The Claim
In euthyroid patients undergoing thyroid hormone replacement, the thyrotropin-stimulating hormone (TSH) response to synthetic thyrotropin-releasing hormone (TRH) is blunted, while the prolactin response to TRH remains unchanged.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In people taking thyroid hormone medication who have normal thyroid function, the pituitary gland releases less TSH in response to TRH, but releases the same amount of prolactin as before, indicating that the two hormones are regulated differently during hormone replacement.
See the scientific wording
In euthyroid patients undergoing thyroid hormone replacement, the TSH response to synthetic thyrotropin-releasing hormone (TRH) was blunted, while the prolactin response remained unchanged, suggesting differential regulation of these hormones during hormone replacement.
What the research says
1 studyWhen people take thyroid hormone medicine, their body stops responding as strongly to the signal that tells the thyroid to make more hormone — but it still responds normally to the signal that makes prolactin. This means the body treats these two signals differently.
