Reproductive Hormones (Mammals)

 

Lesson Topic Statement(s) and Objective(s) Activities
1 Male system

6.6.S1:  Annotate diagrams of the male and female reproductive system to show names of structures and their functions.

  • Label a diagram of the male reproductive system, including the bladder, sperm duct, penis (with foreskin and erectile tissue), urethra, testis, scrotum, epididymis, prostate gland and seminal vesicle.

  • Outline the function of the following male reproductive structures:  testis, scrotum, epididymis, sperm duct, seminal vesicle, prostate gland, urethra and penis.


6.6.U6:  Testosterone causes prenatal development of male genitalia and both sperm production and development of male secondary sexual characteristics during puberty.

  • Outline role of testosterone in prenatal development of male genitalia.

  • State testosterone's role in stimulating the primary sexual characteristic of males.

  • List secondary sexual characteristics triggered by testosterone at puberty.

2 Female system

6.6.S1:  Annotate diagrams of the male and female reproductive system to show names of structures and their functions.

  • Label a diagram of the female reproductive system, including the ovary, uterus, bladder, urethra, vulva, vagina, cervix and oviduct.

  • Outline the function of the following female reproductive structures: ovary, oviduct, uterus, cervix, vagina, and vulva.


6.6.U7:  Estrogen and progesterone cause prenatal development of female reproductive organs and female secondary sexual characteristics during puberty.

  • State the sources of estrogen and progesterone used in embryonic development.

  • Describe prenatal development of female reproductive organs.

  • List secondary sexual characteristics triggered by estrogen and progesterone at puberty.

3 Menstrual cycle

6.6.U8:  The menstrual cycle is controlled by negative and positive feedback mechanisms involving ovarian and pituitary hormones.

  • Outline events occurring during the follicular and luteal phases of the menstrual cycle.

  • State the source and location of action of hormones in the menstrual cycle, including FSH (follicle stimulating hormone), LH (luteinising hormone), estrogen and progesterone.

  • Outline the role of hormones in the menstrual cycle, including FSH (follicle stimulating hormone), LH (luteinising hormone), estrogen and progesterone.

  • Describe the negative feedback loops that regulates secretion of FSH.

  • Describe the positive feedback loop that regulates secretion of estrogen.

  • Annotate a graph showing hormone levels in the menstrual cycle, illustrating the relationship between changes in hormone levels and follicular development, ovulation, changes to the corpus luteum, menstruation and the thickening of the endometrium

4 IVF

6.6.A4:  The use of IVF of drugs to suspend the normal secretion of hormones, followed by the use of artificial doses of hormones to induce superovulation and establish a pregnancy.

  • Define in vitro fertilization.

  • Outline the process of in vitro fertilization including down-regulation, superovulation, harvesting, fertilization and implantation.

5 Effect of pollution

11.4.NOS:  Assessing risks and benefits associated with scientific research:  the risks to human male fertility were not adequately assessed before steroids related to progesterone and estrogen were released into the environment as a result of the use of the female contraceptive pill.

  • Outline how the female contraceptive pill prevents pregnancy.

  • Describe problems attributed to estrogen pollution in water.
