In vitro fertilization (IVF) is an assisted reproduction technique whose main characteristic is that fertilization is performed outside the woman's body, in the laboratory. In this way, IVF makes it possible to help achieve pregnancy in cases in which the seminal quality is poor.
However, there are two ways of performing in vitro fertilization in the laboratory: conventional IVF and the IVF-ICSI technique, or simply ICSI.
Conventional IVF is performed when the quality of the male sperm is adequate, but in the case of severe male factor, ICSI is used. However, there are reproductive clinics that routinely perform the ICSI technique, leaving conventional IVF in the background.
