The prostate is a walnut-sized gland located between the bladder and the penis, and only appears in males. The prostate is just in front of the rectum. The urethra runs through the center of the prostate, from the bladder to the penis, letting urine flow out of the body1.
The prostate is an important part of the male reproductive system. The prostate contracts during ejaculation and squirts a fluid into the urethra; this fluid is known as prostatic fluid1.
The prostate is an exocrine gland. Exocrine glands secrete through ducts to the outside of the body. The prostate produces a milky-white fluid called the prostatic fluid. Prostatic fluid combines with sperm from the testes, and fluid from the seminal vesicles to form semen. Prostatic fluid comprises approximately 30% of the volume of ejaculatory fluid. Prostatic fluid provides nutrients to sperm, and aids in sperm delivery by protecting them and helping them live longer1.
The prostate also produces a protein called Prostate Specific Antigen (PSA). PSA is released with the ejaculatory fluid and can also be traced in the bloodstream. After ejaculation, PSA makes thickened semen runnier, which helps sperm travel through it more easily1 The amount of PSA that is found in the blood increases with the size of the prostate gland, age and prostate conditions such as BPH, cancer and prostatitis (infection of the prostate)1. There is more information on why this is useful in the following section.
The prostate surrounds the urethra as it passes from the bladder towards the penis and is adjacent to sphincters, which plays a role in controlling urine flow. The prostate may become enlarged and cause urethral compression which can make urination difficult2. The prostate and bladder neck also contract during ejaculation, closing the opening between the bladder and urethra, making it impossible to urinate and ejaculate at the same time1.
