Here's an interesting story I found on the web:
Lactating Man Breastfeeding Baby . . .
Though boys and men have nipples, many are unaware that they also have mammary glands. Usually there is so little mammary tissue that it is unnoticeable. However, if a man develops abnormally large mammary glands (a condition called gynecomastia, aka gyno), it can cause secretion of milk as well. The phenomenon of male lactation in humans has become more common in recent years due to the use of medications that stimulate a man's mammary glands.
Under the appropriate hormonal stimulus, that nature provides to human females when they become pregnant and give birth, the mammary glands of human males can also produce milk. The volume of milk produced is low relative to that of a lactating female. Male lactation is most commonly caused by hormonal treatments given to men suffering from prostate cancer.
Male lactation has, in some cases, commenced without hormonal treatments as well. Extreme stress combined with demanding physical activity and a shortage of food has also been known to cause male lactation. The phenomenon was first studied in survivors of the liberated Nazi concentration camps after World War II. Some American POWs returning from the Korean and Vietnam Wars also experienced male lactation.

Cliffs:
Gynecomastia, known as gyno in the BBing community. is caused by abnormally large male mammary glands.
Certain hormonal conditions, natural or man-made, can take it a step further, so the male mammary glands actually produce breast milk.
Some men with this condition actually breastfeed their children.
Discuss.
