Yahyaei A, Moridi M, Ghaffari F. Controlled ovarian stimulation in cancer patients under 18 years old; a case series. J Ovarian Res 2024; 17:33. [PMID: 38317250 PMCID: PMC10840237 DOI: 10.1186/s13048-024-01352-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/11/2023] [Accepted: 01/13/2024] [Indexed: 02/07/2024] Open
Abstract
BACKGROUND Fertility preservation for adolescent pubescent girls is a concern of the healthcare system and parents. Oocyte cryopreservation is regarded as a standard medical intervention for patients with a minimum age of 18 years. Evidence suggests that mature oocyte cryopreservation is possible for adolescent pubescent girls, although, ovarian stimulation for these patients remains a challenge. CASES PRESENTATION This case series is the first report regarding ovarian stimulation with oocyte cryopreservation in younger than 18 years cancerous girls, who refer to ROYAN institute, Tehran, Iran, prior to the start of the treatment of cancer (November 2015 to February 2021). The oocyte cryopreservation was carried out in the 7 patients (five patients with Hodgkin lymphoma, one patient with Ewing sarcoma, and one patient with osteogenic tumor), the embryo cryopreservation in one patient with dysgerminoma, and the oocyte and embryo cryopreservation in one patient with germ cell tumor. No oocytes were retrieved after ovarian stimulation in the patient with medulloblastoma. For one of the patients with Hodgkin lymphoma, half of the tissues of one ovary were cryopreserved prior to ovarian stimulation. CONCLUSIONS Oocyte cryopreservation is a feasible option of fertility preservation in the adolescent's patients with cancer. However, only if reported acceptable fertilization rates, as well as the successful cases of live birth from oocyte cryopreservation at the ages under 18, this option of preserving fertility can be applied to this age range.

Abstract
PURPOSE OF REVIEW We reviewed the most recent developments including the safety and effectiveness data and success rates in individualized ovarian stimulation protocols for adult and postpubertal females with cancer. RECENT FINDINGS In women with breast cancer, aromatase inhibitor- and tamoxifen-supplemented stimulation protocols increase the margin of safety by limiting estrogen exposure. The outcomes of ovarian stimulation appear similar between cancer and noncancer populations, even with the recently developed random-start protocols, which allow initiation of ovarian stimulation anytime during the menstrual cycle. Based on lower anti-Mullerian hormone levels and primordial follicle density, carriers of BRCA pathogenic variants ( BRCApv ) have decreased ovarian reserve in comparison to women without those variants and may lose larger portion of their ovarian reserve post chemotherapy. Oocyte cryopreservation is also emerging as a suitable fertility preservation approach for selected postpubertal girls as young as 12 years of age. SUMMARY Individualized ovarian stimulation approaches combined with improvements in cryopreservation techniques increased the success and safety margin to preserve fertility with oocyte freezing. Women with BRCApv , on the other hand, may be at disadvantage as they have lower ovarian reserve and may lose larger portion of their ovarian reserve post chemotherapy compared to women who do not carry these variants.

Ovarian stimulation and oocyte cryopreservation in females and transgender males aged 18 years or less: a systematic review. Front Endocrinol (Lausanne) 2023; 14:1146476. [PMID: 37404308 PMCID: PMC10315913 DOI: 10.3389/fendo.2023.1146476] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/17/2023] [Accepted: 05/15/2023] [Indexed: 07/06/2023] Open
Abstract
Background Fertility preservation is an important healthcare focus in the paediatric and adolescent population when gonadotoxic treatments are required. Ovarian stimulation (OS) resulting in oocyte cryopreservation is a well-established fertility preservation option in the adult population. It's utility, however, is little known in young patients. The purpose of this review was to synthesise the available literature on OS in patients ≤18 years old, to identify gaps in current research and provide suggestions for future research directions. Methods Using PRISMA guidelines, a systematic review of the literature was performed for all relevant full-text articles published in English in Medline, Embase, the Cochrane Library and Google Scholar databases. The search strategy used a combination of subject headings and generic terms related to the study topic and population. Two reviewers independently screened studies for eligibility, extracted data and assessed the risk of bias. Characteristics of the studies, objectives and key findings were extracted and summarised in a narrative synthesis. Results Database search and manual review identified 922 studies, 899 were eliminated based on defined exclusion criteria. Twenty-three studies were included and comprised 468 participants aged ≤18 years who underwent OS (median 15.2, range 7-18 years old). Only three patients were premenarchal, and four patients were on treatment to suppress puberty. Patients had OS for a broad range of indications including oncology treatment, transgender care and Turner syndrome. A total of 488 cycles of OS were completed, with all but 18 of these cycles (96.3%) successfully resulting in cryopreserved mature oocytes (median 10 oocytes, range 0-35). Fifty-three cycles (9.8%) were cancelled. Complications were rare (<1%). One pregnancy was reported from a female who had OS aged 17 years old. Conclusion This systematic review demonstrates that OS and oocyte cryopreservation is achievable in young females however there are only a few cases in the literature describing OS in premenarcheal children or those who have suppressed puberty. There is little proof that OS can lead to pregnancy in adolescents, and no proof that this can be achieved in premenarchal girls. Therefore it should be regarded as an innovative procedure for adolescents and experimental for premenarcheal girls.

