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. Women who use In Vitro Fertilization are often recommended this method when others have failed or because they are older.
Methods of IVF will invariably differ a little from clinic to clinic but should proceed along these lines. 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 to assist control over when the eggs are ready. After this your ovaries are stimulated by drugs to create more than one egg.

To monitor your developing eggs, vaginal ultrasound scans are taken as well as blood tests to ensure that the eggs are increasing the estrogen level. Another hormone injection will be given when the tests show the time is right to help the 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. 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. Your eggs are then mixed with your partner?s sperm and left in a laboratory dish for 16-20 hours before they are checked to see if any have fertilized. Any that haven?t, or any that have fertilized abnormally, are discarded and the remaining embryos are then left for another 24-48 hours before being checked again.
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.
