Orogenital sex and the transmission of HIV among homosexual men.
OBJECTIVE
To investigate the possibility of orogenital transmission of HIV.


METHODS
Cohort study on HIV infection among homosexual men.


METHODS
The Municipal Health Service, Amsterdam, The Netherlands.


METHODS
Homosexual men for whom the date of HIV seroconversion was known (n = 102) were included in our study.


METHODS
Data on the sexual behaviour of our subjects in the 6-9 months preceding HIV seroconversion were collected. In order to identify those men who consistently denied practising receptive anogenital intercourse, information was retrieved from written questionnaires and from face-to-face interviews.


RESULTS
Receptive anogenital intercourse in the 6-9 months before seroconversion was denied by 20 seroconverters in their written questionnaires. However, in face-to-face interviews, 11 men later reported this sexual practice.


CONCLUSIONS
Orogenital transmission of HIV appears to occur, but its frequency may be overestimated because of reluctance to report the practice of receptive anogenital intercourse.
