Background: A common question among health care professionals is how to manage nonvisible strings in users of intrauterine contraceptives (IUCs) at repeat follow-up visits. This study assessed the position of the IUCs in women who consulted repeatedly with nonvisible IUC strings.
Study Design: The medical records of the clinic were reviewed to identify new acceptors and switchers who had an IUC inserted between 1990 and 2009.
Background: The aim of this study was to evaluate bone mineral density (BMD) at baseline and at 18 and 36 months of use of etonogestrel (ENG)-and levonorgestrel (LNG)-releasing contraceptive implants. This is a continuation of a previous study in which BMD was evaluated at baseline and at 18 months of use.
Methods: A total of 111 women, 19-43 years of age, were randomly allocated to use one of the two implants.
Background: The aim of the study was to compare bone mineral density (BMD) before insertion and at 18 months of use of etonorgestrel- and levonorgestrel-releasing contraceptive implants.
Methods: One hundred and eleven women, 19-43 years of age, were randomly allocated to two groups: 56 to etonorgestrel and 55 to levonorgestrel. BMD was evaluated at the midshaft of the ulna and at the distal radius of the non-dominant forearm using dual-energy X-ray absorptiometry before insertion and at 18 months of use.
Objective: To evaluate the prevalence of enlarged ovarian follicles among users of a 20 micrograms/d levonorgestrel-releasing intrauterine system (Mirena, Leiras Oy, Turku, Finland), of subdermal contraceptive implants releasing Nestorone (Population Council, New York, New York) and of the TCu 380A intrauterine device.
Study Design: A cohort study was conducted at the Universidade Estadual de Campinas, Brazil. Three hundred women were enrolled, with 100 participants in each group.
