ABSTRACT
Recovery of more than one oocyte from a single follicle during laparoscopic egg collection has been reported sporadically and accepted as confirmation of the presence of polyovular or binovular follicles in the human ovary at reproductive age. Most of these reports include conjoined oocytes that share common or fused zona pellucida, and are generally accepted as evidence for true polyovularity due to its certain characteristics. In this study, we report one case of a conjoined oocyte and another case of the recovery of two separate oocytes in a cumulus cell complex and details of their early embryonic development. To our knowledge, this report of the recovery of two separate oocytes without zonal contact is the first in the literature. We reviewed the relevant literature to evaluate information regarding the origin, incidence and significance of polyovularity in reproductive health.
