Men who have sex with men (MSM) in Kenya face a disproportionately high burden of HIV. Stigma and discrimination present significant barriers to conventional facility-based testing. HIV self-testing (HIVST) is a potential strategy to increase coverage, but requires effective distribution models for this key population. This study aimed to evaluate the effectiveness of a peer-led HIVST distribution model in increasing HIV testing uptake and frequency among MSM in Mombasa, Kenya. A quasi-experimental intervention study was conducted. A total of 350 MSM were enrolled and assigned to either an intervention arm or a control arm. The intervention arm received HIVST kits and support from trained MSM peers. The control arm received standard-of-care testing referrals. Data were collected via structured questionnaires at baseline and at a six-month follow-up to assess testing outcomes and experiences. The peer-led intervention significantly increased recent HIV testing uptake. At follow-up, 92% of participants in the intervention arm reported testing for HIV in the past three months, compared to 58% in the control arm. Qualitative feedback indicated that peer support helped to overcome testing anxieties. A peer-led HIVST distribution model was effective in increasing HIV testing uptake and frequency among MSM in Mombasa. This demonstrates its potential to improve testing accessibility for this marginalised group. HIV prevention programmes should consider integrating peer-led HIVST distribution into existing services for MSM. Further research is needed to assess the model's cost-effectiveness and its impact on linkage to confirmatory testing and care.
