The evidence · MSM
What the published reviews of MSM concluded
- Meta-analysis: prevalence of HIV infection and syphilis among MSM in China. · Sexually transmitted infections, 2009
“MSM are a high-risk population for HIV infection in China. An effective strategy for prevention and control is required for this specific population. Differences between sampling methods, sample sizes and study locations may explain some of the inconsistencies found in the included studies.”
- Association of nitrite inhalants use and unprotected anal intercourse and HIV/syphilis infection among MSM in China: a systematic review and meta-analysis. · BMC public health, 2020
“Nitrite inhalant users have higher HIV and syphilis prevalence by increasing levels of high-risk sexual behaviors.”
- Weekly Text Messages to Support Adherence to Oral Pre-Exposure Prophylaxis (PrEP) Among Gay, Bisexual, and Other Cisgender Men Who Have Sex With Men (MSM) and Transgender Women: Pilot Randomized Controlled Trial Nested in PrEP Brasil Study. · Journal of medical Internet research, 2025
“SMS text messaging intervention improved adequate PrEP adherence among young MSM and can be a useful tool for PrEP coverage and persistence.”
- The pharmacokinetics, pharmacodynamics, and mucosal responses to maraviroc-containing pre-exposure prophylaxis regimens in MSM. · AIDS (London, England), 2019
“MVC-containing HIV PrEP regimens did not increase GALT CD4+ T-cell activation or the CD4+/CCR5+ phenotype. No virologic suppression was seen with MVC-alone at Week 48 compared with combination regimens, suggesting MVC monotherapy might be less effective than combination antiretroviral PrEP regimens.”
Method: PubMed searched in humans for systematic reviews, meta-analyses and randomised trials with MSM in the title; these 4 of the 7 that qualified are shown with the authors’ own conclusion quoted rather than summarised. What it cannot tell you: whether MSM will work for you — each of these reports an average across trials published 2009–2025, and null findings are shown here as readily as positive ones.
How these 12 MSM products were ranked
Not one of these 12 MSM products could be confirmed in the NSF, USP or Informed Sport registries, so verification separates none of them and the ranking falls to cost per day at the labelled serving. Commission does not enter it: the rate is the same whichever MSM you buy. Full methodology.
