Are there any advantages or disadvantages to ICSI treatment compared to normal IVF?

The conventional IVF and ICSI processes are the same in terms of the treatment, medication and process that the patient must follow. In this sense, there are no advantages or disadvantages to doing one or the other method.

The only difference takes place in the laboratory in the way in which the egg and sperm are joined (fertilization). Conventional IVF is less invasive than ICSI, as it is the sperm themselves that have to enter the egg by their own means. 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 possibility of giving rise to a viable embryo capable of developing into a healthy child.

In ICSI, for its part, a spermatozoid is introduced into the ovum in a forced way by means of microinjection. This makes the fertilization rate higher than in the case of conventional IVF.
