In Vitro Fertilization is a method of assisted reproduction in which the ovule-sperm junction is made outside the uterine tube, under laboratory conditions, resembling the natural conditions of the latter. The obtained embryos are transferred to the uterus, where they are implanted and developed.
Factors not susceptible to treatment with treatments of low complexity, or the repeated failure of these, benefit from in vitro fertilization (IVF) treatments, either conventional or through the intracytoplasmic injection of ICSI sperm.
