[The impact of infertility and its treatment on sexual life and marital relationships: review of the literature].

This paper reviews the literature on the psychosocial impact of infertility and its treatments by the ART on the marital sexuality, by paying special attention to the relationship between gender and the infertility experience. It is convenient to divide this literature into articles that explore the sexual life of the infertile couples on the one hand, and those focusing on the couple relationship - marital satisfaction and marital adjustment-, on the other hand. The literature on the infertile couples' sexuality and sexual satisfaction, mostly descriptive, presents infertility as a deleterious experience for both women and men even if the repercussion differ according to gender, with correlative dynamic effects within the couple. The contributions to the investigation of the couple relationship, mostly quantitative Anglo-Saxon studies, have produced equivocal or contradictory results concerning the satisfaction with the relationship, the closeness between the two partners so that it is difficult to assume a trend in this field. This situation is largely due to the problems of sampling. In this view, future research should perform its methodological apparatus to take into account the processual nature of the infertility experience, at both levels of couple history and its involvement in the ART process.
