Question

Function of prostate gland is to-
a. Store semen
b. Provide motility to sperms
c. Form semen
d. Release hormones

Answer 1

Hint: The prostate gland is a chestnut-shaped gland situated between the bladder and penis in males. The vasa deferentia bear sperm from the testes on the way to the seminal vesicles. The prostate is to be found immediately in front of the rectum. The seminal vesicles give fluid to semen throughout ejaculation.

Complete answer:
The main purpose of the prostate gland is to emit an alkaline fluid that involves approximately 70% of the seminal volume. The secretions make lubrication and nourishment for the sperm. The alkaline fluid in the ejaculate leads to liquefaction of the seminal plug and aids to balance the acidic vaginal environment. The main function of the prostate gland is to provide motility to the sperms.

Its emission provides food and shield to the sperms. The muscles of the prostate gland also help in impelling the seminal fluid into the urethra for the period of ejaculation. Its discharge constitutes about one-third of the amount of semen and contains different enzymes, zinc, and citric acid.

Hence, the correct answer is option (B).

Note: The prostatic urethra is a medium for semen and stops retrograde ejaculation by closing off the bladder neck in the climax. Ejaculation involves a synchronized narrowing of many different components, counting the smooth muscles of the seminal vesicles, vasa deferentia, ejaculatory ducts, etc. The urethra runs throughout the center of the prostate, from the bladder to the penis, leasing urine flow out of the body. The prostate secretes fluid that nurtures and protects sperm. During ejaculation, the prostate compresses this fluid into the urethra and it’s barred with sperm as semen.
