* A variety of sensory receptors detect these cues, including the [[Special_Senses_-_Visual_-_Anatomy_%26_Physiology#Structure|eye]], [[Endocrine_System_-_Pineal_Gland_-_Anatomy_%26_Physiology|pineal gland]] (an organ in the dorsal part of the [[Forebrain_-_Anatomy_%26_Physiology|forebrain]] that is sensitive to light), [[Special_Senses_-_Olfactory_-_Anatomy_%26_Physiology|olfactory organs]], [[Oral_Cavity_-_Tongue_-_Anatomy_%26_Physiology#Taste_Buds|taste buds]], and thermoreceptors.

* The [[Endocrine_System_-_Hypothalamus_-_Anatomy_%26_Physiology|hypothalamus]], located at the base of the brain, is sensitive to signals from sensory receptors and releases [[Hypothalamus_-_Anatomy_%26_Physiology#Outputs|gonadotropin releasing hormones (GnRH)]] in response to environmental cues.
* The [[Hypothalamus_-_Anatomy_%26_Physiology|hypothalamus]], located at the base of the brain, is sensitive to signals from sensory receptors and releases [[Hypothalamus_-_Anatomy_%26_Physiology#Outputs|gonadotropin releasing hormones (GnRH)]] in response to environmental cues.
* GnRH travels from the [[Hypothalamus_-_Anatomy_%26_Physiology|hypothalamus]] to the [[Endocrine_System_-_Pituitary_Gland_-_Anatomy_%26_Physiology|pituitary gland]].
* GnRH travels from the [[Hypothalamus_-_Anatomy_%26_Physiology|hypothalamus]] to the [[Pituitary_Gland_-_Anatomy_%26_Physiology|pituitary gland]].
* Gonadotroph cells of the [[Pituitary_Gland_-_Anatomy_%26_Physiology|pituitary]] receive [[Hypothalamus_-_Anatomy_%26_Physiology#Outputs|GnRH]] and release gonadotropic hormones into the bloodstream.
* Gonadotroph cells of the [[Pituitary_Gland_-_Anatomy_%26_Physiology|pituitary]] receive [[Hypothalamus_-_Anatomy_%26_Physiology#Outputs|GnRH]] and release gonadotropic hormones into the bloodstream.
