Most people know the term ?test tube baby? but the correct name for this process is ?In Vitro fertilization?. Eggs are fertilized in a laboratory dish with sperm and then place inside the woman?s womb. Women who use In Vitro Fertilization are often recommended this method when others have failed or because they are older.

The In Vitro Fertilization process should go something like the method set out below but may differ slightly between clinics. Initially your physician will give you hormone blocking drugs normally produced during your menstrual period. 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. To help the eggs mature a different hormone will be injected once all the tests say the time is right. 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. 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.

It?s about this time that the man must produce some 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. 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. Any embryo?s that have fertilized abnormally or not at all, are discarded, then those remaining are left for another 24 to 48 hours prior to a final check.

In order to help prepare your womb, pessaries, gel or an injection are given two days after your eggs have been collected.
