The document summarizes the male and female reproductive systems. For males, it describes the external structures of the penis and scrotum, and internal structures including the prostate, vas deferens, epididymis, testicles, urethra, and seminal vesicles. It discusses sperm production and pathways, and disorders like prostate cancer, testicular cancer, and impotence. For females, it outlines the external structures of the mons pubis, labia, and clitoris, and internal structures of the vagina, cervix, uterus, fallopian tubes, and ovaries. It provides one example of a female reproductive disorder, endometriosis, which involves endometrial tissue growing outside the uterus

1. The Body’s Reproductive
System

2. Male Reproductive System
External Structures
• Penis: external male sex organ
- Circumcised: removes some or all of foreskin
- Uncircumcised: foreskin not removed
• Scrotum: sac of skin and muscle containing testicles
Uncircumcised Circumcised

3. Male Reproductive System

6. Male Reproductive System
Internal Structures
• Prostate: (20-30% from semen)
1. produce nutrision fluid to keep sperm stay healthy
2. Make a semen thinner for sperm swim easier
3. exocrine gland of male reproductive system
• Vas Deferens: tubes connecting epididymis to ejaculatory ducts
• Epididymis: organ where sperm matures
• Testicles: organ where sperm is created
• Urethra: tube that connects bladder to outside of body
• Cowper’s Gland: secretes lubricating fluid
• Seminal Vesicle:
1. make semen (seminal fluid) (70%)
2. Produce alkaline : neutralises the acidity of urethra and vagina
3. Provide the fructose: energy for spermatozoa
4. Provide hormone for saving semen from female immune system

12. Male Reproductive Disorders

13. Prostate Cancer
 Cancer of the Prostate
 Most Common in African
American men over the
age of 50

14. Testicular Cancer
 most common cancer
in males between the ages of
15 and 34
 highly treatable when
diagnosed early
Signs include…
 collection of fluid in the scrotum
 lump or enlargement in either testicle
 Unexplained fatigue

15. Impotence
Impotence is a common
problem among men
characterized by the
consistent inability to
sustain an erection or the
inability to achieve
ejaculation, or both.

16. Cause of Impotence

17. Female Reproductive system

18. Female Reproductive System
External Structures
 Mons Pubis: soft mound of flesh above genitals
 Labia: lip-like structures on the outside of the vagina
 Clitoris: sex organ whose sole function is pleasure

19. External Organs

20. Female Reproductive System
Internal Structures
Vagina:
1. tract from uterus to exterior
2. Birth canal and canal for the penis into vagina to deliver
sperm
3. Menstrual blood leaves the body through the vagina
Hymen: mucous membrane around vaginal opening
Cervix: lower, narrow portion of uterus
Uterus: pear-shaped organ containing growing fetus
Fallopian Tubes: pathway for egg travel during ovulation
Ovaries: egg-producing organs

21. Internal Female Reproductive Organs

22. Female Reproductive
Systems Disorders

23. • In Endometriosis, the tissue begins to grow on the outside of the uterus
• Causes: menstrual blood containing endometrial cells flows back
through the fallopian tubes and into the pelvic cavity instead of out
of the body. These displaced endometrial cells stick to the pelvic
walls and surfaces of pelvic organs, where they grow
• Symptoms include: severe pelvic pain, constipation, diarrhea
Pain when having intercourse, can cause infertility
