Abstract
OBJECTIVE The study investigated factors associated with successful intra-operative oocyte retrieval for fertility preservation during transabdominal gynecologic surgery. STUDY DESIGN A total of 29 patients who underwent intraoperative oocyte retrieval during staging surgery at a single academic hospital from May 2014 to August 2022 were enrolled in this study, and their outcomes were analyzed. RESULTS Among 29 patients who underwent intra-operative oocyte retrieval during staging surgery, oocytes were obtained in 24 patients, representing 82.8 % of the retrieval rate (24/29), and two patients returned to use cryopreserved oocytes (6.9 %). Among 24 women who succeeded in obtaining oocytes, 20 patients succeeded in oocyte cryopreservation, and two patients proceeded to embryo cryopreservation. The cryopreservation rate was 91.7 % (22/24). All patients with failed oocyte retrieval (n = 5) and cryopreservation (n = 7) were diagnosed with malignancy. AMH of those with successful cryopreservation oocytes was higher than those without cryopreservation (4.10 ng/mL vs. 1.18 ng/mL, p = 0.003). A higher portion of the unstimulated cycle was observed in those with failed cryopreservation (8.3 % vs. 40.0 %, p = 0.01). No complications were noted. CONCLUSION For women planning to undergo open pelvic surgery, intra-operative oocyte retrieval is a feasible option. High serum AMH and ovarian stimulation before surgery may predict successful oocyte cryopreservation.

In Vitro Maturation of Oocytes Obtained from Ovarian Cortex Among Postpubertal Hematological Cancer Patients Undergoing Fertility Preservation. J Adolesc Young Adult Oncol 2024. [PMID: 39058661 DOI: 10.1089/jayao.2023.0157] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 07/28/2024] Open
Abstract
Purpose: In vitro maturation (IVM) of oocytes obtained from ovarian tissue during ovarian tissue cryopreservation (OTC) is a technique for fertility preservation in patients with cancer obviating the need to postpone chemotherapy initiation. Little is known about IVM outcomes in hematological malignancies, especially post-chemotherapy. The purpose of this study was to evaluate the effect of cytotoxic treatment on the potential to retrieve immature oocytes and mature them in vitro and examine the association between serum inflammatory markers and these results. Methods: In this retrospective study, we evaluated inflammation markers, including B symptoms and IVM outcomes of 78 chemotherapy-naive and exposed patients diagnosed with Hodgkin lymphoma (HL), non-Hodgkin lymphoma (NHL), acute lymphoblastic leukemia (ALL), or acute myeloid leukemia (AML). Results: The mean number of oocytes found was 7.2 ± 7.2. The average number of oocytes matured by IVM was 2.8 ± 3.5, and a mean IVM rate was 32.1 ± 27.7%. All patients in the ALL and AML groups had previous exposure to chemotherapy before OTC, compared with 50.0% (7/14) and 31.9% (15/47) in the NHL and HL groups, respectively. Among patients with lymphoma, chemotherapy exposure was associated with the reduced number of retrieved oocytes (9.8 ± 7.7 vs. 5.3 ± 5.7 oocytes, p = 0.049) in the HL group but not with the number of mature oocytes or IVM rate. B symptoms were not associated with IVM outcomes. Lymphocyte count (ß = 1.584; p = 0.038) and lactate dehydrogenase (ß = 0.009; p = 0.043) were the only significant parameters associated with the number of matured oocytes in a linear regression model. Conclusion: IVM is a promising assisted reproductive technology, which holds great potential for patients in need of urgent fertility preservation or those who cannot receive hormonal stimulation. Our results demonstrate the feasibility of the technique even in the presence of B symptoms and elevated inflammation markers and in patients with previous exposure to chemotherapy.

Abstract
OBJECTIVE To report pregnancy and live birth resulting from intracytoplasmic sperm injection of ex vivo-retrieved mature oocytes from a woman with bilateral ovarian carcinoma. DESIGN Case report. SETTING Fertility clinic. PATIENT A 34-year-old nulliparous woman with bilateral ovarian tumor, with a risk of malignancy of 96.1% according to International Ovarian Tumor Analysis Group recommendations for adnexal tumors, who desired fertility preservation before definitive surgical treatment. INTERVENTION(S) Cryopreservation of ex vivo-retrieved mature metaphase II oocytes is followed by fertilization with donor sperm and embryo transfer to a gestational carrier. MAIN OUTCOME MEASURE(S) Fertility preservation. RESULTS After controlled ovarian stimulation, 12 metaphase II oocytes were retrieved from oophorectomized specimens and vitrified. Intracytoplasmic sperm injection with donor sperm was performed in remission, resulting in 9 cleavage-stage embryos, 2 of which were transferred to a gestational carrier, resulting in a normal, healthy singleton pregnancy, and the live birth of a healthy infant. CONCLUSION(S) Ex vivo oocyte retrieval after oophorectomy may be a safe alternative to standard oocyte retrieval for fertility preservation in women with ovarian malignancies.

