Prolactin Test in Kochi

Prolactin is a hormone secreted by the pituitary gland that primarily stimulates breast milk production after childbirth. It also influences menstrual cycles, fertility, and sexual function in both women and men. Abnormal prolactin levels can disrupt ovulation, sperm production, and hormonal balance.

Prolactin testing helps diagnose pituitary disorders, infertility, and menstrual irregularities.

Why Is This Test Recommended?

This test is recommended to:

• Evaluate infertility
• Investigate menstrual irregularities
• Assess abnormal breast discharge
• Diagnose pituitary tumors (prolactinomas)
• Evaluate low libido or erectile dysfunction

Understanding Prolactin

Symptoms Requiring Prolactin Testing

• Irregular or absent periods
• Galactorrhea (milk discharge)
• Infertility
• Headaches or vision problems

Preparation

• Blood sample drawn in morning
• Avoid stress and nipple stimulation
• Fasting may be advised

FAQs

Can stress increase prolactin?

Yes, stress can temporarily elevate prolactin levels because it activates the body's fight-or-flight response, which influences the pituitary gland. To minimize this, try relaxation techniques before the test, and discuss any ongoing stressors with your doctor for accurate interpretation.

Is fasting required?

Often recommended, but not always mandatory—your healthcare provider may advise fasting for 8–12 hours to ensure stable hormone levels. If fasting isn't specified, a light meal is usually fine, but confirm with your lab or doctor to avoid any interference.

Can men have high prolactin?

Yes, men can experience high prolactin levels, which may cause symptoms like erectile dysfunction, reduced libido, or infertility. It's less common than in women but can stem from similar causes like pituitary issues or medications; testing is straightforward for both genders.

Is high prolactin treatable?

Yes, high prolactin (hyperprolactinemia) is highly treatable in most cases. Treatments include medications like dopamine agonists to lower levels, addressing underlying causes such as tumors, or lifestyle changes. Many patients see symptom relief and restored fertility quickly after starting therapy.

Is repeat testing needed?

Common, yes—repeat testing is often necessary to confirm results, monitor treatment effectiveness, or check for fluctuations due to factors like time of day or stress. Your doctor may schedule follow-ups every few weeks or months based on your initial findings and response to intervention.
