Oocyte cryopreservation couldalso meet the expectancies of ladies wishing to maintain their fertility forsocial purposes. within the previous few years, advances in cryopreservationmethodologies have dramatically enhanced the potency of oocytecryopreservation, resulting in the start of over one thousand infants andchallenging the supremacy of embryo cryopreservation because the preferredform of fertility upkeep. this article has been conceived with the purpose of delivering a complete view of the state-of-the-art of oocyte cryopreservation. It covers primary thoughts of low temperature garage (controlled expense gradual cooling andvitrification), points of oocyte body structure suitable to the method ofcryopreservation, crucial organic and scientific facts, and ethicalimplications of oocyte cryopreservation, thereby delivering a completeoverview of growth during this technique in assisted copy.
