Oocyte IVM is a long process during which oocytes acquire their ability to support the stages of development in a stepwise manner, ultimately reaching activation of the embryonic genome. The overall success of this process can be affected by factors

Laparoscopic oocyte recovery (LOR) is a valuable tool for obtaining oocytes for in vitro embryo production. When preceded by a treatment of ovarian stimulation, this technique produces an increase in the amount of oocytes recovered. However, a little
