Fertility-sparing surgery for patients with stage IC2 or IC3 epithelial ovarian carcinoma: any evidence of safety?

OBJECTIVE: Investigate the overall survival of patients with stage IC2/IC3 epithelial ovarian carcinoma undergoing fertility-sparing surgery. METHODS: Patients aged <45 years diagnosed between January 2004 and December 2015 with epithelial ovarian carcinoma, who underwent surgical staging and had tumor involving the ovarian surface (IC2), malignant ascites or positive cytology (IC3), were identified in the National Cancer Database. The fertility-sparing surgery group included patients who had preservation of the uterus and the contralateral ovary while the radical surgery group included patients who had hysterectomy with bilateral salpingo-oophorectomy. Overall survival was evaluated following generation of Kaplan-Meier curves while a Cox model was constructed to control for tumor grade and performance of lymphadenectomy. A systematic review of the literature was performed and cumulative relapse rate among patients with IC2/IC3 disease who underwent fertility-sparing surgery was calculated. RESULTS: A total of 235 cases were identified; 105 (44.7%) patients underwent fertility-sparing surgery. There was no difference in overall survival between the fertility-sparing and radical surgery groups (p=0.37; 5- year overall survival rates 90.2% and 85%, respectively). After controlling for tumor grade and performance of lymphadenectomy, fertility-sparing surgery was not associated with worse overall survival (HR 1.22, 95% CI 0.56, 2.62). A systematic review identified 151 patients with stage IC2/IC3 disease who underwent fertility-sparing surgery. Cumulative relapse rate was 19.3% (n=29) while 12 (6.7%) deaths were reported. Median time to recurrence was 19 (range 1-128.5) months. Tumor recurrence involved the ovary exclusively in 42% (11/26) of patients, while 15% (4/26) had a lymph node, 35% (9/26) a pelvic/abdominal, and 8% (2/26) a distant tumor relapse. CONCLUSIONS: In a large cohort of patients with stage IC2/IC3 epithelial ovarian carcinoma, fertility-sparing surgery was not associated with worse overall survival. However, based on a literature review, relapse rate is approximately 20%.

Inconsistencies in fertility preservation for young people with cancer in the UK.

OBJECTIVE: To assess the utilisation of and funding structure for fertility preservation for children diagnosed with cancer in the UK. DESIGN: Survey of paediatric oncologists/haematologists. Questionnaires were sent electronically with reminder notifications to non-responders. SETTING: UK Paediatric Oncology Principal Treatment Centres (PTCs). PARTICIPANTS: Paediatric oncologists/haematologists with an interest in the effects of treatment on fertility representing the 20 PTCs across the UK. MAIN OUTCOME MEASURES: Referral practices, sources and length of funding for storage of gametes or gonadal tissue for children diagnosed with cancer in the preceding 12 months. RESULTS: Responses were received from 18 PTCs (90%) with responses to 98.3% of questions. All centres had referred patients for fertility preservation: ovarian tissue collection/storage 100% (n=18 centres), sperm banking 100% (n=17; one centre was excluded due to the age range of their patients), testicular tissue storage 83% (n=15), mature oocyte collection 35% (n=6; one centre was excluded due to the age range of their patients). All centres with knowledge of their funding source reported sperm cryopreservation was NHS funded. Only 60% (n=9) centres reported the same for mature oocyte storage. Of the centres aware of their funding source, half reported that ovarian and testicular tissue storage was funded by charitable sources; this increased in England compared with the rest of the UK. CONCLUSIONS: Inequality exists in provision of fertility preservation for children with cancer across the UK. There is lack of formalised government funding to support international guidelines, with resultant geographical variation in care. Centralised funding of fertility preservation for children and young adults is needed alongside establishment of a national advisory panel to support all PTCs.

Clinical outcomes and utilization from over a decade of planned oocyte cryopreservation.

