| + | |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. |
