Résumé
Powerful assisted reproductive techniques (ART) have been developed to treat infertility. Intrauterine insemination (IUI) and in vitro fertilization (IVF) have been employed widely and allowed many couples the reward of children. With the improved ability to manipulate gametes precisely and routinely, intracytoplasmic sperm injection (ICSI) became possible and today represents one of the greatest technological advances in our capacity to treat various forms of infertility due to severe sperm defects. This highly technical treatment, however, is still not available in all ART centers and has been suggested to have a major drawback in that it bypasses the roocyte’s natural barriers that might discriminate spermatozoa before fertilization.
