The Multicenter AIDS Cohort Study (MACS) is an ongoing cohort study involving over 6,000 men, including both those infected with HIV, as well as HIV-negative men. The Los Angeles component of the MACS is called the Los Angeles Mens Study or LAMS. LAMS affiliated with UCLA and is supervised by Dr Roger Detels, MD & John Oishi.

The study, a program of the Division of Acquired Immunodeficiency Syndrome, has been ongoing for over 30 years and has resulted in over 1,000 scientific publications. It helped to establish that AIDS was a viral illness and how it was spread. Participants were quizzed in detail about their sexual behaviour. "They ask you for numbers, how many times did you do what." Some participants who had many sexual partners were not infected, and this led to the realisation that some people had genetic resistance to the virus.[1][2]
