• A prospective study on supernumerary nipples (SNNs) was performed on 1,691 consecutively born neonates. We used a new technique for easier routine detection of SNNs. The incidence of this anomaly was one per 40 or 25 per 1,000 live births. Association of other congenital abnormalities with SNNs was not found.