Controlled Ovarian Stimulation Initiated at Different Phases of the Menstrual Cycle for Fertility Preservation in Oncological Patients: a Retrospective Study. Reprod Sci 2023:10.1007/s43032-023-01175-2. [PMID: 36752986 DOI: 10.1007/s43032-023-01175-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/05/2022] [Accepted: 01/13/2023] [Indexed: 02/09/2023]
Abstract
The purpose of this study is to compare conventional start in early follicular phase (EFP) with late follicular phase (LFP) and luteal phase (LP) in controlled ovarian stimulation (COS) for fertility preservation (FP) to assess differences in clinical outcomes. Retrospective study of the first cycles of COS for FP in oncological patients between 2012 and 2020 in a tertiary hospital. Two-hundred forty-eight cycles were classified into 3 groups: 176 cycles in EFP, 8 cycles in LFP, and 52 cycles in LP. Comparing LFP to EFP, there were no differences in number of oocytes (10.0 [6.3-16.0] vs 12.0 [8.0-18.0]; p = 0.253) or number of metaphase II (MII) obtained (7.0 [2.3-13.3] vs 9.0 [6.0-13.0]; p = 0.229). Total number of days needed was higher in LFP (14.5 [12.5-16.0] vs 3.0 vs 10.0 [8.3-11.0 p = 0.000) but without significant differences in number of days of usage of gonadotropins (11.5 [8.3-12.8] vs 10.0 [8.3-11.0] p = 0.308). No differences were found between LP and EFP in number of oocytes (14.5 [9.0-20.0] p = 0.151) or MII (11.5 [7.0-16.0] p = 0.084). Number of days of gonadotropins (11.0 [10.0-12.0] p = 0.00) and total dosing (3000.0 [2475.0-3600.0] p = 0.013) were significantly higher in LP. FORT and FOI were similar in all groups. COS with a random start in fertility preservation has similar outcomes to EFP start. Therefore, we can initiate COS at any phase of the menstrual cycle with optimal results. However, LP may need more days of stimulation.

Abstract
PURPOSE The SART CORS database is an informative source of IVF clinic-specific linked data that provides cumulative live birth rates from medically assisted reproduction in the United States (US). These data are used to develop best practice guidelines, for research, quality assurance, and post-market surveillance of assisted reproductive technologies. Here, we sought to investigate the key areas of current research focus (higher-order categories), discover gaps or underserved areas of ART research, and examine the potential application and impact of newer ART adjuvants, future data collection, and analysis needs. METHODS We conducted a systematic review (PRISMA guidelines) to quantify unique output metrics of the SART CORS database. Included were SART member reporting clinics: full-length publications from 2004 to 2021 and conference abstracts from 2015 to 2021, the two key timepoints when the SART CORS database underwent transformative shifts in data collection. RESULTS We found 206 abstracts presented from 2015 to 2021, 189 full-length peer-reviewed publications since 2004, with 654 unique authors listed on these publications. A total of 19 publications have been highly impactful, garnering over 100 citations at the time of writing. Several higher-order categories, such as endometriosis and tubal infertility, have few publications. The conversion of conference abstracts to full-length papers ranged from 15 to 35% from 2015 to 2021. CONCLUSIONS A substantial body of literature has been generated by analyzing the SART CORS database. Full-length publications have increased year over year. Some topic areas, such as endometriosis and tubal infertility, may be underrepresented. Conversion of conference abstracts to full-length publications has been low, indicating that more organizational support may be needed to ensure that research is methodologically sound and researchers supported to reach full publication status.

