To determine the frequency of dose adjustments made in subsequent CC cycles. Design: A retrospective evaluation of 5800 CC with IUI cycles between 2001-2008. Materials and Methods: Patients undergoing CC with intrauterine insemination (IUI) were analyzed by CC dose and ongoing pregnancy. Dose adjustments between cycles were analyzed. Chi Square analysis was performed. Results: The ongoing pregnancy rate (PR) with all doses of CC was 12.3%. The rate of twins and triplets was 7.9% and 0.4% with no differences between CC doses, p=0.68. The dose of CC was altered in subsequent cycles primarily determined by ovarian response observed on ultrasound. The selected dose of CC100 was adjusted significantly less frequently than other clomid doses, p
