Abstract
It has been found that caprine sperm factor, alone or in combination with adenophostin A, produces the Ca2+ oscillations characteristic of egg activation seen with fertilization. The introduction of caprine sperm factor and adenophostin A to eggs to produce reconstructed embryos has been optimized.
