چکیده
Human oocytes were collected by laparoscopy and fertilized and cultured in vitro. Human chorionic gonadotropin was detected in the medium surrounding two embryos cultured for more than 7 days after fertilization.

The Evaluation of Melatonin Effect on In-Vitro Development of Mouse Preimplantation Embryos
Purpose: Melatonin promotes in-vitro embryo development in different species. This study studied the effects of melatonin on in-vitro mouse preimplantation embryo development. Materials and Methods: Two-cell embryos were obtained from oviduct of 6-8 weeks female NMRI mice 48 hours after administration of an intra-peritoneal injection of 5 IU/ml pregnant mares’ serum gonadotrophin and subsequent...
متن کاملThe Effect of Human Follicular Fluid (FF) on Preimplantation Mouse Embryo Development in Vitro
SUMMARY Since at oocyte retrieval for in vitro fertilization there is some FF become incorporate to egg, we decided to investigate the effect of this fluid on preimplantation embryo development in vitro. FF was obtained at the time of oocyte retrieval for IVF, centrifuged and then either inactivated by heat and stored at 4°c or without inactivation stored at-20°c until used. Late 2-cell emb...
متن کاملImprovement in Development and Quality of 8 Cell Mouse Embryos in Presence of Granulocyte Macrophage-Colony Stimulating Factor
Purpose: Granulose Macrophage-Colony Stimulating Factor (GM-CSF) is a lympho- heamatopoietic actor, secreted in the reproductive system. Murine pre- implantation embryos express GM-CSF receptors. In his study, the capacity of eight cell mouse embryos was studied in the presence and absence of GM-CSF. Materials and Methods: Female NMRI mice were super ovulated using Pregnant Mare Serum gonadotr...
متن کاملSuccessful production of offspring after superovulation and in vitro culture of embryos from domestic ferrets (Mustela putorius furos).
In an effort to expand the use of ferrets as models for genetic disease, several experimental parameters that are required for successful genetic manipulation in this species were investigated. Optimum superovulation (19.3 +/- 0.6 oocytes and embryos per female) was achieved after injections of 100 iu equine chorionic gonadotrophin (eCG) and 150 iu human chorionic gonadotrophin (hCG). The ovula...
