(b) Name the organs which produce sperms in human males.
(c) Draw a labelled diagram of the human male reproductive system. With the help of this diagram, describe the working of human male reproductive system?
(d) What is the role of seminal vesicles and prostrate gland in human male reproductive system?

Answer 1

(a) Boys at puberty develop hair in their armpits, chest, face and around the pubic region. They become muscular and their voices crack. Penis and testes become large. The testes begins producing sperms.

(b) Testes produce sperms in human males.

(c) Testes are the primary reproductive organs of human males. They are located in the scrotum outside the body. They produce sperms, which engage into a coiled tube called epididymis and get stored there. Sperms are then carried away through the vas deferens, which joins the urethra. On way to the urethra, sperms also receive secretions from the seminal vesicles and the prostrate gland. The urethra carries sperms to the penis, which opens outside the body.



(d) The seminal vesicles and the prostrate gland produce seminal fluid, which then gets mixed with sperms to form semen.
