Many people are unaware that breast size can sometimes provide subtle clues about a woman’s reproductive health. This doesn’t mean there’s a direct or guaranteed link, but certain biological connections have been observed in scientific research.
It’s a widespread myth that larger breasts automatically indicate higher fertility or better sexual function. While that idea might sound compelling, the truth is far more complex and grounded in a mix of genetics and hormones.
Breast size is primarily determined by genetic inheritance and overall body fat distribution. However, hormones—especially estrogen—also play an influential role in breast development during puberty and adulthood.
