Question

Which gland of the male reproductive system provides sugar/fructose for sperm motility?
A. Seminal vesicle
B. Prostate
C. Cowper’s
D. Tyson’s

Answer 1

Hint: Male reproductive glands produce the seminal fluid which composes semen along with sperms. Seminal fluid is responsible for nourishment and facilitation of movement of sperms.

Complete answer:
Option A: Seminal vesicles are a pair of accessory glands in the male reproductive system. They are coiled and folded tubular structures present below the urinary bladder. These glands contribute significantly to the seminal fluid. Seminal vesicles secrete nutrients such as fructose, citric acid, etc which helps the sperm movement. Therefore this is the correct answer.

Option B: Prostate gland is a male reproductive system accessory gland present below the bladder. They secrete a white milky fluid which is a part of semen. These fluids are alkaline in nature and this helps to counter and neutralize the acidic nature of the female reproductive tract and protect the sperms. Prostate fluid also contains proteolytic enzymes and fibrinolysis. Therefore, this is the incorrect option.

Option C: Cowper's gland is an exocrine gland of the male reproductive system. They are present beneath the prostate gland. They produce pre-ejaculate fluid which lubricates urethrae and facilitates the transport of sperms. They also neutralize the acidic nature of the urethra which is a result of micturition. Therefore, this is the incorrect option.

Option D: Tyson's gland or preputial glands are found on the foreskin of the penis. They are modified sebaceous glands in human males and produce pheromones in some other animals. Therefore, this is the incorrect option.

Hence, the correct answer is option (A)

Note: 1.Fructose serves as the energy source for the movement of sperm.
2.Seminal vesicles also secrete prostaglandin which reduces the thickness of the cervix wall. 3.Seminal vesicles produce 60% of semen.
