OBJECTIVE: To determine the effect of short-term combined oral contraceptive (OCP) use on antral follicle count (AFC) in obese and nonobese women with infertility. STUDY DESIGN: A retrospective review of women who had an AFC (sum of 2– 10 mm bilateral ovarian follicles on basal follicular phase ultrasound) measured before and after short-term OCP use between the years 2005 and 2010. These were women who had a baseline AFC measurement during an unsuccessful controlled ovarian hyperstimulation/intrauterine insemination who were then placed on OCPs prior to an in vitro fertilization (IVF) cycle that included a subsequent AFC measurement at baseline. RESULTS: A total of 57 IVF cycles met criteria for inclusion in the study. AFC was not impacted by OCP use in the nonobese cohort (BMI <30). Baseline AFC in obese women (BMI ≥ 30), however, increased after OCP use (18±6 vs. 28±9, p=0.002). CONCLUSION: Use of suppressive medications like OCPs in obese women increases AFC during IVF, potentially by AFC cohort synchrony. This observation warrants consideration when using AFC to predict gonadotropin/ART response as well as future prospective research to further elucidate potential etiologies.