RESEARCH QUESTION: What is the clinical experience of patients who have undergone planned oocyte cryopreservation and oocyte thawing and warming? DESIGN: Retrospective observational cohort study. All women who completed planned oocyte cryopreservation at a single large university-affiliated fertility centre between June 2006 and October 2020 were identified, including the subset who returned to use their oocytes. Patients who underwent oocyte cryopreservation for medical reasons were excluded. Baseline demographics, oocyte cryopreservation and thawing-warming cycle parameters, and clinical outcomes, were extracted from the electronic medical record. The primary outcome was cumulative live birth rate (LBR), and secondary outcomes were cumulative clinical pregnancy rate (CPR), and CPR and LBR per transfer. Results were stratified by age at time of cryopreservation (<38 and ≥38 years). RESULTS: Of 921 patients who underwent planned oocyte cryopreservation, 68 (7.4%) returned to use their oocytes. Forty-six patients (67.6%) completed at least one embryo transfer. The CPR per transfer was 47.5% and LBR was 39.3%. The cumulative LBR per patient who initiated thawing-warming was 32.4%. Cycle outcomes were not significantly different in patients aged younger than 38 years and those aged 38 years or over. No patient aged 40 years or older (n = 6) was successful with their cryopreserved oocytes. Ten patients (14.7%) who were unsuccessful with their cryopreserved oocytes achieved a live birth using donor oocytes, with most (7/10) of these patients aged 38 years and older. CONCLUSION: Only a small percentage of patients returned to use their oocytes, and 32% of those were able to achieve a live birth.

Do stage and grade of malignancy impact fertility preservation in breast cancer patients?

INTRODUCTION: The impact of cancer on basal fertility and ovarian response to stimulation has not yet been clarified. Evidence on this topic is scarce and conflicting. Aim of this study was to assess the impact of breast cancer stage and grade on the number of retrieved mature oocytes during controlled ovarian stimulation for fertility preservation. METHODS: Retrospective cohort study evaluating data on 101 stimulation cycles of women with breast cancer undergoing oocyte cryopreservation categorized according to breast cancer stage (low-stage: I; high-stage:II-III) and grade (low-grade: G1-2; high-grade: G3) using the American Joint Committee on Cancer staging system (VIII edition). RESULTS: High-stage disease was not associated with worse oocyte retrieval outcomes (median 7 vs 7, p = 0.75). High-grade disease patients showed a significantly lower antral follicle count (AFC) compared to low-grade disease patients (10 vs 13, p = 0.03), and required higher doses of FSH (2612 IU vs 2250 IU; p = 0.03) during stimulation. Median number of vitrified oocytes was 6 in low-grade disease patients and 7 in high-grade disease patients (p = 0.35). CONCLUSIONS: Stage and grade of breast cancer do not impact the number of retrieved mature oocytes. However, higher grade of breast cancer is associated with lower AFC at baseline and need for higher doses of gonadotropin during ovarian stimulation.

Fertility preservation and PGT-M in women with familial adenomatous polyposis-associated desmoid tumours.

RESEARCH QUESTION: Is ovarian stimulation and pregnancy in women with familial adenomatous polyposis (FAP)-associated desmoid tumours safe? DESIGN: The study included women with FAP-associated desmoid tumours who underwent fertility treatments at the authors' tertiary medical centre between the years 2011 and 2021. Data were collected from the fertility unit's charts and from the oncological registries. The main outcome measures were the number of vitrified oocytes and embryos, and the number of live births in preimplantation genetic testing for monogenic/single gene defects (PGT-M) cycles. RESULTS: Overall, 17 women were identified suitable for this study. A total of 117 mature oocytes were vitrified for fertility preservation and 106 embryos were submitted to PGT-M. One patient returned to claim her cryopreserved oocytes, and five patients who underwent PGT-M embryo transfer reported three live births. A statistically significant decrease in selected fertility cycle parameters was observed in one woman who co-administered sorafenib (a multikinase inhibitor) during her first cycles of treatment, as the mean number of oocytes before and after was 2.7 (±1.3) versus 13.2 (±3.3) (P = 0.02), the mean number of metaphase II oocytes was 2.2 (±2.1) versus 7.7 (±2.6) (P = 0.007), and the mean number of two-pronuclei oocytes was 0.5 (±1.1) versus 3.5 (±1.7) (P = 0.09). Three patients had a median desmoid tumour growth on magnetic resonance imaging of 6.2 (2.9-7.2) cm when compared with prior ovarian stimulation imaging. CONCLUSIONS: Ovarian stimulation for women with desmoid tumours was characterized in some patients with an acceleration in tumour growth, regardless of the use of aromatase inhibitors. The use of sorafenib should be carefully considered during the course of fertility treatment.

