Peripheral estrogen receptor-alpha selectively modulated the waveform (shape) of GH secretory bursts in healthy women without changing overall GH levels — revealing a subtle but functionally important estrogen effect on GH release quality.
Key findingPeripheral ER-alpha activation selectively altered GH secretory burst waveform (mass, amplitude, duration) without changing overall GH output in women
What the researchers found
Peripheral ER-alpha activation selectively altered GH secretory burst waveform (mass, amplitude, duration) without changing overall GH output in women — demonstrating estrogen modulates the QUALITY of GH release, not just quantity, with functional implications for GH bioactivity.
