Breast size is often linked in people’s minds to hormones — especially estrogen — but the relationship is more nuanced than many assume.
Let’s break it down clearly.
🧬 What Determines Breast Size?
Breast size is influenced by:
-
🧬 Genetics (major factor)
-
🧈 Body fat percentage
-
🩺 Hormone levels (mainly estrogen and progesterone)
-
👩 Age and life stage (puberty, pregnancy, menopause)
-
💊 Hormonal medications (e.g., birth control)
Breasts are made of:
