This phrase refers to an old, persistent myth.
From a scientific and anatomical standpoint, breast size has absolutely no correlation with a woman’s intimate anatomy, physical responsiveness, fertility, or health.
External physical traits like breast size are determined by genetics, hormones, and the amount of fatty and glandular tissue in the chest, while a woman’s internal anatomy varies independently. There is no biological rule connecting the two, and ideas suggesting otherwise are entirely based on folklore rather than medical fact.
