Prolactin

This blood-based evaluation measures the amount of a hormone secreted by the pituitary gland. It plays a critical role in reproductive health, influencing breast development, menstrual cycle regulation, ovulation, and milk production after childbirth. In men, it also contributes to reproductive function and overall hormonal balance. Because hormone irregularities can present with vague or overlapping symptoms, this simple assessment provides clarity when investigating issues linked to fertility, menstruation, or hormonal health.

Levels of this hormone naturally fluctuate throughout the day, which is why morning testing is most accurate. Stress, lack of sleep, and certain medications—including antidepressants and blood pressure drugs can alter results.

Interpretation should always be guided by a healthcare provider, since minor deviations are not always concerning. Abnormal results may lead to further investigations, such as thyroid evaluations or imaging of the pituitary gland.

For individuals undergoing fertility treatment, monitoring this hormone helps personalize therapy plans and improve the likelihood of success.
