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

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

Fallopian Tubes – pair of tubes fingerlike projections that draw in the ovum
• pathway for egg• carries egg to uterus fertilization takes place 90%
![Page 7: Chapter 16 Lessons 2 & 3 -Female Reproductive System -Male Reproductive System](https://reader035.vdocuments.us/reader035/viewer/2022081511/56649cb65503460f9497a72c/html5/thumbnails/7.jpg)
Uterus- pear shaped- egg implants in uterine lining
- fetus grows
Endometrium – lining of uterus
Cervix- opening uterus to vagina
![Page 8: Chapter 16 Lessons 2 & 3 -Female Reproductive System -Male Reproductive System](https://reader035.vdocuments.us/reader035/viewer/2022081511/56649cb65503460f9497a72c/html5/thumbnails/8.jpg)
Implantation outside the uterus
Implantation inside Fallopian tube
called tubal pregnancy
1 in 50 pregnancies is
ectopic

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

Menstrual CycleDays 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

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

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.

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
![Page 23: Chapter 16 Lessons 2 & 3 -Female Reproductive System -Male Reproductive System](https://reader035.vdocuments.us/reader035/viewer/2022081511/56649cb65503460f9497a72c/html5/thumbnails/23.jpg)
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
![Page 24: Chapter 16 Lessons 2 & 3 -Female Reproductive System -Male Reproductive System](https://reader035.vdocuments.us/reader035/viewer/2022081511/56649cb65503460f9497a72c/html5/thumbnails/24.jpg)
Male Reproduction System
• Do Now:• List Secondary Sex Characteristics (changes that
happen to the body during puberty) for either males or females.
![Page 25: Chapter 16 Lessons 2 & 3 -Female Reproductive System -Male Reproductive System](https://reader035.vdocuments.us/reader035/viewer/2022081511/56649cb65503460f9497a72c/html5/thumbnails/25.jpg)
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 bonesHair growth Increase in height Deepening of voice Rougher tougher skin
![Page 26: Chapter 16 Lessons 2 & 3 -Female Reproductive System -Male Reproductive System](https://reader035.vdocuments.us/reader035/viewer/2022081511/56649cb65503460f9497a72c/html5/thumbnails/26.jpg)
Male Reproductive Organs
External Organs
• Penis • Scrotum – external skin sac
- Hangs from the body hold testicles- Temperature regulation
![Page 27: Chapter 16 Lessons 2 & 3 -Female Reproductive System -Male Reproductive System](https://reader035.vdocuments.us/reader035/viewer/2022081511/56649cb65503460f9497a72c/html5/thumbnails/27.jpg)
Male Reproductive SystemInternal Organs
• Testes – 2 small glands (seminiferous tubules)- sperm production- testosterone (hormone)
• Epididymis- sperm mature and are stored
![Page 28: Chapter 16 Lessons 2 & 3 -Female Reproductive System -Male Reproductive System](https://reader035.vdocuments.us/reader035/viewer/2022081511/56649cb65503460f9497a72c/html5/thumbnails/28.jpg)
• Vas Deferens- tubes that extend from each epididymis to the urethra
• Seminal Vesicle-first stop fluid
![Page 29: Chapter 16 Lessons 2 & 3 -Female Reproductive System -Male Reproductive System](https://reader035.vdocuments.us/reader035/viewer/2022081511/56649cb65503460f9497a72c/html5/thumbnails/29.jpg)
• 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
![Page 30: Chapter 16 Lessons 2 & 3 -Female Reproductive System -Male Reproductive System](https://reader035.vdocuments.us/reader035/viewer/2022081511/56649cb65503460f9497a72c/html5/thumbnails/30.jpg)
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
![Page 31: Chapter 16 Lessons 2 & 3 -Female Reproductive System -Male Reproductive System](https://reader035.vdocuments.us/reader035/viewer/2022081511/56649cb65503460f9497a72c/html5/thumbnails/31.jpg)
Problems Male Reproductive System
• Hernia – intestine pushes through abdominal wall- lifting heavy object- lump in groin area & pain
• Testicular cancer – ages 14-40 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