Educational needs of fertility healthcare professionals using ART: a multi-country mixed-methods study.

RESEARCH QUESTION: What are the most pressing educational needs of fertility healthcare professionals using assisted reproductive technologies (ART)? DESIGN: This mixed-methods study combined qualitative interviews with quantitative surveys. Participants included physicians and nurses specialized in reproductive endocrinology or in obstetrics/gynaecology, and laboratory specialists, with a minimum of 3 years of experience, practising in Australia, Brazil, Canada, China, France, Germany, India, Italy, Japan, Mexico, Spain or the UK. Maximum variation purposive sampling was used to ensure a mix of experience and settings. Interviews were transcribed and coded through thematic analysis. Quantitative data were analysed using frequency tables, cross-tabulations and chi-squared tests to compare results by reimbursement context. RESULTS: A total of 535 participants were included (273 physicians, 145 nurses and 117 laboratory specialists). Knowledge gaps, skills gaps and attitude issues were identified in relation to: (i) ovarian stimulation (e.g. knowledge of treatments and instruction protocols for ovarian stimulation), (ii) embryo culture and cryopreservation/vitrification (e.g. diverging opinions on embryo freezing, (iii) embryo assessment (e.g. performing genetic testing), (iv) support of luteal phase and optimizing pregnancy outcomes (e.g. knowledge of assessment methods for endometrial receptivity), and (v) communication with patients (e.g. reluctance to address emotional distress). CONCLUSIONS: This descriptive, exploratory study corroborates previously reported gaps in fertility care and identifies potential causes of these gaps. Findings provide evidence to inform educational programmes for healthcare professionals who use ART in their practice and calls for the development of case-based education and interprofessional training programmes to improve care for patients with fertility issues.

Fertility preservation and sperm donation in transgender individuals: The current situation within the French CECOS network.

BACKGROUND: Many studies reported that reproductive desire could be high among transgender individuals. In France, fertility preservation and sperm donation were very little proposed to transgender individuals until recently, mainly because the Bioethics Law allows the use of assisted reproductive technologies only in infertile couples and prohibits surrogacy. OBJECTIVES: To evaluate the distribution of care on the French territory concerning fertility preservation and sperm donation in transgender individuals. MATERIALS AND METHODS: A multicentric national survey was carried out between January 2019 and October 2020 in 28 assisted reproductive technology centres of the French CECOS (Centres d'Etudes et de Conservation des Oeufs et du Sperme) network. Each centre was questioned to find out how many transgender individuals came, were informed and cared for fertility preservation and sperm donation. RESULTS: Concerning fertility preservation, 71.4% of centres received transgender individuals and performed gamete cryopreservation; 581 transgender individuals consulted for fertility preservation. Transgender women were more likely to desire (p < 0.0001) and achieve (p < 0.0001) fertility preservation than transgender men. Concerning sperm donation in couples including a transgender man, 68% of centres offer the complete course from the first consultation to the completion of the assisted reproductive technology cycles; 122 offsprings have been conceived with sperm donation in couples including a transgender man since 1999. DISCUSSION: Our results showed that even if all centres do not propose fertility preservation or sperm donation in transgender individuals, these assisted reproductive technologies are present throughout the French territory. The major point is that both fertility preservation and sperm donation in transgender individuals have grown significantly and that the care of these patients is improving year after year. CONCLUSION: In France, most of CECOS centres can take care of transgender individuals for fertility preservation and sperm donation. The French Bioethics Law allows these latter, and transgender individuals can benefit from a financial support of the national health care insurance for fertility preservation and sperm donation.

Oocyte accumulation for fertility preservation in women with benign ovarian tumours with a history of previous surgery, multiple or large cysts.

