1. Male Reproductive System
Includes:
Scrotum – holds the testes outside the body
Keeps them 3o cooler to prevent death of sperm (maintains homeostasis)
Testes
Sperm and testosterone are produced here
Penis – allows for internal fertilization
Semen – contains the sperm

2. Female Reproductive System
Includes:
Ovary – contains the eggs (ova)
Production of eggs, estrogen and progesterone occurs here
1 egg is released each month during ovulation
Fallopian Tube – tube that leads from the ovary to the uterus
Fertilization occurs here (oviduct)
Uterus – development occurs here after fertilization (the center triangle)
Vagina – canal that leads from uterus to outside the body, sperm enters here, passageway for birth to occur

3. Menstruation Occurs if an egg is not fertilized
Results in a shedding of the uterine lining (wall)
Bleeding occurs to remove the tissue from the body
Average cycle is 28 days long
If fertilization occurs the menstrual cycle will temporarily stop for the duration of the pregnancy

4. Fertilization Combining of sperm and egg cells to form a zygote
23 unpaired chromosomes from male
23 unpaired chromosomes from female
Chromosomes join resulting in a fertilized egg (zygote) that has 46 paired chromosomes

5. Reproductive Hormones
Testosterone – Male
Enables sexual development and reproduction
Causes voice changes to occur
Helps with muscle development
Estrogen and Progesterone – Female
Sexual development and reproduction
Prepares the body for fertilization
Increases levels during pregnancy and decreases if fertilization does not occur (not pregnant)
