👉 The blond fluid, also known as pre-epithelial fluid or pre-ejaculate, is a clear or slightly yellowish liquid that some men produce before ejaculation. It originates from the ducts leading to the penis and is primarily composed of water, proteins, lipids, and various enzymes. This fluid serves several functions: it helps to nourish and prepare the sperm for potential fertilization, acts as a protective barrier against infections, and contributes to the overall lubrication of the reproductive tract. The presence of enzymes like prostate-specific antigen (PSA) and lactoferrin in the blond fluid also aids in maintaining a healthy environment for sperm.
