The term "phallology" refers to the study of the penis in its various aspects. However, as it is a relatively rare and specialised term, there are not many commonly used synonyms for it. One possible term which is occasionally used is "phallic studies", which can include not only the anatomical aspects of the penis, but also the symbolic and cultural meanings attached to it. Another synonym could be "penile studies", which focuses more exclusively on the physical characteristics and functions of the penis. These terms are not frequently used in general discourse, but are more likely to be found in academic or medical contexts.
