The Sexual Health and Reproductive Experiences (SHARE) Lab, directed by Dr. Madina Agénor, conducts cutting-edge quantitative, qualitative, and mixed-methods research on the social and policy determinants of sexual and reproductive health disparities in relation to various dimensions of social inequality – especially sexual orientation, race/ethnicity, and gender identity – using an intersectional and health equity lens.


Topics of study include: intersecting sexual orientation, racial/ethnic, and nativity disparities in cervical cancer screening and human papillomavirus (HPV) vaccination; sexual and reproductive health of sexual minority women, including Black sexual minority women; sexual and reproductive health of transmasculine individuals, including transmasculine people of color; and impact of policy– and provider-level factors on cancer prevention disparities and reproductive health equity.

Current SHARE Lab Projects

  1. Multilevel social determinants of HIV/STI testing among transmasculine young adults of color (funded by National Institute of Mental Health)
  2. Policy- and provider-level determinants of sexual orientation and racial/ethnic disparities in HPV vaccination and other sexual and reproductive health services among young U.S. women (funded by National Cancer Institute)
  3. Body image, romantic relationships, and sexual health among transfeminine and transmasculine young adults (with Dr. Allegra Gordon; funded by Aerosmith Endowment Fund)
  4. Intersecting sexual orientation and racial/ethnic disparities in contraceptive care among U.S. women
  5. Sexual orientation identity and gender identity disparities in sexual health services use among assigned female at birth adults in East Africa (with Dr. Michele Ybarra)
