Zoology - Human Reproduction Question with Solution | TestHub
Identify A, B, C and D in a given diagram and select the correct statement.
a. A is analogous to the labia majora of female
b. B is a male primary sex organ that produces male gamete and secretes gonadotropic hormones
c. C is a male accessory gland that forms 60-70% of the volume of semen
d. D is also male accessory gland and its secretion helps in activation of sperms
Options:
Answer:
Solution:
In the above diagram,
A = Scrotum, B = testis/testicles, C = seminal vesicle, D = prostate gland
a- Scrotum is analogous to the labia majora in females.
b- Testis is male primary sex organ which produces male gamete and secretes gonadotropic hormones
c- seminal vesicle is a male accessory gland which forms 60%–70% of the volume of semen. Sperm make up only 5 percent of the final volume of semen, the thick, milky fluid that the male ejaculates. The bulk of semen is produced by three critical accessory glands of the male reproductive system: the seminal vesicles, the prostate, and the bulbourethral glands.
d- Prostate gland is also a male accessory gland and it produces prostatic fluid. This acidic fluid makes up about 20%–30% of the semen. It also contains proteins with antibiotic properties that help prevent infections in the male reproductive tract.
