Background: In Argentina, transmission among men who have sex with men (MSM) hasn´t changed significantly its percentage between 2001-2007 (31.1%- 32.9%). New infections occur predominantly among well-educated and young men. New alternatives for HIV and STI prevention are necessary for this group, such as microbicides

Methods: The objective of the study is to identify factors related to the acceptability and willingness to use new prevention methods among MSM. 200 individuals with different HIV status will be surveyed through an online questionnaire. In order to adjust questions to the target population a previous survey used with women was modified with data collected among MSM stakeholders. The questionnaire developed includes the following variables: demographics, perception of HIV-risk, HIV status, condom use, use of lubricants, rectal douching, rectal products and pre and post-prophylaxis; sexual practices, HIV-related knowledge and psychological aspects (gender-roles, locus of control and attitudes towards health).

Results: The pilot study with 38 MSM determined appropriateness of the survey, 9 of them were PLHIV. Participants were between 21 and 62 years old and completed secondary school or higher level of education. Results revealed that 78,9% use condoms most of the times. 76,6% of them would like to use a microbicide with a condom and 20% would like to use only a microbicide next time they have intercourse. Among the participants who do not use condom usually (22,1%), most of them will use only microbicides (62,5%).

Conclusions: High level of condom use revealed an increased awareness in this population. Most participants who use condoms are willing to use microbicides as double protection. MSM who do not use condom regularly are willing to use microbicides as the only prevention method. The study is in collection process and final results in a larger sample are expected by mid year.
