There are a number of problems during the process of culture in vitro on fertilization and embryo development compared to those on in vivo counterparts. And the platelet activating factor (PAF), which is found not only in mammalian spermatozoa but also preembryos, is implicated on reproductive process. To improve the environment of culture on in vitro fertilization and embryo development, coculture using salpingeal epithelial cells has been considered to accept the better result on pregnancy rate. This study was designed to determine if two different culture systems, coculture alone and PAF treated coculture, are positive or negative influence on process of in vitro fertilization and embryo culture in mouse. The cell cleavage rate reached to 2-4 cell stage at 24 hours of culture is 56.81% (50/88) and 48.21%(54/112) respectively, in PAF treated group which is added PAF on coculture and in coculture group. But the rate of cells cleavage was similar in both group after 48 hours of culture. The rate of unfertilization after insemination of oocytes was higher in coculture group(55..53%) than in PAF treated group(42.37%). And in assessment of undeveped embryos, the rate of equalized cell block was similar on both, coculture alone (35.3%)and PAF treated coculture(35.5%). while unequalized cell block was higher rate in PAF treated coculture(19.4%) than coculture alone (11.8%). But the rate of cytoplasmic degeneration of undeveloped embryos was significantly higher in PAF treated coculture than coculture alone. In conclusion, we have observed that PAF treated coculture is superior in the rates of in vitro fertilization and early embryo cell cleavage compared to those in coculture alone, but there is no difference on the rates of embryo develpments, cell degeneration, cell quality in both PAF treated coculture and coculture alone when the embryo cells were continuosly cultured for 48 hours or more.
