Exploring self-detection of the endogenous LH surge using a urine test as a tool to predict a suboptimal response to gonadotropin-releasing hormone agonist trigger during in vitro fertilization cycles.

Due to a high false negative rate, self-testing of endogenous LH release using a LH urine test when performed approximately 12-hours after triggering does not seem to be a reliable method to predict a suboptimal response to gonadotropin-releasing hormone.
