HERNANDEZ LEAL, Cecilia. Intracytoplasmic sperm injection (ICSI): an assisted reproduction technology with indications. Rev Colomb Obstet Ginecol [online]. 2003, vol.54, n.3, pp.157-163. ISSN 0034-7434.

The intracytoplasmic sperm injection (ICSI) from its introduction in humans has let to treat severe male infertility with great results. However, the diffusion of this technology has led to its application in several cases without a clear indication, displacing in many cases the in vitro fertilization (FIV), without enough reasons. This review looks for calling the attention in the physiology of fertilization, recalls the events involved in ICSI which transgress the principles of this physiology and are great enigmas about future development implications. The different findings described by the basic research groups in this area, if they do not give a relation between the ICSI technology and any undesirable effect, they leave the investigation open and let us conclude that ICSI is an assisted reproductive technology with clear indications and should not be used so widely.

Palabras clave : ICSI; assisted reproductive technologies; fertilization.
