The Second maturation division of the mammalian ovum occurs
shortly after ovulation before the ovum makes entry into the fallopian tube
until after the ovum has been penetrated by a sperm
until the nucleus of the sperm has fused with that of the ovum
in the graafian follicle following the first maturation division
As we discussed in concept
Second Polar body -
This induces the completion of the meiotic division of the secondary oocyte. The second meiotic division is also unequal and results in the formation of a second polar body and a haploid ovum (ootid) .
