Leydig Cells

Leydig cells are rounded (polygonal) cells of the testicular interstitium with a centrally located nucleus and eosinophilic cytoplasm. Their main function is the production of male sex hormones, mainly testosterone. Their function is influenced by the luteinizing hormone of the anterior lobe of the pituitary gland.

Leydig cells can also rarely appear in women as part of the so-called ovarian Sertolli-Leydig tumor.
