When we talk about in vitro fertilization we are referring to fertility that is taking place outside of the body at least partially, two of the main reasons why doctors use in vitro fertilization is because the woman's tubes may be blocked or the man may have a very low sperm count. IVF involves the collection and harvesting of eggs which are mature enough to be fertilized by sperm that has been collected.
The first step is called induction, this involves the stimulation of the eggs in the ovary so that they ripen, it is done to take out multiple eggs as some them may not have been fertilized. A close watch is kept on the eggs to ensure that hormone levels are maintained, this is done through the use of ultrasounds and blood tests.
An ultrasound may be utilized to help guide a needle through the pelvic cavity in order to take out the eggs. This is the second stage, the patient will then be put under local anesthesia to make retrieving the eggs as painless as possible. This removal of eggs is reffered to as follicular aspiration. Some women may experience cramping once the eggs have been removed from the ovaries.
For some women they are lucky and the pressure goes away in a day or two but for other women this is not the case and they will feel this pressure for weeks after the retrieval has been completed. In the third stage the male partner is asked to give a sample of sperm this is obtained from his ejaculate. The fourth step involves the actual insemination, sperm and egg are placed in incubators these provide the appropriate environment for fertilization to take place.
Sometimes if there is considerably less chance for fertilization, a single sperm maybe isolated and used in an attempt to achieve fertilization. Eggs are monitored constantly to ensure that cells are dividing and that fertilization is occurring. As soon as they are fertilized the eggs are known as embryos.
In the fifth stage the embryo is put in the uterus. This occurs one to seven days later. The embryo has now divided into two and four cells. A speculum is inserted into the woman's vagina in order for the catheter to pass into the uterus, once inside the catheter is used to insert a number embryos into the woman's womb. This usually a pain free process although there are a few women that report some discomfort. An ultrasound and blood tests are done some time later to find out if conception has taken place.
