Prolactin Deficiency in Men

Prolactin, also known as the milk hormone, is secreted by the pituitary gland in both men and women but at different levels. Women, especially during pregnancy, produce much higher amounts due to its vital role in childbirth and lactation. In men, elevated prolactin levels can cause sexual dysfunction, temporary infertility, reduced testosterone production, and decreased libido. Conversely, a significant deficiency in prolactin can lead to various sexual, psychological, and health problems.

Functions of Prolactin

Prolactin serves several important roles in the body, including:

• Regulating water and salt balance within the body.
• Supporting immune system function.
• Stimulating milk production in women during pregnancy and after childbirth.
• Contributing to the formation of the lung lining fluid in the fetus.
• Playing a role in female pigmentation (skin whitening).
• Involvement in the development of certain brain nerves.
• Contributing to sexual satisfaction.
• Supporting pancreatic development.
• Lowering estrogen levels in women and testosterone levels in men.

Normal Prolactin Levels

• Men: less than 15 ng/ml
• Women: less than 20 ng/ml
• Pregnant women: between 10 and 300 ng/ml

Causes of Prolactin Deficiency in Men

Several factors can lead to low prolactin levels in men, including:

• Prolonged loss of appetite.
• Use of certain medications for Parkinson’s disease.
• Excessive intake of drugs that lower prolactin levels.
• Disorders affecting pituitary gland function.
• Pituitary tumors.
• Brain hemorrhage caused by trauma or other reasons.

Symptoms of Prolactin Deficiency in Men

Signs that may indicate low prolactin levels include:

• Low sperm count and poor sperm quality.
• Premature ejaculation.
• Sexual dysfunction and erectile weakness.
• Difficulty conceiving children.
• Anxiety and mood disturbances.
• Thyroid gland tumors.
• Depression.
• Persistent hunger.
• Excess dopamine production.
• Unexplained weight loss.

Diagnosis

Diagnosing prolactin deficiency involves:

• Clinical examination.
• Measuring blood prolactin levels.
• Testing testosterone levels.
• MRI scans to evaluate the pituitary gland.
• Imaging studies.

Treatment

Treatment focuses on addressing the root cause of prolactin deficiency and includes:

• Treating underlying medical conditions.
• Following a balanced diet rich in vitamins, minerals, proteins, healthy fats, and fiber.
• Avoiding excessive use of medications that affect prolactin levels.
• Engaging in regular physical exercise.
• Maintaining adequate hydration.
