Using hormones to treat infertility

I can describe the use of hormones to treat some types of infertility in humans.

Lesson details

Key learning points

  1. Infertility is the inability to become pregnant (conceive).
  2. In adult human females, some types of infertility are caused by problems with hormones that control the menstrual cycle.
  3. Hormones can be used as a treatment for these types of infertility.
  4. The use of hormones in IVF treatment.

Common misconception

IVF is highly effective without side effects. People can already choose the features of a baby. All people can have IVF from the NHS.

IVF is less than 40% effective and this decreases with the age of the mother over 35. Genetic testing of embryos can be used to look for a disease, but genes cannot be altered. There is criteria for receiving IVF from the NHS and it is limited.

Keywords

  • Infertility - The inability to become pregnant (conceive).

  • Menstrual cycle - A monthly cycle which involves the maturation and release of an egg, and menstruation.

  • IVF - In vitro fertilisation, in which an embryo is formed in a laboratory and then inserted into the uterus of the mother.

  • FSH - Follicle stimulating hormone, which matures follicles containing eggs in the ovaries.

  • Embryo - A development stage when a fertilised egg starts to divide.

Pupils may wish to do the final task as a role play conversation; or the class could do further research and then debate it.
