Failed IVF Cycle

Test tube babies, as they are commonly known, are created using IVF or In Vitro Fertilization which literally means fertilization in glass. The woman?s eggs are taken from her ovaries and then in a laboratory dish, fertilized with sperm 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.
Methods of IVF will invariably differ a little from clinic to clinic but should proceed along these lines. Your doctor will give some drugs to block the hormones normally released during the menstrual cycle. Blocking the hormones helps the doctor have greater control over your egg production. Further drugs are given to ensure your ovaries create more than a single egg.

Blood Tests and vaginal ultrasound scans are used to monitor the estrogen level 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 reason for this is that the eggs will be collected between 34 and 38 hours later, even if it is the middle of the night. Collecting the eggs takes about 30 minutes and is carried out using ultrasound guidance so often either drugs or a general anesthetic is given to make you feel more relaxed.
Next the man must produce some fresh sperm at about the same time as the eggs are collected. 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. Sperm which has been donated is kept in a freezer but the same method for preparation is used. Once that has been completed the sperm is mixed with the eggs in a dish and left for between 16 to 20 hours and then checked to see if they have been 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.
The womb needs to be ready to accept the fertilized egg so a gel, injection or pessaries are given to ensure the lining of the womb is prepared.
