No eggs at retrieval despite many follicles — what happened?
Scan showed 14 follicles but retrieval got only immature eggs / almost none. The clinic mentioned timing of trigger. Can this be fixed next time?
Short answer: Unexpected low egg yield can relate to trigger timing/absorption, empty follicle syndrome (rare), technical factors or biological issues. Reviewing trigger type, timing, blood LH/hCG when used, and protocol changes often improves the next cycle.
Answer #1
Trigger and timing review
Eggs mature after the trigger shot; retrieval is usually about 34 to 36 hours later depending on protocol. Wrong timing, failed absorption of subcutaneous trigger, or pharmacy mix-ups are uncommon but important to exclude. Some clinics check post-trigger hormone levels when yield is unexpectedly zero.

Answer #2
Planning the next stimulation
Your team may change trigger type (hCG vs agonist vs dual), adjust timing, review needle technique, or reconsider whether follicles were truly mature size. Genuine empty follicle syndrome is rare. A detailed embryology and theatre note review should happen before another identical cycle.

Call your clinic or go to the hospital the same day if you have
- Severe pain or OHSS symptoms after retrieval attempt
