Male lactation

Male lactation is when a man can produce milk from his chest. It is very rare, and usually only happens when a man's body produces hormones that are usually only found in mothers who are breastfeeding. This can be caused by some medical conditions, or medications that a man takes. Male lactation is not something that happens very often, but if it does happen, it is possible for a man to breastfeed a baby.