RESEARCH QUESTION: What are ovarian stimulation cycle outcomes and acceptance rates of an oocyte accumulation programme in young women with benign ovarian tumour (BOT)? DESIGN: Retrospective cohort study conducted at the Academic Assisted Reproductive Technology and Fertility Preservation Centre, Lille University Hospital, between January 2016 and December 2019. The number of metaphase II oocytes per cycle and per patient after accumulation were evaluated. Two groups were identified for the analysis: endometrioma ('endometrioma') and dermoid, mucinous or serous cyst ('other cysts'). RESULTS: A total of 113 fertility-preservation cycles were analysed in 70 women aged 27.9 ± 4.8 years. Almost all women had undergone previous ovarian surgery before fertility preservation (89%). Mean anti-Müllerian hormone levels before ovarian stimulation was 12.5 ± 8.7 pmol/l. A total of 6.4 ± 3.4 oocytes were retrieved, and 4.3 ± 3.4 metaphase II (MII) oocytes were vitrified per cycle. All agreed to the oocyte accumulation programme and all underwent at least one cycle. To date, 36 (51%) patients achieved two or three fertility- preservation cycles. After accumulation, 7.0 ± 5.23 MII oocytes were vitrified per patient. No difference was found in ovarian response and oocyte cohort between the 'endometrioma' and 'other cysts' groups. Questionnaires completed after oocyte retrieval revealed abdominal bloating and pelvic pain in most patients, with no difference according to the type of cyst. No serious adverse events occurred. CONCLUSIONS: Oocyte accumulation should be systematically offered to young women with BOT irrespective of histological type, as it seems to be well-tolerated. Long-term follow-up is needed to assess the efficiency of oocyte accumulation to optimize the chances of subsequent pregnancies.

IVF impact on the risk of recurrence of endometrial adenocarcinoma after fertility-sparing management.

RESEARCH QUESTION: Do IVF treatments after conservative management of endometrial atypical hyperplasia or grade 1 endometrial adenocarcinoma (AH/EC) increase the risk of disease recurrence? DESIGN: This is a prospective cohort study from a national registry from January 2008 to July 2019. Sixty patients had an AH/EC and received progestin treatment using chlormadinone acetate for at least 3 months. After remission, 31 patients underwent IVF and 29 did not. The primary outcome was the recurrence rate at 24 months according to the use of IVF. The secondary outcome was the identification of risk factors for recurrence. RESULTS: The probability of 2-year recurrence was 37.7% (SD 10.41%) in the IVF group and 55.7% (SD 14.02%) in the no IVF group (P = 0.13). Obesity, nulliparity, polycystic ovary syndrome, age and tumoural characteristics were not associated with recurrence. Pregnancy was a protective factor for recurrence, with 2-year recurrence probabilities of 20.5% and 62.0% in the pregnancy and no pregnancy groups, respectively (P = 0.002, 95% CI 0.06-0.61). In contrast, the number of cycles, maximum serum oestradiol concentration during ovarian stimulation, ovarian stimulation protocol, total dose of gonadotrophin administered and thickness of the endometrium showed no significant differences in terms of the risk of recurrence in the IVF subgroup. CONCLUSION: IVF treatment after fertility-sparing management of AH/EC does not increase the risk of recurrence. Therefore, it is an acceptable strategy to decrease the time to pregnancy. Overall, the recurrence rate is high enough to justify close monitoring once remission occurs.

The evolving landscape of donor egg treatment: success, women's choice, and anonymity.

PURPOSE: To analyze donor oocyte (DE) data across 6 years for oocyte usage efficiency, trends, and whether changes impacted outcomes. METHODS: From 2014 to 2019, 323 DE embryo transfers were completed in 200 recipients using oocytes derived of 163 donors. We assessed data for oocytes being freshly retrieved (FRESH-EGG) vs. purchased frozen (FROZEN-EGG); embryos transferred fresh (FRESH-ET) vs. frozen (FROZEN-ET); cycles SHARED (two recipients) vs. SOLE (one recipient); single (SET) vs. double (DET) embryo transfers and usage of PGT-A. Primary outcome was ongoing pregnancy plus live birth (OP/LB) rate. RESULTS: A total of 229 FRESH-EGG (70%) and 94 FROZEN-EGG (30%) cycles were completed. Overall, the use of FRESH-EGG yielded a higher OP/LB compared to FROZEN-EGG (49% vs. 30%, p = 0.001); within the FRESH-EGG group, OP/LB was similar when comparing FRESH-ET vs. FROZEN-ET (58% vs. 45%, p = 0.07). Within the FRESH-ET group, those using FRESH-EGG had a higher OP/LB than those using FROZEN-EGG (58% vs. 27%, p < 0.001). SHARED vs. SOLE cycles (p = 0.6), donor age (21-32 years; p = 0.4), and age of intended parents (maternal p = 0.3, paternal p = 0.2) did not significantly impact OP/LB. Notably, the use of PGT-A did not improve odds for an OP/LB (p = 0.7). CONCLUSION: The use of FRESH-EGG with FRESH-ET without PGT-A remains superior to newer DE treatment combinations. Specifically, the use of FROZEN-EGG and PGT-A did not improve outcomes. Although changing DE practices may enhance experience and affordability, patients and providers must appreciate that choices do not always favorably impact success. Additionally, newly available genetic-ancestry testing may pose longer-term ramifications mandating change in treatment and/or counseling.

