Impact of sexual habits on the clinical evaluation of male HPV infection.

A series of 199 male regular sexual partners of women attending an STD clinic for the examination and treatment of HPV-associated diseases was examined by peniscopy, surgical biopsy and nucleic acid hybridization for the presence of clinical, histological and molecular markers pathognomic of HPV infection. There was a 100% correlation between condylomata acuminata and detection of HPV type 6 or 11 DNA. Papillary lesions displayed neither histological signs of HPV infection, nor did they harbor HPV DNA (viral types 6, 11, 16, 18, 33) while 44.9% (22/49) of acetowhite epithelia showed HPV-suggestive histological changes. Of the 19 analysed for HPV DNA, 15.8% (3/19) harbored HPV 6/11 and 16 DNA. Regular male and female sexual partners did not always harbor the same HPV types, showing that latent or occult infection and the sexual habits of each individual play an important role in the clinical manifestations of HPV infection observed in sexual couples. The present data show that: i) the likelihood of developing a clinical HPV lesion was affected, to a large extent, by the previous sexual history and habits in the partners of women with flat condylomata, while partners of women with condylomata acuminata or CINs displayed a higher correlation with the current state of infection in their regular partner; ii) despite the assessed infective state of their consorts, men with a low lifetime number of sexual partners seldom displayed HPV-associated acetowhitening.(ABSTRACT TRUNCATED AT 250 WORDS)
