Question

What is the difference in function between Cowper's gland and the seminal vesicle?

Answer 1

The Cowper’s glands are pea sized glands that sit near the prostate gland in the male reproductive system. The glands produce a fluid that is released before ejaculation that neutralises any urine that may be left in the urethra. The fluid also acts as a lubricant.

The seminal vesicles are two small glands that lie directly above the prostate gland, attached to the vas deferens near the base of the bladder. These glands are very active and make a fluid that makes up about half of the fluid volume of the semen. The fluid produced by the seminal vesicles is rich in fructose (a sugar) that may be important as an energy source for sperm.

Answer 2

$\huge\red{Answer}$

Seminal vesicles are paired glands in male which secrete bulk of the semen (70 to 80%). Vesicles add food for permatozoa in semen, i.e. fructose.

Cowper's glands are also termed bulbourethral glands. Cowper's glands start secreting a sticky, lubricating fluid before actual ejaculation of sperms and semen. The secretion is alkaline, which helps to rinse the acidity from male urethra. Thus secretion from Cowper's glands, helps in penetration by providing lubrication and also offers protection to sperms from acidic environment of male urethra.