Parenthood Rates and Use of Assisted Reproductive Techniques in Younger Hodgkin Lymphoma Survivors: A Danish Population-Based Study.

PURPOSE: The majority of young adults with Hodgkin lymphoma (HL) are cured, but chemotherapy-induced infertility can have profound psychosocial consequences. Providing data on parenthood rates and use of assisted reproductive techniques (ARTs) after contemporary HL treatment is important for patient counseling and survivorship care. MATERIALS AND METHODS: All Danish patients with HL diagnosed during 2000-2015 at the ages 18-40 years who achieved remission after first-line therapy were included and matched on age, sex, and parenthood status to five random persons from the general population. Parenthood rates were defined as the rate of first live birth per 1,000 person years, starting 9 months after HL diagnosis. Nationwide birth and patient registers were used to capture parenthood outcomes and ARTs use. RESULTS: A total of 793 HL survivors and 3,965 comparators were included (median follow-up 8.7 years). Similar parenthood rates were observed for male and female HL survivors when compared with matched comparators (56.2 v 57.1; P = .871 for males and 63.8 v 61.2; P = .672 for females). For male HL survivors, BEACOPP (bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisone) therapy was associated with lower parenthood rates as compared to the matched comparators (28.1 v 60.8; P = .020). Live birth after ARTs were more common for HL survivors than for comparators (males 21.6% v 6.3%; P < .001; females 13.6% v 5.5%; P = .001). There were no differences in gestational age, Apgar score, or newborn measurements between HL survivors and matched comparators. CONCLUSION: The parenthood rates for HL survivors who have not experienced relapse were generally similar to the general population. However, ARTs were used more often before the first live birth in HL survivors, which is relevant information when discussing possible long-term side effects and fertility-preserving treatment options.

Reproductive functions and fertility preservation in transgender women: a French case series.

RESEARCH QUESTION: The reproductive potential of transgender people may be impaired by gender-affirming hormone treatment (GAHT) and is obviously suppressed by gender-affirming surgery involving bilateral orchiectomy. The evolution of medical support for transgender people has made fertility preservation strategies possible. Fertility preservation in transgender women mainly relies on sperm cryopreservation. There are few studies on this subject, and the sample sizes are small, and so it difficult to know whether fertility preservation procedures are feasible and effective in trans women. DESIGN: This retrospective study reports the management of fertility preservation in transgender women referred to the study centre for sperm cryopreservation, and the semen parameters of trans women were compared with those of sperm donors. RESULTS: Ninety-six per cent of transgender women who had not started treatment benefitted from sperm cryopreservation, compared with 80% of those who attempted a therapeutic window and 50% of those receiving hormonal treatment at the time of sperm collection. No major impairment of semen parameters was observed in transgender women who had not started GAHT compared with sperm donors. However, even though the frequency of oligozoospermia was no different, two transgender women presented azoospermia. Some transgender women who had started GAHT could benefit from sperm freezing. None of them were treated with gonadotrophin-releasing hormone (GnRH) analogues. CONCLUSIONS: Parenthood strategies for transgender people have long been ignored, but this is an important issue to consider, especially because medical treatments and surgeries may be undertaken in adolescents or very young adults. Fertility preservation should ideally be offered prior to initiation of GAHT.

Transplantation of cryopreserved ovarian tissue in a series of 285 women: a review of five leading European centers.

