Expression of Concern

Badawy, et al., “Extended letrozole therapy for ovulation induction in clomiphene-resistant women with polycystic ovary syndrome: a novel protocol” (Fertil Steril 2009;92:236–9). Concern has been raised about the article listed above. The ASRM publications committee has investigated the data presented in the study, and though separated in time and reported for different groups of study subjects, the data are identical for many of the variables in another manuscript (PMID: 18314112). While a considerable time has elapsed since the publication of this manuscript, the similarities in data pertaining to dif ferent study groups could not be explained.
