Fertility Preservation in Poor Ovarian Reserve Patients

Poor ovarian reserve (POR) patients have a limited reproductivelifespan to conceive with their own eggs so clinicians shoulduse controlled ovarian s timulation (COS) protocols whichmaximize the number of achieved oocytes. Majority of thesewomen need to undergo IVF and accept lower oocytes number,lower pregnancy rate and higher pregnancy loss compared toage-matched women with normal ovarian reserve. Because ofoocytes quality and quantity reduction, shortage of reproductivelifespan, decision to delay conception and other reasons;infertility risk increases and patients should be counselled aboutfertility preservation options. Embryo, oocyte and ovarian tissuecryopreservation can be performed as fertility preservations trategies. Firs t choice is embryo cryopreservation that is evenmore widely available and long-es tablished part of assis tedreproduction. But if it is not applicable at the time of puncture,oocyte cryopreservation can be performed. Ovarian tissuecryopreservation is the las t and important choice especiallywhen there is no time for ovarian s timulation but according toESHRE guideline it should probably not be offered to patientswith low ovarian reserve.
