Which as the function of male accessory gland?
Answers
Answer:
Male accessory glands (MAG) in humans are the seminal vesicles, prostate gland, and the bulbourethral glands (also called Cowper's glands). In insects, male accessory glands produce products that mix with the sperm to protect and preserve them, including seminal fluid proteins.
Answer:
Seminal Vesicles, prostate gland and Cowper's glands are associated with human male reproductive system.
(1) Seminal Vesicles :
i) Seminal vesicles occur in pair present on the posterior side of urinary bladder. Its secretion consists about 60% of the total volume ol the semen.
(ii) The secretion is an alkaline seminal fluid containing iructose, fibrinogen and prostaglandins.
(iii) Fructose helps in the movement of sperms by providing energy to them.
(iv) Semen is coagulated in bolus by fibrinogen. This helps in faster movements of sperms in vagina after inseminatlon.
(v) Reverse peristalsis in vagina and uterus for faster movement of sperms towards the egg in the female body is aided by prostaglandins.
(2) Prostate gland:
(i) It is a single gland located under the urinary bladder. It has about 20 to 30 separale lobes which open separately into the urethra.
(ii) Prostatic fluid secreted by this gland is milky white and sightly acidic. It forms 30 % of the semem and is secreted in urethra.
(iii) Its contents are ciiric acid, acid phosphatase and various other enzymes.
(iv) The sperms are protected from the acidic environment of vagina by acid phosphatase.
(3) Cowper's glands (Bulbo-urethral glands):
(i) Cowper's glands occur in pair on either side of urethra. They are small and pea shaped.
(ii) Cowper's glands secrete an alkaline, viscous, mucous like fuld. It helps as lubricant during copulation.
