BACKGROUND Consecutive use of the levonorgestrel-releasing intrauterine system (LNG-IUS) is increasing. However, little is known about factors that predict the bleeding during consecutive use. The objective of this study was to analyse the possible factors which may predict the bleeding pattern during the first year of use of a second LNG-IUS. METHODS Fertile-aged women (n = 204) who had used...
BACKGROUND This study aims to explore the views of women concerning their choice of long-acting method of contraception. METHOD Two-hundred and eighty-six women who had either been sterilised or fitted with an etonorgestrel (ETN) implant or the levonorgestrel intrauterine system (LNG IUS) were invited to take part. A response rate of 54% was achieved. Women from all three groups reported posi...
BACKGROUND Previous studies have provided conflicting results regarding the effect of drospirenone-containing oral contraceptive pills (OCPs) on the risk of venous and arterial thrombosis. OBJECTIVES To conduct a systematic review to assess the risk of venous thromboembolism (VTE), myocardial infarction (MI), and stroke in individuals taking drospirenone-containing OCPs. SEARCH STRATEGY We ...
OBJECTIVE To assess ovarian suppression during oral contraceptive pill (OCP) use among normal-weight and obese women using two OCP doses. METHODS This was a prospective, double-blind, randomized trial of two 21-day monophasic OCP formulations (20-microgram ethinyl estradiol [E2],/100-microgram levonorgestrel compared with 30-microgram ethinyl E2/150-microgram levonorgestrel) among normal-weig...
PURPOSE To evaluate scheduled and unscheduled bleeding and spotting over 1 year of treatment with 91-day extended-regimen combined oral contraception (COC) providing continuous low-dose ethinyl estradiol (EE) in place of the traditional 7-day hormone-free interval (HFI). PATIENTS AND METHODS This post hoc analysis of a multicenter, open-label, 1-year, Phase 3 study of extended-regimen COC wit...
BACKGROUND Heavy menstrual bleeding is an important health problem. Two frequently used therapies are the levonorgestrel intra-uterine system (LNG-IUS) and endometrial ablation. The LNG-IUS can be applied easily by the general practitioner, which saves costs, but has considerable failure rates. As an alternative, endometrial ablation is also very effective, but this treatment has to be performe...
Implantable contraceptive is likely to be a promising new option for fertility control, as we have entered the twenty-first century and the world’s population grows by one billion people in a single decade. The main objective of this study was to develop a subdermal implant for levonorgestrol (a synthetic progestin from 19-norandrostanes) using a high molecular weight biodegradable polymer , i....
Women and couples continue to experience unintended pregnancies at high rates. In the US, 45% of all pregnancies are either mistimed or unwanted. Mishaps with contraceptives, such as condom breakage, missed pills, incorrect timing of patch or vaginal ring application, contraceptive nonuse, forced intercourse, and other circumstances, place women at risk of unintended pregnancy. There is a criti...
