چکیده

A 36 year old patient underwent in-vitro fertilization (IVF) and embryo transfer. Three embryos were transferred to her uterus and eight spare embryos were cryopreserved. The patient conceived a quadruplet pregnancy and delivered two boys and two identical twin girls by Caesarean section at 30 weeks gestation. The couple subsequently donated their cryopreserved embryos to the embryo donation programme for the use of other couples. Two agonadal patients received these cryopreserved-thawed embryos, each in a hormone replacement cycle. Both conceived, one has safely delivered twins and the other conceived a twin pregnancy, one of the fetuses has vanished and the other is progressing normally. The overall embryo implantation rate was seven out of nine (78%).

O-24: Increased Homocysteinein PCOS Affects Oocyte and Embryo Quality

Background: The biochemical characteristics of the follicular fluid (FF) play essential role in oocyte quality, the subsequent fertilization potential and embryo development. The oocyte quality and metabolism largely depends on follicular microenvironment. Present study aimed to investigate the relationship between oocyte quality and FF homocysteine (Hcy) level in women undergoing to IVF treatm...

Background: The cryopreservation of human oocyte would make significant contribution to fertility treatments. It could also provide on alternative to embryo preservation for avoidance ethical problems. Embryo cryopreservation is now a successful procedure, but oocyte cryopreservation has poorer results. Materials and Methods: For retrieval of oocyte NMRI mouse were used. after administration of...

Background Current strategies based on random selection of MII-oocytes to fertilize appear unsatisfactory in selecting the best number and the most vital oocytes to fertilize especially in poor responder women in which “chronological age” does not mismatch with “biological age”. The metabolomics- profiling approach, evaluating the final products of cell regulatory process (genome/transcriptome/...

P-30: The Investigation of Transcript Expression Level of Mitochondrial Transcription Factor A (TFAM) during In Vitro Maturation (IVM) in Single Human Oocytes

Background In vitro maturation (IVM) of human oocytes has acquired increasing attention in infertility treatment with great promise. This technique is an alternative conventional in vitro fertilization-embryo transfer (IVF-ET), and can be reduced the side effects of gonadotropin stimulation such as ovarian hyperstimulation (OHSS). Oocyte maturation is a complex process including cytoplasmic and...
