The term in vitro fertilization refers to the union of the egg and sperm (fertilization) occurring in the laboratory. This can be done in two ways: conventional IVF or IVF-ICSI.
Both assisted reproduction techniques are the same in terms of treatment, medication, and the process that the patient must follow. In this sense, there are no advantages or disadvantages to undergoing conventional IVF or ICSI.
The difference between these two IVF methods lies in how fertilization occurs, that is, in the way the egg and sperm are joined.
On the one hand, conventional IVF is less invasive than ICSI, as the sperm themselves have to enter the egg on their own. This brings us closer to the biological process, allowing the natural selection of those sperm with the greatest reproductive potential and, therefore, with the greatest chance of producing a viable embryo capable of developing into a healthy child.
On the other hand, in ICSI, it is the embryologist who is responsible for introducing the sperm into the egg with the help of a microinjector.
