High prolactin effects on the body

When the prolactin level in the blood increases and the production of this hormone is in excess, this condition is called hyperprolactinemia. This hormone is responsible for milk production in women. However, elevated prolactin levels can cause problems in men and women. Prolactin is a peptide hormone. It is responsible for breast enlargement in women during pregnancy and milk production. This hormone is a protein made from amino acid chains. If the prolactin level increases, then it gives rise to the condition called hyperprolactinemia.

High levels of prolactin are produced by the tumor. Usually, these tumors are benign and can be large or small. They are also noncancerous. If the tumors are large, then they may cause vision problems, headache, and in some cases, both of the symptoms. This condition is more common in women than in men and rarely occurs in children. Prolactin levels may also increase due to certain prescription medicines. The following medications may cause the prolactin level to increase:.

Drugs can cause an elevated prolactin level, especially those drugs that can inhibit the function of dopamine, cause a low production of dopamine, or deplete the stores of dopamine in the brain.

These drugs include antipsychotics, drugs used to treat hypertensionand tranquilizers. They might cause the prolactin level to slightly rise. Many other diseases can also cause a rise in prolactin levels. The symptoms of menopause may also cause high prolactin levels. Sometimes, the cause of high prolactin levels cannot be determined. When an individual has an elevated prolactin level in the blood, doctors may order for an MRI scan of the brain to rule out pituitary tumors.JavaScript seems to be disabled in your browser.

How Do High Prolactin Levels Affect Fertility?

Prolactin levels also fluctuate throughout the dayand are higher during sleep, just after awakening and during times of emotional or physical stress. Prolactin is also released after orgasm.

This may explain part of the connection between prolactin and libido : Prolactin may be released even outside of sexual situations, impeding the body's ability to become aroused later. Prolactin has been studied to some extent in animals, as well. Researchers found that monkey's prolactin levels rise after being trapped in a cage. In general, more research is needed in relation to this hormone in order to fully understand all of its functions in both animals and humans.

Higher-than-average prolactin, also called hyperprolactinemia, often decreases sex drive. This may be because prolactin can decrease levels of sex hormones like testosterone in men and estrogen in women. These sex hormones play a big role in maintaining a healthy libido.

The causes of high prolactin levels aren't entirely understood, but researchers have been able to point to certain drugs, pituitary tumors, hypothyroid disease and vitamin B6 deficiency as possible causes.

Getting plenty of zinc is also thought to lower prolactin levels. Some examples of zinc-rich foods are shellfish, beef, beans and turkey. Low prolactin levels can also cause a decrease in libido. One study published in the Journal of Sexual Medicine showed evidence of a connection. Researchers measured participants' hormone levels, BMIs, cholesterol and blood sugar.

The men also answered questions about their health, lifestyle and libido. The researchers say that the study does not prove a direct cause-and-effect relationship between prolactin and libido, but rather an association that needs more research to be fully understood.

Low prolactin may directly cause low libido, low prolactin levels may be a symptom of something else causing low libido, or low prolactin levels and lower sex drive may both be caused by overall poor health. Because prolactin is thought to be released after orgasm, one simple solution to low prolactin levels is to have orgasms more frequently.

However, this only holds true for partnered sex; orgasm from masturbation has been found to release little to no prolactin.

Symptoms of High Prolactin Hormone Levels

If you suspect you may have abnormally-high or abnormally-low prolactin, your doctor can do a blood test. If your prolactin levels are abnormal, he or she may wish to check your pituitary gland and thyroid function.

Doctor Supported: A Message from Dr. Gerd Jansen, MD. High Prolactin and Libido Higher-than-average prolactin, also called hyperprolactinemia, often decreases sex drive. Effects of Low Prolactin Low prolactin levels can also cause a decrease in libido.Prolactin is a hormone produced by your pituitary gland which sits at the bottom of the brain. Prolactin causes breasts to grow and develop and causes milk to be made after a baby is born.

Normally, both men and women have small amounts of prolactin in their blood. Prolactin levels are controlled by other hormones called prolactin inhibiting factors PIFssuch as dopamine. During pregnancy, prolactin levels go up. After the baby is born, there is a sudden drop in estrogen and progesterone.

Hyperprolactinemia is a condition of too much prolactin in the blood of women who are not pregnant and in men. Hyperprolactinemia is relatively common in women. About a third of women in their childbearing years with irregular periods but normal ovaries have hyperprolactinemia.

