Reducing infertiltiy

• What are contraceptives used for?

  Preventing pregnancy
• What hormones can be taken to reduce fertility?

  Oestrogen and Progesterone
• Oestrogen:

  • Used to prevent egg release
  • If oestrogen is taken every day to keep the level of it permanently high, it inhibits FSH production
  • Means that after a while, egg maturation and therefore egg release stop and stay stopped
• Progesterone

  • Reduces fertility by stimulating the production of thick cervical mucus which prevents any sperm getting through and reaching an egg
  • Can inhibit egg maturation and therefore the release of an egg too
