Question

Which of the components of human semen are correctly matched with the glands that secrete it?
(i) Citric acid - Prostate gland
(ii) Fibrinogen - Seminal vesicle
(iii) Prostaglandins - Prostate gland
(iv) Fructose - Seminal vesicle

• A. i, ii, iii and iv
• B. ii, iii and iv
• C. ii and iv
• D. i, ii and iv

Answer 1

Answer: (D)

Fluid from seminal vesicle contains fructose, vitamin C, prostaglandins and fibrinogen. Fructose is a seminal fluid that provides energy to sperms. Prostaglandins increase the mobility of sperms and stimulate vaginal contractions, which help the infusion of gametes. Fibrinogen helps in the coagulation of semen after ejaculation. The prostatic fluid contains lipids citric acid, enzyme acid phosphatase and proteolytic enzymes. Proteolytic enzymes help in liquefaction of semen.
