Nipple stimulation

Nipple stimulation is the act of stimulating the nipple, a protruding part of the breast in mammals, either manually or by other means. It is often associated with sexual activity, but can also be a part of non-sexual activity such as breastfeeding or clinical examination.

Anatomy and Physiology

The nipple is a raised region of tissue on the surface of the breast from which, in females, milk leaves the breast through the lactiferous ducts to feed an infant. The nipple is surrounded by the areola, which is often a darker color than the surrounding skin. Nipples can be sensitive to touch due to the presence of nerve endings.

Sexual Stimulation

Nipple stimulation is often an integral part of sexual activity. In both men and women, nipple stimulation can lead to sexual arousal, with the nipples becoming erect and more sensitive. This is due to the release of the hormone oxytocin, which also plays a role in social bonding, sexual reproduction, and during and after childbirth.

Breastfeeding

In the context of breastfeeding, nipple stimulation can help to initiate and maintain the mother's milk supply. The act of a baby suckling at the nipple stimulates the production of oxytocin and prolactin, hormones that support milk production and letdown.

Clinical Examination

Nipple stimulation may also be used in a clinical setting to assess nipple viability and sensitivity, particularly after surgery such as mastectomy or breast augmentation. It can also be used to stimulate labor in pregnant women, as the release of oxytocin can lead to uterine contractions.
