In Vitro Fertilization literally means ‘fertilization in glass’, hence the familiar name of ‘test tube baby’. Essentially, a woman’s eggs are removed from her ovaries and sperm from her partner or donor is used to fertilize them before being inserted into her womb. Many older women use In Vitro Fertilization as it is a recommended procedure for them, also if there is a blockage in the tubes, unexplained infertility or if other methods have failed.

Although techniques for In Vitro Fertilization vary, a normal method of IVF would go something like this. Initially your physician will give you hormone blocking drugs normally produced during your menstrual period. This allows them better control over when your eggs are produced. Further drugs are given to ensure your ovaries create more than a single egg.

Estrogen levels produced by the eggs are monitored to ensure they rise, using vaginal ultrasound scans and blood tests. Once the time is right, another hormone will be injected to help the eggs mature. This injection is given 34 to 38 hours before the eggs will be collected to the timing of this is very important. To collect the eggs, ultrasound guidance is used and as it takes about half an hour, either drugs or a general anesthetic is given which may make you feel drowsy.

Next the man must produce some fresh sperm at about the same time as the eggs are collected. The health of the sperm is important so after a short storage period they are spun at high speed after being washed so only the healthiest and most active are used. If you are using donated sperm, the sample is taken from the freezer and prepared in the same way. The process then continues with the eggs and sperm left for 16 to 20 hours in a laboratory dish to mix and after that period, checked to see if they have fertilized. Successfully fertilized embryos are then left for a further day to two days before the last inspection is carried out.

To ensure the womb is ready for the fertilized egg, two days after they have been collected, the womb lining is prepared by giving you pessaries, gel or an injection.
