Question

Testosterone is produced by

• A. Cells of Malpighi
• B. Sertoli cells
• C. Spermatogonial cells
• D. Leydig cells

Answer 1

The correct option is D

Leydig cells

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 small blood vessels and interstitial cells or Leydig cells. Leydig cells synthesise and secrete testicular hormones called
androgens (testosterone).
