Attitude and Involvement Regarding Sexual and Reproductive Health Among University Students: A Cross‐Sectional Study in Bangladesh

Health Science Reports, Volume 9, Issue 3, March 2026.
ABSTRACT Background and Aims Sexual and reproductive health (SRH) is a crucial aspect of overall health and well‐being, especially among young adults. However, in many low‐ and middle‐income countries, including Bangladesh, SRH issues remain underexplored due to sociocultural taboos, stigma, and inadequate education.
