👉 The mate fluid, also known as seminal fluid, is a complex biological secretion produced by the male reproductive system, primarily composed of seminal vesicle fluid and prostate gland fluid. It serves multiple essential functions, including nourishing and protecting sperm as they travel through the female reproductive tract, enhancing their motility and viability. Additionally, mate fluid contains enzymes that help break down the female reproductive tract's mucus, facilitating easier sperm passage. It also carries fructose, which serves as an energy source for sperm, and various proteins and antibodies that contribute to sperm health and may provide some immunological benefits to the female reproductive system.