The feasibility of freezing and thawing ovarian tissue is nowadays widely documented. However, ovarian tissue transplantation (OTT) is happening at a much slower pace, and clinical experience is somewhat limited. In this review, five European centers present their collective experience of transplanting ovarian tissue in 285 women. The focus is on surgical techniques and OTT outcomes, reproductive outcomes, the impact of chemotherapy before ovarian tissue cryopreservation (OTC), the risk of relapse, and endocrine resumption and longevity of transplanted tissue. The risk of relapse due to reimplantation of ovarian tissue appears to be very low according to current data. Recovery of endocrine function is seen in almost all women undergoing transplantation of ovarian tissue, and about one in four gives birth to a healthy child. The efficacy of in vitro fertilization in these patients is not very high, however, and needs to be substantially improved. Radiation to the pelvis, especially with relatively high doses, appears to considerably decrease the likelihood of a successful pregnancy and may be contraindicated. Our results demonstrate that chemotherapy before OTC does not impair the chances of success, depending, of course, on the total dose and type of chemotherapy administered. At this early stage of development of OTT for restoration of fertility, the results are encouraging and demonstrate clear potential. However, the method is far from being fully developed and requires continued research efforts to optimize our approach.

Real-world anticancer medications for reproductive-age women with breast cancer by using a claims database in Japan.

Aim: To describe real-world breast cancer medications among reproductive-age women. Patients & methods: Using data from a Japanese claims database, anticancer prescriptions were classified into seven categories of amenorrhea risk based on fertility preservation guidelines. Results: We identified 2999 women with records of breast cancer and anticancer prescription from 2005 to 2018. The proportions of prescriptions were as follows: high, 4.1-12.9%; intermediate: 6.0-16.3%; low: 0.4-2.3%; very low/no: 0.3-12.2%; unknown: 33.9-45.5%; unlisted combination: 12.2-23.4%; and unlisted drug: 12.5-26.7%. The common drugs in the unknown category were trastuzumab (n = 1527), docetaxel (n = 1014), and paclitaxel (n = 995). For medications unlisted in the guidelines, various drugs and drug combinations were observed. Conclusion: Numerous anticancer drugs are currently being prescribed with insufficient evidence regarding amenorrhea risk.

Lay abstract The ability to have children for breast cancer patients is one of the key issues of cancer survivorship, especially because recent progress in anticancer treatments has enabled patients to achieve longer survival. The fertility preservation guidelines of the American Society of Clinical Oncology (2006) introduce some anticancer treatments that carry potential risks to future fertility. In this study, the anticancer prescriptions of 2999 patients with breast cancer aged between 15 and 49 years were examined. Results showed that several medications are prescribed despite the lack of information on the risk of infertility. This suggests that further research is required to fill the evidence gap, and that decision aid through adequate counseling should be undertaken.

Number needed to freeze: cumulative live birth rate after fertility preservation in women with endometriosis.

RESEARCH QUESTION: How does the number of oocytes used affect the cumulative live birth rate (CLBR) in endometriosis patients who had their oocytes vitrified for fertility preservation? DESIGN: Retrospective observational study including data from 485 women with endometriosis who underwent fertility preservation from January 2007 to July 2018. Survival curves and Kaplan-Meier plots were used to analyse the CLBR according to the number of vitrified oocytes used. Endometriosis curves were compared with plots developed using elective fertility preservation (EFP) patients as control group. Log-rank, Breslow and Tarone-Ware tests were used to compare the survival curves. RESULTS: The CLBR increased as the number of oocytes used per patient rose, reaching 89.5% (95% confidence interval [CI] 80.0-99.1%) using 22 oocytes. Higher outcomes were observed in young women (≤35 years old versus >35 years old). In the younger group, the CLBR was 95.4% (95% CI 87.2-103.6%) using approximately 20 oocytes versus 79.6% (95% CI 58.1-101.1%) in older women (log-rank [Mantel-Cox] P = 0.002). The mean age was higher in EFP patients (37.2 ± 4.9 versus 35.7 ± 3.7; P < 0.001). The outcome was better in the endometriosis group as compared with EFP: a CLBR of 89.5% (95% CI 80.0-99.1%) versus 59.9% (95% CI 51.4-68.6%) when 22 oocytes were used (log-rank [Mantel-Cox] P < 0.00001). CONCLUSION: The probability of live birth increases as the number of oocytes used increases in patients with endometriosis, but better outcomes were observed among young women. The information provided here may be of interest to both patients and treating physicians for counselling purposes.