Abstract
Geographically distributed ovarian tissue cryobanks remain limited due to the high facility and staff costs, and cold transportation to centers is associated with ischemia-induced tissue damage that increases with transport distance. It is ideal to perform the cryopreservation procedure at a tissue removal site or local hospital before shipment to cost-effective centralized cryobanks. However, conventional liquid nitrogen-based freezers are not portable and require expensive infrastructure. To study the possibility of an ovarian tissue cryopreservation network not dependent on liquid nitrogen, we cryopreserved bovine ovarian tissue using three cooling techniques: a controlled rate freezer using liquid nitrogen, a liquid nitrogen-free controlled rate freezer, and liquid nitrogen-free passive cooling. Upon thawing, we evaluated a panel of viability metrics in frozen and fresh groups to examine the potency of the portable liquid nitrogen-free controlled and uncontrolled rate freezers in preserving the ovarian tissue compared to the non-portable conventional controlled rate freezer. We found similar outcomes for reactive oxygen species (ROS), total antioxidant capacity (TAC), follicular morphology, tissue viability, and fibrosis in the controlled rate freezer groups. However, passive slow cooling was associated with the lowest tissue viability, follicle morphology, and TAC, and the highest tissue fibrosis and ROS levels compared to all other groups. A stronger correlation was found between follicle morphology, ovarian tissue viability, and fibrosis with the TAC/ROS ratio compared to ROS and TAC alone. The current study undergirds the possibility of centralized cryobanks using a controlled rate liquid nitrogen-free freezer to prevent ischemia-induced damage during ovarian tissue shipment.

Abstract
PURPOSE To identify patient characteristics associated with successful isolated immature oocyte retrieval (IsO) during ovarian tissue cryopreservation (OTC) and to determine whether they are predictive of the collection of larger numbers of oocytes. METHODS We retrospectively analyzed all patients undergoing OTC with IsO for fertility preservation over three years of activity at a university hospital. Univariate and multivariate analyses were used to identify the patients with the highest and lowest chances of oocyte recovery, and those with the largest numbers of oocytes. We also analyzed the correlation of IsO with the number of ovarian fragments collected and histological parameters. RESULTS We analyzed 257 consecutive patients undergoing these procedures, at a median age of 17.1 years [0.3-38.3 years]. Isolated oocytes were obtained from 47.1% of patients, and IsO was more likely in patients with ovulatory cycles (63.0% vs. 38.6%; P≤ .001), without chemotherapy before OTC (61.4% vs. 33.1; P< .001) and with non-malignant diseases other than Turner syndrome (77.5%). Oocyte collection failure rates were highest in patients with Turner syndrome (OR 25.0, 95% CI 3.99-157.0; P< .001) or undergoing chemotherapy with alkylating agents before OTC (OR 37.6, 95% CI 8.36-168.8; P< .001). Prepubescent status (P= .043) and large numbers of ovarian fragments (P< .001) were associated with the retrieval of larger numbers of oocytes. Oocyte recovery was correlated with the presence of follicles in the medulla, but not with follicular density. CONCLUSION The chances of IsO differ between patients. Identifying patients with the highest chances of success facilitates appropriate resource allocation.

Abstract
Ovarian tissue oocyte (OTO) in vitro maturation (IVM) is a strategy to improve fertility preservation efficiency. Here, the effects of capacitation IVM (CAPA-IVM) on OTO function were investigated. Immature cumulus-oocyte complexes (COCs) from unstimulated 28-day-old mouse ovaries (mimicking OTOs) underwent CAPA-IVM, standard IVM (S-IVM) or in vivo maturation following ovarian stimulation (OS; positive control), and oocyte meiotic maturation and cytoplasmic quality were assessed. CAPA-IVM resulted in improved oocyte meiotic maturation (P < 0.05) and cumulus expansion (P < 0.0001) compared to S-IVM, with expansion comparable to the OS group. MII OTO ROS was lower after CAPA-IVM than S-IVM (P < 0.0001) but not as low as in the OS group (P = 0.036). CAPA-IVM resulted in a better oocyte mitochondrial distribution than S-IVM (P < 0.05) and was similar to the OS group (P > 0.05). Mitochondrial membrane potential in MII OTOs was higher after CAPA-IVM than S-IVM and OS (P < 0.0001). Compared with S-IVM, CAPA-IVM resulted in lower rates of spindle/chromosome configuration and cortical granule distribution abnormalities (P < 0.05), which were similar to OS levels (P > 0.05). MII OTO intracellular Ca2+ levels were similar in the CAPA-IVM and OS groups (P > 0.05), while S-IVM decreased intracellular Ca2+ (P < 0.05). CAPA-IVM and S-IVM decreased mitochondrial Ca2+ levels (P < 0.05). CAPA-IVM increased expression of antioxidant genes (Sod2 and Sirt1) and Egfr (P < 0.05) but not apoptotic genes (Bcl2, Bax and Bcl2/Bax; P > 0.05). CAPA-IVM increased the OTO maturation rate and quality of oocytes from unstimulated mice to the extent that many features of oocyte cytoplasmic quality were comparable to superovulated in vivo matured oocytes.

