Recent research is Sexual behavior archives Artificial intelligence has revealed that it can generate erotic images of women that viewers find more beautiful and sexually appealing than photos of actual humans. Although people still perceive real photos to look more authentic, fabricated images definitely score higher on measures of attractiveness and overall comfort. These results suggest a remarkable shift in how digital technology may alter human perceptions of physical beauty and sexual attractiveness.
Lead researcher Ellen Zakreski, a scientist at the Czech National Institute of Mental Health and Charles University, collaborated with colleagues to investigate contemporary perceptions of visual sexual material. The researchers conducted this study because expectations about erotic images are changing across generations. Images that researchers validated for psychological tests decades ago often fail to elicit the same responses from young adults today.
Humans have been creating visual sexual material for thousands of years. Early examples range from ancient cave paintings and fertility statues to vintage pornographic magazines. Today, with the advent of the Internet, the availability and variety of digital sexual media has exploded.
Viewers now have instant access to relatively realistic depictions of sexual acts as well as highly stylized and fantasy-filled content. This modern media environment includes artificial intelligence and computer-generated images. These digital tools allow creators to construct highly realistic three-dimensional images of people who don’t actually exist.
While traditional plastic surgery can change the appearance of a real person, digital programs give creators complete control over every detail of their bodies. Artificial intelligence in particular can generate hyper-realistic images with incredibly sharp visual resolution. This technology can alter real photos by changing a person’s body shape, facial features, and hair color.
You can even create a completely new person from scratch. In addition, modern viewers often come across images of real women who have undergone surgery to enlarge their lips, breasts, and hips. Other distinct categories of sexual media include life-like silicone sex dolls and hentai.
Hentai is a pornographic form of Japanese comic art characterized by highly exaggerated physical proportions and fantasy elements. With hyper-realistic sexual images now widely accessible, viewers may have a hard time distinguishing between real photographs and digital works. Zakreski and his colleagues wanted to understand how people respond to these different visual styles.
To explore these contemporary visual categories, researchers conducted a nationwide online survey in the Czech Republic. They recruited 649 adults who self-identified as sexually attracted to women. Although most of the participants consisted of men, a small group of 45 women also completed the survey.
During the experiment, participants viewed a static image of a naked woman presented on a neutral gray background. The researchers showed volunteers images from six different categories. These categories included real photos of real women, computer-generated figures, figures created by artificial intelligence, surgically enhanced real women, silicone sex dolls, and hentai illustrations.
To account for different individual preferences, the researchers ensured that each of the six categories included five different personality types. These numbers varied by hair color, from blonde to black. They also featured a variety of body types, including voluptuous, athletic, and petite.
The team purchased basic three-dimensional digital templates and refined them to create computer-generated shapes. We then searched for real photos, sex doll images, and hentai illustrations that closely matched the poses and body types of those digital models. We also used an online artificial intelligence platform to generate matching numbers through specific text prompts.
After selecting the images, the team used photo editing software to standardize the visuals. They removed distracting elements such as tattoos and jewelry. We also matched skin tones across all categories to ensure that they look like the original computer-generated figures, ensuring a level of visual consistency.
Participants rated each image’s realism, sexual appeal, and aesthetic appeal from 0 to 100 using a digital slider scale. They also rated the emotional pleasantness of each image (a concept scientists call valence) using a standard five-point picture scale. The researchers randomized the order of the images to prevent serial bias.
This picture scale used simple cartoon numbers to measure emotional responses. This helped participants indicate whether the image made them feel “unhappy, irritated, dissatisfied, depressed, hopeless, or bored” or “happy, satisfied, satisfied, hopeful, or relaxed.” Participants selected the cartoon figure that best matched their emotional response.
When the researchers reviewed the data, they found that participants rated real photos as the most realistic category. In terms of realism, artificial intelligence images took second place. Computer-generated figures, surgically enhanced women, sex dolls, and hentai illustrations followed in descending order of perceived realism.
Despite being considered less realistic than real photographs, images generated by artificial intelligence ranked highest in terms of aesthetic appeal. Participants also rated the artificial intelligence figures as the most sexually attractive and the most emotionally pleasing. Actual photos ranked second across these three metrics.
Images of surgically enhanced women received the lowest ratings for aesthetic appeal and overall comfort. Erotic illustrations and images of sex dolls also rank low in these categories. Most participants found these unrealistic categories to be somewhat unpleasant overall.
This study revealed clear differences in how men and women evaluate images. Men generally gave higher ratings in all categories: realism, attractiveness, aesthetic appeal, and comfort. Women found the images to be less attractive and realistic overall, but their overall category rankings were consistent with the pattern seen for men.
Age also played a large role in how participants perceived different categories. Older adults tended to give higher aesthetic and sexual attractiveness ratings to real photos, artificial intelligence images, and computer-generated figures. Younger participants also found these realistic categories to be more emotionally pleasurable.
Conversely, younger participants had a much more favorable reaction to the hentai illustrations. They rated these stylized cartoons as more aesthetically beautiful, sexually appealing, and emotionally pleasing than older participants. Researchers suggest that younger generations are more exposed to Japanese comic art styles in mainstream media, which may be normalizing their aesthetic.
The researchers note that these age-related differences highlight how early exposure to certain types of media shapes long-term visual preferences. Older people may have grown up seeing pictures of natural women in magazines. Young people have grown up in an era saturated with digital manipulation and highly stylized animation.
The research team acknowledged some limitations in their experimental design. The sample of participants included far more men than women, making it difficult to draw broad conclusions about women’s preferences. Furthermore, this recruitment method targeted individuals already registered in the sexuality research database.
This database included people participating in an outreach program for atypical sexual interests, so the sample may not fully reflect the general public. Another limitation involves the physical characteristics of the images used in the study. All female figures featured lighter skin tones, in keeping with the general ethnic demographics of the Czech Republic.
The researchers also had to rely on existing images for some categories. This limitation resulted in minor inconsistencies as some figures had different facial expressions, hand placement, and hairstyles. This study also relied entirely on subjective self-reports rather than objective physiological measurements.
The researchers did not track physical signs of sexual arousal, such as heart rate or blood flow. Future research could incorporate these physiological indicators to see if the human body responds differently to real photographs and digital works. The authors recommend that future research expand the types of visual stimuli.
They suggest creating image sets that feature diverse ethnic backgrounds and different age groups. Expanding the study to include images of naked men could also help reveal whether this preference for images of artificial intelligence also applies to people who are attracted to men. As digital technology continues to advance, artificial intelligence will likely produce more convincing and stylized erotic media.
The study, “Subjective responses of male and female female lovers to real and artificial female nudity,” was authored by Ellen Zakreski, Alena Malečková, Ondrze Vanicek, Martin Hula, Kateřina Krapirova, Zytka Lindová, and James G. Pfaus.
