This is an important point because myths about genital appearance have historically been used to judge or shame women.
Scientific understanding of human anatomy shows that such assumptions are unreliable.
The body is not a record of someone’s personal history.
Breast size also has no reliable relationship with fertility.
Having larger or smaller breasts does not automatically mean that a woman is more or less fertile.
Fertility depends on many factors involving reproductive organs, hormones, ovulation, age, genetics, overall health, and other biological circumstances.
Similarly, breast size does not determine whether someone will have difficulty becoming pregnant or whether they will experience pregnancy normally.
Pregnancy and breastfeeding can change breast size and appearance, but these changes occur because of hormonal and physiological processes rather than because breast size predicts another part of the reproductive system.
Another reason the myth persists is that people sometimes confuse sexual attractiveness with biological function.
