Questions and Answers

What is the primary reason for conducting seminal fluid analysis?

  • To analyze the viscosity of semen
  • To evaluate the presence of fructose in the seminal fluid
  • To determine the acidity of the seminal fluid
  • To assess infertility (correct)
  • Which gland contributes to about 60% of the fluid in seminal vesicles?

  • Epididymis
  • Bulbourethral gland
  • Seminal vesicles itself (correct)
  • Prostate gland
  • What is the role of fructose in seminal fluid?

  • It aids neutralization of fluid with thick alkaline mucus
  • It contributes to the acidic fluid content in the prostate gland
  • It is a source of energy for sperms and needed for sperms motility (correct)
  • It adds carnitine and acetylcarnitine to the lumen fluid
  • What does the pH of prostatic secretion help to achieve?
