Abstract Purpose: The aim of this study was to investigate the effects of vitamin E (Vit E) and vitamin C (Vit C) on oxidant-antioxidant system markers, ovarian follicle reserves, and surface epithelium in autologous intraperitoneal ovarian transplantation in rats.Materials and Methods: 20 adult female Wistar Albino were randomly divided into four groups. Group 1 (n = 5), the control group, only had their abdomens opened and closed. Group 2 (n = 5): underwent an ovarian transplantation. Group 3 (n = 5) received 20 mg/kg of intraperitoneal (IP) Vit E 15 minutes before an ovarian transplantation. Group 4 (n = 5) received 50 mg/kg of IP Vit C that was administered 15 minutes before an ovarian transplantation.Vaginal cytology was performed to monitor the oestrus phase. Biochemically, tissue and serum malondialdehyde levels and erythrocyte superoxide dismutase (SOD) levels were measured. Histopathologically, the number dysplastic changes in the ovarian surface epithelium were examined. Results: Dysplastic changes in the surface epithelium of Group 2 were found to be significantly higher than in Group 1 and 4 (p < 0.02). In Group 2, the ovarian follicle reserves were significantly lower than in other groups (p < 0.02). In addition, a significant decrease in SOD levels was found in Group 2 compared to other groups (p < 0.02). Conclusion: The study showed that Vit E and Vit C in autologous intraperitoneal ovarian transplantation preserved the ovarian follicle reserve. Vit C was found to be more effective than Vit E.

Dr. А. К. Sofoterow (Samara). Zur Frage liber die Transplantation des Eierstockes in die Uterushohle. Der Verfasser machte diese Operation bei 3 Kranken, wobei bei einer ein Teil des Eierstockes frei transplantiert wurde, bei zwei anderenan einem pedunculus. Zwei von diesen Kranken menstruieren (die eine wah rend 910 Monate, die andere5 Monate), die dritte hat vor Kurzem Klinik verlassen.

Homoplastic ovarian transplantation is recommended by Sippel (Zntrlb. F. Gyn., 1924, No. 1-2) in the treatment of infertility, which is based on disorders and irregularities in egg maturation processes with a tendency to premature rupture of follicles, followed by atresia or small cyst-like degeneration.

Abstract Study question Does autologous bone marrow derived stem cell (BMDSC) ovarian transplantation optimize ovarian reserve parameters in young infertile women with diminished ovarian reserve (DOR) ? Summary answer The autologous stem cell ovarian transplantation (ASCOT) improves AFC and AMH by facilitating the recruitment of existing dormant follicles in young women with DOR. What is known already Oocyte donation is the practical therapeutic option when patients with premature ovarian ageing desire pregnancy. It involves significant psychological burden in terms of not able to have their own biological child. ASCOT has opened new doors in poor responders and premature ovarian insufficiency through its beneficial effects on ovarian reserve and IVF outcomes. However recent studies have shown contradictory results in terms of its efficacy. No prior study has been contemplated in DOR group Study design, size, duration An open label non randomized controlled trial was conducted at Division of Reproductive Medicine in collaboration with stem cell facility at tertiary care institute. Forty two infertile women less than 35 years age with DOR (AFC&lt;5, AMH&lt;1.2ng/ml and /or high FSH&gt;8IU/l) were enrolled in the study during a period from January 2020 to December 2020. 20 women who did not opt for the intervention were treated as control group whereas 22 women received the intervention. Participants/materials, setting, methods Baseline hormonal profile ( Day 2 FSH, estradiol, AMH and AFC) was done in all patients. Women with abnormal uterine cavity, endometriosis, prior ovarian surgery, abnormal karyotype were excluded. Bone marrow aspiration followed by mesenchymal stem cells isolation was performed. The stem cells were transplanted in both the ovaries through transvaginal route on the same day. Follow up visits were planned at one and six months to assess ovarian reserve parameters. Main results and the role of chance The mean age, BMI and duration of infertility were comparable between the control and study group (29.5±3.34vs 29.36±2.95years, 21.51±1.40vs21.87±1.93kg/m2, 6.9±1.94vs7.04±3.67 years). The positive response in terms of improved AMH and AFC was seen in 68% (15/22) patients. The mean number of stem cells injected in these women were 77.71±25.33 million. At first follow up, there was no significant difference between mean FSH, estradiol levels and mean right and left ovarian volume (9.23±3.95 vs 9.02±3.92mIU/l, 61.46±29.25 vs 68.12±62.52 pg/ml, 2.82±2.18 vs 2.44±1.25 cc, 2.02±1.54 vs 2.72±1.06 cc, p &lt; 0.05). There was significant increase in AMH and AFC values as compared to baseline (0.79±0.43 vs 1.26±0.82ng/ml, p = 0.03; 3.47±1.30 vs 6.40±2.23, p &lt; 0.001). At second follow up visit, the significant increase in ovarian reserve persisted for AMH and AFC (0.79±0.43 vs 1.22±0.76 ng/ml, p = 0.02; 3.47±1.30 vs 6.93±1.71,p&lt;0.001). There was no significant difference between serum FSH, Estradiol and ovarian volume. None of the patients developed any complication and the improvement in AFC and AMH persisted during 10 month follow up period. Limitations, reasons for caution The limitation of present study is small sample size and non randomization. However, time period for which positive effect lasts has not been documented in earlier studies. This study is currently being endeavored, and women with improved ovarian reserve are followed up for any spontaneous conception or following assisted reproduction. Wider implications of the findings The present study demonstrates beneficial role of stem cells in improving ovarian reserve parameters in women with DOR with no acquired cause. If supported by future randomized clinical studies, it could represent a paradigm shift for fertility treatment in these women providing an opportunity to have their own biological child Trial registration number CTRI/2020/01/022726
