The [[Male Reproductive Tract -The Testes and Epididymis - Anatomy & Physiology|testes]] produce three main [[Endocrine System - Hormones - Anatomy & Physiology|hormones]].

|Leydig Cells
|GnRH from the [[Endocrine System - Hypothalamus - Anatomy & Physiology|Hypothalamus]] causes LH secretion from the [[Endocrine System - Pituitary Gland - Anatomy & Physiology|Pituitary Gland]] which stimulates the Leydig Cells.
|This hormone controls and maintains the growth and functions of the reproductive organs. It enhances libido and is essential for spermatogenesis.

|Sertoli Cells
|GnRH from the [[Endocrine System - Hypothalamus - Anatomy & Physiology|Hypothalamus]] causes FSH secretion from the [[Endocrine System - Pituitary Gland - Anatomy & Physiology|Pituitary Gland]] which stimulates the Sertoli Cells.
|Prevents secretion of further FSH from the [[Endocrine System - Pituitary Gland - Anatomy & Physiology|Pituitary Gland]].
