Thyrotrophin and prolactin responses to thyrotrophin-releasing hormone in patients with streak gonad syndrome.
Plasma TSH and Prl responses to iv TRH (200 micrograms) were studied in 21 euthyroid patients with streak gonad syndrome which is characterised by high levels of FSH and LH and low level of oestrogen and in 9 healthy women. The syndrome is associated with a variety of chromosome complements. Basal TSH and Prl responses to TRH were normal in patients with streak gonads irrespective of their chromosomal complements. Peak levels of both the TSH and Prl occurred at 15-30 min following TRH. The data might suggest that in hypergonadotrophic oestrogen deficiency neither the TSH nor the Prl response to TRH are attenuated. It does not seem that the associated chromosome anomalies alter the TSH and Prl responses to TRH in euthyroid affected patients.
