What are the major components of seminal plasma?

Correct Answer

Seminal plasma is the fluid part of semen, formed by the combined secretions of the male accessory glands.

The major components of seminal plasma are the secretions from:

  • Paired seminal vesicles
  • Prostate gland
  • Paired bulbourethral glands

The seminal plasma is rich in fructose, calcium and certain enzymes. These secretions are essential for the maturation and motility of sperms. The seminal plasma along with the sperms constitutes the semen.

Explanation

According to NCERT Biology Class 12 textbook (Chapter 2: Human Reproduction), seminal plasma is formed by secretions from male accessory glands - paired seminal vesicles, a prostate, and paired bulbourethral glands. The text specifically mentions that these secretions are rich in fructose, calcium and certain enzymes. Additionally, the context notes that secretions of epididymis and vas deferens also contribute to sperm maturation and motility. The seminal plasma combined with sperms forms semen.

Solution Steps

  1. Step 1: Identify the male accessory glands from the context - paired seminal vesicles, prostate, and paired bulbourethral glands

  2. Step 2: Extract the composition details - the text states seminal plasma is rich in fructose, calcium and certain enzymes

  3. Step 3: Note the function - these secretions are essential for maturation and motility of sperms
