NCT07075536
A Web-Based Tool to Help People With Health Conditions Make Contraceptive Decisions
Among people who do not want to get pregnant, some do not use any birth control. This is also called contraceptive nonuse. Common reasons for contraceptive nonuse include concerns about birth control safety or side effects. People with health conditions, such as diabetes or high blood pressure, also report worries about how different birth control methods might affect their health condition or medicines. The goal of this clinical trial is to learn if a web tool called My Health, My Choice helps people with health conditions understand their birth control options and choose birth control that is right for them. The study will also look at the medical safety of birth control methods that participants decide to use. The main questions it aims to answer are: • Does the My Health My Choice tool lower the number of participants who do not use any birth control method? (contraceptive nonuse) In other words, does the My Health My Choice tool increase the number of participants who use any birth control method? (contraceptive use) Participants who use the My Health, My Choice tool before a clinic visit with their clinician (Intervention Group) will be compared to participants who only go to a clinic visit with their clinician (Usual Care Group). For this study, a "clinician" is any licensed health care provider who counsels about birth control, prescribes birth control, and/or inserts birth control devices. All participants will: * Complete 4-5 online surveys that take 5-10 minutes each, over a 3 month time period * Be asked to go to a scheduled clinic visit with their health care provider * A small group of participants (about 30) will be invited to a 1 hour exit interview Participants in the intervention arm will be asked to: • Use the My Health My Choice tool before their clinic visit

Efficacy, Safety, and Tolerability of Levonorgestrel Vaginal System
The goal of this clinical trial is to learn if drug levonorgestrel vaginal ring works as a contraceptive adult and adolescent females who are able to conceive (i.e. get pregnant). It will also learn about the safety and tolerability of levonorgestrel vaginal ring. The main questions it aims to answer are: Does drug levonorgestrel vaginal ring lower the number of pregnancies with continued use? What adverse effects do participants experience by using levonorestrel vaginal ring? Researchers will count the number of pregnancies with levonorgestrel vaginal ring after a participant uses it for a year to see if the number of pregnancies is low (i.e. women and girls do not get pregnant). Participants will: Use levonorgestrel vaginal ring for 28 days (called one cycle); for a total of 14 cycles (which is a little more than year) Visit the clinic about 8 to 10 times over about 14 months for checkups and tests with an additional approximately 13 phone calls Keep a diary of their pregnancies and number of times they use additional contraceptive (e.g. condoms)

Disparities in Emergency Contraceptive Metabolism Dictate Efficacy
The purpose of this study is to learn more about why some people are at greater risk for oral emergency contraceptive failure while others are not. The investigators want to learn if genetic differences impact the risk of emergency contraception failure.

Community-based Venues for Delivery of Healthcare Services: Proof of Concept Pilot
The investigators propose to offer a package of evidence-based health services to women in two hair salons in the Umlazi township of Durban. Based on community feedback in previous survey and qualitative work, the package has been designed to include daily PrEP, family planning/contraceptives, and STI screening. Interested salon clients at intervention salons will elect which services to use. An additional salon will serve as control, offering no health services to clients. Surveys will be conducted in both salon groups. Attendance at follow-up visits for monitoring and medication refill will be encouraged using text message reminders, WhatsApp support groups, and lottery-based incentives for free salon services. Recruitment in intervention salons will conclude when 100 clients uptake PrEP, not inclusive of clients who enroll at intervention salons who accept other services through the study. Approximately 250 participants will be recruited in control salons. The study team anticipates an overall total enrollment of 500.

Peer-led Service Delivery Model for Pregnant and Lactating Adolescent Girls and Young Women in Zimbabwe
This is a pilot cluster-randomized control trial co-led by Dr. Valentina Cambiano, Associate Professor of Epidemiology at University College London, UK and Professor Euphemia Sibanda, Research Director at the Centre for Sexual Health and HIV Research (CeSHHAR Zimbabwe). The goal of the proposed study is to evaluate the appropriateness, feasibility, acceptability, uptake, costs and cost-effectiveness of a community-based, HIV-status neutral peer-led service delivery model in which young mentor mothers (YMM) work with pregnant and lactating adolescent girls and young women (PL-AGYW, aged 15-24), up to two-years post-birth, in Zimbabwe to promote uptake of contraception and HIV prevention. YMM living with HIV have been found to be effective in supporting their peers for prevention of mother-to-child transmission of HIV and adherence to treatment through the "Zvandiri" programme. The investigators propose adapting the "Zvandiri" YMM to include those without HIV to promote behaviour to prevent HIV and unintended pregnancies. This proposed intervention is building on the formative work that had the overall aim of co-developing with AGYW (aged 15-24) a Pre-Exposure Prophylaxis (PrEP) implementation intervention for AGYW who need it, that attracts them to PrEP, and supports pregnant and lactating adolescent girls and young women while taking it.

Sexual Health Empowerment for Women's Health
The purpose of this study is to expand the reach of an existing cervical cancer literacy and prevention intervention- the Sexual Health Empowerment (SHE) Project . As a logical extension of the investigators earlier work, the objective of this renewal is to expand reach of SHE to address women's health disparities more broadly to create a sustainable model for dissemination of health promotion interventions for vulnerable populations.

RCT Evaluating Standardized Counseling on Early Discontinuation for Irregular Bleeding in Nexplanon Users
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.

The Over The Counter Pill National Study
This is a prospective cohort study of individuals purchasing the oral contraceptive pill over the counter (OTC) in pharmacies in 32 US states. The comparison group is people receiving a prescription (Rx) for oral contraception. Both groups will be followed for one year to examine contraceptive continuation rates. This study will also identify who is using the pill OTC and why and evaluate differences in pregnancy intention and measures of contraceptive agency between the two groups.