When this happens, a woman might have trouble getting pregnant or her breasts may start producing milk outside of pregnancy galactorrhea.

Ninety percent of women with galactorrhea also have hyperprolactinemia. High prolactin levels interfere with the normal production of other hormones, such as estrogen and progesterone. This can change or stop ovulation the release of an egg from the ovary.

It can also lead to irregular or missed periods. Some women have high prolactin levels without any symptoms. In men, high prolactin levels can cause galactorrhea, impotence inability to have an erection during sexreduced desire for sex, and infertility.

A man with untreated hyperprolactinemia may make less sperm or no sperm at all.

Blood tests can measure levels of prolactin. Levels are sometimes higher if you have eaten recently or are under stress. Your doctor may also perform a physical exam to find any obvious causes or any breast discharge.

If levels are still high after the second check, your doctor may order a magnetic resonance imaging MRI scan of the brain to check for a tumor of the pituitary gland.

The treatment depends on the cause. If no cause is found or you have a tumor of the pituitary gland, the usual treatment is medicine. Hypothyroidism is treated with thyroid replacement medicine, which should also make prolactin levels return to normal.

If your regular medicine is the reason for your high prolactin levels, your doctor will work with you to find a different medicine or add one to help your prolactin levels go down. The most commonly used medicines are cabergoline and bromocriptine. Your doctor will start you on a low dose of one of these medications and slowly increase the dose until your prolactin levels go back to normal.

Treatment continues until your symptoms lessen or you get pregnant if that is your goal. Usually, your doctor will stop treatment once you are pregnant. Cabergoline is taken twice a week and has fewer side effects than bromocriptine. Generally, cabergoline drops prolactin levels to normal faster than bromocriptine does. Cabergoline can cause heart valve problems when taken in high doses, but these doses are not used in women who are trying to get pregnant.

Bromocriptine and cabergoline can been used when woman is pregnant. The most common side effects are lightheadedness, nausea, and headache. Slowly increasing the dose helps with side effects. Another way to decrease the side effects is to give bromocriptine in a suppository directly in the vagina. This is an off-label use of the medicine. Not all women with hyperprolactinemia need treatment, although women with hyperprolactinemia who do not make estrogen as a result need a treatment that either causes her to make estrogen or provides estrogen to the patient.Raised prolactin levels in a woman who is not pregnant or breast feeding reduces lipid fat metabolism.

Over 30 Swedish men and women may have raised levels of prolactin. Women who are pregnant or breast feeding have naturally raised levels of prolactin, but stress, some medicines and benign brain tumours can also lead to raised levels of the hormone. In women, an abnormally high level can cause menstrual disturbances and infertility, and may also result in insulin resistance. In her thesis Louise Nilsson shows that there are receptors for the breast feeding hormone in human fatty tissue.

This in turn increases the risk of cardiovascular disease. Materials provided by University of Gothenburg. Note: Content may be edited for style and length. Science News.

Otherwise, excess of prolactin may lead to medical problems. Prolactin is a hormone that is secreted by the anterior pituitary and released in episodes. This hormone appears in serum under 3 distinct forms. The target organ when it comes to prolactin is represented by the mammary gland where it exerts its galactopoietics and lacotgenic function. During pregnancy, the levels of this hormone increase under the influence the progesterone production and of increased levels of estrogen.

The most severe complications are found due to high amounts of prolactin. As a general rule, high prolactin amounts are detected through blood tests during medlcal examinations performed by a woman attempting to conceive and failing. Increased prolactin blocks ovulation and leads to infertility.

They may have side effects on fertility, leading to uncontrolled production of progesterone during the luteal phase. Hyperprolactinemia, in both men and women, represents the most cause involving fertility disorders.

For the detection of latent hyperprolactinemia, there are used stimulation tests with metoclopramide and thyroid relising hormone. Increased concentrations of prolactin inhibit ovarian steroidogenesis and also the production and secretion of pituitary gonadotropes. Abnormal prolactin levels can be determined by irregular ovulation and menstruation, which might make conception more difficult.

Actually hyperprolactinemia is seen as the most important infertility cause. Moreover, increased prolactin levels might affect the levels of progesterone, which is an indispensable hormone to the maintenance of pregnancy. Possible affections of the mammary gland may be possible, prolactin being the hormone that controls the lactate secretion after birth.

