¿What is In Vitro fertilization and what types are


In vitro fertilization is the medical process of stimulating ovulation in women doing that instead of producing an egg every month produce more, 8 or 10. That is achieved by medication to be administered daily. When that woman follicles, where the eggs are, they are adequately sized, the extract in operating room under sedation. Then, in the laboratory, these ova are incubated and placed with the man's sperm to produce embryos. There are 2 big different processes, one is conventional in vitro fertilization based on putting sperm with the eggs and that they penetrate into the egg, a process that has been making for over 30 years. Then there is what is called intracytoplasmic sperm injection, or ICSI on selecting a sperm and put it in the egg. This second process is newer, it is made from about 18 years ago, and allows better targeting of sperm. Currently there is a superior version of which is called ICSI IMSI which involves injecting the morphologically selected sperm increases to 8000, allowing us to select the best sperm. Do not forget that the better the sperm into the egg say we better odds of having a good and the better embryo embryos will be the greater the chance of pregnancy. Therefore it is also important in addition to study and treat women, make proper study and treatment of man as there is a significant weight of the man inside the chances of success of in vitro fertilization.

¿Anyone can use this technique


If any woman actually produce ovules. While it is true that the younger women there will be a greater number of ovules and better and the more advanced the age of the woman there will be a smaller number of ovules and lower quality. Having a smaller number of ovules are worse embryos, fewer embryos and lower rates of gestation. It is necessary to seek medical advice before 38-40 years because from that age it seriously compromises the possibility of pregnancy with their own eggs and probably the only way to achieve success that has come to be the technique of egg donation.

¿Ensures pregnancy


No, safety is never achieved pregnancy. The chances of pregnancy ranging from 70% in women of about 30 years to 15%, more or less, in women of 42 years, always with their own ovules. With donor eggs can reach 70-80% but never ensures 100 % pregnant.

¿What are the key points of In Vitro fertilization


Probably the most important are the age of the woman, the higher the chances of pregnancy age unless there. Then the correct study is essential both women and men as the proper study and treatment of both will allow us to achieve higher rates of gestation. And finally say that today we have a very advanced technology that has enabled us to achieve high pregnancy rates, in fact millions of children worldwide have been born with these techniques in vitro fertilization and artificial insemination.
