<ul><li> Slide 1 </li> <li> Slide 2 </li> <li> Produced by endocrine glands Male endocrine glands = Testes Female endocrine glands = Ovaries </li> <li> Slide 3 </li> <li> What happens when a male or female goes through puberty? Why? </li> <li> Slide 4 </li> <li> 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 &amp; production of estrogen </li> <li> Slide 5 </li> <li> Estrogen &amp; Progesterone produced by ovaries LH &amp; 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!! </li> <li> Slide 6 </li> <li> 1. The release of a mature egg from a follicle 2. The preparation of the uterus for pregnancy </li> <li> Slide 7 </li> <li> Begins a puberty Ends at menopause Normal (average) cycle is 28 days can vary greatly and is affected by illness, stress and other factors. </li> <li> Slide 8 </li> <li> Four stages: 1.Follicle stage 2.Ovulation 3.Corpus leutem stage 4.Menstruation </li> <li> Slide 9 </li> <li> 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 </li> <li> Slide 10 </li> <li> Four stages: 2.Ovulation Mature egg released from follicle. FSH inhibited by estrogen -&gt; stimulates release of LH This happens around/on day 14. </li> <li> Slide 11 </li> <li> Four stages: 3.Corpus luteum stage 10-12 days in length Burst follicle develops into corpus luteum -&gt; produces progesterone Progesterone stimulates further thickening of uterine lining. </li> <li> Slide 12 </li> <li> Four stages: 4.Menstruation occurs if no egg is fertilized. Progesterone secretion decreases Uterine lining degenerates Tissue/blood are discharged from body </li> <li> Slide 13 </li> <li> Estrogen Progesterone </li> <li> Slide 14 </li> <li> FSH LH </li> <li> Slide 15 </li> <li> Slide 16 </li> </ul>
