In Vitro fertilization is the proper medical name for what the press dubbed ?test tube babies? many years ago. Eggs are fertilized in a laboratory dish with sperm and then place inside the woman?s 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.

Whilst every clinic works slightly differently, the main procedure is a fairly routine one. At first your physician will halt the release of hormones that are produced during your monthly cycle by giving you some drugs. The reason for this is so the physician has improved control over when your eggs are produced. To ensure you ovaries produce more than a single egg, further drugs are given.

Vaginal ultrasound scans are carried out to monitor your developing eggs along with blood tests to chart the rising levels of estrogen produced by the eggs. As soon as the tests show that the time is right, you will have another injection of a different hormone to help your eggs mature. The timing for this injection is crucial and must be carried out no earlier that 34 or later than 38 hours before your eggs are collected. Ultrasound guidance is used to help collect the egg but it means you have to be given drugs or a general anesthetic to help you relax because it takes about 30 minutes.

It is not until this time that the man gets involved and needs to produce a sample of fresh sperm. To make sure that the best sperm are used for the process, the sample is washed and then spun at high speed, this will give the healthiest and the most active sperm. Donated sperm is kept in the freezer but the same method to prepare it is used. After the eggs and sperm have been collected they are left to mix in a laboratory dish for between 16 and 20 hours and then inspected to see whether fertilization has taken place. 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.
