The Analysis of Factors Affecting the Success Rate of Frozen Thawed Embryos in IVF / ICSI Cycles
Purpose: the aim of this study is to analyze the factors contributing to the success of frozen- thawed embryo transfer (ET). Material and method: This retrospective, case-control study was carried out on 700 infertile couples treated with IVF and ICSI and had embryo freezing in Isfahan Fertility and Infertility Center, Iran, from the beginning of July 2000 to the end of June 2003. Results: fa...
متن کاملHuman pregnancy after transfer of intact frozen-thawed embryos.
Since the birth of the first baby as a result of in vitro fertilisation (IVF) in 1978, many clinics around the world have achieved pregnancies and births for their patients by using IVF and gamete intrafallopian transfer procedures. With the storage of excess embryos, multiple laparoscopies can be avoided; this has favoured the development of better cryopreservation techniques. In our clinic 8-...
متن کاملMouse embryos generated from frozen-thawed oocytes can successfully survive a second cryopreservation.
BACKGROUND To determine whether mouse embryos generated from frozen-thawed oocytes can successfully survive a second cryopreservation. METHODS Immature C57BL6*BALB/c female mice underwent superovulation and the collected oocytes were divided into three groups. Group A oocytes (n = 107) underwent IVF. Group B oocytes (n = 167) underwent IVF and embryos generated were then cryopreserved. Group ...
متن کاملO-23: Transfer of Blastocysts Derived from Frozen Thawed Cleavage Stage Embryos Improved Ongoing Pregnancy
Background: The aim of our study was to compare the resulting from transfer of embryos that cryopereserved in cleavage stage after thawing and transfer of embryos after thawing and culture in sequentional media until blastocyst formation. Materials and Methods: In this prospective clinical study, we have evaluated 128 cycles in women undergone in vitro fertilization (IVF) or intracytoplasmic sp...
متن کاملRecovery, survival and functional evaluation by transplantation of frozen-thawed mouse germ cells.
BACKGROUND Establishing a successful method for testicular stem cell transplantation of frozen-thawed testicular cells would be of immense benefit to boys with childhood cancer undergoing a sterilizing treatment. In this study, we evaluated different cryopreservation protocols in a mouse model by means of testicular germ cell transplantation (TGCT), in order to establish an optimal freezing pro...
