Results using medium supplemented with either fresh or frozen stored serum in human in vitro fertilization.
This study retrospectively compared the success of in vitro fertilization (IVF) among patients whose gametes had been incubated either in medium supplemented with freshly prepared pooled serum (331 cases) or in pooled serum which had been stored at -20 degrees C prior to use (728 cases). Frozen stored serum was as effective as fresh serum with regard to the proportion of oocytes which fertilized and embryos which implanted and was not associated with any increased incidence of fetal loss during postimplantation development.