Signs include abnormal weight variations, swelling, headaches or breast enlargement. Compelling, to males who are singles, fathers usually have higher concentration of this hormone. Naturally, the prolactin level during the third trimester of pregnancy, during the first 18 months after the baby is born, when it has the role of blocking the egg production being seen as a natural contraceptive as well as stimulates the secretion of milk. Among the causes which may lead to prolactin imbalances are hormonal contraceptives taken without talking to a doctor first and especially without medical examinations that are required to find the ideal pill type which is compatible with the individual hormonal particularities of every woman.

The treatment for increased levels of prolactin is based on the causes of hormonal deficiency, and which may range from pituitary tumors to thyroid dysfunctions. Often, drugs solve this issue.

The test for detecting the level of prolactin in the blood can be asked by the doctor if the patient shows signs of prolactinoma a tumor that is found in the pituitary gland resulted because of excessive prolactin in the blood : galactorrhea breast milk secretion in other moments than when the baby is breastfedunexplained headache or vision disorders. The analysis might be advisable for women who may have irregular menstruation or infertility.

Furthermore, if they experience amenorrhea, they need to have their prolactin level monitored. The level of testosterone also needs to be tested. When the doctor may suspect someone of experiencing hypothyroidism a hormone deficiency of the pituitary glandhe might advise the person to do the prolactin test and the analysis of other levels of hormones, like growth hormones. During pregnancy, there are progressive growths recorded in the level of prolactin, reaching in the last trimester even concentrations 15 to 20 times higher than the initial level.

In men, the level of prolactin in the blood which is generally lower than in women remains rather constant from childhood to adulthood and elderhood.

When it comes to women, the prolactin level in the blood increases from puberty along with the decrease of the estrogen level and decrease when menopause occurs. From here, we notice that the most important factor that stimulates the prolactin production is the estrogen hormone more specifically endogenous, but exogenous as well, which is brought into the organism by medications, particularly contraceptives.Objective: Hyperprolactinaemia in humans may be associated with a high prevalence of obesity but the nature of this link is poorly defined.

The aim of this study was to establish the relationship between hyperprolactinaemia and body weight in patients with prolactin-secreting pituitary tumours.

Design: We conducted a retrospective study of prolactinoma patients treated at the Endocrine Institute of the Tel Aviv Medical Center, Israel, during the period Patients with clinically non-functioning pituitary macroadenomas NFA served as the control group. Data on demographic parameters, body weight before and during treatment, clinical presentation including history of weight fluctuations, tumour size as measured by computed tomography or magnetic resonance imaging, modalities and response to treatment, and pituitary function before and during treatment were recorded from medical files.

Patients: Forty-two patients with prolactinomas PR and 36 patients with clinically non-functioning macroadenomas NFA comprised the study population. Seventeen PR patients lost weight mean change Weight loss in patients with PR could not be attributed to altered pituitary function nor to compression of the third ventricle. Conclusion: Weight gain and elevated body weight are frequently associated with prolactinomas regardless of a mass effect on the hypothalamus or pituitary function.

We propose the inclusion of hyperprolactinaemia in the differential diagnosis of endocrine obesity and weight gain. Abstract Objective: Hyperprolactinaemia in humans may be associated with a high prevalence of obesity but the nature of this link is poorly defined. Substances Hormone Antagonists Bromocriptine Prolactin.Prolactin is a hormone secreted by the pituitary gland, a small structure in the brain which secretes other hormones. Prolactin's primary function is to enhance breast development and initiate lactation breastfeeding.

If you are having irregular menstrual periods, infertility, or breast milk leakage especially if you aren't nursing a babyyour physician may order a blood test to see if your prolactin levels are elevated. The condition occurs more commonly in women, although prevalence rates can vary among different populations. Estimates suggest that in a random adult sample, around 0.

Because a number of factors can affect the blood values, women should avoid breast stimulation and intercourse the night before the test.

Prolactin is believed to play a role in regulating sexual satisfaction and satiation. If the blood test comes back elevated, the doctor may wish to repeat the test, this time after fasting for at least 8 hours. Blood tests to assess the production of other pituitary hormones may be done and can be helpful to rule out other conditions causing similar symptoms.

The treatment for high prolactin levels is to return levels to normal ranges. Going forward, once prolactin levels are in normal ranges, your doctor may recommend you undergo regular monitoring of prolactin levels by doing blood tests. Occasionally, an MRI may also be needed to check the size of the tumor and look for growth.
