Subclinical human papilloma a virus is a potential carcinogen in the m
ale and female genital tract. The sexually active male infertility pop
ulation represents a high risk group for harbouring this disease. To d
etermine the prevalence of subclinical human papillomavirus in this gr
oup, penoscopy was done on 96 male patients visiting the infertility c
linic. The feasibility of routine penoscopy as part of the infertility
work-up was also investigated. Of the 96 patients 20 had acetowhite l
esions on their penes with penoscopy. Thirteen patients (13.5%), 12 pr
oven by biopsy of the aceto-white lesions, and one proven by fluid in
situ hybridization on superficial epithelial cells of the distal ureth
ra, were positive for human papillomavirus. Two of the 12 biopsy-posit
ive cases were also proven positive by fluid in situ hybridization. It
was concluded that human papillomavirus had a high prevalence amongst
asymptomatic male patients attending the infertility clinic and that
penoscopy should be included as routine investigation in the work-up o
f the male infertility patient.
