What you need to know

  • Hormones that control the menstrual cycle can be given so that an egg matures and is released.
  • LH is the hormone that triggers ovulation of a mature egg.
  • In IVF, eggs are collected and fertilised by sperm in the laboratory, outside the body.
  • Once the embryos are tiny balls of cells, they are placed in the uterus.
  • Success rates are limited, the process is emotionally stressful, and there are further drawbacks to weigh up.
