The Patient's Guide to Embryology

The basics of every IVF cycle are the same:

  1. Ovarian hyperstimulation – hormone drugs are used to control the ovaries, stimulating them to produce multiple eggs simultaneously.
  2. Collect the eggs and prepare the sperm – once the eggs are at the correct stage of maturity they are collected from the ovaries in a simple procedure where a needle is inserted through the wall of the vagina. A semen sample is prepared at the same time to isolate the best sperm for fertilization.
  3. Fertilization – the eggs are inseminated using either traditional IVF or ICSI.
  4. Embryo culture – the embryos are grown in an incubator for up to 6 days.
  5. Embryo transfer and freezing – the best quality embryo is transferred and any surplus good quality embryos are frozen for later use.

To make things even trickier, IVF is a fast-paced industry where new developments emerge rapidly and techniques are constantly changing. An IVF cycle that is optimally planned can maximise your chance of success and small changes can be the difference between success and failure. So what kind of treatments are right for you?
