Leydig Cells
Leydig cells are specialized cells located in the testes that produce testosterone, the primary male sex hormone. They play a crucial role in developing and maintaining male secondary sexual characteristics, such as muscle mass, facial hair, and a deeper voice. These cells respond to signals from the brain’s pituitary gland, releasing testosterone during puberty and throughout adult life. Proper function of Leydig cells is essential for male fertility and overall health. They work in balance with other testicular cells to support reproductive function and hormonal regulation in men.
