Yes, high prolactin (hyperprolactinemia) is a form of hormone imbalance, often caused by a pituitary tumor, medications, or other health conditions, leading to issues like irregular periods, infertility, low sex drive, erectile dysfunction, and milky breast discharge in both men and women by disrupting estrogen and testosterone production.
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 may have elevated prolactin levels without any symptoms.
Left untreated, high prolactin levels can also lead to osteopenia and/or osteoporosis. If the prolactinoma is large (macroprolactinoma), it may also cause the following symptoms: Headaches. Nausea and/or vomiting.
The pituitary gland can make a high amount of prolactin due to reasons other than a prolactinoma, including: Medicines. Other types of pituitary tumors. Kidney disease.
Symptoms
Higher-than-normal prolactin levels can have different causes: Prolactinoma, a benign (noncancerous) tumor growing on the pituitary gland. This is the most common cause. This type of tumor makes prolactin, which leads to higher-than-normal levels of prolactin in the blood.
Symptoms in women include irregular periods, milky breast discharge, and low estrogen. Men may experience low libido, erectile issues, or breast enlargement. Diagnosis involves a blood test for prolactin levels and medical imaging to check for a pituitary tumor.
Unsurprisingly, vitamin D levels might impact hypophyseal production or activity of hormones such as growth hormone, gonadotropins (follicle-stimulating hormone, luteinizing hormone), prolactin, corticotropin, and thyroid-stimulating hormone (TSH).
Prescription Medications: Medicines called dopamine agonists like bromocriptine and cabergoline can decrease prolactin production and usually decrease the size of prolactinomas even when the tumor is large. Medicines work well for most people with prolactinomas and are well tolerated.
The most potent stimulator for prolactin synthesis is suckling or nipple stimulation. This mechanical process stimulates sensory nerves in the nipple that carry the signal via the spinal cord to the arcuate nucleus, which inhibits dopamine release, thus removing the inhibitory action of dopamine on prolactin.
Hyperprolactinemia results in impaired body composition with greater waist circumference, body weight and BMI, and increased body fat percentages only in men. An improvement in body weight and BMI is possible by normalizing PRL levels, although after long-term therapy.
Post-partum women who had high prolactin levels were significantly more hostile than a control group of employees and as hostile as hyperprolactinemic women. Hyperprolactinemic males were no more hostile than controls. The relationship of prolactin to post-partum aggression in mammals is briefly reviewed.
Doctors may order the test to help diagnose or monitor treatment of prolactinoma. They also may order one as part of testing for conditions linked to changes in prolactin levels, such as irregular menstrual periods, fertility problems, some thyroid or adrenal gland problems, anorexia, and polycystic ovarian syndrome.
If no tumor is detected and there is no other apparent cause of the high prolactin level (such as a medication), a pituitary tumor is still the most likely cause, particularly in women. In this case, the tumor is probably too small to be seen on the scan.
Prolactin demonstrated a characteristic circadian release pattern with elevation during dark and diminution during light. High prolactin levels were linked to non-rapid eye movement sleep and electroencephalogram delta activity in humans.
After a 16-week treatment period, the vB6 group showed a 68.1% reduction in serum prolactin levels (from 95.52 ± 6.30 μg/L to 30.43 ± 18.65 μg/L) while the ARI group showed only a 37.4% reduction (from 89.07 ± 3.59 μg/L to 55.78 ± 7.39 μg/L). During weeks 1–4, both treatments reduced prolactin similarly.

For reference: Hyperprolactinemia is a condition in which prolactin levels are elevated in the blood. Prolactin is secreted in the pituitary gland, a gland located in the very center of the brain, which is the most important or "controlling" endocrine gland of the body.
Furthermore, increased levels of thyroid-stimulating hormone (TSH) seen in hypothyroidism are often associated with increased prolactin levels, which leads to a delay in luteinizing hormone (LH) response and abnormal ovulation.

Increased prolactin is also seen in lactation, pregnancy, and the post-partum state. Multiple medications can also increase prolactin levels. These include estrogens, dopamine blockers/antagonists, some stomach acid reducers, opiates, some high blood pressure medications, anti-depressants, and anti-psychotics.
[35] found that Vit. D administered to patients with prolactinoma increases the 25(OH)D and reduces the serum PRL [34].
For anyone, hyperprolactinemia can cause the following symptoms:
Several studies have indicated that patients with hyperprolactinemia are more likely to experience depression, anxiety, and hostility (5, 6). These symptoms are generally alleviated after hyperprolactinemia is corrected, suggesting that prolactin plays a direct role in psychological disorders.
