Introduction
Prolactin is a hormone produced by the pituitary gland that plays a role in reproductive health. Elevated prolactin levels can cause hypogonadism, infertility, and sexual dysfunction in men. At Crossroads Urology, prolactin testing is an important diagnostic tool for evaluating hormonal imbalances and their impact on urologic health.
Purpose
Prolactin testing is used to:
- Diagnose hyperprolactinemia, a condition characterized by elevated prolactin levels.
- Evaluate causes of low testosterone (hypogonadism), erectile dysfunction, or infertility.
- Monitor patients with pituitary gland disorders, such as prolactinomas.
- Assess unexplained symptoms like decreased libido, fatigue, or gynecomastia.
Procedure
- A blood sample is drawn from a vein in the arm.
- The sample is analyzed in a laboratory to measure prolactin levels.
- Results are typically available within 1-2 days.
Preparation
- Avoid eating or drinking (other than water) for 8 hours before the test to improve accuracy.
- Testing is best performed in the morning, as prolactin levels can fluctuate throughout the day.
- Inform the provider of any medications, such as antipsychotics or antidepressants, that may affect prolactin levels.
Risks and Considerations
- Testing is safe, with minimal risks associated with blood draws, such as bruising or discomfort.
- Elevated prolactin should be interpreted alongside other hormonal markers, such as testosterone and LH, to identify the underlying cause.
At Crossroads Urology, we use prolactin testing to identify hormonal imbalances and develop targeted treatment plans.
Results
- Normal Prolactin Levels: Typically less than 20 ng/mL in men, though ranges may vary slightly by laboratory.
- Elevated prolactin may indicate a prolactinoma (pituitary tumor), hypothyroidism, or medication side effects.
- Low levels are rare and generally not clinically significant.
Conclusion
Prolactin testing is an essential tool for diagnosing hormonal imbalances that can affect reproductive and sexual health. At Crossroads Urology, we combine prolactin testing with expert care to create personalized solutions for our patients.
