ABSTRACT
The oocyte-cumulus complex (25 oocytes per 250 microL medium) produced prostaglandin-F2 alpha (PGF2 alpha) and PGE2 during maturation, immediately following fertilization and for at least 48 h after fertilization. The data suggest that PG production is important in the development of the oocyte; addition of PGE2 (5 ng mL-1) to the fertilization medium increased the rate of cleavage and groups of oocytes with low cleavage rates produced far less PG than groups with high cleavage rates. Measurement of PG in the maturation medium could therefore be a means of assessing the suitability of oocytes for fertilization.
