** Ideally, [[Reproductive_Behaviour_-_Copulatory_Behaviour_-_Anatomy_%26_Physiology#Ejaculation|ejaculation]] takes place in a collection cone so that most semen drains directly into the collection vessel.
** Ideally, [[Copulatory Behaviour - Anatomy & Physiology#Ejaculation|ejaculation]] takes place in a collection cone so that most semen drains directly into the collection vessel.
** Surrogate stimulus used to collect semen from the Stallion is referred to as a ''''phantom''''.
** Surrogate stimulus used to collect semen from the Stallion is referred to as a ''''phantom''''.
*** Phantom has a biting belt to provide the stallion with a surface to bite during [[Reproductive_Behaviour_-_Copulatory_Behaviour_-_Anatomy_%26_Physiology#Mounting|mounting]] thus providing a means for natural behaviour.

** It is possible to palpate the urethra at the base of the penis to detect ejaculation. There may also be associated tail movements.

== Electroejaculation ==
* Electrical stimulation of the [[Accessory Sex Glands - Anatomy & Physiology|accessory sex glands]] and the pelvic urethra.
*Used in males of high genetic value that cannot physically perform [[Copulatory Behaviour - Anatomy & Physiology#Mounting|mounting]] and [[Copulatory Behaviour - Anatomy & Physiology#Ejaculation|ejaculation]].
* Electric probe is inserted into the [[Rectum_- Anatomy & Physiology|rectum]] adjacent to the prostate.
* Probe delivers a single electric current of around 15 volts under general anaesthetic.
* Simulates nearby nerves, resulting in contraction of the pelvic muscles and [[Copulatory Behaviour - Anatomy & Physiology#Ejaculation|ejaculation]].
