Fertility drugs and ovarian cancer

Recent case reports of ovarian cancer associated with infertility treatment raise the question of a possible etiopathogenetic role of fertility drugs in ovarian cancer. In this paper, the possible relationship between infertility treatment and ovarian cancer is reviewed with respect to the epidemiological and pathogenetic profiles of ovarian cancer and the potential risk factors associated with fertility drugs; a case report review and a critical reappraisal are also provided within this article. Currently available data in the literature, from epidemiological studies and case reports, suggest that a direct causal effect of infertility treatment on ovarian cancer seems unlikely. Since infertile women are likely to have a higher risk for the development of ovarian cancer, and the role of fertility drugs in the etiopathogenesis of ovarian carcinoma is not established, a close clinical examination of infertile patients before, during and after infertility treatment is recommended. Moreover, further investigation is required to resolve the question of the possible association between fertility drugs and ovarian cancer through large prospective epidemiological or retrospective case-control studies
