Occurrence and developmental consequences of aberrant cellular organization in meiotically mature human oocytes after exogenous ovarian hyperstimulation

Abstract excerpt

The extent to which fertilization failure in in vitro inseminated human oocytes obtained from hyperstimulated ovaries was associated with alterations in cellular structure and cytoplasmic organization was examined by a combination of DIC, fluorescence, time-lapse video, and transmission electron microscopy. Detailed analysis of meiotically mature preovulatory (uninseminated) oocytes, and of oocytes that failed to...
