      Rare cam be a deceptive term, with the current population of the human race ‘one in a million’ is still 8,000 people.

      But also, male lactation, other than infants at birth who have a high exposure to their mother’s hormones, is always a significant medial concern, so it isn’t something that just sometimes happens.

        Males are born with breast tissue, hence the fact they can get breast cancer.

        One or more hormones (I assume prolactin is involved) are required to activate lactation.