Bourg M, Moreau J, Carles M, Cadoret F, Lesourd F, Tournier A, Léandri RD, Gatimel N. Is in vitro maturation of oocytes retrieved ex vivo from ovarian tissue an effective fertility preservation technique in the presence of organic ovarian cysts? Eur J Obstet Gynecol Reprod Biol 2023; 281:87-91. [PMID: 36586210 DOI: 10.1016/j.ejogrb.2022.12.025] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/29/2022] [Revised: 07/21/2022] [Accepted: 12/24/2022] [Indexed: 12/28/2022]
Abstract
OBJECTIVE(S) In vitro maturation (IVM) of oocytes retrieved ex vivo from ovarian tissue (OTO-IVM) could be an additional source of mature oocytes with the potential to optimise medical fertility preservation (FP) after oophorectomy. It is often undertaken at the same time as the ovarian tissue cryopreservation (OTC). In the presence of an organic ovarian cyst, OTO-IVM could prove to be the only technique available to permit FP since ovarian stimulation, transvaginal ovarian needle puncture or future ovarian tissue graft are contraindicated. However, the presence of an organic cyst could alter follicular growth and the number of retrievd oocytes. Our study aims to assess the efficiency of OTO-IVM in such situations. STUDY DESIGN Retrospective, observational study involving 20 female patients with FP by OTO-IVM between May 2017 and November 2021 at the University Hospital of Toulouse. Oocytes retrieved "ex vivo" were transferred to an IVM medium with HP-hMG, LH and HSA and then vitrified after 24 to 48 h of IVM. Data analysis was performed on the total population and comparatively between patients who had or did not have an organic ovarian cyst. RESULTS The indications included 15 oncologic and 5 non-oncologic indications. Ten had an organic ovarian cyst on the retrieved ovary. The number of retrieved oocytes was 17.4+/-12.0 in the absence of cyst vs 4.1+/-6.3 in the presence (p = 0.003). The number of vitrified mature oocytes was 5.8+/-5.3 in the absence vs 1.1+/-2.2 (median = 0) in the presence of a cyst (p = 0.03). Ninety percent of the patients with an organic cyst had less than two vitrified mature oocytes. The mean maturation rate was 34%, not significantly different between the two groups. We found a correlation between serum AMH level and the number of mature oocytes: ρ:0.47 CI95 = [0.02; 0.76]; p = 0.04. CONCLUSION(S) OTO-IVM is an additional source of mature oocytes to optimise FP after oophorectomy. However, in the presence of an organic ovarian cyst on the retrieved ovary, the exocrine, paracrine and endocrine functions of the ovary are impaired. As such, the number of immature oocytes obtained is highly impacted and appears to be insufficient to be able to propose systematically this technique in such situations.

Abstract
In vitro maturation (IVM) of transvaginally aspirated immature oocytes is an effective and safe assisted reproductive treatment for predicted or high responder patients. Currently, immature oocytes are also being collected from the contralateral ovary during laparoscopy/laparotomy and even ex vivo from the excised ovary or the spent media during ovarian tissue preparation prior to ovarian cortex cryopreservation. The first live births from in vitro-matured ovarian tissue oocytes (OTO-IVM) were reported after monophasic OTO-IVM, showing the ability to achieve mature OTO-IVM oocytes. However, fertilisations rates and further embryological developmental capacity appeared impaired. The introduction of a biphasic IVM, also called capacitation (CAPA)-IVM, has been a significant improvement of the oocytes maturation protocol. However, evidence on OTO-IVM is still scarce and validation of the first results is of utmost importance to confirm reproducibility, including the follow-up of OTO-IVM children. Differences between IVM and OTO-IVM should be well understood to provide realistic expectations to patients.

Abstract
Oocyte in vitro maturation (IVM) is a technology with a long history that was established before IVF. Although it has been studied extensively, the efficiency of IVM has been poor for almost 30 years. In terms of the benefits of IVM, the efficiency and adoption of IVM are being improved by some notable improvements that have occurred in recent years. The establishment of biphasic IVM is the most important advancement in recent years. Biphasic IVM includes the pre-IVM culturing phase and IVM phase. The CNP-mediated pre-IVM culturing system is specifically tailored for non/minimally stimulated immature oocytes, and its efficiency has been shown. This is the most significant improvement made in recent decades in this area. In the clinic, IVM can be used for PCOS patients to avoid the occurrence of ovarian hyperstimulation syndrome (OHSS). Additionally, this method can solve the reproductive problems of some patients with special diseases (resistant ovary syndrome) that cannot be solved by IVF. In most fertility preservation procedures, oocytes in small antral follicles are lost. However, IVM has the ability to capture this kind of oocyte and save reproductive potential. IVM can be easily combined with fertility preservation strategies that have been applied in the clinic and improve the efficiency of fertility preservation. IVM is a useful and attractive technology and may be used widely worldwide in the near future.

