Male accessory glands

The male accessory glands include the paired seminal vesicles, the prostate and the paired bulbourethral glands.
Their secretions constitute the seminal plasma, which is rich in fructose, calcium and certain enzymes.
Fructose provides energy to the sperms.
The liver secretes bile, the pancreas secretes pancreatic juice and the salivary glands secrete saliva; none of these is rich in fructose.
Hence the secretions are from the male accessory glands.

The male accessory glands are the paired seminal vesicles, the prostate and the paired bulbourethral glands.
Their secretions together constitute the seminal plasma, which is rich in fructose, calcium and certain enzymes.
Fructose, from the seminal vesicles, is the source of energy for the sperms.
The secretions of the bulbourethral glands also help in the lubrication of the penis.
Hence seminal plasma is rich in fructose and calcium.

The male accessory glands are the paired seminal vesicles, the prostate and the paired bulbourethral glands.
The secretions of these glands constitute the seminal plasma.
NCERT states that the seminal plasma is rich in fructose, calcium and certain enzymes.
Fructose is the energy source for the sperms; the sugar present is not glucose.
Hence seminal plasma is rich in fructose, calcium and certain enzymes.
