We read the paper by Perkins et al. (2011) with great interest because it highlighted a very important issue about fathers' attitudes towards HPV infection and their intentions regarding HPV vaccine. No surveys have been published yet demonstrating the extent of fathers' knowledge of HPV and HPV vaccine together with its acceptance in Germany. In an attempt to fill this gap, we would like to share our findings from a recent pilot survey investigating the awareness of HPV infection and related health outcomes as well as HPV prevention by vaccination, in fathers and non-fathers attending the Munich University outpatient clinic (non-sexually transmitted infections/HIV or genito-urinary medicine).Between January and February 2010, consecutive male German-speaking patients who were 18 years of age or older were asked to participate in an anonymous cross-sectional survey on HPV, HPV vaccination and genitoanal neoplasms. Multiple regression was used to analyse the association between age, family status, education and parental status, and HPV-related knowledge, reporting adjusted odds ratios (ORs) with their 95% confidence intervals (95% CI). A p value \0.05 was considered as significant. Statistical analyses were performed using the PASW Statistics 18 software (SPSS, Chicago, IL). The survey was approved by the Ethics Committee of the Medical Faculty of LudwigMaximilian University.The final sample included 243 respondents (75.9% out of 320 questionnaires handed out). The median age of the participants was 44.4 (mean = 43.8, standard deviation ±15.2) years; almost half (43.6%, n = 106) of the respondents were married, 32.1% (n = 78) single, 45.7% (n = 111) fathers, one-third had a college (34.4%, n = 83) or university education (29%, n = 70), and 61.2% (n = 148) were in employment.Less than one-third (29.2% out of 243) of the participants had heard of HPV and only 14% of HPV vaccine. The HPV and genitoanal warts-related knowledge in the whole sample and by parental status is presented in Table 1. About half of our respondents were fathers who had, on average, 1.8 children (median = 2). Only 19.8% of fathers were aware of HPV, 8.2% had heard of HPV vaccine and only two of them let their daughters have the HPV vaccination; five would let their daughter get vaccinated if they had one. Non-fathers were significantly more aware of HPV and HPV vaccination than fathers (Table 1). Being a father was associated with an increased probability of not having heard of HPV (OR = 2.33, 1.29-4.19; n = 241), HPV vaccine (OR = 2.64, 1.17-5.94; n = 237) and not knowing of the causal link between HPV and genitoanal warts (asked as a one term) (OR = 2.03, 1.19-3.46; n = 234) compared to non-fathers.The study showed a very limited knowledge in males and especially in fathers regarding HPV infection and vaccination. In an Italian study, 76.9% fathers (of n = 1,093) had heard of HPV (Pelucchi et al. 2010) and in an American study, 85% (of n = 111) were aware of HPV vaccine (Cates et al. 2010).The majority of our respondents who were aware of HPV...
