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 کاملP-30: Developmental Capacity and Blastocyst Formation of Thawed Tetrahedral Versus Non-Tetrahedral 4-cell Stage Mouse Embryos After Vitrification
Background: It was reported in a literature that approximately one third of the 4-cell stage embryos did not exhibit a tetrahedral shape. Non-tetrahedral embryos showed a lower in vitro developmental potential than tetrahedral embryos. Recently vitrification technology has been widely employed for embryo cryopreservation. The objective of this study was to prove our hypothesis that vitrified - ...
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 کاملThe Effects of Plla Nanofiber Scaffold on Proliferation of Frozen-Thawed Neonate Mouse Spermatogonial Stem Cells
Purpose: To investigate of the effects of a poly L-lactic acid (PLLA) nanofiber scaffold on proliferation of frozen-thawed neonate mouse spermatogonial stem cells.Materials and Methods: Spermatogonial cells were isolated from neonatal 3-6-day-old NMRI mice testes by two steps enzymatic digestion and differential plating. The isolated spermatogonial cells were divided into four culture groups: 1...
