Write down the names of three accessory glands of the male sex organ.
Male accessory glands include seminal vesicles (nutrients), prostate gland (enzymes), and Cowper's gland (lubrication).
The three accessory glands of the male reproductive system are:
Seminal Vesicles
These glands produce a significant portion of the fluid that makes up semen. The secretion is rich in fructose, which provides energy for sperm, and other substances like prostaglandins that aid in sperm motility and viability.
Prostate Gland
The prostate gland secretes a milky, alkaline fluid that helps neutralize the acidic environment of the female reproductive tract, enhancing sperm survival and motility.
Bulbourethral Glands (Cowper's Glands)
These are small glands located below the prostate. They secrete a clear, viscous fluid that lubricates the urethra and neutralizes any residual acidity, preparing the pathway for sperm during ejaculation.
These accessory glands work together to produce and support the transport of semen, ensuring the survival and functionality of sperm.
