Prolactin is a hormone produced by the pituitary gland in the brain. It plays a vital role in the production of breast milk after childbirth, but it also has other important functions in the body. Abnormal prolactin levels can indicate a medical condition, such as a prolactinoma, which is a tumor of the pituitary gland that leads to excessive prolactin production.
Having too much prolactin can cause a variety of symptoms and health issues. In women, it can disrupt the menstrual cycle, leading to irregular or absent periods. It can also cause infertility by suppressing ovulation. In men, high prolactin levels can cause erectile dysfunction and decrease libido.
Prolactin levels can go up naturally in certain situations. For example, during pregnancy, prolactin levels rise significantly to prepare the body for breastfeeding. They can also increase temporarily after nipple stimulation and sexual intercourse. Additionally, stress, sleep, and exercise can affect prolactin levels. Therefore, a single elevated reading does not necessarily indicate a problem.
If abnormal prolactin levels persist or cause symptoms, it is important to seek medical attention. A healthcare provider will perform a blood test to measure prolactin levels and determine the cause. Treatment options may include medication to lower prolactin levels or surgery to remove a prolactinoma. Regular monitoring of prolactin levels is crucial for maintaining hormonal balance and overall health.
What is it used for
Prolactin is a hormone that plays a crucial role in various aspects of health. It is primarily known for its role in breast milk production. When a woman is pregnant or breastfeeding, elevated levels of prolactin help stimulate milk production, enabling her to nourish her baby. Prolactin also has other important functions in the body, such as regulating the immune system and the body’s metabolism.
However, there are instances where prolactin levels may be too high or too low, leading to health issues. For example, in some cases, a condition called prolactinoma can occur, where a benign tumor in the pituitary gland causes excessive production of prolactin. This can result in symptoms such as irregular menstrual periods, infertility, and even milk production in women who are not pregnant or breastfeeding.
Major health insurance companies have faced legal trouble over their claim denial practices. In February 2018, the insurance commissioner of California announced plans to investigate Aetna’s coverage denial practices after a former medical director of the insurance company admitted that he never once looked at a patient’s medical records when deciding whether to deny claims over the three years he worked in the position, according to CNN.
To diagnose and manage these conditions, doctors may order a blood test to measure prolactin levels. This test is often performed in women who are experiencing menstrual irregularities, infertility, or symptoms suggestive of a prolactinoma. By measuring the amount of prolactin in the blood, doctors can determine if there is an issue with the hormone’s production and take appropriate measures to address it.
Treatment for high prolactin levels depends on the cause and may involve medication to lower prolactin production, surgery to remove a prolactinoma, or radiation therapy. By effectively managing prolactin levels, many of the associated symptoms can be alleviated, improving overall health and well-being.
In summary, prolactin is an essential hormone for various bodily functions, primarily known for its role in breast milk production. Abnormal levels of prolactin can lead to health issues, such as irregular menstrual periods, infertility, and prolactinoma. Through appropriate diagnosis and management, the effects of high prolactin levels can be mitigated, improving overall health and fertility.
Why do I need a prolactin levels test
A prolactin levels test is a medical examination that measures the amount of prolactin hormone in your body. Prolactin is a hormone produced by the pituitary gland, which is located at the base of your brain. Its primary function is to stimulate milk production in women after childbirth. However, prolactin also plays a role in regulating the menstrual cycle and fertility in both men and women.
Menstrual Irregularities and Infertility
Abnormal levels of prolactin in your body can cause menstrual irregularities and infertility. High levels of prolactin can disrupt the normal menstrual cycle and lead to irregular or missed periods. In some cases, it can even cause complete absence of menstruation. This hormonal imbalance can make it difficult for women to conceive and can be a sign of underlying fertility issues. On the other hand, low levels of prolactin can also affect fertility by interfering with the development and release of eggs in women.
Prolactinoma
Prolactinoma is a benign tumor of the pituitary gland that causes excessive production of prolactin. This condition can lead to elevated prolactin levels in the body. Symptoms of prolactinoma include irregular periods, infertility, decreased libido, and milk production outside of pregnancy and breastfeeding. A prolactin levels test can help diagnose prolactinoma and guide the appropriate treatment.
Overall, a prolactin levels test is crucial in understanding the hormonal balance in your body. It can help identify any abnormalities in prolactin production that may be causing menstrual irregularities, infertility, or other related symptoms. By detecting and addressing these issues, it can improve your chances of becoming pregnant and maintaining a healthy reproductive system.
