Conclusions
1. Age and number of oocytes are the most powerful factors that affect success.
2. Differential survival and CLBR are observed in different indications:
o Young social freezers achieve similar outcomes as donors.
o Results are lower in young poor responders and onco FP patients.
o Cancer patients achieve lower survival and CLBR but this effect remains to be clarified.
3. Type of stimulation has no clear impact on final outcomes.
4. Older women need more oocytes to equate the outcomes of younger patients. Although the gain per oocyte is lower for older women.
5. 36 years could be considered as a limit between better and worse results: with 8 oocytes the CLBR rate is ~ 30% in patients ≤35; while in patients ≥ 36% the probability is ~ 15%
Closing Remarks
Women who consider elective oocyte cryopreservation should be encouraged to do so before the age of 35, although this could be less cost‐effective.
It remains important to counsel women that elective oocyte cryopreservation can increase future reproductive chances but cannot guarantee reproductive success.
We freeze GAMETES not fertility.