Abstract
Ovarian cancer is more frequent in post-menopausal women, however it can also occur in young premenopausal women. After diagnosis and cancer staging, health care providers should address the possibility of infertility and might offer fertility preservation options. Chemotherapy, frequently used when treating ovarian cancer, has proven to cause extensive ovarian damage. Standard surgery may be aggressive and the recurrence risk may not be relevant enough to opt for these approaches. Fertility sparing surgery has been progressively accepted and many alternative surgical approaches have proven to be successful in both cancer treatment, fertility preservation and low recurrence rates. Though there are several techniques available for fertility preservation in cancer patients, when dealing with ovarian cancer patients, oocyte and embryo cryopreservation are the only suitable. Ovarian tissue cryopreservation has been largely studied, but no data on ovarian cancer patients exist, due to the risk of reimplanting cancer cells.

Successful in vivo retrieval of oocytes after ovarian stimulation for fertility preservation before oophorectomy by laparotomy for a young patient with ovarian cancer: Case report and review of literature. Gynecol Oncol Rep 2021; 37:100791. [PMID: 34095426 PMCID: PMC8167225 DOI: 10.1016/j.gore.2021.100791] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/25/2021] [Revised: 04/12/2021] [Accepted: 05/16/2021] [Indexed: 11/22/2022] Open
Abstract
Mature oocytes can be retrieved in-vivo during open surgery for gynecologic cancers. This approach should be considered when transvaginal access is contra-indicated. The technique is feasible, safe and avoids any time of ischemia for gametes.
Objective To report a case of direct in vivo oocytes retrieval for fertility preservation before oophorectomy by open surgery in a young patient with ovarian cancer. Design case report and literature review. Setting University hospital. Patients A 29-year-old nulliparous patient, recently diagnosed with low grade serous ovarian carcinoma. The patient consented to the removal of her remaining ovary but wished to preserve oocytes and declined hysterectomy. Conventional trans-vaginal US-guided oocyte retrieval was contra-indicated because of the risk of malignant cell dissemination to the abdomen and the vaginal puncture sites. Interventions Controlled ovarian stimulation with gonadotrophins was realized. Comprehensive surgical staging was performed 35 h after ovulation triggering using rHCG. The oocytes retrieval was performed in vivo with ultrasound guidance at time of laparotomy before oophorectomy without any time of ischemia. Results Seven mature oocytes were obtained and vitrified. Conclusions This case highlights the feasibility of in vivo oocytes retrieval of mature oocytes during open surgery for gynecologic cancers. By avoiding transvaginal follicular retrieval, the risk of malignant cell contamination to vaginal and parametrial tissues is reduced, limiting cancer upstaging.

Abstract
STUDY QUESTION Can oocytes extracted from excised ovarian tissue and matured in vitro be a useful adjunct for urgent fertility preservation (FP)? SUMMARY ANSWER Ovarian tissue oocyte in-vitro maturation (OTO-IVM) in combination with ovarian tissue cryopreservation (OTC) is a valuable adjunct technique for FP. WHAT IS KNOWN ALREADY Despite the impressive progress in the field, options for FP for cancer patients are still limited and, depending on the technique, clinical outcome data are still scarce. STUDY DESIGN, SIZE, DURATION This was a retrospective cohort study conducted at a university hospital-affiliated fertility clinic between January 2012 and May 2019. PARTICIPANTS/MATERIALS, SETTING, METHODS The study included 77 patients who underwent unilateral oophorectomy for OTC. Cumulus-oocyte complexes (COCs) obtained during ovarian tissue processing were matured in vitro for 28-42 h. Oocytes reaching metaphase II stage were vitrified or inseminated for embryo vitrification. MAIN RESULTS AND THE ROLE OF CHANCE Overall, 1220 COCs were collected. The mean oocyte maturation rate was 39% ± 23% (SD). There were 64 patients who had vitrification of oocytes (6.7 ± 6.3 oocytes per patient). There were 13 patients who had ICSI of mature oocytes after IVM, with 2.0 ± 2.0 embryos vitrified per patient. Twelve patients have returned to the clinic with a desire for pregnancy. For seven of these, OTO-IVM material was thawed. Two patients had OTO-IVM oocytes warmed, with survival rates of 86% and 60%. After ICSI, six oocytes were fertilised in total, generating three good quality embryos for transfer, leading to a healthy live birth for one patient. In five patients, for whom a mean of 2.0 ± 0.8 (SD) embryos had been vitrified, seven embryos were warmed in total: one embryo did not survive the warming process; two tested genetically unsuitable for transfer; and four were transferred in separate cycles to three different patients, resulting in two healthy babies. In this small series, the live birth rate per patient after OTO-IVM, ICSI and embryo transfer was 43%. LIMITATIONS, REASONS FOR CAUTION The retrospective study design and the limited sample size should be considered when interpreting results. WIDER IMPLICATIONS OF THE FINDINGS The results of the study illustrate the added value of OTO-IVM in combination with OTC. We report the first live birth following the use of this appended technique combined with oocyte vitrification. STUDY FUNDING/COMPETING INTEREST(S) No external funding was used for this study. M.D.V. reports honoraria for lectures in the last 2 years from MSD and Ferring, outside the submitted work, as well as grant support from MSD. The other authors have nothing to declare.

