In our previous study, we measured 0.23-13.67ng/L progestogens (progesterone, drospirenone, levonorgestrel) in natural waters in the catchment area of the largest shallow lake of Central Europe, Lake Balaton. Progestogen contaminations act as potent steroids with mixed progestagenic, androgenic and mild estrogenic effects that is why our aim was to investigate the morphological and molecular effects of mixture of progesterone, drospirenone, and levonorgestrel in environmentally relevant (10ng/L) and higher (50 and 500ng/L) exposure concentrations in common roach, Rutilus rutilus...

OBJECTIVES: Venous thromboembolism (VTE) risk increases within months of combination oral contraceptive (COC) initiation. Because elevated endogenous thrombin potential (ETP) has been found in several studies to be a VTE risk factor, we evaluated the extent of ETP changes during the initial cycle of an ethinyl estradiol (EE) and levonorgestrel (LNG) COC. We also assessed the relationship between ETP changes and systemic EE and LNG concentrations. STUDY DESIGN: Participants provided multiple blood samples during a first 21-day cycle of a 30 μg EE/150 μg LNG COC and after a further 7 days without an active COC...

AIM(S): This study aimed to investigate whether cabotegravir (CAB), an integrase inhibitor in development for treatment and prevention of HIV-1, influences the pharmacokinetics (PK) of a levonorgestrel (LNG) and ethinyl estradiol (EE)-containing oral contraceptive (OC) in healthy women. METHODS: In this open-label, fixed-sequence crossover study, healthy female subjects received LNG 0.15 mg/EE 0.03 mg tablet once daily Days 1-10 alone and with oral CAB 30 mg once daily Days 11-21...

OBJECTIVE: Users of hormonal long-acting reversible contraception (LARC) report weight gain as a side effect, but few studies have assessed body composition change among LARC users. We evaluated weight and body composition of healthy women using the levonorgestrel intrauterine system (LNG-IUS), copper intrauterine device (copper IUD) or etonogestrel implant (ENG implant). We hypothesized that weight gain and body composition over 12 months would not differ between copper IUD, LNG-IUS and ENG implant users...

OBJECTIVE: The gold standard for measuring oral contraceptive (OC) pharmacokinetics is the 24-h steady-state area-under-the-curve (AUC). We conducted this study to assess whether limited sampling at steady state or measurements following use of one or two OCs could provide an adequate proxy in epidemiological studies for the progestin 24-h steady-state AUC of a particular OC. STUDY DESIGN: We conducted a 13-sample, 24-h pharmacokinetic study on both day 1 and day 21 of the first cycle of a monophasic OC containing 30 μg ethinyl estradiol and 150 μg levonorgestrel (LNG) in 17 normal-weight healthy white women, and a single-dose 9-sample study of the same OC after a one-month washout...

OBJECTIVE: Immediate postpartum intrauterine devices (IUDs) have been underutilized in the United States despite their known safety. Understanding how providers' attitudes contribute to underutilization is important in improving access. Our objective was to examine healthcare providers' perceptions of the safety of immediate postpartum IUDs before publication of United States contraceptive guidelines. MATERIALS AND METHODS: We analyzed survey data collected from December 2009 to March 2010 from 635 office-based physicians and 1368 Title X clinic providers (overall response rate of 64...

BACKGROUND: Heavy menstrual bleeding affects as many as one in three women and has negative physical, economic, and psychosocial impacts including activity limitations and reduced quality of life. The goal of treatment is to make menstruation manageable, and options include medical therapy or surgery such as endometrial ablation or hysterectomy. This review examined the evidence of effectiveness and cost-effectiveness of the 52-mg levonorgestrel-releasing intrauterine system (LNG-IUS) as a treatment alternative for idiopathic heavy menstrual bleeding...

REVIEW
Rachel E Zigler, Colleen McNicholas
Nearly 20% of women using contraception are using progestin-only contraception, including progestin-only pills, depot-medroxyprogesterone acetate, subdermal etonogestrel implants, and levonorgestrel intrauterine devices. This number will continue to grow with the increased provision of long-acting reversible contraception. Although overall satisfaction among women using progestin-only contraception is high, dissatisfaction and discontinuation may be associated with unscheduled bleeding and spotting. The exact etiology of irregular bleeding associated with progestin-containing contraceptives is not completely understood, yet several mechanisms have been suggested...

Obesity is a significant risk factor for the development of endometrial hyperplasia and cancer. More conservative prevention and management strategies are attractive due to the increased surgical risk and complication rates associated with obesity. The Levonorgestrel-releasing intrauterine system (LNG-IUS, Mirena) has been shown to reduce the risk of developing endometrial cancer. The recent joint Green Top Guideline on the Management of Endometrial Hyperplasia published by the Royal College of Obstetricians and Gynaecologists (RCOG) with the British Society for Gynaecological Endoscopy (BSGE) recommends the LNG-IUS for the medical management of endometrial hyperplasia without atypia...

The risk-benefit profile of any pharmacologic agent must be evaluated against risks connected with the events to be avoided. This is especially true in the case of hormonal contraception, not intended to combat a disease. Over the six decades during which their use has progressively expanded, the risk-benefit profile of combined oral contraceptives (COC) has substantially changed, with new combinations, dosages and mode of administration appearing on the market. Area covered: In a series of articles, recent information on the complex issue of COC risks and benefits will be reviewed in the hope of providing an updated picture...

Chronic vulvovaginal candidiasis is usually responsive to therapy with oral antifungals. We present a case series of 13 patients with this condition who were also using a levonorgestrel intrauterine system (LNG-IUS). All cases responded to ongoing oral fluconazole therapy while the LNG-IUS was in situ. The LNG-IUS was removed in six patients and of these, two experienced clinical improvement with lower fluconazole dosage requirements and three experienced complete resolution of symptoms. One remains on fluconazole 100 mg daily...

BACKGROUND: Contraceptive implants (including Jadelle) are highly effective, safe, and easy to use and have a long duration of action. They do not interfere with intercourse with immediate return to fertility after removal. However, disruption of the menstrual bleeding pattern is almost inevitable and coercive prescription may be a problem because insertion and removal of implants are provider dependent. The objective of this study was to determine the sociodemographic profiles of acceptors of Jadelle and the reasons for discontinuation in Jos, Nigeria...

STUDY QUESTION: Has there been any influence of the Zika virus (ZIKV) outbreak on the sales of contraceptive methods in Brazil? SUMMARY ANSWER: Contraceptive sales in the 24 months of evaluation showed little variation and no significant change has been observed since the ZIKV outbreak. WHAT IS KNOWN ALREADY: Transmission of ZIKV is primarily by Aedes aegypti mosquitoes; however, sexual transmission has also been described. The association of several birth defects and the ZIKV infection during pregnancy has been established, and it was estimated in Bahia, Brazil that the infection rate could range from 10% to 80%...
