These studies were carried out to investigate the effects of fetal calf serum(FCS), estrous porcine serum(EPS), porcine follicular fluid(PFF), hormone and matured cumulus cell(MCC) on in vitro maturation and fertilization of porcine follicular oocytes. The ovaries and testes were obtianed from slaughtered Landrace sow and boars, respectively. The follicular oocytes surrounded with cumulus cells were recovered by aspirating follicular fluid from the visible follicles of diameter 3~5 mm and the semen were prepared from boar's epididymal cauda. The follicular oocytes were cultured in TCM-199 medium containing hormones, FCS, EPS, PFF and MCC for 48hrs. in a incubator with 5% CO2 in air at 36$^{\circ}C$ and then matured oocytes were again cultured for 18~20 hrs. with $1.5\times$106/ml motile capacitated sperm in the modified Tyroide solution containing 100$\mu\textrm{g}$/ml of heparin. The results obtained in these experiments were summarized as follows : 1. The maturation and fertilization rate of the follicular oocytes, cultured in the TCM-199 medium supplemented with 10% FCS and PMSG+HCG were 55.6~64.5% and 33.3~37.1%, respectively. 2. The maturation and fertilization rate of the follicular oocytes cultured in the TCM-199 medium supplemented with 20% EPS and PMSG+HCG were 50.0~55.0% and 30.3~33.3%, respectively. 3. The maturation rate(59.0~64.2%) and fertilization rate(34.8~39.3%) of follicular oocytes cultured in TCM-199 medium supplemented 20% FCS and 50% PFF were higher than those of follicular oocytes cultured in TCM-199 medium supplemented with 5%, 10% and 15% FCS and 10% and 50% PFF. 4. The maturation rate(60.0%) and fertilization rate(40.0%) of follicular oocytes cultured in TCM-199 medium supplemented with 20% FCS and granulosa cell (1$\times$106/ml) were significantly higher than those of fiollicular oocytes cultured in TCM-199 medium supplemented with 5%, 10% and 15% FCS and granulosa cell.
