Sometimes a sperm cell fertilizes a polar body rather than a secondary oocyte. An embryo does not develop, and the fertilized polar body degenerates. Why is a polar body unable to support development of an embryo?
A previously infertile couple wishes to have a pregnancy but the man produces non-motile sperm.If it were possible to fertilize one of the woman's eggs by removing a sperm nucleus and injectingit into the egg, could this procedure ever produce viable offspring? Why or why not?
