To estimate the real-use contraceptive effectiveness of the combined oral contraceptive (COC) containing dienogest and oestradiol valerate (DNG/oEV) compared to other combined oral contraceptives (oCOC) and particularly, levonorgestrel-containing OCs (LNG). Prospective, non-interventional cohort study with two main exposure groups and one exposure subgroup: new users of DNG/oEV and oCOC, with the subgroup, LNG. In a planned secondary analysis, pregnancy outcomes were investigated, including contraceptive failure.

Objectives: The objective of this analysis was to identify intra-uterine devices (IUD) perforations detected from 12 to 60 months following IUD insertion, and to combine this information with (our previously published) data about perforations detected in the first 12 months to calculate cumulative perforation rates.
Methods And Materials: Prospective, non-interventional cohort study with new users of levonorgestrel-releasing intra-uterine systems (LNG-IUS) and copper-IUD. The original cohort included 61,448 women followed for 12 months.
Objective: The objective of the study was to determine if delivery and lactation are risk factors for complete intrauterine device perforations.
Study Design: We performed a reanalysis of the European Active Surveillance Study on Intra-Uterine Devices data set using complete penetration of the myometrium as the definition for perforation.
Results: Of the 61,448 women enrolled (70% levonorgestrel, 30% copper devices), we identified 58 complete perforations, 30 of which occurred in lactating women.

Objectives: To estimate the real-use contraceptive effectiveness of the combined oral contraceptive containing dienogest and estradiol valerate (DNG/EV) and whether DNG/EV compared to other combined oral contraceptives (oCOC) has a negative effect on return to fertility.
Methods: Transatlantic, prospective, non-interventional cohort study conducted in the USA and seven European countries with two main exposure groups and one exposure subgroup: new users of DNG/EV and other COC (oCOC), particularly levonorgestrel-containing COCs (LNG). In a planned secondary analysis, pregnancy outcomes were investigated including contraceptive effectiveness and pregnancy following contraceptive cessation.

Objectives: The International Active Surveillance study "Safety of Contraceptives: Role of Estrogens" (INAS-SCORE) investigated the cardiovascular risks associated with the use of a combined oral contraceptive (COC) containing dienogest and estradiol valerate (DNG/EV) compared to established COCs in a routine clinical setting.
Study Design: Transatlantic, prospective, noninterventional cohort study conducted in the United States and seven European countries with two main exposure groups and one exposure subgroup: new users of DNG/EV and other COC (oCOC), particularly levonorgestrel-containing COCs (LNG). All self-reported clinical outcomes of interest (OoI) were validated via attending physicians and relevant source documents.

Objectives: To compare incidence rates of serious cardiovascular events, particularly arterial thromboembolic events (ATE), in users of hormone replacement therapy (HRT), particularly oral continuous combined preparations.
Methods: Prospective, controlled cohort study with four arms: women using (1) drospirenone (DRSP)/estradiol, (2) other oral continuous combined HRT (HRTcc), (3) all other oral HRTs, and (4) non-oral HRT. The study population consisted of women aged 40+ years in seven European countries who were new users of HRT at the time of inclusion.
Objectives: The "Long-term Active Surveillance Study for Oral Contraceptives" investigated the risks of long-term use of a 21-day regimen of drospirenone and ethinylestradiol (DRSP) compared to established oral contraceptives (OCs) in a routine clinical setting.
Study Design: Prospective, controlled, non-interventional cohort study conducted in seven European countries with three main exposure groups: new users of DRSP, levonorgestrel-containing OCs (LNG), and OCs containing other progestogens (Other OCs). All self-reported clinical outcomes of interest (OoI) were validated via attending physicians and relevant source documents.

Objectives: The "International Active Surveillance Study of Women Taking Oral Contraceptives" investigated the risks of short- and long-term use of an extended 24-day regimen of drospirenone and ethinylestradiol (DRSP24d) compared to established oral contraceptives (OCs) in a routine clinical setting.
Study Design: Prospective, controlled, noninterventional cohort study conducted in the United States and six European countries with three main cohorts: new users of DRSP24d, DRSP21d (21-day regimens of DRSP-containing OCs), and non-DRSP (OCs without DRSP). All self-reported clinical outcomes of interest (OoI) were validated via attending physicians and relevant source documents.

Objectives: : To assess the effects of premenstrual disorders on health-related quality of life (HR-QOL), hobbies and social activities, and relationships with others in the multinational IMPACT study.
Methods: : Women aged 15-45 years were screened for suspected premenstrual dysphoric disorder (PMDD) and premenstrual syndrome (PMS) and invited to participate in this web-based study. Based on the Daily Record of Severity of Problems (DRSP), prospectively assessed over two observational cycles, participants were grouped into two categories: no perceived symptoms/mild PMS or moderate-to-severe PMS/PMDD.
Background: This study investigated whether gestodene-containing oral contraceptives (OCs) carry a higher risk of venous thromboembolism (VTE) than OCs containing progestins other than desogestrel and gestodene. The study was conducted based on the hypothesis that the biases and confounding factors that were present initially after the introduction of new so-called "third-generation" OCs (i.e.
