Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): Androgens stimulate the process of spermiogenesis in the human male. Reason (R): Luteinising hormone (LH) acts on Leydig cells and stimulates the synthesis and secretion of androgens. In the light of the above statements, choose the most appropriate answer from the options given below:
Options
- ABoth (A) and (R) are true and (R) is the correct explanation of (A)
- BBoth (A) and (R) are true but (R) is not the correct explanation of (A)
- C(A) is true but (R) is false
- D(A) is false but (R) is true
Correct answer
D. (A) is false but (R) is true
Step-by-step solution
Assertion (A) is false because androgens stimulate the overall process of spermatogenesis. The specific process of spermiogenesis (the transformation of spermatids into spermatozoa) is aided by factors secreted by Sertoli cells under the influence of FSH. Reason (R) is true because Luteinising hormone (LH) secreted by the anterior pituitary acts on the Leydig cells (interstitial cells) of the testes, stimulating them to synthesise and secrete androgens. Therefore, (A) is false but (R) is true. Answer: (A) is false
