Oolemma invagination of fresh and cryopreserved human oocytes during in vitro fertilization by ICSI

Abstract: Oolemma invagination of fresh and cryopreserved human oocytes during in vitro fertilization by ICSI Реферат: Разработка новых прогностических критериев оценки оплодотворения in vitro нативных и криоконсервированных ооцитов является важной составляющей современных вспомогательных репродуктивних технологий. Проведено сравнение степени инвагинации оолеммы при интрацитоплазматическом введении спермия в нативные и криоконсервированные ооциты. Разработана классификация состояния тургора гамет в зависимости от степен… Show more

“…Therefore, cryopreservation of oocytes of patients at younger reproductive age, and storage of gametes in a cryobank for further transfer to the uterine cavity of these patients at older age is of great practical and psychological importance for achieving the desired pregnancy. 1,2 In addition to social indicators, women of reproductive age can resort to cryopreservation of oocytes in connection with gonadotoxic treatment, when conducting a donation program of oocytes in severe cases of infertility, when donating cytoplasm of oocytes in case of mitochondrial dysfunction or hereditary genetic abnormalities within the context of specialist reproductive technologies. [3][4][5] In many of these cases, the age of patients may be older, in contrast to those who resort to oocyte cryopreservation for social reasons.…”

“…The absence of ice crystals formation when the temperature was lowered to -196 С and at the stage of warming made it possible to reduce the level of cell damage and significantly increase the efficiency of oocyte cryopreservation comparing with slow freezing (Levi-Setti et al, 2016). Also using different technique prior to cryopreservation of oocytes and embryos at various preimplantation stages could help to preserve their functional characteristics in the women of younger ages (Petrushko et al, 2018;Petrushko et al, 2019). It should be noted that the state of the endometrium is also very important, when transferring embryos which contributes to the level of implantation.…”
