Seminal Plasma

Meaning

Seminal plasma is the complex, non-sperm fluid component of semen, secreted primarily by the accessory glands of the male reproductive tract, including the seminal vesicles, prostate, and bulbourethral glands. This fluid serves a critical physiological role by providing a transport medium, nutritional support, and a protective biochemical environment for spermatozoa. Clinically, its composition is analyzed as a marker of male reproductive tract function and health. The volume and viscosity of this fluid are important parameters in fertility assessment.
