  • Slide 1
  • Slide 2
  • Produced by endocrine glands Male endocrine glands = Testes Female endocrine glands = Ovaries
  • Slide 3
  • What happens when a male or female goes through puberty? Why?
  • Slide 4
  • Testosterone Secondary Sex Characteristics = Enable body to produce gametes Lower pitch voice Causes the testicles to descend Changes in body form Growth of beard/body hair Throughout the life of a man, his body will continue to produce testosterone, although the production rate will decline in old age. Females also produce testosterone Helps with osteoporosis & production of estrogen
  • Slide 5
  • Estrogen & Progesterone produced by ovaries LH & FSH produced by pituitary gland Luteinizing Hormone Follicle-Stimulating Hormone Functions = 1. Secondary Sex Characteristics = enable body to produce gametes Development of breasts Change in body form Growth of body hair 2. Enable body to prepare for pregnancy **Men also produce estrogen and progesterone!!
  • Slide 6
  • 1. The release of a mature egg from a follicle 2. The preparation of the uterus for pregnancy
  • Slide 7
  • Begins a puberty Ends at menopause Normal (average) cycle is 28 days can vary greatly and is affected by illness, stress and other factors.
  • Slide 8
  • Four stages: 1.Follicle stage 2.Ovulation 3.Corpus leutem stage 4.Menstruation
  • Slide 9
  • Four stages: 1.Follicle stage: FSH stimulates maturation of egg in follicle. Estrogen from follicle stimulates uterine lining to thicken. This takes 10-14 days to complete
  • Slide 10
  • Four stages: 2.Ovulation Mature egg released from follicle. FSH inhibited by estrogen -> stimulates release of LH This happens around/on day 14.
  • Slide 11
  • Four stages: 3.Corpus luteum stage 10-12 days in length Burst follicle develops into corpus luteum -> produces progesterone Progesterone stimulates further thickening of uterine lining.
  • Slide 12
  • Four stages: 4.Menstruation occurs if no egg is fertilized. Progesterone secretion decreases Uterine lining degenerates Tissue/blood are discharged from body
  • Slide 13
  • Estrogen Progesterone
  • Slide 14
  • FSH LH
  • Slide 15
