摘要：This study are describe the diverse genetic causes of masculine infertility, the cromossomic and molecular alteration that may happen in patients with oligo or azoospermia. Its also pretends to revise the tecniques of pre-implantational diagnosis avaliable nowadays. The study is centered in genetic aspects of the masculine factor in the couples infertility. The importance of this study is in the ethic duty of analysing case by case, when to opt for intra-citoplasmatic injection of spermatozoons (ICIS), it because a significative fraction of person with idiopatic oligo or azoospermia have genetic alterations in their spermatozoons or spermatogonias, and there is a great probability of the child to have a genetic disease. This way, the (ICIS) is not a good way to the coupler wich face this problem.
