One reason these myths survive is that people sometimes assume the entire body develops according to one simple pattern.
Breast tissue responds strongly to hormones such as estrogen and progesterone. Genetics and body-fat distribution also contribute to breast size and shape.
Genital anatomy, meanwhile, develops through its own biological processes and varies naturally among individuals.
There is no scientific rule stating that a particular breast size corresponds to a particular genital size or shape.
In other words, looking at someone’s chest cannot provide a reliable measurement or prediction of their intimate anatomy.
