Introduction: The aim of this study is to report the current status of ovarian tissue cryopreservation among alternatives for fertility preservation in the Nordic countries., Material and Methods: A questionnaire was sent to 14 Nordic academic reproductive centers with established fertility preservation programs. It covered fertility preservation cases performed up to December 2014, standard procedures for ovarian tissue cryopreservation and oocyte cryopreservation and reproductive outcomes following ovarian tissue transplantation., Results: Among the Nordic countries, Denmark and Norway practice ovarian tissue cryopreservation as a clinical treatment (822 and 164 cases, respectively) and their programs are centralized. In Sweden (457 cases), ovarian tissue cryopreservation is practiced at five of six centers and in Finland at all five centers (145 cases). Nearly all considered ovarian tissue cryopreservation to be experimental. In Iceland, embryo cryopreservation is the only option for fertility preservation. Most centers use slow-freezing methods for ovarian tissue cryopreservation. Most patients selected for ovarian tissue cryopreservation were newly diagnosed with cancer and the tissue was predominantly retrieved laparoscopically by unilateral oophorectomy. Only minor complications were reported. In total, 46 women have undergone ovarian tissue transplantation aiming at recovering fertility, 17 healthy children have been born and several additional pregnancies are currently ongoing. Whenever patients' clinical condition is permissive, oocyte cryopreservation after hormonal stimulation is preferred for fertility preservation. Between 2012 and 2014, a smaller proportion of females have undergone fertility preservation in the Nordic centers, in comparison to males (1:3)., Conclusions: Overall, ovarian tissue cryopreservation was reported to be safe. Slow freezing methods are still preferred. Promising results of recovery of fertility have been reported in Nordic countries that have initiated ovarian tissue transplantation procedures., (© 2016 The Authors.

Objective: To explore oocyte and sperm donors' emotional stress, experiences of care and satisfaction after donation., Design: Prospective multicenter study., Settings: All fertility clinics performing gamete donation in Sweden during the period 2005 to 2008., Population: Of 220 eligible oocyte donors who were approached, 181 agreed to complete the first questionnaire and 165 completed the second questionnaire 2 months after oocyte donation. Of 156 eligible sperm donors 119 accepted to complete the first questionnaire before donation. Eighty-nine participants completed the second questionnaire 2 months after sperm donation., Methods: Standardized and study-specific questionnaires., Main Outcome Measures: Satisfaction with the donation, respondents' mental health and overall care., Results: A larger percentage of sperm donors (97.8%) were satisfied with their overall experience of being a donor than oocyte donors (85.9%, p = 0.003). Some oocyte and sperm donors did not receive sufficient information about practical issues (9.1% and 13.5%, respectively) and future consequences (12.8% and 3.4%, respectively, p = 0.014). The donors' symptoms of anxiety and depression did not show any differences in relation to negative or positive perceptions of satisfaction. The donors who did not indicate ambivalence before treatment were on average almost five times more satisfied compared with those who did indicate ambivalence (odds ratio 4.71; 95% CI 1.34-16.51)., Conclusions: Most donors were satisfied with their contribution after the donation. Oocyte and sperm donors who expressed ambivalence before donation were less satisfied after donation. In vitro fertilization staff fulfilled most of the donors' needs for information and care., (© 2013 The Authors.

Objective: To study donors' motivation and ambivalence before donation of gametes., Design: Cross-sectional study., Setting: Seven Swedish university hospital clinics. Sample. Of the 220 eligible oocyte donors and 156 eligible sperm donors who were approached, 181 (82%) oocyte donors and 119 (76%) sperm donors agreed to participate., Methods: Gamete donors completed a questionnaire in the clinic prior to the donation., Main Outcome Measures: Motives and ambivalence towards donation., Results: In general, gamete donors donated for altruistic reasons (95%). A greater percentage of oocyte than sperm donors had a personal experience of biological children, which motivated them to donate (65 vs. 32%). A greater percentage of sperm donors compared with oocyte donors were curious about their own fertility (24 vs. 9%), and they also believed that they were contributing what they regarded as their own good genes to other couples (45 vs. 20%). Prior to donation, potential sperm donors were more ambivalent towards donating than were oocyte donors (39 and 21%, p < 0.001)., Conclusions: The motives to donate gametes are mainly altruistic. We conclude that men and women differ in their view towards donating gametes. Sperm donors had a higher degree of ambivalent feelings towards donation than oocyte donors., (© 2012 The Authors Acta Obstetricia et Gynecologica Scandinavica© 2012 Nordic Federation of Societies of Obstetrics and Gynecology.)
