Brown oocytes: implications for assisted reproductive technology.
Fertilization, embryo development, and successful pregnancy can be achieved after transfer of embryos derived from brown oocytes at the same rate as embryos from morphologically normal oocytes. Therefore, brown oocytes are probably normal and this morphological criterion does not seem to be indicative of any adverse outcome in IVF.
