|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.
|-
|<font color=Purple>Progesterone</font>
|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]].

|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.
|Converted from testosterone, this hormone's function is complex. It may prevent apoptosis of male germ cells.

|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.
|Converted from testosterone, this hormone's function is complex. It may prevent apoptosis of male germ cells.
