Self-Detection of the LH Surge in Urine After GnRH Agonist Trigger in IVF-How to Minimize Failure to Retrieve Oocytes.

Urine LH testing may be useful to confirm an LH surge after the GnRH agonist (GnRHa) trigger prior to oocyte retrieval in IVF. A prospective cohort study, including oocyte donors undergoing ovarian stimulation, treated with a GnRHa trigger for final oocyte maturation. Urine LH testing was performed at home, 12 h after the GnRHa trigger.
