In today’s digital world, myths about body features and health spread rapidly—one of the most common being the belief that breast size reveals details about a woman’s fertility, sexual health, or personality. Scientifically, this claim doesn’t hold up.

While hormones like estrogen do influence breast development, breast size is mainly determined by genetics, body fat, and lifestyle—not reproductive health. Fertility and vaginal health are complex matters shaped by hormonal balance, menstrual regularity, and overall wellness, not the size or shape of any body part.
