RESUMO

The objective of this study were to evaluate the prevalence of functional ovarian cysts in users of two contraceptive implants compared to users of intrauterine device (IUD) during the first year of use. A total of 344 women were enrolled at 3 months of use of the etonogestrel-releasing implant (Implanonâ), the levonorgestrel-releasing implant (Jadelleâ), or the TCu380A IUD. Bimanual pelvic examination and vaginal ultrasound were performed during routine 3, 6 and 12-month visits of asymptomatic women. Women with functional ovarian cysts (or enlarged ovarian follicles >25mm), were assessed weekly until disappearence or reduction of the image (including estradiol (E2) and progesterone measurement) and women with no ovarian enlargement underwent the same evaluation for the same period of time. Functional ovarian cysts were detected in 5.1%, 13.0%, and 1.9% of users of Implanon®, Jadelle®, and IUD, respectively, at 3 months. At the 6th month of use, prevalence was 7.1%, 7.8%, and 1.1%, whereas at 12 months rates were 257%, 14.7%, and 1.2% in the 3 groups, respectively. E2 levels were significantly. higher among users with ovarian cysts than controls. The time until disappearance of the ovarian cyst was similar in all 3 groups. There were more cases of menorrhagia in users of implants who had ovarian cysts than in those with no ovarian enlargement. The finding of functional ovarian cysts or enlarged ovarian follicles during the first year of use of Implanon® and Jadelle® implants is common and transient and should not be interpreted as a pathologic ovarian cyst. No further medical interventions are necessary