Low feasibility of in vitro matured oocytes originating from cumulus complexes found during ovarian tissue preparation at the moment of gender confirmation surgery and during testosterone treatment for fertility preservation in transgender men. Fertil Steril 2021; 116:1068-1076. [PMID: 33832736 DOI: 10.1016/j.fertnstert.2021.03.009] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/02/2020] [Revised: 03/05/2021] [Accepted: 03/05/2021] [Indexed: 11/25/2022]
Abstract
OBJECTIVE To study the feasibility of in vitro maturation of ovarian tissue oocytes for fertility preservation in transgender men on testosterone treatment. DESIGN Cross-sectional study SETTING: University hospital PATIENT(S): Eighty-three transgender men enrolled from November 2015 to January 2019 INTERVENTION(S): In vitro maturation of cumulus-oocyte complexes (COCs) harvested at the time of gender confirmation surgery, and fertilization through intracytoplasmic sperm injection. MAIN OUTCOME MEASURE(S) In vitro maturation, fertilization, and blastulation rates; comparison of morphokinetics with vitrified-warmed oocytes; and analysis of the genetic profiles of embryos. SECONDARY OUTCOMES association between serum hormone levels; COCs' morphologic characteristics, and vitrification rate. RESULT(S) All participants were on testosterone treatment for a median of 83 (64[Quartile 1]; 113.2[Quartile 2]) weeks. A total of 1,903 COCs (mean per participant, 23 ± 15.8) were collected. The in vitro maturation rate was 23.8%, vitrification rate was 21.5%, and survival rate after warming was 72.6% (n = 151). Intracytoplasmic sperm injection was performed in 139 oocytes. The rate of normal fertilized oocytes was 34.5%, and 25 (52.1%) embryos reached day 3. One blastocyst was achieved on day 5. Aberrant cleavage patterns and early embryo arrest were observed in 22 (45.8%) and 44 (91.7%) zygotes, respectively. Compared with vitrified-warmed donor oocytes, a delay was observed in pronuclei disappearance, t2 (time to reach 2 cell stage) timings, and CC1 (the duration of the 1st cell cycle) and SS3 (synchronization of cleavage pattern (calculated as t8-t5) time intervals. A normal genetic pattern was seen in 42% embryos. The proportion of vitrified oocytes was negatively associated with progesterone (odds ratio, 0.76) and positively associated with antimüllerian hormone serum levels (odds ratio, 1.23). The highest vitrification rate was achieved by the morphologic characteristic 344 at day 0 and by 433 at day 2. CONCLUSION(S) Ovarian tissue oocytes matured in vitro show low developmental capacity in transgender men, when collected under testosterone treatment.

Feasibility of in vitro maturation of oocytes collected from patients with malignant ovarian tumors undergoing fertility preservation. Int J Gynecol Cancer 2021; 31:475-479. [PMID: 33649016 DOI: 10.1136/ijgc-2020-001754] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/11/2020] [Revised: 12/14/2020] [Accepted: 12/16/2020] [Indexed: 11/04/2022] Open
Abstract
OBJECTIVE In vitro maturation of oocytes collected from oophorectomy samples might be a promising approach in the field of oncofertility. In this study, we evaluate the feasibility of in vitro maturation of oocytes collected from oophorectomy samples in patients with ovarian tumors. METHODS This prospective observational study included 27 patients with malignant ovarian tumors. Patients underwent oophorectomy and ovarian tissue was examined for the presence of immature cumulus-oocyte complexes. These were matured in vitro for 48 hours. Mature oocytes were vitrified or used for fertilization. Serum anti-müllerian hormone (AMH) levels were analyzed in 11 patients and cancer antigen 125 (CA125) levels in 16 patients. RESULTS In this study, 99 cumulus-oocyte complexes were obtained from 17 patients (63%). The mean (SE) age of the patients was 33.47±1.86 years (range 16-44). A total of 14 patients had ovarian cancer (IA-IVB), one patient had ovarian cancer IC and endometrial cancer IA, one patient had endometrial cancer stage IA with metastasis into the ovary, and one patient had cervical cancer stage IIB with metastasis in the ovary. Oocytes were not obtained in 10 patients who had diminished ovarian reserve due to age (>38 years), chemotherapy, or previous surgical treatment. On average, 5.8 cumulus-oocyte complexes were obtained per patient. The maturation rate was 40.4% with an average of 2.8 metaphase II oocytes per patient. As a result of the study, 3 blastocysts in 3 patients and 22 oocytes in 9 patients were vitrified. CONCLUSIONS In vitro maturation of oocytes collected from oophorectomy samples in patients with malignant ovarian tumors may result in oocyte and blastocyst vitrification. However, it should be offered to patients before surgery and chemotherapy. This method might be most beneficial in patients younger than 38 years, with AMH serum levels >1 ng/mL and without a large tumor burden.

