Seven female patients with amenorrhea, galactorrhea, and hyperprolactinemia were examined before and after selective transsphenoidal removal of a PRL-secreting microadenoma. Before adenomectomy, metoclopramide (MCP; 10 mg orally) and TRH (200 micrograms iv) did not increase PRL blood levels in any of the seven patients. On the contrary, after oral administration of 10 mg MCP, a positive response was noted in a group of eight lactating women 3 days postpartum. After surgery, serum PRL level returned to normal in all patients. A positive PRL response to MCP and TRH was found in six of the seven patients 1 month after surgery. One patient, who had the lowest PRL level, failed to show a PRL increase after both stimuli. These findings indicate that hypothalamic pituitary function can be restored to normal after transsphenoidal removal of PRL-secreting pituitary tumors.

Of 210 women with galactorrhea 66.2% had normal prolactin serum levels. Only in 33.4% elevated prolactin levels could be found, 0.4% were hypoprolactinemic. The TRH-stimulation test detected latent hyperprolactinemia in 13.5% of the cases, showed a normal thyroid function in 81.5%, hypothyroidism in 13.9% and hyperthyroidism in 4.6% and this is considered to be a more valuable diagnostic tool than the MCP-test. Galactorrhea was associated with the following conditions: hyperprolactinemia (34.8%), menstrual disturbances (67.4%), post-pill amenorrhea (30.2%), mastalgia (30.2%), prolactinoma (18.6%), fibrocystic disease (11.6%), hirsutism (4.6%), diabetes mellitus (2.3%).
