== Nipple erection ==
Nipple erection may result from three kinds of response. It happens in females during [[breast feeding]] or when other suction is applied (e.g. by [[suction bulb]]s). It is also an early part of the sexual response in females and males. Both of these are caused by the release of oxytocin. Nipple erection can also be caused by a tactile response to cold temperature in both males and females. The erection of nipples is not due to erectile tissue, but due to the contraction of smooth muscle under the control of the autonomic nervous system. It is more akin to a hair follicle standing on end than to a sexual erection.