Reduced response to controlled ovarian stimulation after radical trachelectomy: A pitfall of fertility-sparing surgery for cervical cancer.

OBJECTIVE: To clarify the decrease in response to controlled ovarian stimulation in patients who receive in vitro fertilization treatment after radical trachelectomy. METHODS: The outcomes of ovarian stimulation were retrospectively evaluated and compared between patients who have undergone radical trachelectomy and control patients who had male factor infertility or unexplained infertility. RESULTS: A total of 30 ovarian stimulation cycles in 14 radical trachelectomy patients and 54 cycles in 30 control patients were reviewed. The median age at ovarian stimulation was 34.8 years in the radical trachelectomy group and 36.5 years in the control group. Compared with the control group, the radical trachelectomy group had significantly lower mean estradiol concentration (1461.7 pg/ml, SD 775.0 vs. 1950.9 pg/ml, SD 1057.3, P = 0.029) during controlled ovarian stimulation cycle and smaller median number of retrieved oocytes (5, range 1-14 vs. 8, range 1-19, P = 0.007), despite the higher use of gonadotropin (3527.5 IU, SD 1313.4 vs. 2670.8 IU, SD 905.1, P = 0.001). CONCLUSION: The response to controlled ovarian stimulation decreased after radical trachelectomy.

Variables affecting long-term usage rate of sperm samples cryopreserved for fertility preservation in cancer patients.

BACKGROUND: Previous evidence highlighted that only a minority of men who banked their semen before cancer therapies subsequently used their frozen samples. This may question the economical validity of sperm cryopreservation programmes. However, in most contributions, the duration of follow-up was insufficient to draw robust information on the real rate of use. OBJECTIVES: To shed more light on the potential benefits of cryopreservation programmes. MATERIALS AND METHODS: Men who cryopreserved their semen in a public hospital for a diagnosis of cancer between 1986 and 2009 were retrospectively reviewed. The rate of use as well as the possible determinants was investigated. RESULTS: The median time of follow-up was 12 [IQR: 7-16] years. One hundred forty-four patients out of 1,524 (9.4%, 95%CI: 8.1%-11.0%) used their frozen samples of whom 64% were azoospermic. The rate of men achieving parenthood with frozen semen was 46%. Predictive factors of use were older age at the time of storage, lower sperm count at the time of storage and a diagnosis of testicular cancer. The impact of this latter factor was also supported by the lower frequency of azoospermia after cancer treatment in these patients. DISCUSSION: Cost-beneficial studies are warranted to assess and possibly improve the economical validity of sperm banking. CONCLUSION: The usage rate of frozen sperm in cancer patient is low, even extending the duration of follow-up.

Planned oocyte cryopreservation (Planned OC): systematic review and meta-analysis of cost-efficiency and patients' perspective.

BACKGROUND: Advances in vitrification techniques have enabled planned oocyte cryopreservation ('Planned OC'). OBJECTIVES: To explore the cost-efficiency and utilisation of planned OC, as well as patients' perspectives on the process. SEARCH STRATEGY: A systematic search in PubMed/MEDLINE, Embase, Cochrane Database and PsychINFO, for all relevant studies published between January 2007 and December 2019. SELECTION CRITERIA: The protocol followed PRISMA guidelines in PECO format, and was registered with PROSPERO. DATA COLLECTION AND ANALYSIS: Two independent reviewers evaluated all manuscripts for inclusion eligibility. Authors were contacted for missing data. Included studies were assessed for risk of bias and for heterogeneity. Weighted effects were measured and plotted. MAIN RESULTS: The search yielded 12 545 records, of which 43 were included. Planned OC is cost-efficient at 35, assuming 60% utilisation; and at 37 assuming utilising donor sperm when necessary. At 38 it is cost-efficient to defer planned OC in favour of undergoing 2 IVF cycles. Currently, utilisation of banked-oocytes within 22-58 months, is up to 15%. Nine percent of warmed banked oocytes result in life births. Online resources and treating physicians are equally important sources of information regarding planned OC. Most patients think planned OC is ideal before age 35 and are not fully aware of what the process entails and tend to overestimate the success rates. The main barrier to wider endorsement of planned OC is being wary of potential health implications or of limited success. CONCLUSION: Planned OC is an adequate method for preserving fertility. However, knowledge gaps result in under-utilisation leading to reduced cost-efficiency. TWEETABLE ABSTRACT: Identifying facilitators and barriers for wider adoption of banking oocytes can enhance the cost-efficiency of this modality.

