Michel Garenne
Michel L. Garenne, Ph.D.[a 1] (demography), is Director of Research at the French Institute for Research and Development (IRD) and is currently working at the Institut Pasteur, Emerging Diseases Unit, in Paris. He is also honorary Associate Professor at the University of Witwatersrand, Johannesburg. He directed the Niakhar Demographic Surveillance System in Senegal in the 1980s and has collaborated with the Agincourt Health and Demographic Surveillance System in South Africa since 1992. He is the author of numerous publications on population and health issues in Africa, and has taught demography at several universities in Europe (Paris, Clermont‑Ferrand, Heidelberg, Antwerp), and in the United States (Harvard).
His main research interest is on public health issues seen from a demographic perspective.[1]

No net effect of circumcision on HIV
In 2022, Garenne investigated the complex relationships between circumcision and HIV prevalence in Lesotho and found no net effect of circumcision on HIV. The study (see below) questions the amount of effort and money spent on VMMC in Lesotho.
Population-based studies
New population-based studies (2021) confirm Garenne's findings.
September 2021 saw the publication of two huge population studies on the relationship of circumcision and HIV infection:
- Mayan et al. (2021) carried out a massive empirical study of the male population of the province of Ontario, Canada (569,950 males), of whom 203,588 (35.7%) were circumcised between 1991 and 2017. The study concluded that circumcision status is not related to risk of HIV infection.[2]
- Morten Frisch & Jacob Simonsen (2021) carried out a large scale empirical population study in Denmark of 855,654 males regarding the alleged value of male circumcision in preventing HIV and other sexually transmitted infections in men. They found that circumcised men have a higher rate of STI and HIV infection overall than intact men.[3]
No association between lack of circumcision and risk of HIV infection was found by either study. There now is credible evidence that the massive, expensive African circumcision programs have not been effective in preventing HIV infection.
