In Vitro fertilization is the proper medical name for what the press dubbed ?test tube babies? many years ago. The woman?s eggs are taken from her ovaries and then in a laboratory dish, fertilized with sperm before being inserted into her womb. In Vitro Fertilization is recommended if you are an older woman, have been diagnosed with unexplained infertility, those whose tubes are blocked, or if other techniques have been unsuccessful.

Methods of IVF will invariably differ a little from clinic to clinic but should proceed along these lines. At the start of your treatment your doctor gives you drugs to block the hormones your pituitary gland usually produces during your monthly cycle. The reason for this is so the physician has improved control over when your eggs are produced. You then take different drugs to make your ovaries produce more than one egg.

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. Once the time is right, another hormone will be injected 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. Eggs are usually collected by ultrasound guidance which takes around 30 minutes and you are either given a drug to make you drowsy or a general anesthetic.

It is not until this time that the man gets involved and needs to produce a sample of fresh sperm. This will be stored for a short time before the sperm are washed and spun at a high speed, so that the healthiest and most active can be selected. 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. Successfully fertilized embryos are then left for a further day to two days before the last inspection is carried out.

Once your eggs have been collected there is a waiting period of two days, then you are given pessaries, an injection or gel to ready the lining of your womb.
