Male lactation

Male lactation is the production of milk from a male's mammary glands, usually caused by hormonal imbalances or medical treatments. While uncommon, it is possible for men to lactate.

Causes

The primary cause of male lactation is an imbalance of hormones, specifically prolactin. This hormone is responsible for milk production in both males and females. Other causes can include side effects from certain medications, liver disease, kidney disease, or malnutrition. In rare cases, male lactation can be a symptom of a pituitary gland tumor.

Symptoms

The primary symptom of male lactation is the production of milk. This can range from a small amount of clear fluid to a more substantial amount of milk. Other symptoms can include breast enlargement, tenderness, or a lump in the breast tissue.

Treatment

Treatment for male lactation depends on the underlying cause. If the lactation is caused by a hormonal imbalance, treatment may involve hormone therapy. If it is a side effect of medication, the medication may need to be changed. In cases where a tumor is the cause, surgery may be required.
