2. What do you know about the female reproductive system
What do you know about the female reproductive system? Reproductive Systems – systems responsible for producing offspring

4. Ovaries- female sex glands
Internal Organs
Ovaries- female sex glands
produce egg (ovum)
produce estrogen and progesterone
uterus
cervix
Born about 200,000 during lifetime 400 will mature

6. Fallopian Tubes – pair of tubes fingerlike projections that draw in the ovum
pathway for egg
carries egg to uterus
fertilization takes place 90%

7. Uterus- pear shaped
- egg implants in uterine lining
- fetus grows
Endometrium – lining of uterus
Cervix- opening uterus to vagina

8. Implantation outside the uterus
Implantation inside Fallopian tube called tubal pregnancy
1 in 50 pregnancies is ectopic

9. Cervix- opening uterus to vagina
COMMON cause of cancer!
Pap smear- test cervical cancer (GYN) once a year
Vagina- Passageway from
to outside

16. Menstrual Cycle Days 1-8 Menstrual flow Days 9-13
- New egg is maturing
Lining begins to thicken
Day 14
Ovulation – mature egg is released
Days 15-28
Egg travels through fallopian tube toward uterus
Fertilization may occur

19. Care Female Reproductive System
Bathe Regularly
Abstinence from sex
Breast self exams and regular medical exams p. 455

20. Chance of dying from breast cancer is about 1 in 36
Chance of a woman having invasive breast cancer some time during her life is about 1 in 8
Chances are high the disease will touch your life, or the life of someone you know.

21. One year

22. Problems of the Female Reproductive System
Cramps – avoid salt & caffeine light exercise help
Premenstrual Syndrome (PMS) – causes by hormonal changes anxiety, bloating, depression, fatigue, weight gain exercise can help
Toxic Shock Syndrome (TSS) – bacterial infection – fever, sunburn like rash, muscle aches
- low absorbency tampon
- change tampons often

23. Infertility – cannot reproduce
Endometriosis - uterine tissue grows into uterus, abdominal cavity, or fallopian tubes
Vaginitis – bacterial infection (yeast infection)
STI
Ovarian Cysts- fluid filled sacs of ovary
Cancers

24. Male Reproduction System
Do Now:
List Secondary Sex Characteristics (changes that happen to the body during puberty) for either males or females.

25. Secondary Sex Characteristics
Male Puberty
Begins between ages 12-15
Pituitary glands sends hormones to the testes.
The testes then produce testosterone.
Secondary Sex Characteristics
Broadening of shoulders Enlargement of external organs
Development of muscles Longer heavier bones
Hair growth Increase in height
Deepening of voice Rougher tougher skin

26. Male Reproductive Organs
External Organs
Penis
Scrotum – external skin sac
Hangs from the body hold testicles
Temperature regulation

27. Male Reproductive System
Internal Organs
Testes – 2 small glands (seminiferous tubules)
- sperm production
- testosterone (hormone)
Epididymis
- sperm mature and are stored
Male Reproductive System

28. Vas Deferens
- tubes that extend from each epididymis to the urethra
Seminal Vesicle
-first stop fluid

29. Prostate Gland
- more fluid
- Common site of cancer
- Rectal exam after 40/50
Cowper’s Gland
- secrets more fluid
-Prepares urethra
Urethra
- exit for semen & urine
Semen – thick fluid containing sperm and other secretions

30. Care of Male Reproductive Systems
Regular Check ups (12 to 18 months)
Bathe regularly – thoroughly clean penis and scrotum
Protective equipment- cup or supporter
Self exams – check testicles for signs of cancer
Abstinence – Avoid STI’s

31. Problems Male Reproductive System
Hernia – intestine pushes through abdominal wall
- lifting heavy object
- lump in groin area & pain
Testicular cancer – ages common self-exam
Prostate cancer – rectal exam after 40
Sterility – inability to reproduce (Can be caused by environmental hazards, steroid use, other drug use, some medications, or diseases and STI’s
A sports hernia is a strain or tear of any soft tissue (muscle, tendon, ligament) in the lower abdomen or groin area.
