1. the pigmented projection at the tip of each breast; it is smaller in men than women. In women it gives outlet to the lactiferous ducts. Called also mammary papilla, mammilla, and teat.
2. any structure shaped like the nipple of the breast; see papilla.

The nipples are located slightly to the side rather than in the middle of the breasts. Usually, the size of the nipple is in proportion to the size of the breast, but large nipples may be found on small breasts and vice versa.

Surrounding the nipple is a pigmented area called the areola. The color of the areola varies with the complexion. In childless women, it is usually reddish. During pregnancy it increases in size and darkens in color, becoming almost black in brunettes. The color fades after the milk-producing period ends. The tip of the female nipple contains tiny depressions that are openings of the lactiferous ducts. During pregnancy special care should be given the nipples. Any secretion that accumulates should be gently washed off. If the nipples are tender, the physician will advise the use of cold cream, cocoa butter, lanolin, or another emollient to increase their pliability.

Patient discussion about teat

Q. how do i teat my no sperm count? i do not have a live sperm,how can i treat and have live sperm count

A. The treatment is done only at specialist centers, and consists first of evaluation of the reason for this condition (called azoospermia). If an anatomical malformation is found, it may be corrected, as well as medical conditions, and in some cases, direct extraction of sperms from the testes (called MESA) enables in-vitro fertilization.
