  2. Hyperprolactinaemia - Wikipedia

    en.wikipedia.org/wiki/Hyperprolactinaemia

    A blood serum prolactin level of 1000–5000 mIU/L (47–235 ng/mL) may arise from either mechanism, however levels >5000 mIU/L (>235 ng/mL) is likely due to the activity of an adenoma. Prolactin blood levels are typically correlated to the size of the tumors.

    en.wikipedia.org/wiki/Prolactin

    The serum concentration of prolactin can be given in mass concentration (μg/L or ng/mL), molar concentration (nmol/L or pmol/L), or international units (typically mIU/L). The current IU is calibrated against the third International Standard for Prolactin, IS 84/500.

  4. Prolactinoma - Wikipedia

    en.wikipedia.org/wiki/Prolactinoma

    The higher the prolactin level the lower the chance of normalizing serum prolactin. In the best medical centers, surgery corrects prolactin levels in 80% of patients with a serum prolactin less than 250 ng/ml. Even in patients with large tumors that cannot be completely removed, drug therapy may be able to return serum prolactin to the normal ...

  5. Galactorrhea hyperprolactinemia - Wikipedia

    en.wikipedia.org/wiki/Galactorrhea_Hyperprolac...

    Galactorrhea hyperprolactinemia is increased blood prolactin levels associated with galactorrhea (abnormal milk secretion). It may be caused by such things as certain medications, pituitary disorders and thyroid disorders. The condition can occur in males as well as females.

  6. Macroprolactin - Wikipedia

    en.wikipedia.org/wiki/Macroprolactin

    The most common complex found in blood consists of prolactin and immunoglobulin G (IgG). [1] While the free prolactin hormone is active, prolactin in the macroprolactin complex does not have any biological activity in the body and is considered benign. [2] However, macroprolactin is detected by all Laboratory tests that measure prolactin in ...

  7. Hypoprolactinemia - Wikipedia

    en.wikipedia.org/wiki/Hypoprolactinemia

    Hypoprolactinemia can result from autoimmune disease, [2] hypopituitarism, [1] growth hormone deficiency, [2] hypothyroidism, [2] excessive dopamine action in the tuberoinfundibular pathway and/or the anterior pituitary, and ingestion of drugs that activate the D 2 receptor, such as direct D 2 receptor agonists like bromocriptine and pergolide, and indirect D 2 receptor activators like ...

    There appears to be the greatest cluster of substances in the yellow part (μg/L or nmol/L), becoming sparser in the green part (mg/L or μmol/L). However, there is another cluster containing many metabolic substances like cholesterol and glucose at the limit with the blue part (g/L or mmol/L).

  9. Breast development - Wikipedia

    en.wikipedia.org/wiki/Breast_development

    With suckling from the infant, prolactin and oxytocin are secreted and mediate milk production and letdown, respectively. [20] [21] [29] Prolactin suppresses the secretion of LH and FSH, which in turn results in continued low levels of estrogen and progesterone, and temporary amenorrhea (absence of menstrual cycles) occurs.
