Either you never read it or you did and you're just lying. I've posted
the Proksch data frequently.

I'll repeat it and add some.

   Penile HPV-associated lesions are frequently seen in male sexual
partners of women with CIN. The natural course and clinical
significance of these lesions are unclear. Women with CIN and their
male sexual partners were randomized for condom use (condom group n =
68, noncondom group n = 68). Males were screened for the presence of
penile lesions, i.e., flat lesions, papular lesions and condylomata
acuminata, and of HPV in their penile swabs by PCR testing. Median
follow-up time was 13.1 months (range 2.9-57.4). The outcome of our
study was clinical regression of penile lesions defined as
disappearance of lesions at penoscopy. Potentially prognostic factors,
i.e., HPV status, lesion type and age, were studied as well. Outcomes
were assessed in 57 men of the condom group and in 43 men of the
noncondom group. Condom use shortened the median time to regression of
flat penile lesions (7.4 months condom group vs. 13.9 months noncondom
group; HR = 2.1, 95% CI 1.2-3.7). This effect was not found for
papular lesions (HR = 0.5, 95% CI 0.1-2.8). HPV-negative men showed a
significantly shorter median time to regression of flat lesions (3.8
months) compared to men with either HPV-positive status (8.5 months;
HR = 0.4, 95% CI 0.2-0.9) or inconsistent HPV status (13.1 months; HR
= 0.2, 95% CI 0.1-0.6). Regression of flat penile lesions is
HPV-dependent and accelerated by condom use. This effect is probably
the result of blocking viral transmission between sexual partners.

As we move further into the 21st century, there are increasing numbers
of teenagers and young adults infected with sexually transmitted
diseases and acquired immunodeficiency syndrome. Aside from sexual
abstinence, condom use is the best way to protect oneself from
sexually transmitted diseases, including human immunodeficiency
virus/acquired immunodeficiency syndrome. Participants in this study
were predominantly female, predominantly Caucasian psychology students
who experienced sexual intercourse with an opposite sex partner in the
past year. Slightly fewer than half of these participants reported
condom use at their last episode of vaginal intercourse and type of
partner did not affect their condom use, nor did concern about human
immunodeficiency virus/acquired immunodeficiency syndrome and sexually
transmitted diseases. Findings such as these challenge advanced
practice nurses to generate innovative strategies to promote condom
use in all types of relationships. We propose that teaching about the
link between cervical cancer and lack of condom use could be one of
these new strategies.

BACKGROUND: Although condoms most likely prevent HIV infection,
evidence of their effectiveness against other sexually transmitted
diseases is mixed. GOAL: The goal of the study was to determine
whether condom use prevents genital human papillomavirus (HPV)
infection and HPV-related conditions. STUDY DESIGN: We conducted a
literature review and meta-analysis of the effect of condom use on the
prevention of genital warts, subclinical HPV infection, cervical
intraepithelial neoplasia (CIN), and invasive cervical cancer (ICC).
RESULTS: Among 27 estimates from 20 studies, there was no consistent
evidence that condom use reduces the risk of becoming HPV
DNA-positive. However, risk for genital warts, CIN of grade II or III
(CIN II or III), and ICC was somewhat reduced. CONCLUSIONS: Available
data are too inconsistent to provide precise estimates. However, they
suggest that while condoms may not prevent HPV infection, they may
protect against genital warts, CIN II or III, and ICC.

No risk from nitrosamine content in condoms.

Volatile N-nitrosamines have been found in rubber products including
gloves, balloons, toys, baby bottle teats, soothers, and condoms.
N-Nitrosamines are potent carcinogens, and therefore, European
legislation has limited the release of N-nitrosamines and
N-nitrosatable compounds in teats and soothers to 0.01-0.1 mg/kg
rubber, respectively. Previously, endogenous nitrosamine formation in
the vagina has been suggested as a cause of cervical cancer. It was
speculated that exogenous N-nitrosamines and N-nitrosatable compounds
from condoms may also lead to genital cancer. Therefore, we reviewed
the literature and calculated the risk for the induction of tumors by
nitrosamines from condoms. In vitro Biaudet et al. (1997) found up to
88 ng nitrosatable compounds migrating from condoms to cervical mucous
within 24 hrs. During sexual intercourse about 0.6 ng may migrate in
the female genital mucous membranes because of the short contact to
the condom, e.g. 10 min. Comparable amounts of nitrosamines may also
migrate in the penile skin. Estimating 1500 contacts to condoms during
lifetime (50 condoms/year for 30 years) this may result in the
adsorption of up to 0.9 microgram nitrosamines in total. Animal
studies in Syrian hamsters showed the induction of local and/or
systemic tumors, in particular liver tumors, after topical application
of nitrosamines to the skin or mucous membrane at a total dose of
about 1 g. This dose exceeds the dose to be expected from contact with
condoms by more than 1 million. Also, epidemiological studies do not
support a role for condoms in the induction of cancer. The incidence
of cervical cancer and liver tumors is high in developing countries,
where condoms are seldom used. In addition, humans are regularly
exposed to nitrosamines from food and tobacco smoke at a dose which is
1,000 to 10,000 fold higher than expected from condom use. In summary,
the risk for the induction of tumors from nitrosamines in condoms is
very low.
