To further investigate the vertical transmission route of human papillomavirus (HPV) and the indication for the choice of mode of delivery, the infective status of 152 asymptomatic pregnant wemen and the maternal-fetal transmission were studied. By using general primers in polymerase chain reaction (GP-PCR) combined with restriction fragment length polymorphism analysis, HPV DNA positive rate in cervical secretions and venous blood in asymptomatic pregnant women was 36.21% and 52.78%, respectively, and the identified genotypes were mainly HPV16 and 18. The maternal-fetal transmission rate of HPV via genital tract as well as blood was 40.91% and 57. 89%, respectively. It was concluded that besides the transmission route of genital tract and amniotic fluid, there was also transplacental transmission of HPV in utero. Therefore,in our opinion, it is not an absolut indication to perform a cesarean delivery for the pregnant women with HPV asymtomatic genital infection.

Human papillomavirus (HPV) infection is one of the worldwide sexually transmitted diseases (STD), and the DNA of HPV can exist in the normal epithelium of reproductive organs of both men and women. Because the majority of HPV infections are asymptomatic, healthy HPV-carriers become the main source of the infection. Studies show that HPV infection in men is correlated with STD, infertility, tumor of reproductive organs, and infection in the sexual partners. Therefore, measures should be taken to reduce male HPV infection, including circumcision, fewer sexual partners, and condom use.

OBJECTIVETo investigate the association of human papillomavirus (HPV) in the pubic hair follicles of males with HPV infection in their female sexual partners.

METHODSWe included in this study 21 female patients with HPV infection, including 8 cases of cervical cancer, 5 cases of atypical cervical hyperplasia, 5 cases of cervical condyloma, and 3 cases with unidentified causes. We also enlisted 52 men without visible condyloma acuminatum in the external genitalia as healthy controls. We detected HPV in the pubic hair follicles of the female patients' male sexual partners and the healthy male controls by PCR and reverse hybridization in situ.

RESULTSHPV positive was found in 6 (28.6%) of the 21 women's male partners, in whom the HPV types were correspondent situ. to those of the female patients.

CONCLUSIONHPV in the pubic hair follicles of men might be one of the causes of HPV-related cervical lesions in their female sexual partners.
