Prostatic fluid refers to the fluid that makes up a significant proportion of semen. This fluid is produced by the prostate gland, which is a small gland located close to the bladder in men. There are several synonyms that can be used to refer to prostatic fluid, including prostate secretion, prostatic juice, and prostate fluid. These terms are all used interchangeably to describe the same substance. Additionally, some medical professionals may use the term prostate-specific antigen (PSA) to refer to prostatic fluid, as PSA is a protein that is produced by the prostate gland and found in prostatic fluid. Regardless of the term used, prostatic fluid is an important component of male reproductive health.
