Chapter 16 Lessons 2 & 3
-Female Reproductive System
-Male Reproductive System
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%
Uterus- pear shaped- egg implants in uterine lining
- fetus grows
Endometrium – lining of uterus
Cervix- opening uterus to vagina
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.
455
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
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
Male Reproduction System
• Do Now:• List Secondary Sex Characteristics (changes that
happen to the body during puberty) for either males or females.
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
Male Reproductive Organs
External Organs
• Penis • Scrotum – external skin sac
- Hangs from the body hold testicles- Temperature regulation
Male Reproductive SystemInternal Organs
• Testes – 2 small glands (seminiferous tubules)- sperm production- testosterone (hormone)
• Epididymis- sperm mature and are stored
• Vas Deferens- tubes that extend from each epididymis to the urethra
• Seminal Vesicle-first stop fluid
• 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
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
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
