Cryopreservation of ovarian tissue in advance of cytotoxic therapies and later transplantation of the tissue is being performed increasingly often, and the total success rates in terms of pregnancy and delivery have been described in case series. Most pregnancies were achieved after orthotopic transplantation of tissue (in the peritoneum or the remaining ovary); however, treatment of the transplantation site during surgery is controversial. In this observational case-series study, we include four patients who underwent ovarian tissue transplantation between 2012 and 2016 by laparoscopy. Previously ovarian tissue was cryopreserved with slow freezing protocol prior to chemo- and/or radiotherapy. After cancer remission, the cryopreserved ovarian tissues were orthotopically re-transplanted in the ovarian medulla by laparoscopy, using N-hexyl-2-cyanoacrylate as an absorbable adhesion barrier. All patients regained ovarian function between 8 and 24 weeks after transplantation, as shown by follicle development and estrogen production. In patients 1 and 2 the ovarian function ended one year after transplantation. Patient 3 has regular menstrual cycles 2 years after the transplant and patient 4 currently has an ongoing spontaneous pregnancy.
The use of N-hexyl-2 cyanoacrylate can facilitate the placement of ovarian pieces in orthotopic transplantation by laparoscopy without affecting the restoration and duration of ovarian activity.
