Objective: This study aimed to evaluate whether use of period- or fertility-tracking technologies decreased from pre- to post-Dobbs, and to identify user characteristics and changes in reasons for use.
Study Design: We used data from the Surveys of Women, population-based surveys on reproductive health among self-identified women aged 18-44 years, conducted in five states. We compared prevalence of use of period- or fertility-tracking technologies and reasons for use pre-Dobbs (2018-2019 in Iowa and Ohio; 2019-2020 in Arizona, New Jersey, and Wisconsin) and post-Dobbs (2022-2023 in all five states), overall and stratified by state. To examine prevalence of use, we adjusted for age, race/ethnicity, education level, and marital status.
Results: Period- or fertility-tracking technology use increased from pre-Dobbs to post-Dobbs overall, with an adjusted prevalence ratio (aPR) of 1.20 (95% CI 1.15-1.26). User prevalence increased in four of the five states: Arizona (aPR=1.17; 95% CI 1.06-1.30), Iowa (aPR=1.32; 95% CI 1.19-1.47), New Jersey (aPR=1.21; 95% CI 1.11-1.31), and Ohio (aPR=1.28; 95% CI 1.16-1.40); prevalence was unchanged in Wisconsin (aPR=1.06; 95% CI 0.95-1.18). The only change in reason for use was a decrease in reports of using an app "to become pregnant" post-Dobbs (aPR=0.85; 95% CI 0.75-0.97).
Conclusion: The increase in period- or fertility-tracking technology use pre- to post-Dobbs may demonstrate that data privacy was less of an issue for users than anticipated.

New contraceptive fertility tracking apps (CFTAs)-that are backed by clinical efficacy trials to support their effectiveness as contraception-have the potential to enhance method choice and offer users a unique contraceptive option, but there is little evidence to inform the decisions around expanding access, particularly in low-and middle-income countries. We conducted a mixed methods study with quantitative online surveys (n = 1600) and qualitative interviews (n = 36) to explore the potential appeal of and demand for a hypothetical CFTA in one such market, the Philippines.

Article Synopsis
- - The Dobbs v. Jackson decision by the U.S. Supreme Court in June 2022 removed federal protections for abortion, raising concerns about reproductive rights and the use of health data in research.
- - This study analyzed data from a preconception cohort study, focusing on participant engagement before and after the Dobbs ruling, particularly in relation to their state's abortion access.
- - Results showed that in states with banned or restricted abortion rights, there was a significant 27.12 percentage point drop in participants clicking on a fertility-tracking app compared to states with limited or protected rights, indicating a decrease in engagement linked to the Dobbs decision.
Time to pregnancy recognition among users of an FDA-cleared fertility application.

Natural Cycles Nordic AB, Stockholm, Sweden.
Previous investigations of time-to-pregnancy recognition have analysed data from national surveys and clinics, but this has not been investigated in the context of digital fertility applications. Timely pregnancy recognition can help individuals in health and pregnancy management, reducing maternal and foetal risk and costs, whilst increasing treatment options, availability, and cost. This dataset contained 23,728 pregnancies (conceived between June 2018 and December 2022) from 20,429 participants using a Food and Drug Administration (FDA) cleared fertility app in the United States.
