Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → (A) - (II), (B) - (IV), (C) - (I), (D) - (III)
(A) Spermiation — this matches (II) Release of sperms from the seminiferous tubules. After they form, the sperm heads stay embedded in the Sertoli cells. Spermiation is the final step, when the sperms are set free into the tubule.
(B) Sertoli cells — this matches (IV) Provide nutrition to germ cells. These cells line the inside of the seminiferous tubules along with the male germ cells, and they feed the developing germ cells.
(C) Leydig cells — this matches (I) Synthesize and secrete androgens. These interstitial cells lie outside the seminiferous tubules. Under the action of LH, they make the male hormones (androgens), such as testosterone.
(D) Spermiogenesis — this matches (III) Transformation of spermatids into spermatozoa. The round spermatids formed by meiosis change their shape and grow a head, middle piece and tail to become sperms.
