although these two groups of oocytes were at the metaphase of the second meiosis , there were quantitative differences between the two with respect to ( i ) sensitivity of cumulus matrix to hyaluronidase and spermatozoa ( oviductal greater than ovarian ) , ( ii ) size of the perivitelline space ( oviductal greater than ovarian ) , ( iii ) viscosity of the ooplasm ( ovarian greater than oviductal ) , ( iv ) responsiveness to ca2+-ionophore ( oviductal greater than ovarian ) , and ( v ) time needed in completing meiosis ( ovarian greater than oviductal ) .
