Introducton: This paper analyzes cycles of ovarian stmulaton followed by intrauterine inseminaton or tmed intercourse that resulted in pregnancy. Our objectve was to identfy characteristcs of the patent or ovarian response that are associated with multple pregnancy. Material and methods: We performed a descriptve retrospectve observatonal study of 261 cycles where pregnancy was achieved by intrauterine inseminaton or tmed intercourse. The sample was obtained from 1,189 infertle couples treated from January 2009 to December 2014. We evaluated features that were potentally associated with multple pregnancy and dependent on the patent, treatment, and ovarian response. Results: Of all the pregnancies analyzed, 88.9% were singleton and 11.1% multple (8.4% twins, 2.7% triplet). In the multple pregnancy group, the average number of intermediate follicles (14-16 mm), follicles measuring ? 17 mm, and the total number of follicles on the day human chorionic gonadotropin was administered were higher than for the singleton pregnancy group (p < 0.05). We found no correlaton between multple pregnancy and age, type and diagnosis of infertlity, drug used for stmulaton, inital and total dose of gonadotropin, number of treatment cycles, and motle sperm count. Conclusions: This study confrms the associaton between multple births and increased number of follicles. When follicles were classifed by size and multple pregnancy as twin and triplet, we found that intermediate follicles were signifcantly associated with twin pregnancy. Consequently, they must be taken into account when deciding to cancel a cycle in order to try to reduce the risk of multple pregnancy
