ABSTRACT Sex and organs pertaining to sex and sexual activities have been a taboo topic in the Philippines resulting in Filipinos assigning various words to pertain to the topic. Instead of simply saying “titi,” words such as “batuta,” “talong,” and “junior” are used to refer to the male sex or “ari.” This phenomenon also resulted in Filipinos using different body parts to estimate penile length—a taboo topic but casually being talked about in circles. As such, this correlational study discovered whether there is a significant correlation between penile length and somatometric measures such as height, foot size, and hand size. Using quantitative methods, including the researcher acting as the sole gatherer and recorder of body measurements, it is found that penile length and height, foot size, and hand size are positively correlated among 20 Filipino male individuals, ages 20-40, recruited using snowball sampling. Each variable exhibited significant correlation with penile length, both in flaccid and erect states; however, the correlation was with weak coefficient values. The variables with relatively strongest correlation among the data set is shown between erect penile length and height at r = 0.3029, while the weakest correlation is between flaccid penile length and hand size at r = 0.1099. Therefore, while the data set is not generalizable because of the small sample size, there can be a basis in estimating the penile length using the height of an individual.
