Extra nipples, mammary glands are connected with, may be able to produce milk after pregnancy. Sometimes called nipples accessories or third nipples, they often look like moles or freckles and don't always have a connection with fabric ducts or breast milk.Men and women can have an extra nipple. This is a fairly common anomaly that sometimes occurs in families, but is more likely to develop randomly.
Anne Boleyn, wife of King Henry VIII of England, was said to have had a third nipple. Scaramanga, an infamous Bond villain, had an accessory nipple and that was what made it easy to identify. Scientists called the gene Scaramanga after him; is this gene produces a protein called Neuregulin-3 (NRG3), which provides a signal of embryonic cells, telling them to become breast cells.
