The genital ducts
3. The accessory glands
26
1. Testis
27
Testis
28
2. The Genital Ducts
•Seminiferous tubules
• Site for spermatozoa production
•Epididymis
• Cord-like structure at the back of testes
• Each connected to one of the vas deference
• Place for sperm maturation
•Vas-deferens
• A passage and storage place for sperm
• Each ends at the base of prostate, joined by the seminal
vesicle
•Ejaculatory duct
• Tract transports sperm
•Urethra
29
The accessory glands
•Provide the bulk of semen
Seminal vesicle
•Secretes fluid (Fructose and prostaglandins) that
nourishes and enables sperm to move
Prostate gland
•Secretes an alkaline fluid that neutralizes the
acidity
Bulbo-urethral (Cowper’s) glands
•Secretes a lubricant
Semen = A combination of sperm & fluid
30
Summery
•Identify the different parts of the female and male
reproductive organs in relation to FP
•Describe relevant physiology of reproductive organs
in relation to FP
•Review relevant anatomical issues of importance in
conducting a proper genital examination during
provision of contraception

  • 12. Uterus •A pear shaped organ •About the size of a clenched fist - (9 X 7 X 3 cm) and weighing 50-80 gm •Ant everted and ante flexed in position •In some women the angle of the uterus may be retro everted with the fundus lying in the cul-de-sac •Has three parts: oCervix o body ofundus 12
  • 13. Cervix •Cylindrical shaped neck of tissue that connects the vagina and the uterus •Length ~3 cm 13
  • 14. Ovaries •On average 3 cm in length, 2 cm in breadth & 1 cm in width and weighing 4–8 gm •Are the female gonads or sex glands (paired organs) •Produce the female sex hormones (progesterone and estrogen) •Release the ovum every month interchangeably 14
  • 15. 15
  • 16. Fallopian Tube •7 -14 cm long •Is a site of fertilization •It is a channel through which fertilized ovum transported to the uterus •Divided into 3 parts: Isthmus - narrow (1 mm diameter) and nearly straight portion Ampulla – wider (5-8mm) and more tortuous, it is a site of fertilization Infundibulum – a funnel-like structure 16
  • 17. 17
  • 18. Adjacent structures located close to the internal reproductive organs •Urethra and bladder anterior to the vagina and uterus and the rectum and cul-de-sac located posteriorly •The ureters also pass adjacent to the cervix laterally
  • 19. CHAPTER 2-2 OVERVIEW OF PHYSIOLOGY 19
  • 20. Physiology of female reproductive system Four body structures are involved in the normal physiology of female reproductive system •Hypothalamus •pituitary gland •Ovaries •Uterus •Cervix 20
  • 21. Phases of female reproductive cycle •Proliterative •Ovulatory •Secratory •Mensturation 21
  • 22. Hormones Involved Hypothalamus hormones •GNRH Pituitary hormones •FSH: follicle stimulating hormone •LH: luteinizing hormone Ovarian hormones •Estrogen •Progesterone 22
  • 23.
  • 26. Male Internal organ •Has three parts 1. The testes 2. The genital ducts 3. The accessory glands 26
  • 29. 2. The Genital Ducts •Seminiferous tubules • Site for spermatozoa production •Epididymis • Cord-like structure at the back of testes • Each connected to one of the vas deference • Place for sperm maturation •Vas-deferens • A passage and storage place for sperm • Each ends at the base of prostate, joined by the seminal vesicle •Ejaculatory duct • Tract transports sperm •Urethra 29
  • 30. The accessory glands •Provide the bulk of semen Seminal vesicle •Secretes fluid (Fructose and prostaglandins) that nourishes and enables sperm to move Prostate gland •Secretes an alkaline fluid that neutralizes the acidity Bulbo-urethral (Cowper’s) glands •Secretes a lubricant Semen = A combination of sperm & fluid 30
  • 31. Summery •Identify the different parts of the female and male reproductive organs in relation to FP •Describe relevant physiology of reproductive organs in relation to FP •Review relevant anatomical issues of importance in conducting a proper genital examination during provision of contraception 31
