Design: All primary studies involving myomectomy published 2001- 2022 were identified. Study characteristics and number of participants included in each manuscript and their race and ethnicity were recorded. Data was analyzed to determine the proportion of studies reporting race, factors influencing reporting and the proportion of participants, and participant race and ethnicity.

Setting: N/A

Patients or Participants: N/A

Interventions: N/A

Measurements and Main Results: 558 studies met criteria for inclusion: 74 (12.6%) reported race and 37 (6.3%) reported ethnicity. Studies that reported race had higher odds of being more recently published, based in the United States and retrospective compared to studies published earlier in the study period, based internationally, and prospective (p-value < 0.001). Race reporting increased over time during the period of study. In 558 articles, 13 of the 15 largest studies reported race leading to race reporting for 374,771 (77.6%) participants. 302,907 (62.7%) participants had ethnicity reported. 67/74 (90.5%) articles reporting race did not specify how race was recorded and nearly all did not classify race beyond “White”, “Black”, and “Asian”.

Conclusion: Despite fibroids disproportionately affecting people of African descent, very few myomectomy studies published in the last 20 years report race and ethnicity. While there has been an increase in reporting of race/ethnicity over time, most studies do not adequately describe how race/ethnicity was determined and a large proportion are still using broad and non-standard categories.
