Hyperprolactinemia, characterized by abnormally high levels of prolactin, may cause galactorrhea (production and spontaneous flow of breast milk), infertility, and menstrual disruptions in women. In men, it can lead to hypogonadism, infertility and erectile dysfunction. Prolactin is crucial for milk production during pregnancy and lactation.
The condition can occur in males as well as females. Relatively common etiologies include prolactinoma, medication effect, kidney failure, granulomatous diseases of the pituitary gland, and disorders which interfere with the hypothalamic inhibition of prolactin release. Ectopic (non-pituitary
A prolactinoma is a tumor of the pituitary gland that produces the hormone prolactin.It is the most common type of functioning pituitary tumor. [1] Symptoms of prolactinoma are due to abnormally high levels of prolactin in the blood (hyperprolactinemia), or due to pressure of the tumor on surrounding brain tissue and/or the optic nerves.
This mating can cause bi-daily surges of prolactin which would normally occur in rodent pregnancy. [39] Prolactin surges initiate the secretion of progesterone which maintains pregnancy and hence can initiate pseudopregnancy. The false maintenance of pregnancy exhibits the outward physical symptoms of pregnancy, in the absence of a foetus. [40]
Galactorrhea can also be caused by antipsychotics that cause hyperprolactinemia by blocking dopamine receptors responsible for control of prolactin release. Of these, risperidone is the most notorious for causing this complication. [5] Case reports suggest proton-pump inhibitors have been shown to cause galactorrhea.
Hyperprolactinaemia is the most common cause of AHH. It is a well-established cause of infertility in both male and female mammals. [13] Prolactin inhibits GnRH neurons and therefore inhibits the subsequent release of LH, FSH and sex steroids. The mechanism of prolactin induced inhibition of GnRH release is poorly understood. [13]
A review showed that ED is commonly seen in men with high blood pressure. It also noted that this dysfunction problem could be a side effect of antihypertensive medications.
High levels of prolactin in the blood (which may occur as a result of certain tumors or as a side effect of certain medications) has been associated with gynecomastia. [26] A high level of prolactin in the blood can inhibit the release of gonadotropin-releasing hormone and therefore cause secondary hypogonadism.