Note: If you are planning to take a prolactin levels test or have any concerns about your hormonal health, it is important to consult with a healthcare professional for proper evaluation and guidance.
What happens during a prolactin levels test
During a prolactin levels test, a healthcare professional will take a sample of your blood to check the levels of the hormone prolactin in your body. Prolactin is responsible for the production of milk in breastfeeding women, and it also plays a role in regulating the menstrual cycle in women who are not pregnant. In men, prolactin helps to control the immune system, metabolism, and reproductive functions.
To perform the test, the healthcare professional will cleanse the area where the blood sample will be taken and use a needle to draw blood from a vein, usually in the arm. The collected blood will then be sent to a laboratory for analysis.
There are several reasons why a prolactin levels test may be recommended. If you are experiencing symptoms such as a milky discharge from the breasts, irregular or absent menstrual periods, or infertility, this test can help determine if high levels of prolactin are the cause. Additionally, the test may be done to monitor the effectiveness of treatment for a prolactinoma, a benign tumor on the pituitary gland that can cause elevated levels of prolactin.
Preparing for the test:
There are usually no specific preparations required for a prolactin levels test. However, your healthcare provider may ask you to avoid certain medications before the test, as some medications can affect prolactin levels. It is important to follow any instructions given to you by your healthcare provider.
What to expect during the test:
The prolactin levels test is a simple and relatively quick procedure. The healthcare professional will clean the area and insert a needle into your vein to collect the blood sample. You may feel a little pinch or prick as the needle is inserted, but the discomfort is usually minimal. After the sample is taken, a small bandage will be applied to the site to stop any bleeding.
Once the blood sample has been collected, you can resume your normal activities. There are usually no side effects or complications associated with a prolactin levels test.
Conclusion
A prolactin levels test is a common diagnostic tool used to measure the levels of the hormone prolactin in the body. By evaluating prolactin levels, healthcare professionals can assess reproductive health, identify potential issues such as hormonal imbalances or tumors, and guide appropriate treatment plans. If you have any concerns or questions about the test, it is best to consult with your healthcare provider.
Will I need to do anything to prepare for the test
Before the prolactin level test, there are a few things you can do to prepare your body and ensure accurate results.

There are no known risks associated with the prolactin test. It is a simple and non-invasive blood test that poses little to no risk to your health. The test is usually performed by taking a blood sample from a vein in your arm. The procedure is generally well-tolerated and does not cause any significant pain or discomfort.
However, like any medical test, there may be a small risk of bleeding, bruising, or infection at the site where the blood is drawn. This risk is minimal and can be further decreased by ensuring that the healthcare professional performing the test follows proper sterilization procedures.
In rare cases, a sudden drop in prolactin levels after the test may cause a temporary disruption in your menstrual cycle. This may result in a missed or delayed period. If you are pregnant or suspect that you might be pregnant, it is important to inform your healthcare provider before undergoing the test, as high levels of prolactin can sometimes be associated with certain complications of pregnancy.
In some cases, very high levels of prolactin may indicate the presence of a prolactinoma, which is a non-cancerous tumor of the pituitary gland. If you have been diagnosed with a prolactinoma or suspect that you might have one, it is important to discuss the potential risks and benefits of the test with your healthcare provider.
Overall, the prolactin test is a safe and reliable way to measure the levels of prolactin in your body. It is an important tool in diagnosing and managing various conditions related to prolactin production, such as infertility or irregular menstrual periods. If you have any concerns or questions about the test, it is always best to consult with your healthcare provider.
What do the results mean
When your prolactin levels are high, it indicates excessive production of prolactin hormone by your pituitary gland. This could be due to a variety of reasons, such as a prolactinoma, a noncancerous tumor of the pituitary gland. High prolactin levels can interfere with your menstrual cycle, causing irregular or absent periods. It can also lead to infertility by disrupting ovulation.
If your prolactin levels are low, it could mean that the production of prolactin is insufficient. This can negatively impact your health, especially if you are pregnant or breastfeeding, as prolactin plays a crucial role in milk production.
If your test results show normal prolactin levels, it means that your body is producing an appropriate amount of prolactin. However, it is important to note that prolactin levels can vary throughout the day, so additional tests may be required to confirm the results.
If your prolactin levels are outside the normal range, further investigation may be necessary to determine the underlying cause. Your healthcare provider may recommend additional tests to assess the health of your pituitary gland and rule out conditions that could be contributing to the abnormal prolactin levels.
