What causes nipple soreness in men?

There are several potential causes of nipple soreness in men:

1. Gynecomastia: This is a condition where males develop enlarged breasts due to an imbalance of hormones, such as excess estrogen or low testosterone. Gynecomastia can sometimes cause nipple tenderness or soreness.

2. Hormonal changes: Changes in hormone levels, especially during puberty or certain medical conditions that affect hormone production, may cause nipple soreness or sensitivity.

3. Certain medications: Some medications, such as antidepressants, antipsychotics, or hormone therapy drugs, can have side effects that include nipple soreness or enlargement.

4. Infection: Infections of the breast tissue, nipples, or mammary glands can also cause nipple soreness or pain.

5. Physical injury: Trauma or injury to the chest area, including direct impact or friction, can result in nipple soreness.

6. Paget's disease of the nipple: This is a rare type of breast cancer that begins in the nipple area and may cause redness, soreness, or discharge from the nipple.

7. Underlying medical conditions: Certain medical conditions, such as thyroid issues or liver disease, can affect hormone levels and potentially lead to nipple soreness.

If you're experiencing nipple soreness, it's important to see a healthcare provider for a proper diagnosis to determine the cause and receive appropriate treatment or management. Self-diagnosis and treatment are not recommended.
