* Secretions from the female reproductive tract that serve to sexually stimulate and attract males to the female.

* Vaginal and urinary secretions from females in '''Oestrus''' smell different to the male then secretions of females not in Oestrus.

* Vaginal and urinary secretions from females in [[Oestrus Behaviour - Anatomy & Physiology|Oestrus]] smell different to the male then secretions of females not in [[Oestrus Behaviour - Anatomy & Physiology|Oestrus]].

* Pheramone is a volatile substance released to the outside of the body and perceived by the olfactory system and/or activated by the [[Reproductive_Behaviour_-_Pre-copulatory_Behaviour_-_Anatomy_%26_Physiology#Vomeronasal_Organ|'''vomeronasal organ''']].  Releasing pheramones can cause specific behaviour in the recipient.

* Males also produce sex pheramones.

* Males also produce sex pheromones.

** '''Boars''' produce specific substances that cause sows and guilts to become sexually aroused when they are in '''oestrus'''.

**** During sexual excitement, the boar produces copious quantities of foamy saliva.  The active components in saliva are the androgen metabolites '''3α-Androstenol''' and '''5α-Androstenone'''.  Both have a musk-like odour.
