Purpose: in order to maintain the gonadal function after oophorectomy, morphofunctional aspects of ovarian autotransplantation to the greater omentum and the best kind of implantation, intact or sliced, were investigated. Methods: forty cycling female Wistar rats were randomly divided into four groups: Group I (n = 5), control - laparotomy; Group II (n = 5), bilateral oophorectomy; Group III (n = 10), intact ovarian autotransplantation to the greater omentum; and Group IV (n = 10), sliced ovarian autotransplantation, both to the greater omentum. The estrous cycle was investigated in the third and sixth postoperative months and histological studies of the ovarian implants were carried out considering: degeneration, fibrosis, inflammatory reaction, angiogenesis, follicular cysts, follicular development and corpora lutea. Results: the animals of Group I preserved the cycling sequence. The rats of Group II remained in diestrus. In Group III, 11 rats remained in diestrus, three presented incomplete cycles and one showed normal cycle. In Group IV, three animals remained in diestrus, eight showed incomplete cycles and four showed normal cycles. The histology of the ovaries of Group III was normal in ten female rats; however, the ovaries of the other five animals presented degeneration. In Group IV, 14 female rats had ovaries with preserved morphological aspect, and signs of degeneration occurred in one. Conclusions: the ovarian autotransplantation to the greater omentum is viable and the sliced form presented better morphofunctional aspects than the intact implants.
