The objective of the present study was to demonstrate the impact of HPV diagnosis on sexual function and mental health of Greek women. The study population included 51 patients who proceeded to the gynecological outpatient clinic of “Aretaieion” Hospital, Athens, during 2008-2009. The participants were asked to complete a questionnaire regarding demographic characteristics, knowledge on HPV, gynecological and sexual history, as well as questions regarding their mental and sexual health after the diagnosis. Mean age of the participants was 36 years and mean age of their first Pap smear test was 24.4 years. Mean age of HPV diagnosis was 34 years and mean number of sexual partners was four. Regarding mental health, the majority experienced anxiety after the HPV diagnosis as well as fear regarding their health in the future. Nearly half of the women experienced guilt and anger and some of them distress, shame, diminution of self-esteem and stigmatization. Diminution in the level of sexual interest and desire and decrease in sexual intercourse frequency were quite often reported. Except for the important physical impact of HPV infection, its diagnosis seems to trigger several negative feelings and reduce sexual desire.
