Detection of high-risk HPV DNA in semen and its association with the quality of semen.

The effects of seminal high-risk human papillomavirus (HPV) DNA were assessed on the quality of semen. Semen samples of 65 men participating in the ongoing Finnish HPV Family Study were collected. Semen analyses were done by the guidelines of the Nordic Association for Andrology. HPV DNA was detected by nested polymerase chain reaction and confirmed by Southern blot hybridization for high-risk types. Altogether, 10/65 men (15.4%) had high-risk HPV DNA positive semen sample. Seminal high-risk HPV DNA did not affect semen volume, sperm concentration, motility and vitality of spermatozoa. However, semen pH was borderline lower in HPV DNA positive than negative samples (7.4 vs 7.5). Neither oligo- nor asthenozoospermia was associated with seminal HPV DNA. In conclusion, seminal high-risk HPV DNA was detected in 15% of men. It did not affect the semen analysis, except semen pH by borderline significance. Sperm donors have not been tested for HPV infections, sperm washing does not seem to eliminate the risk of HPV transmission and the consequences of HPV in the semen are at present unknown.

PAP smear after radiation therapy for cervical carcinoma.

Vaginal PAP smear is frequently used for the follow-up of cervical carcinoma after primary therapy. Irradiation induced atypia can interfere with cytological analysis and thus detection of a local recurrence, or simulate malignant atypia and cause unnecessary suspicion of recurrence. In this retrospective study we evaluated the reliability of cytological analysis and the reported frequency of irradiation induced atypia after radiotherapy. Eighty-nine patients treated for cervical carcinoma at Turku University Central Hospital during the years 1970-88 were included in the study. During the median follow-up of 34 months a total of 697 PAP smears were taken with a median of 7.8 samples per patient. During the follow-up 44 (50%) patients had a recurrent disease, which was local in 17 (39%) cases. Nine out of 12 PAP smears taken 0-60 days before detection of a local recurrence showed class III-V cellular atypia. However, three PAP smears showed class I-II, and were therefore false negative. The rate of false positive samples was only 3%. In 567 PAP smears irradiation induced atypia was indicated as present/not present (+/-) and it was positive in 89 (16%) samples. The detection rate was considerably higher (75%) in class II samples than in rest of the material. Irradiation induced atypia was detected in 28% of the PAP smears taken during the first four months after radiotherapy and the rate decreased thereafter. Cytological analysis of vaginal PAP smear was a reliable indicator of recurrence in most cases and is a valuable tool for the detection of local recurrence of cervical carcinoma after primary radiotherapy.