Parenthood desire, childbearing plans and oocyte utilization among women who previously underwent planned oocyte cryopreservation.

RESEARCH QUESTION: To examine the motivations, life circumstances and parenthood aspirations of a cohort of women who underwent planned oocyte cryopreservation (POC) at a Canadian academic IVF centre. DESIGN: A single-site, cross-sectional, anonymous quantitative study using a study-specific questionnaire administrated via SurveyMonkey®. Of the 224 women who completed at least one POC cycle between 2012 and 2018, 198 were reached by email and invited to participate. RESULTS: Of the 98 (49.5%) questionnaires returned, 86 were fully completed and were analysed. Mean age at first POC cycle was 35.7 ± 2.4 (range 27-43) and at survey was 37.7 ± 2.5 years. At POC, 77% were single and 97.7% childless. At survey, 96% had not attempted to use their cryopreserved oocytes, yet 26 (30%) had tried natural conception or fertility treatments. Of these, three conceived naturally and two by assisted reproduction. Eighty-five per cent expressed a strong motherhood desire and 67.1% indicated that usage of their cryopreserved oocytes was mostly contingent on relationship status. Many expressed a desire for shared genetic parenthood within a committed relationship. Forty-seven per cent did not want to carry a pregnancy beyond the age of 46. CONCLUSION: The findings of this study confirm the central role of age and relationship status in influencing women's POC decisions and oocyte utilization plans. The late age at POC could be explained by women using it toward the end of their peak reproductive years to leverage their remaining chances of genetic motherhood. Surveying women at later points following POC would help to gain a more comprehensive picture of their oocyte utilization and disposition plans.

Uterine Artery Embolization Compared with High-intensity Focused Ultrasound Ablation for the Treatment of Symptomatic Uterine Myomas: A Systematic Review and Meta-analysis.

OBJECTIVE: This study aimed to compare the clinical effects of uterine artery embolization (UAE) with those of high-intensity focused ultrasound (HIFU) ablation for the treatment of symptomatic uterine myomas. DATA SOURCES: We searched PubMed, EMBASE, Web of Science, Cochrane Library, Google Scholar, and ClinicalTrials.gov for studies from January 2000 to August 2020. Related articles and relevant references of the included studies were also searched. METHODS OF STUDY SELECTION: Two researchers independently performed the data selection. We included comparative studies that compared the clinical outcomes of UAE with those of HIFU ablation in women with myomas. TABULATION, INTEGRATION, AND RESULTS: We assessed the study quality using the Cochrane Handbook for Systematic Reviews of Interventions for evaluating the risk of bias. Two independent researchers performed the article selection according to the screening criteria and rated the quality of evidence for each article. We calculated pooled mean difference with 95% confidence interval (CI) for continuous data and relative risk (RR) with 95% CI for dichotomous data. The systematic review registration number is CRD42020199630 on the International Prospective Register of Systematic Reviews. A total of 7 articles (5 trials), involving 4592 women with symptomatic uterine myomas, were included in the meta-analysis. Compared with the HIFU ablation group, the decrease in "uterine fibroid symptom" scores as well as the increase in quality-of-life scores at the time of follow-up were higher in the UAE group, with overall mean difference 19.54 (95% CI, 15.21-23.87; p <.001) and 15.72 (95% CI, 8.30-23.13; p <.001), respectively. The women in the UAE group had a significantly lower reintervention rate (RR 0.25; 95% CI, 0.15-0.42; p <.001). The women undergoing UAE had a significantly lower pregnancy rate than those undergoing HIFU ablation (RR 0.06; 95% CI, 0.01-0.45; p = .006). The difference in the incidence of adverse events between the 2 groups was not statistically significant (p = .53). CONCLUSION: Compared with HIFU ablation, UAE provided more significant alleviation of symptoms and improvement in quality of life, lower postoperative reintervention rate, and lower pregnancy rate for women with uterine myomas. However, we cannot conclude that HIFU ablation is more favorable for desired pregnancy than UAE because of the confounding factors.