Abstract
The objective of this study was to describe the opinions and attitudes toward planned oocyte cryopreservation (POC) among Black Obstetrician Gynecologists (BOG) and their experiences in counseling patients of color. A web-based, cross-sectional survey was distributed to BOGs. The survey consisted of questions pertaining to personal family building goals, fertility preservation, education and patient counseling experiences regarding POC. Of the 136 potential participants, the response rate was 50% (n = 68). Sixty-six percent of respondents felt the need to postpone childbearing due to medical training and 19% had already undergone POC or planned to in the future. A majority (70%) felt that all women planning to undergo medical training should consider POC, and a subgroup analysis showed this was more likely to be reported within BOG trainees (p < 0.01). Fifty-seven percent received education on POC and 25% felt "very comfortable" counseling patients on POC. Those age < 35 years were more likely to feel the need to postpone family building due to their medical training (p < 0.01). Generalist attendings who had not undergone POC were significantly more likely to report regret, compared to subspecialists (p < 0.03). Medical careers may have an unfavorable impact on family building, and our results highlight this effect in Black women. A better understanding of the mitigating factors is needed to develop culturally appropriate counseling and educational interventions for Black women and other women of color.

Abstract
Chemotherapy, pelvic radiotherapy and ovarian surgery have known gonadotoxic effects that can lead to endocrine dysfunction, cessation of ovarian endocrine activity and early depletion of the ovarian reserve, causing a risk for future fertility problems, even in children. Important determinants of this risk are the patient’s age and ovarian reserve, type of treatment and dose. When the risk of premature ovarian insufficiency is high, fertility preservation strategies must be offered to the patient. Furthermore, fertility preservation may sometimes be needed in conditions other than cancer, such as in non-malignant diseases or in patients seeking fertility preservation for personal reasons. Oocyte and/or embryo vitrification and ovarian tissue cryopreservation are the two methods currently endorsed by the American Society for Reproductive Medicine, yielding encouraging results in terms of pregnancy and live birth rates. The choice of one technique above the other depends mostly on the age and pubertal status of the patient, and personal and medical circumstances. This review focuses on the available fertility preservation techniques, their appropriateness according to patient age and their efficacy in terms of pregnancy and live birth rates.

Abstract
OBJECTIVE To characterize national outcomes of oocyte thaw (OT) cycles. DESIGN Retrospective descriptive study. SETTING All autologous OT cycles reported to the Society of Assisted Reproductive Technology Clinic Outcome Reporting System from 2012 to 2018. PATIENT(S) All women undergoing OT cycles in the United States. INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) Absolute numbers of oocyte cryopreservation (OC) and OT cycles over time. Among OT cycles, patient and cycle characteristics, the ratio of the total number of oocytes thawed to the number of live births by maternal age at the time of cryopreservation (ATOC), and outcomes including pregnancy, miscarriage, live birth, and good perinatal outcome (GPO) by age ATOC. RESULT(S) From 2012 to 2018, 54,675 OC and 6,413 OT cycles were performed; the absolute numbers increased from 2,719 to 13,824 and from 348 to 1,810, respectively. The ratio of the total number of oocytes thawed to the number of live births increased significantly with increasing age ATOC, from 41.4 (age <35 years) to 122.4 (age >41 years). Among OT cycles resulting in embryo transfer, the live birth rate decreased with increasing age ATOC from 42.8% (age <35 years) to 10.8% (age >42 years). The live birth rate was higher when calculated per transfer (42.8% in women aged <35 years ATOC) rather than per thaw cycle (31.5% in women aged <35 years ATOC) because of the number of patients with no transfer. Among 1,124 cycles resulting in pregnancy, the chance of a GPO was highest among women aged <35 years ATOC (65.8%) and decreased as age at ATOC increased. CONCLUSION(S) Among reported OT cycles, the rates of pregnancy and live birth decreased as age ATOC increased. The number of oocytes thawed to achieve one live birth increased significantly with increasing age ATOC. In addition, among the resulting pregnancies, the rate of GPO decreased as age ATOC increased.

