Abstract

Nitric oxide adversely affects survival and development of cells such as oocytes and embryos in vitro, particularly in a co-culture system. The addition of a nitric oxide inhibitor such as hemoglobin to such systems eliminates this toxic effect, and promotes mammalian oocytes, embryos, or other cells in vitro.