Abstract
PURPOSE To investigate the developmental competence of ovarian tissue oocytes from patients with gynecological tumors using a biphasic in vitro maturation system with capacitation (CAPA-IVM) in comparison with standard IVM. METHODS This sibling pilot study included 210 oocytes in 10 patients with gynecological malignancies. After ovariectomies, ovaries were cut into even halves and immature cumulus-oocyte complexes (COCs) were retrieved from the ovarian tissue. COCs were separately cultured in either a biphasic CAPA-IVM system for 53 h or in standard IVM for 48 h. After IVM, all COCs were denuded and mature oocytes were either vitrified (N=5) or used for ICSI (N=5). Embryos were cultured for 5-6 days and obtained blastocysts were vitrified. RESULTS Use of the CAPA-IVM system led to a higher meiotic maturation rate in ovarian tissue oocytes (OTO) compared to standard IVM (56 vs 35%, p=0.0045) and had a tendency to result in lower degeneration after IVM. Only the CAPA-IVM method supported blastocyst formation. CONCLUSIONS The biphasic in vitro maturation system improved the competence of OTO in comparison to the standard IVM method. The study suggests that fertility preservation programs could become more efficient using IVM after capacitation culture.

Abstract
We report a case of ultrasound-guided ex vivo oocyte retrieval for fertility preservation in a woman with bilateral borderline ovarian tumor, for whom conventional transvaginal oocyte retrieval was deemed unsafe because of the increased risk of malignant cell spillage. Ovarian stimulation with gonadotropins was performed. Surgery was scheduled according to the ovarian response to exogenous gonadotropic stimulation; oophorectomized specimens were obtained by laparoscopy, and oocyte retrieval was performed ∼ 37 hours after the ovulatory trigger. The sum of 20 ovarian follicles were aspirated, and 16 oocytes were obtained. We performed vitrification of 12 metaphase II oocytes and 3 oocytes matured in vitro. Our result emphasizes the viability of ex vivo mature oocyte retrieval after controlled ovarian stimulation for those with high risk of malignant dissemination by conventional approach.

Abstract
Borderline ovarian tumors (BOTs) represent around 15% of all epithelial ovarian cancer. Around one third of those patients is under 40 and has not completed childbearing when the tumor is diagnosed. Cancer survivors are more and more concerned about their future fertility since a large proportion of those with BOTs are young. Whatever the tumor stage, information regarding future fertility after treatment and fertility preservation (FP) options must be delivered to all patients before treatment. A multidisciplinary team will discuss and propose personalized treatment and FP strategies. Nowadays, the FP options offered to patients with BOT are the followings: i) minimal invasive conservative surgery, ii) oocyte cryopreservation after controlled ovarian stimulation (COS) or in vitro maturation (IVM) and iii) ovarian tissue cryopreservation. Generally, the most common strategy to preserve future fertility is represented by minimal invasive conservative surgery. However, with the remarkable success and evolution of assisted reproductive technologies (ART) - notably progress and efficiency in COS and oocyte vitrification - have led to offer another potential approach for FP consisting in oocyte cryopreservation. Several COS protocols, such as random start or dual stimulation associating tamoxifen or aromatase inhibitors with gonadotropins provide similar results when compared to standard protocols while providing safety by minimizing the risk of high estrogen exposure. When COS is contraindicated, oocyte cryopreservation can still be possible throw IVM. Even though, oocyte competence after IVM is lower than that obtained after COS. A less used approach is cryopreservation of ovarian tissue, consisting in freezing ovarian cortex fragments for a future thawing and graft. Some concerns and limitations regard the ovarian cortex graft and the risk of reintroducing malignant cells once performed. Nonetheless, the latter it is the only option in prepubertal patients.

Abstract
AIM Epithelial ovarian cancer (EOC) can be a devastating diagnosis in women of reproductive age who desire future fertility. However, in early-stage disease, fertility-sparing surgery (FSS) can be considered in appropriately selected patients. METHODS This is a narrative descriptive review of the recent literature on FSS for EOC from oncologic, reproductive and endocrinologic perspectives. RESULTS The recurrence rate following FSS performed for stage I EOC in published retrospective studies collectively is 13% but ranges from 5 to 29%, while mortality ranges from 0 to 18%. Five-year disease-free survival following FSS is over 90% but decreases with higher stage and grade. Recurrences following FSS are more likely to be localized with a more favorable prognosis compared to recurrences following radical surgery. Adjuvant chemotherapy is recommended in women with high-risk disease, and strategies to minimize gonadotoxicity during chemotherapy such as gonadotropin-releasing hormone (GnRH) agonists may be considered. Oocyte, embryo and/or ovarian cryopreservation can also be offered to patients desiring future biologic children. Reproductive outcomes following FSS, including pregnancy and miscarriage rates, resemble those of the general population, with a chance of successful pregnancy of nearly 80%. CONCLUSION In retrospective data, FSS appears to be oncologically safe in stage IA and IC grade 1-2 non-clear cell EOC. In patients with grade 3 tumors or clear cell histology, treatment can be individualized, weighing a slightly higher risk of recurrence with fertility goals. A multidisciplinary approach with oncology and reproductive endocrinology may be of utility to help these patients achieve their fertility goals.

