Question

Sperm form when ________ stimulates ________ cells to ________ into sperm.

		testosterone; seminiferous; divide
		testosterone; precursor; divide and differentiate
		androgen; precursor; divide and replicate
		androgen; seminiferous; divide and differentiate
		progesterone; precursor; divide

Answer 1

Sperm form when Testosterone stimulates Precursor cells to Divide and differentiate into sperm.

?The process of sperm production is called as spermatogenesis. Here spermatogonia which are precursor cells found in the seminiferous tubules divide and differentiate to produce spermatozoa (sperm). Testosterone is the major androgen which is produced by Leydig cell in response to stimulation of Luteinizing hormone (LH) that will stimulate spermatogenesis.

? Seminiferous cell donot divide to form sperm so options (a) and (d) are incorrect.

? Progesterone inhibits spermatogenesis so option (e) is incorrect.

Thus the correct answer is (b) Testosterone; precursor; divide and differentiate.
