In flowering plants , the female gametophyte has been reduced to an eight-celled embryo sac within the ovule inside the ovary of the flower. In vitro maturation IVM is the technique of letting ovarian follicles mature in vitro. This is achieved by the process of meiosis. From Wikipedia, the free encyclopedia. As a result of meiosis I, the primary oocyte has now developed into the secondary oocyte and the first polar body. It can potentially be performed before an IVF. This recombination is associated with formation of DNA double-strand breaks and the repair of these breaks.