Abstract
With the increased rate of stable remission after gonadotoxic cancer treatment, new methods of fertility preservation are required in order to provide the best possible care for oncological patients. Here, we report an original case of euploid blastocyst cryopreservation after in vitro maturation of ovarian tissue oocytes (OTO IVM). Thirty-three oocytes were obtained from the ovarian tissue after ovariectomy in the breast cancer patient. Six out of 12 matured oocytes fertilized successfully and 3 blastocysts were formed. Genetic investigation for mutations associated with this type of malignancy found that the patient is not a carrier. Preimplantation genetic testing was performed only for aneuploidies and found all 3 blastocysts to be euploid and suitable for embryo transfer. Our study showed that the ovarian tissue oocytes matured in vitro have the potential for euploid blastocyst formation after ICSI which could be screened for aneuploidies and inherited mutations and then be vitrified in order to provide the best fertility preservation strategy for women with cancer.

Improving the maturation rate of human oocytes collected ex vivo during the cryopreservation of ovarian tissue. J Assist Reprod Genet 2020; 37:891-904. [PMID: 32096110 DOI: 10.1007/s10815-020-01724-7] [Citation(s) in RCA: 36] [Impact Index Per Article: 9.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/03/2019] [Accepted: 02/17/2020] [Indexed: 01/25/2023] Open
Abstract
PURPOSE The aim of the present study was to improve the in vitro maturation (IVM) procedure using oocytes from surplus ovarian tissue after fertility preservation. METHODS Twenty-five patients aged 17-37 years were included in the study. Maturation was compared between oocytes collected in HEPES-buffered medium or saline, and we determined whether transport on ice prior to oocyte collection affected maturation. Two different IVM media were used that were supplemented with and without recombinant human midkine. Mature oocytes were assessed for aneuploidy using next-generation sequencing (NGS). RESULTS On average, 36 immature oocytes were collected from each patient (range 7-90, N = 895). Oocytes recovered from HEPES-buffered medium matured at a higher rate than oocytes recovered from saline (36% vs 26%, p < 0.01). Ovarian transportation on ice prior to the procedure negatively affected maturation compared with non-transported samples (42% vs 27%, p < 0.01). The addition of midkine improved maturation rate (34% vs 27%, p < 0.05). On average, 11 MII oocytes were obtained per patient (range 1-30). NGS of 53 MII oocytes and their first polar bodies indicated that 64% were euploid. CONCLUSIONS The study demonstrated unexpectedly high number of immature oocytes collected from surplus ovarian tissue without any stimulation. The overall MII rate was one in three, resulting in a total number of MII oocytes that was similar to the number obtained after ovarian stimulation. If these MII oocytes prove suitable for IVF, they will provide a substantial improvement in fertility preservation for patients and advance IVM as an interesting platform for further improvements in assisted reproduction.

Abstract
We report a unique case of a rare utilization of IVM. This case shows the successful retrieval of immature oocytes followed by in vitro maturation (IVM) for fertility preservation in a patient undergoing chronic progestin contraception. A 24-year-old patient with anaplastic astrocytoma requiring chemotherapy with temozolomide for 12 cycles as soon as possible with wish for fertility preservation while using a long acting etonogestrel birth control implant presented in our unit for fertility preservation in May 2017. The currently used implant should be preserved for further contraception. As the ovaries presented with a high, pco-like, antral follicle count, IVM was offered; the patient agreed. A transvaginal follicular puncture in general anesthesia without any hormonal intervention and IVM of gained oocytes was performed. As the patient actually had no spouse, she decided to freeze unfertilized metaphase II stage oocytes (MII). Thirteen oocytes were obtained, eight of them could be matured and cryopreserved. IVM could be a possibility for fertility preservation in patients with polycystic ovaries when no time is available for stimulation for conventional in vitro fertilization. Even use of continuous progestin application for contraception is no obstacle.

Abstract
RESEARCH QUESTION Is overnight transportation of ovarian tissue before cryopreservation in a centralized cryobank from the FertiPROTEKT network feasible? DESIGN Data from 1810 women with cryopreserved ovarian tissue after overnight transportation from December 2000 to December 2017 were analysed with a focus on transportation, tissue activity parameters and pregnancy, and delivery rates after transplantation. RESULTS A total of 92.4% of tissue samples arrived at ideal temperatures of 2-8°C, 0.4% were transported at temperatures lower than ideal and 6.4% were transported at temperatures that were too high, generally due to mishandling of the inlayed cool packs of the transportation boxes. In 62 women, 78 tissue transplantations were carried out. A subgroup of 30 women who underwent a single orthotopic transplantation with fulfilled criteria of a complete follow-up after transplantation until the end of study, a premature ovarian insufficiency after gonadotoxic therapy as well as the absence of pelvic radiation, was further analysed. In this group, transplantations into a peritoneal pocket accounted for 90%. Transplants were still active at 1 year and above after transplantation in 93.3%. Pregnancy and delivery rates were 46.7% and 43.3%, respectively, with one ongoing pregnancy at the end of the study. CONCLUSIONS Overnight transportation for central cryobanking is a feasible concept that results in high reproducible success rates through standardized professional tissue freezing and storage.

