Prostasomes are submicron, membrane-surrounded organelles produced by the epithelial cells of the human prostate gland and are present in appreciable amounts in normal human semen. The prostasomes are ascribed many functional effects. They have an immunosuppressive capacity by inhibiting the lymphoproliferation and the phagocytosis of macrophages. The prostasomes also regulate the complement activation. They possess an antioxidant capacity. The prostasomes are also able to attach onto washed, prostasome-free spermatozoa and promote the forward motility of the sperm cells.
前列腺小体是由人类前列腺上皮细胞产生的亚微米级、被膜包围的细胞器，在正常人类精液中含量可观。前列腺小体具有多种功能作用。它们通过抑制淋巴细胞增殖和巨噬细胞的吞噬作用而具有免疫抑制能力。前列腺小体还能调节补体激活。它们具有抗氧化能力。前列腺小体还能够附着在经过洗涤且不含前列腺小体的精子上，并促进精子细胞的向前运动。
