👉 The term "boob fluid" is a colloquial and somewhat outdated medical term that refers to the natural fluid produced by the breast tissue, primarily composed of water, collagen, and various proteins. This fluid plays a crucial role in breast health, contributing to the elasticity and firmness of the breast tissue. During the menstrual cycle, hormonal fluctuations can cause changes in the volume and consistency of this fluid, leading to variations in breast tenderness and fullness. While the term "boob fluid" is not officially recognized in medical literature, it is often used to describe the physiological changes and the natural moisture that occurs in the breasts, reflecting the body's response to hormonal shifts.
