        @parthib Pregnancy.
        Puerperium.
        Breast stimulation.
        Stress - physical (including excessive exercise) or psychological - including venepuncture.
        Macroprolactinaemia:
        This refers to prolactin of high molecular mass, mostly complexes of monomeric prolactin with immunoglobulins (prolactin autoantibody complexes). These larger molecules have low bioactivity and a prolonged clearance rate similar to that of immunoglobulins. Depending on the immunoassay used, macroprolactinaemia may account for 25% of laboratory documented hyperprolactinaemia. Consider this cause in an asymptomatic patient with hyperprolactinaemia and consult laboratory staff.
        Pituitary tumours:
        Abnormally high levels of prolactin may be caused by a prolactin-secreting pituitary tumour or by a non-secreting pituitary tumour that prevents dopamine (prolactin release-inhibiting hormone) from reaching normal prolactin-producing cells.
        Prolactinomas:
        Microprolactinomas (the most common, approximately 90%).
        Macroprolactinomas (>10 mm size - approximately 10%).
        Pituitary or hypothalamic tumour compressing the pituitary stalk - eg, craniopharyngioma.
