Question

Identify the correct option (A), (B), (C), (D) with respect to spermatogenesis.
(1) FSH, Leydig cells, Sertoli cells, spermiogenesis.
(2) ICSH, Interstitial cells, Leydig cells, spermiogenesis.
(3) FSH, Sertoli cells, Leydig cells, spermatogenesis.
(4) ICSH, Leydig cells, Sertoli cells, spermatogenesis.

Accepted Answer

Correct Answer: A — FSH, Leydig cells, Sertoli cells, spermiogenesisStep-by-step Solution:Spermatogenesis is regulated by hormones and involves specific cell types:FSH (Follicle-Stimulating Hormone): Acts on Sertoli cells to promote spermatogenesis.Leydig cells: Produce testosterone under the influence of LH (ICSH).Sertoli cells: Support and nourish developing sperm cells.Spermiogenesis: The final stage where spermatids transform into spermatozoa.Option A correctly lists these components. The order is not strictly sequential but includes key elements. Option B uses ICSH (same as LH) but says "Interstitial cells, Leydig cells" – redundant. Option C has Sertoli cells before Leydig cells. Option D has ICSH, Leydig cells, Sertoli cells, spermatogenesis – but spermatogenesis includes spermiogenesis. However, the official answer is A.Key Concepts: Spermatogenesis: hormonal control (FSH, LH/ICSH), roles of Leydig cells (testosterone) and Sertoli cells (nourishment), stages (spermatogenesis, spermiogenesis).
