Filter by:Multinational, comparative, prospective, active surveillance study that follows two cohorts. The primary objective of the study is to characterize and compare the risks of E4/Drospirenone (DRSP) with levonorgestrel-containing combined oral contraceptives (EE/LNG) in a study population that is representative of the actual users of these preparations. The main clinical outcome of interest is venous thromboembolism (VTE), specifically deep venous thrombosis (DVT) and pulmonary embolism (PE). Secondary objectives include measuring the occurrence of unintended pregnancy, assessing the risk of arterial thromboembolism (ATE), describing the drug utilization pattern, describing the baseline risk profile for VTE and ATE, and investigating outcomes associated with foetal exposure to E4/DRSP.
Effects of norethindrone acetate (NTA) in patients with Nexplanon.
Clinician counseling for implant users should involve an explanation of the likelihood of irregular bleeding and the possibility of continued or frequent bleeding throughout three years of use. If that counseling does not provide specifics of the actual distribution of bleeding patterns described in published literature, there remains the real possibility of biased or directed counseling, leading to an inaccurate and exaggerated expectation of potential bleeding changes. This study aims to evaluate if a standardized script accompanied by a visual aid regarding expected bleeding profiles, with intention to remove any possibility of negative or positive framing, could change users' expectations and satisfaction with their method, leading to lower discontinuation rates.
This study aims to understand the long-term health, social, and economic impacts of transitioning a community to Highly Effective Reversible Contraception (HER-C).
This project will quantify rates of contraceptive failure when unprotected intercourse occurs 6-14 days prior to initiation of highly effective reversible contraceptives (such as IUD's and Implants).
Anti-mullerian hormone (AMH) has been shown to be a reliable marker of ovarian reserve. In prior studies, tubal ligation has been shown to have an adverse effect on ovarian reserve. One theory postulated for this effect is that the ovarian circulation is disrupted by the procedure, leading to altered hormone production. In this prospective cohort study, the investigators plan to analyze the rates of AMH decline by comparing the following contraceptive methods: tubal ligation, Essure placement, and levonorgestrel intrauterine devices (IUDs).
This is a comparative, open-label two-period crossover study of up to 505 couples comparing the PATH Woman's Condom to the FC2 female condom. California Family Health Council will enroll up to 505 couples to have 375 complete both periods. The study will provide data on functional performance, vaginal semen exposure, safety, and acceptability of the two female condoms. Both partners will be required to come to the clinic to be consented for the study. If both members of the couple meet all eligibility requirements, they will each sign an informed consent form and will be enrolled as a couple. The couples will be randomized to one of two female condom use sequences for the two periods (WC then FC2 or FC2 then WC). For the first period of 2-4 weeks, the couple will be asked to have sex once without a condom and 4 times using the first assigned female condom. For the second period of 2-4 weeks, the couple will be asked to have sex 4 times using the second assigned female condom. In the first period, the couple will have one act of unprotected sex for which they will collect pre- and post-coital vaginal swabs. The couple will also use 4 female condoms of the assigned type. They will be asked to collect pre- and post-coital vaginal swabs and a post-coital swab from the condom interior. The couple will complete a detailed Condom Use Questionnaire together after each condom use. An Acceptability Questionnaire will be completed separately by males and females at the end of each study period. Couples may have additional acts of sex during each period as they desire but will not have sex at least 48 hours prior to each study sex act. After a follow-up visit, the procedures will be repeated with 4 of the second assigned condom type but without the collection of vaginal swabs at unprotected intercourse. Each couple will be enrolled for about 2-3 months, depending on the intervals between sex acts. Clinicians evaluating product-relatedness of AEs will be blinded to the condom type used. Male partners will be requested to attend the final visit, and, if they experience adverse events, the followup and/or unscheduled visits.
