Question

Quizplus · Accepted Answer

Sertoli cells play a crucial role in spermatogenesis by providing structural support, producing nutrients for sperm cells, and regulating the process of sperm cell development.

Answer: A
 The process of spermatogenesis takes about three weeks in humans, starting from the production of primary spermatocytes to the release of mature sperm cells.

Answer: B
 Spermatogenesis begins at puberty and continues throughout the life of a male. It does not occur when a male is an embryo, nor does it cease at birth.

Answer: D
 Spermatogenesis occurs within the seminiferous tubules of the testes and is not an event in the epididymis, although the epididymis is where mature sperm cells are stored before they are ejaculated.

Answer: E
 Leydig cells produce and release testosterone, which is required for the development of sperm cells, but the cells do not travel between two closely attached Leydig cells during spermatogenesis.
