What Causes Nipple Discharge In Men?
It is noteworthy that a lot of men also experience nipple discharge, but due to reluctance or shame, most men tend to ignore the symptoms.
Listed below are the most common causes of nipple discharge in men:
- Hormonal disorders: Deficiency of key male hormones like testosterone often presents with nipple discharge
- Gynecomastia: Excessive growth of breast tissue in males is regarded as gynecomastia. It is often associated with nipple discharge due to excessive glandular growth
- Tumors of pituitary glands: Anterior pituitary gland is responsible for secreting hormones that are responsible for milk secretion. Excessive secretion of certain hormones such as prolactin can also lead to discharge from nipple
- Organic malignancies of breast are also associated with this condition.
It is strongly recommended to see a healthcare professional if you are experiencing discharge from nipple without any obvious explanation.
