Read the passage below and answer the following question.
The male reproductive system is located in the pelvis region. The testes are situated outside the abdominal cavity within a pouch called scrotum. The testis is covered by a dense covering. Each testis has about 250 compartments called testicular lobules. Each lobule contains one to three highly coiled seminiferous tubules. Each seminiferous tubule is lined on its inside by two types of cells called male germ cells and Sertoli cells. The regions outside the seminiferous tubules are called interstitial spaces. Leydig cells synthesise and secrete testicular hormones called androgens. The male sex accessory ducts include rete testis, vasa efferentia, epididymis and vas deferens. The seminiferous tubules of the testis open into the vasa efferentia through rete testis. The vasa efferentia leave the testis and open into epididymis located along the posterior surface of each testis. The epididymis leads to vas deferens that ascends to the abdomen and loops over the urinary bladder. Secretions of accessory glands constitute the seminal plasma which is rich in fructose, calcium and certain enzymes. The secretions of bulbourethral glands also helps in the lubrication of the penis.
The male reproductive system includes which of the following?
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → All of the above
The male reproductive system lies in the pelvis region. It is made of a pair of testes, the accessory ducts, the accessory glands and the external genitalia, so each of the three listed parts belongs to it.
Option (1) Testis — Correct statement, but it is only one of the correct points, so on its own it is not the answer. The testes are the primary sex organs of the male; they produce sperms and the hormones called androgens.
Option (2) Accessory ducts — Correct statement, but it is only one of the correct points, so on its own it is not the answer. Rete testis, vasa efferentia, epididymis and vas deferens store and carry the sperms.
Option (3) External genitalia — Correct statement, but it is only one of the correct points, so on its own it is not the answer. The penis is the male external genitalia; it is made of special tissue that helps in erection.
NCERT Extract:
The Male Reproductive System – “The male reproductive system is located in the pelvis region (Figure 2.1a). It includes a pair of testes alongwith accessory ducts, glands and the external genitalia.”
The Male Reproductive System – “… The penis is the male external genitalia (Figure 2.1a, b).”
