OBJECTIVE The availability of family planning and abortion training in residency is a concern for applicants, particularly following the overturning of Roe v Wade. We aimed to characterize public information on abortion training in obstetrics and gynecology residency programs in states with and without abortion bans. METHODS We abstracted residency program data using a publicly available database of obstetrics and gynecology residency programs. We performed a systematic internet search of each program's website to identify information on abortion training. We defined states with abortion bans as those with total or near-total bans as of November 2022. Using Stata SE 16, we used Student t tests and Fisher exact tests to characterize differences between programs with public abortion training information and those without. RESULTS Of 293 obstetrics and gynecology residency programs, 197 (67.2%) included online information regarding abortion training. Of 64 programs in states with abortion bans, 34 (53%) had public information regarding abortion training, compared to 163 (71%) of the 229 programs in states with legal abortion. Programs with publicly available abortion training information were more likely to be academic (49.8% vs 26%, p < 0.001) and have a higher percentage of female residents (86.6% vs 82.9%, p = 0.003). Programs in states with legal abortion were more likely to use words like "abortion" (36.2% vs 17.7%, p = 0.05). CONCLUSIONS Only two-thirds of obstetrics and gynecology residency programs publicize abortion training information. Almost half of all programs in states with abortion bans do not share this information, revealing a need for improved transparency to better inform residency applicant decision-making. CONCLUSIONS During the 2022-2023 academic cycle, one-third of obstetrics and gynecology residency programs did not include information about family planning or abortion training online. In states with abortion bans, this number increased to almost one-half. These findings serve as a call to action for programs to clarify their commitment to abortion training.