Abstract
OBJECTIVE To describe the trends and characteristics of oocyte cryopreservation (OC) cycles stratified by self-reported race/ethnicity in the United States DESIGN: Retrospective cohort analysis using the Society for Assisted Reproductive Technology Clinical Outcome Reporting System SETTING: US fertility clinics PATIENTS: All patients undergoing OC from 2012 through 2016 INTERVENTIONS: None MAIN OUTCOME MEASURES: The OC cycle trends were analyzed on the basis of race/ethnicity: non-Hispanic white, non-Hispanic black, Asian/Pacific islander, Hispanic, and other (American Indian, Alaskan native, or mixed race). RESULTS Between 2012 and 2016, there was a total of 29,631 OC cycles; the total number of cycles increased yearly from 2,925 in 2012 to 8,828 in 2016. When compared with the demographics of the United States, OC was underused by some minority patient groups because majority of the cycles (66.5%) were performed in white patients. The total number of OC cycles increased annually among all the ethnic groups, most notably among Asian patients. The patients of all the ethnic backgrounds were most commonly under 35 years of age and underwent 1 OC cycle, except for Asian patients, who most frequently underwent OC between the ages of 35 and 37 years and were more likely to have undergone ≥2 cycles than patients of other minority groups. After adjustment for cofounders, there were no clinically significant differences in oocyte yield and the percentage of maturation across the racial/ethnic groups. CONCLUSIONS Nationally, OC cycles have been increasing in number, most often in patients under the age of 35 years, with similar proportions of patients of minority groups pursuing OC over time. The oocyte yield was comparable across the ethnic groups. Future research regarding subsequent thawing outcomes is warranted.

Abstract
PURPOSE The majority of data regarding oocyte cryopreservation (OC) outcomes focuses on healthy women. We compare trends, cycle characteristics, and outcomes between women freezing oocytes for fertility preservation due to cancer versus elective and other medical or fertility-related diagnoses. METHODS Retrospective cohort using national surveillance data includes all autologous OC cycles between 2012 and 2016. Cycles were divided into 4 distinct groups: cancer, elective, infertility, and medically indicated. We calculated trends and compared cycle and outcome characteristics between the 4 groups. We used multivariable log-binomial models to estimate associations between indication and gonadotropin dose, hyperstimulation, and cancelation and used Poisson regression models to estimate associations between indication and oocyte yield and maturity. RESULTS The study included 29,631 autologous OC cycles. Annual total (2925 to 8828) and cancer-related (177 to 504) cycles increased over the study period; the proportions remained constant. Compared to elective, cancer-related cycles were more likely to be performed among women < 35 years old, with higher BMI, living in the South, using an antagonist protocol. Compared to elective OC cycles, gonadotropin dose (aRR 0.89, 95%CI 0.80-0.99), cancelation (aRR 0.90, 95%CI 0.70-1.14), and hyperstimulation (aRR 1.46, 95%CI 0.77-2.29) were not different for cancer-related cycles. Oocyte yield and percent maturity were comparable in both groups. CONCLUSION The number of OC cycles among women with cancer has increased; however, the percentage OC cycles for cancer have remained stable. While patient demographic characteristics were different among those undergoing OC for cancer indication, cycle outcomes were comparable to elective OC. The outcomes of the subsequent oocyte thaw, fertilization, and embryo transfer cycles remain unknown.

Abstract
PURPOSE The aim of this study is to describe the multidisciplinary approach and controlled ovarian hyperstimulation (COH) outcomes in adolescent and young adult (AYA) patients (ages 13-21) who underwent oocyte cryopreservation for fertility preservation (FP). METHODS Multi-site retrospective cohort was performed from 2007 to 2018 at Northwestern University and Michigan University. Data were analyzed by chi-square test, t-test, and logistic regression. RESULTS Forty-one patients began COH of which 38 patients successfully underwent oocyte retrieval, with mature oocytes obtained and cryopreserved without any adverse outcomes. To treat this group of patients, we use a multidisciplinary approach with a patient navigator. When dividing patients by ages 13-17 vs. 18-21, the median doses of FSH used were 2325 and 2038 IU, the median number of mature oocytes retrieved were 10 and 10, and median number frozen oocytes were 11 and 13, respectively. Median days of stimulation were 10 for both groups. There was no statistical difference in BMI, AMH, peak E2, FSH dosage, days stimulated, total oocytes retrieved, mature oocytes retrieved, and oocytes frozen between the two groups. Three patients were canceled for poor response. CONCLUSION COH with oocyte cryopreservation is a feasible FP option for AYAs who may not have other alternatives when appropriate precautions are taken, such as proper counseling and having a support team. These promising outcomes correspond to similar findings of recent small case series, providing hope for these patients to have genetically related offspring in the future.