BIOMED RESEARCH INTERNATIONAL 2018; 2018:6465903.

Abstract
Progress in recent years in the efficacy of oncologic treatment and early diagnosis of cancer has determined an increase in life expectance in cancer patients. About 10% of all cancer cases affect women younger than 45 years; therefore nowadays approximately 5-6% of the population in childbearing age consists in cancer survivors. A crucial issue is the high risk of premature ovarian insufficiency due to possible gonadotoxic effects of oncologic treatments. Considering combined chemotherapy, radiation therapy, and bone marrow transplantation, this risk can reach 92-100%, depending on the age and ovarian reserve of the patient, as well as the schedule and type of therapy. International guidelines recommend addressing all the patients diagnosed with a neoplasia treatable with potentially gonadotoxic therapies to fertility preservation. Moreover, fertility preservation also seems to reserve fascinating implications for women who want to delay childbearing for social reasons or women affected with endometriosis, who could receive unexpected opportunities. At present, the most widespread techniques to preserve fertility in adult women are embryo or oocyte cryopreservation, depending on the presence of a partner or according to legislative issues, but these procedures require time for ovarian stimulation. In prepubertal patients or when there is no possibility of delaying chemotherapy, ovarian tissue cryopreservation and subsequent transplantation represent the main strategy.

Abstract
Aim In recent years, the importance of fertility preservation (FP) has increased. In vitro maturation (IVM), an important technique in FP, has started to be used in the clinic, but controversies persist regarding this technique. Here, a survey of IVM for FP is provided. Methods Based on a literature review, the applications of FP, methods of FP, IVM of oocytes that had been collected in vivo and ex vivo, maturation of oocytes after IVM for FP, cryopreservation of oocytes for FP, explanation of the procedures to patients, and recent research on FP using IVM were investigated. Results Although IVM for FP remains controversial, the application of FP is expected to expand. Depending on the age and disease status of the patient, various methods of oocyte collection and ovarian stimulation, as well as various needle types and aspiration pressures, have been reported. The maturation rate of IVM in FP ranges widely and requires optimization in the future. In regard to cryopreservation for matured oocytes, the vitrification method is currently recommended. Conclusion Regarding FP for patients with cancer, the treatment of cancer is prioritized; thus, the time and use of medicines are often constrained. As several key points regarding IVM remain unclear, well‐designed and specific counseling for patients is necessary.

Abstract
On average, over 25000 women are diagnosed with breast cancer under the age of 45 annually in the United States. Because an increasing number of young women delay childbearing to later life for various reasons, a growing population of women experience breast cancer before completing childbearing. In this context, preservation of fertility potential of breast cancer survivors has become an essential concept in modern cancer care. In this review, we will outline the currently available fertility preservation options for women with breast cancer of reproductive age, discuss the controversy behind hormonal suppression for gonadal protection against chemotherapy and highlight the importance of timely referral by cancer care providers.

Abstract
PURPOSE The purpose of this study was to summarize the latest advances and successes in the field of ovarian tissue cryopreservation while identifying gaps in current knowledge that suggest opportunities for future research. METHODS A systematic review was performed according to PRISMA guidelines for all relevant full-text articles in PubMed published in English that reviewed or studied historical or current advancements in ovarian tissue cryopreservation and auto-transplantation techniques. RESULTS Ovarian tissue auto-transplantation in post-pubertal women is capable of restoring fertility with over 80 live births currently reported with a corresponding pregnancy rate of 23 to 37%. The recently reported successes of live births from transplants, both in orthotopic and heterotopic locations, as well as the emerging methods of in vitro maturation (IVM), in vitro culture of primordial follicles, and possibility of in vitro activation (IVA) suggest new fertility options for many women and girls. Vitrification, as an ovarian tissue cryopreservation technique, has also demonstrated successful live births and may be a more cost-effective method to freezing with less tissue injury. Further, transplantation via the artificial ovary with an extracellular tissue matrix (ECTM) scaffolding as well as the effects of sphingosine-1-phosphate (SIP) and fibrin modified with heparin-binding peptide (HBP), heparin, and a vascular endothelial growth factor (VEGF) have demonstrated important advancements in fertility preservation. As a fertility preservation method, ovarian tissue cryopreservation and auto-transplantation are currently considered experimental, but future research may pave the way for these modalities to become a standard of care for women facing the prospect of sterility from ovarian damage.
