That statement is a myth—there’s no scientific or medical link like that.
A woman’s breast size is mainly influenced by:
- Genetics
- Body fat percentage
- Hormones such as Estrogen
It does NOT indicate anything about her “inner parts”, whether that means:
- Reproductive organs (uterus, ovaries)
- Sexual anatomy
- Fertility or health
- Personality or character
All of those are completely independent of breast size.
If you were referring to a specific “inner part” (for example anatomy, health, or something else), clarify and I’ll explain it accurately.
