Researchers used eye-tracking technology to study how people view female bodies, with some findings suggesting that certain physical characteristics, such as breast size, may be associated with perceived attractiveness and fertility. The study also found that both men and women tend to focus on the nipples when looking at female breasts. However, the specific focus of the study and its findings appear to be somewhat unclear, with reports varying on whether the research examined breast size, overall body evaluation, or other aspects of physical attraction.
