Question

The semen fluid consists of sperm cells and it is secreted from
A. Seminal vesicle
B. Cowper gland
C. Prostate gland
D. All of the above

Answer 1

Hint: All living beings evolve through reproduction. Reproduction allows a species of organism to keep growing in number and to keep their species alive. This is one of the only body systems of an organism that keeps its species alive and not necessarily the individual alive.

Complete answer: The sex organs required for reproduction in the male reproductive system include the penis, testicles, scrotum, and accessory glands. The accessory glands include the seminal vesicles, the prostate gland, the bulbourethral glands, otherwise also known as the cowper glands. The penis consists of two parts, a shaft, and the glans. The shaft is the main part of the penis, whereas the glans is the tip, also known as the head, of the penis. A small slit at the end of the glans allows the excretion of urine through the urethra and ejaculation of semen during sexual intercourse. The three glands are as follows-
a. Seminal vesicles: These are sac-like pouches closer to the base of the bladder where they are attached to the vas deferens. The seminal vesicles provide energy to the sperm, helping its ability to move by the production of a fluid rich in sugar (fructose). Most of the man’s ejaculatory fluid, or ejaculate, or semen is made up of the fluid of the seminal vesicles.
b. Prostate Glands: The prostate gland makes up the additional fluid to the man’s ejaculatory fluid, or ejaculate, or semen apart from the seminal vesicles. The sperm is also supplied with nourishments from the prostate fluids. The prostate gland is located in front of the rectum, below the urinary bladder. It is a walnut-sized structure.
c. Bulbourethral glands: The bulbourethral glands are also known as the Cowper’s glands. They are pea-sized in structures. They are located just below the prostate gland. These glands produce a fluid that lubricates the urethra. It is a clear slippery fluid that also neutralizes the acidity that could have been caused by the residual drops of urine in the urethra.
Hence, Option A, i.e., Seminal vesicles, is the correct answer.

Note: A seminogram which is also known as semen analysis is conducted to evaluate the characteristics of the semen and the sperm cells present in it. This analysis assists in the evaluation of male fertility for those who are willing to get pregnant and/or to verify the success of vasectomy.
