What are the different forms of contraception?
Remember to check for PROGRESS
Focus on Knowledge, Skills and Understanding
Success Criteria: You will show your learning by...
  1. Students should be able to evaluate the different hormonal and non- hormonal methods of contraception.
  2. Fertility can be controlled by a variety of hormonal and non-hormonal methods of contraception.
  3. These include: ? oral contraceptives that contain hormones to inhibit FSH production so that no eggs mature ? injection, implant or skin patch of slow release progesterone to inhibit the maturation and release of eggs for a number of months or years ? barrier methods such as condoms and diaphragms which prevent the sperm reaching an egg ? intrauterine devices which prevent the implantation of an embryo or release a hormone ? spermicidal agents which kill or disable sperm ? abstaining from intercourse when an egg may be in the oviduct ? surgical methods of male and female sterilisation. Explain everyday and technological applications of science; evaluate associated personal, social, economic and environmental implications; and make decisions based on the evaluation of evidence and arguments.
  4. (HT) Explain the use of hormones in modern reproductive technologies to treat infertility
  5. (HT) Explain how developments of microscopy techniques have enabled IVF treatments to develop.
  6. This includes giving FSH and LH in a ?fertility drug? to a woman. She may then become pregnant in the normal way. (HT only)
  7. Understand social and ethical issues associated with IVF treatments (HT only)
  8. Although fertility treatment gives a woman the chance to have a baby of her own: ? it is very emotionally and physically stressful ? the success rates are not high ? it can lead to multiple births which are a risk to both the babies and the mother. (HT only)
  9. Evaluate from the perspective of patients and doctors the methods of treating infertility. (HT only)

Keywords:
  • Controlled by physical blocks that stop sperm from entering the female system. (1)
  • Barrier contraception (1)
  • Hormonal contraception: Controlled by chemicals that travel through the bloodstream. (1)
  • Fertility: How likely someone is to produce viable offspring. (1)
  • Contraception: Methods of preventing pregnancy that are either chemical or physical. (1)

AFL/Key Questions:
  1. Give an advantage and disadvantage of condoms, the pill and the implant.
    Condoms - A - also protect against STIs - D - not quite as effective as some hormonal methods. Pill - A - Highly effective if used correctly - D - needs to be remembered to be taken. Implant - A - doesn't need to be remembered each day - D - Sometimes long-term protection is not suitable.
  2. What are the two categories of contraception?
    Hormonal and non-hormonal/barrier methods.
  3. Name at least 7 forms of contraception and how they work.
    These include: ? oral contraceptives that contain hormones to inhibit FSH production so that no eggs mature ? injection, implant or skin patch of slow release progesterone to inhibit the maturation and release of eggs for a number of months or years ? barrier methods such as condoms and diaphragms which prevent the sperm reaching an egg ? intrauterine devices which prevent the implantation of an embryo or release a hormone ? spermicidal agents which kill or disable sperm ? abstaining from intercourse when an egg may be in the oviduct ? surgical methods of male and female sterilisation.
  4. (HT) Which hormones can be used to treat infertility and how is it used?
    (HT) FSH - promotes the maturation of more eggs. These multiple eggs can increase the chance of conceiving or be used in IVF. LH - to cause the release of those mature eggs.
  5. (HT) How has developments in microscope technology and techniques enabled IVF treatment to improve?
    (HT) Microscopes can be used to monitor for fertilisation and development into embryos.
  6. (HT) Which hormones can be used to treat infertility and how is it used?Which hormones can be used to treat infertility and how is it used?
    (HT) FSH - promotes the maturation of more eggs. These multiple eggs can increase the chance of conceiving or be used in IVF. LH - to cause the release of those mature eggs.
  7. (HT) What are some social and ethical issues associated with IVF treatment?
    (HT) IVF costs the NHS money, increased number of babies being born, embryos that are not used may be destroyed. Some people consider embryos to be new lives and view their destruction as unethical. These could also be used for research.
  8. (HT) What are some of the disadvantages of IVF?
    (HT) Although fertility treatment gives a woman the chance to have a baby of her own: ? it is very emotionally and physically stressful ? the success rates are not high ? it can lead to multiple births which are a risk to both the babies and the mother
  9. (HT) Describe the stages of IVF.
    (HT) IVF involves giving a mother FSH and LH to stimulate the maturation of several eggs. The eggs are collected from the mother and fertilised by sperm from the father in a dish in the laboratory. The fertilised eggs develop into embryos. At the stage when they are tiny balls of cells one or two embryos are inserted into the mother's uterus (womb)
