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. 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.

Although techniques for In Vitro Fertilization vary, a normal method of IVF would go something like this. At first your physician will halt the release of hormones that are produced during your monthly cycle by giving you some drugs. Blocking the hormones helps the doctor have greater control over your egg production. Once this has been done further drugs are given to multiply the number of eggs your ovaries produce.

Estrogen levels produced by the eggs are monitored to ensure they rise, using vaginal ultrasound scans and blood tests. 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. To collect the eggs, ultrasound guidance is used and as it takes about half an hour, either drugs or a general anesthetic is given which may make you feel drowsy.

It’s about this time that the man must produce some fresh sperm. Once this has been done the sperm are stored for a short period before they are washed and then spun at high speed to ensure only the healthiest ad most active sperm are used. Sperm which has been donated is kept in a freezer but the same method for preparation is used. The process can take between 16 and 20 hours during which time the sperm and eggs are allowed to mix in a laboratory dish before they are inspected to find out if the fertilization was successful. Only those embryos that have fertilized successfully are kept and left for a further day to two days before a final inspection.

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.
