Question

Seminal vesicles are located in
(a)Caput epididymis
(b)Uterus
(c)Above Cowper’s glands
(d)Glans penis

Answer 1

Hint: Seminal vesicles are the largest male sex glands. Accessory glands are glands that are not involved in gamete formation directly but instead help the primary sex gland in the formation of gametes by providing nutrition, lubrication, etc.

Complete Answer:
Seminal vesicles are located above the bulbourethral glands or Cowper glands. Seminal vesicles are part of the male accessory organs and release a viscous fluid rich in fructose to provide energy to the sperms, prostaglandins which help in motility and function of sperms, and proteins that keep the sperms coagulated after ejaculation. The prostate gland is a walnut-sized gland that is located between the bladder and the penis. The prostate secretes fluids into the urethra to nourish and protect the sperms. The bulbourethral gland is paired, small, pea-shaped which is located under the prostate gland. It releases fluids that provide lubrication for the act of copulation.

Additional information:
Let us look at the male reproductive structure in detail.
-The male reproductive structure consists of two primary sex organs known as the testes, accessory glands, ducts, and external genitalia.
-The testes are found inside a sac known as the scrotum which is present outside the abdomen. The scrotum is present outside to ensure a temperature of 1-2 degrees less than the body which is essential for sperm production.
-Each testis has 250 parts known as testicular lobules. And each testicular lobule has 1-3 seminiferous tubules in it which have two types of cells known as spermatogonia and Sertoli cells.
-The interstitial space between the seminiferous tubules has Leydig cells which are responsible for the synthesis of male testicular hormones known as androgens.

So, the correct option is ‘Above Cowper’s glands’.

Note:
-The fluid that consists of the secretive juices from the male accessory glands and the sperms is known as seminal fluid or semen.
-The external genitalia of males is known as the penis and it is made up of special connective tissue that helps in its erection.
-The spermatogonia cells undergo meiosis to produce sperms whereas the Sertoli cells are responsible for providing nourishment to the sperms.
