Among all of the methods of In Vitro Fertilization, the most widespread method is artificial insemination by the semen of the spouse or the donor and the method of extra corporal fertilization. This means that the process of fusion between the cells and the embryo takes place in the laboratory environment that is outside the women's body. Sometimes for such a procedure, the donor egg must be taken and used. The egg donation procedure is complex and takes hard work for many specialists, the perfect medical facilities, microscopic analysis.
The egg donation procedure begins with research and tests. If the woman decides to take the donor egg, it means that her body failed in producing her own oocytes. Selecting an egg donor that meets all the requirements of the couple is important too. The tests will provide a great deal of assistance. The donor must be in a generally good state of health, have a good evaluation cycle, and be free of venereal and infectious diseases. For the last decision in selecting the best suitable donor, he should estimate the responsibility for the woman recipient and her family. The donor should be a healthy young woman between the ages of 20 and 35. The families have the right to choose their own donor. It can be an anonymous donor or somebody of their relatives or acquaintances.
The next step of the egg donation procedure is the process of stimulating the donor's ovaries to produce multiple eggs. Typically, the woman's body may produce one or two eggs at the same time, but in order to increase the chances of recovering more healthy eggs, the donor should be given a number of hormonal injections. The eggs are growing, so special blood tests are needed to determine the hormonal reactions of the developing follicles and ultrasound observations are held. The egg removal is performed with the help of laparoscopic technology or with the aspiring needle under ultrasound control. A laparoscopy is performed by a light surgery in the abdomen under anesthetic.
After the eggs are retrieved, they are placed in a special liquid media and collected with the sperm for fertilizations. The conditions are closed to the natural environment that is provided by the fallopian tubes. The received embryos are transferred into the uterus of the woman recipient. It is usually not enough to become pregnant in one cycle that is why the remaining embryos are frozen for replacement later. The chance of becoming pregnant after the first cycle is approximately 20 percent, so repeated attempts should be made with the embryos.
There are many variations in the In Vitro Fertilization using egg donation procedure. For example, when the fertilization of the donor egg takes place in the recipient's body in her fallopian tubes. All of these methods depend on the physical opportunities of a woman and her peculiarities in every separate case. However, no method can give you a 100 percent guarantee that the embryos will develop normally. But, due to modern technologies and specialists, the risks are minimal.
