In Vitro Fertilization refers to fertilization that takes place outside of the body. IVF is used when a woman suffers from blocked tubes or a man has a very low sperm count. In summary, it involves the harvesting of mature eggs and the subsequent fertilization of those eggs with sperm that has been collected. There are several steps involved in In Vitro Fertilization. Each of them are discussed in further detail below.
The first stage involves what is known as induction, in this stage fertility drugs are utilized to stimulate the egg causing it to ripen. This process captures many eggs so that there will be enough for fertilization. Egg production and development is usually kept under strict watch through ultrasound monitoring of the ovaries and blood and urine tests that check hormone levels.
An ultrasound is also used to guide a needle through the woman's pelvic cavity in order to take eggs from the ovaries. Sedation and local anesthesia is usually employed to ensure that the retrieval process goes smoothly. This removal of eggs is known as follicular aspiration. A few women sometimes get cramps after the eggs are taken out of the ovaries. This feelings ceases after a few days, however some women have reported that they feel pressure in the area of their ovaries for several weeks after.
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.
