More porn, worse erectile function

A study has shown that the amount of porn a man watches is linked to worse erectile function. Watching porn is also associated with greater dissatisfaction with "normal" sex, with only 65% of respondents rating sex with a partner to be more stimulating than porn. This work is presented at the EAU virtual Congress.

Pornography has been increasingly available via the internet since around 2007. This has led to a rapid uptake in use, but there is little information on how increasing porn use might affect erectile function. Researchers from Belgium, Denmark and the U.K. established an online questionnaire, which was advertised mainly to men in Belgium and Denmark through social media, posters and flyers. 3,267 men replied to the 118 questions, answering questions about masturbation, frequency of porn watching, and sexual activity with partners. The questionnaire concentrated on men who had had sex within the previous four weeks, which allowed the team to relate the effect of porn watching on sexual activity. The questionnaire incorporated questions from standard erectile function and sexual health surveys.

Head researcher Professor Gunter de Win of the University of Antwerp and University Hospital Antwerp said, "We found that there was a big range of responses. In our sample, men watch quite a lot of porn, on average around 70 minutes per week, normally for between five and 15 minutes per time, with obviously some watching very little and some watching much, much more."

They also found that around 23% of men under 35 who responded to the survey had some level of when having sex with a partner. Professor de Win said, "This figure was higher than we expected. We found that there was a highly significant relationship between time spent watching porn and increasing difficulty with erectile function with a partner, as indicated by the erectile function and sexual health scores. People who watch more porn also scored high on porn addiction scales. We need to understand what this work means and doesn't mean. It is a questionnaire rather than a clinical trial, and it could be that the people who have responded are not completely representative of the whole male population. However, the work was designed to unpick any relationship between porn and erectile dysfunction, and given the large sample size, we can be pretty confident about the findings."

He continued, "We found that 90% of men fast-forward to watch the most arousing pornographic scenes. There's no doubt that porn conditions the way we view sex; in our survey, only 65% of men felt that sex with a partner was more exciting than watching porn. In addition, 20% felt that they needed to watch more extreme porn to get the same level of arousal as previously. We believe that the erectile dysfunction problems associated with porn stem from this lack of arousal. Our next step in this research to identify which factors lead to erectile dysfunction, and to conduct a similar study on the effects of porn on women. In the meantime, we believe that doctors dealing with erectile dysfunction should also be asking about watching pornography."

Professor Maarten Albersen of the University of Leuven, Belgium, who was not involved in conducting the study, said, "This is an interesting study by Prof. De Win and colleagues. The sample consisted mainly of younger men recruited via and posters, which may result in a sample biased toward higher online porn consumption rates. All-in-all, the study raises interesting insights, in the fact that porn consumption by men may lead to impaired erectile function and/or sexual satisfaction or confidence during partner-sex. As Professor De Win says, the running hypothesis is that the type of porn watched may come more explicit over time, and partner sex may not lead to the same level of arousal as the pornographic material does. The study contributes to an ongoing debate on the topic; experts have highlighted that porn may have both positive and negative effects, and could, for example, be used as an aid in the treatment of sexual dysfunctions, so this is a controversial area and the last words have not been said on this topic."
