What are the three glands in the human male reproductive system that add secretions to the seminal fluid?
1 Answer
The seminal vesicles, the prostate gland and the bulbourethral glands.
Explanation:
The seminal vesicles are convoluted pouch-like structures about 2 inches in length. They produce the alkaline, viscous component of seminal fluid that is rich in the sugar fructose and other nutrients for the sperm cells and pass it into the ejaculatory duct. These glands produce about 60% of the volume of seminal fluid.
The prostate gland is a single, doughnut-shaped gland. It surrounds
the superior portion of the urethra just below the bladder. It secretes an alkaline fluid that makes up about 13% to 33% of seminal fluid. Its secretion plays a role in activating the sperm cells to swim.
The bulbourethral glands are also known as Cowper’s glands. They are located beneath the prostate gland on either side of the urethra. They secrete thick, viscous, alkaline mucus. This mucus functions as both a lubricant and as an agent to clean the urethra of any traces of acidic urine.
