Each seminiferous tubule is lined on its inside by two types of cells, called male germ cells $($spermatogonia$)$ and Sertoli cells. The regions outside the seminiferous tubules, called interstitial spaces, contain Leydig's cells. Leydig's cells synthesise and secrete testicular hormones called androgens.

Assertion: A drop in temperature does not affect spermatogenesis.

AnswerCorrect option: A. Both assertion and reason are true, and reason is the correct explanation of assertion.
The normal temperature of the testes in the scrotum is about $2^\circ -2.5^\circ C$ lower than the internal body temperature. When the body is chilled, the smooth muscle contracts and brings the testes closer to the pelvic cavity. This movement towards the pelvic cavity allows the testes to absorb heat from the rest of the body so that the sperm cells do not become chilled and get optimum temperature for spermatogenesis.
