Male sexual Health Study and Sexting


Male sexual health study



The male sexual health study was an international cross-sectional study conducted by the university of Antwerp. It’s primary goal was to see if they could find a correlation between porn consumption and erectile dysfunction. A 118-item questionnaire was published on The study was registered on (id 5111).  Data were collected between April 2019 and May 2020. 5770 men responded. Validated questionnaires like Cyber Pornography Addiction Test (CYPAT), IIEF-5, MSHQ-ED, and Porn Craving Questionnaire (PCQ) were included. Estimated amount of porn watching was calculated. CYPAT is composed of 11 items scored on a five-point Likert scale to screen for porn addiction. Higher scores (minimum=11, maximum=55) indicate more problematic addictive behavior.


This study found that 80% of participants below 26 started watching porn when they were 13 or younger. 84 percent of them masturbated more than once a week (43,5% daily) and 72,1 percent of them used pornography 7 to 10 times out of 10 masturbation sessions. The CYPAT score for  younger participants shows significant more ED (with partnered sex) with higher CYPAT scores (up to 35% for a CYPAT score 26-30 and up to 55% for a CYPAT score of 31 or higher) (see figure 2).  Furthermore, already 12% of young people under 26 have a CYPAT score higher than 26. Only 65% of participants rated real sex as more arousing than pornography.


52% of participants who had ED during sex with a partner, did not suffer ED during masturbation with porn.  However, in this 52% of participants with ED during partnered sex, only 25% did not suffer ED while masturbating without porn.

The preliminary results were presented at the American Association of Urology, Annual Conference (may 2020) and the European Associaton of Urology (Annual Conference, July 2020) and received media attention in more then 140 countries.

Sexting research by research group MIOS, University of Antwerp

Several studies by the research group MIOS have pioneered research on sexting, the sending and receiving of self-made sexually explicit images through the Internet and the mobile phone. Sending is a digital form of sexual communication. In the most recent study, it was found that 9.3% of Flemish teenagers between 12 and 18 years old has sent a sexting picture of themselves (Van Ouytsel, Walrave, De Marez, Vanhaelewyn, & Ponnet, 2020).

While sexting is a normative behavior within adolescence, it can be regarded as risky because the images can lead to bullying and can have serious consequences. While sexting is different than pornography use, both may also be related. Sexting may also be a result of a very visual media environment, in which sexual images can be easily accessed, viewed and shared by young people. For example, one study by MIOS researchers found that youth who consume pornography are also more likely to engage in sexting and ask others to send sexts of themselves. Pornography culture may contribute to normalization of sexting behaviors (Van Ouytsel, Ponnet, & Walrave, 2014)
