Abstract
A combined test with LHRH and TRH was investigated in the normal female subject during the menstrual cycle. LH and FSH responses were not affected by raised prolactin or TSH levels after TRH.No correlation was seen between either basal levels or responses of prolactin and TSH after TRH, and no difference in responses on days 4 or 24 were observed. The increments in prolactin and TSH were significantly greater in female than in male subjects.Although FSH responses to LHRH+TRH were not significantly different, LH responses on day 24 were greater than on day 4. A significant linear correlation between FSH and LH responses to LHRH was seen.The results indicate that prolactin and TSH responses to TRH are greater in female than male subjects and that changes in LH and FSH after LHRH do affect these responses. Normal ranges for hormone responses after LHRH and TRH are defined.
