Premature ovulation

Releasing eggs before they can be collected.

Treatment

If the LH surge escapes suppression, follicles can release their eggs before the collection procedure, making retrieval unsuccessful. Antagonist and agonist protocols are designed to prevent this, and monitoring aims to detect the risk early so timing can be adjusted.

Also known as: early ovulation, escaped LH surge
