Semen Formation & Male Accessory Glands — NEET Biology
📚 Practice ConceptSperms released from the seminiferous tubules, are transported by the accessory ducts. Secretions of epididymis, vas deferens, seminal vesicle and prostate are essential for maturation and motility of sperms. The seminal plasma along with the sperms constitute the semen. The functions of male sex accessory ducts and glands are maintained by the testicular hormones (androgens).
Which of the following statements are NOT correct regarding male accessory ducts and glands? S1: The epididymis is the primary site for the temporary storage and maturation of spermatozoa. S2: Seminal vesicles contribute fructose and calcium to the seminal plasma, providing energy and ionic balance for sperm. S3: Secretions from the bulbourethral glands contribute primarily to the fructose and calcium content of the seminal plasma. S4: The prostate gland secretions include enzymes and contribute to a significant portion of the seminal plasma. S5: Vasa efferentia are responsible for the long-term storage of mature sperms before ejaculation.
View solution & NCERT explanation
Correct answer: B — S3 and S5 only
The core concept tested is the specific functions of male accessory ducts and glands in sperm maturation and survival. Evaluating the statements: S1: Correct. The NCERT states that the epididymis and vas deferens store and transport sperms, and secretions of the epididymis are 'essential for maturation and motility of sperms'. S2: Correct. The NCERT states that 'Secretions of these glands [seminal vesicles, prostate, bulbourethral] constitute the seminal plasma which is rich in fructose, calcium and certain enzymes.' Seminal vesicles specifically contribute fructose and calcium. S3: Incorrect. Bulbourethral glands primarily help in 'lubrication of the penis', while seminal vesicles contribute fructose and calcium. S4: Correct. Prostate is one of the accessory glands whose secretions contribute to seminal plasma, which is rich in 'certain enzymes'. S5: Incorrect. Vasa efferentia connect rete testis to the epididymis for transport. Temporary storage and maturation occur in the epididymis and vas deferens, not long-term storage in vasa efferentia. Therefore, S3 and S5 are the statements that are NOT correct.
