[GnRH-TRH and arg-GnRH-TRH test in females with normoprolactinemic galactorrhea].

In 8 patients aged from 17 to 48 years (average age 32,6 years) with normoprolactinemic galactorrhea a stimulation test with GnRH-TRH or arginine-GnRH-TRH was performed. The basal and stimulated serum levels of LH, FSH, PRL, TSH, HGH and total thyroxine (T4), the thyroxine binding capacity (TBC) and the free thyroxine index (FT4-I) were determined. -In a few cases there were disturbances of both the basal and the stimulated serum levels of the hormones. -Both the menstrual disorders which were seen in all patients with galactorrhea and the hormonal disturbances are discussed in context of an hypothetical increase of the PRL receptor sensibility in face of normal PRL serum levels or as a hint at a transient hyperprolactinemia.
