Question

Which hormone stimulates Leydig cells to synthesize and secrete testosterone?

Options

• Inhibin

• FSH (Follicle-Stimulating Hormone)

• LH (Luteinizing Hormone)

• GnRH (Gonadotropin-Releasing Hormone)

Answer 1

Leydig cells, also called interstitial cells, are located in the interstitial spaces between seminiferous tubules. These cells synthesize and secrete testosterone, the primary male sex hormone. The production of testosterone by Leydig cells is stimulated by luteinizing hormone (LH) secreted by the anterior pituitary gland.
