THE EFFECT OF DIFFERENT CULTURE MEDIA ON IN VITRO FERTILIZATION OF MICE

Abstract

The effect of different types of media on in vitro fertilization (IVF) of mice oocyte wasinvestigated. IVF was carried out in RPMI-1640 medium at recommended temperature (37 C) andpH (7.4). The obtained results showed that 63.73% of used oocytes were fertilized, and thepercentage of abnormal embryos was 27.58%. While, using other culture media at sametemperature and pH, gave low percentage of fertilization and higher yield of abnormal embryos.Thus, using Medicult IVF, Earl s and TCM-199 were gave fertilization percentages equivalent to38.75, 42.42 and 61.45% respectively; whereas, the percentages of abnormal embryos were 32, 35.7and 33.89 % respectively.The reported results indicate that composition of various types of culture media have significanteffect on the rate of fertilization and abnormal embryos.
