Clinical and ethical perspectives of ovarian stimulation and oocyte cryopreservation in adolescents: 6 years experience from a tertiary centre. Hum Reprod Open 2025; 2025:hoaf005. [PMID: 39959763 PMCID: PMC11825388 DOI: 10.1093/hropen/hoaf005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/31/2024] [Revised: 12/02/2024] [Indexed: 02/18/2025] Open
Abstract
STUDY QUESTION What are the clinical and ethical challenges of performing ovarian stimulation and oocyte cryopreservation in adolescents and the barriers to providing treatment? SUMMARY ANSWER Our study shows that, in one of the largest case series to date in this population, post-pubertal adolescents as young as age 13 years can undergo ovarian stimulation and oocyte cryopreservation with a response comparable to adults. WHAT IS KNOWN ALREADY Fertility preservation in adolescents has not been well studied, with little data available in the existing literature. Referrals for fertility preservation in adolescents are increasing due to developments in childhood cancer treatments, which have led to a growing population of children at risk of developing premature ovarian insufficiency. Those with certain benign conditions or gender incongruence also face this challenge. All established fertility preservation guidelines state that where there is a risk to fertility, oocyte cryopreservation should be offered to post-pubertal females. However, counselling and consenting young people about fertility decisions is an ethically complex area, and assessing capacity to consent in this age group is not straightforward. STUDY DESIGN SIZE DURATION This was a retrospective observational cohort study of 182 referrals for fertility preservation counselling to a specialist unit, and we present outcomes for the 33 adolescents who underwent 36 cycles of ovarian stimulation and oocyte cryopreservation between January 2018 and January 2024. PARTICIPANTS/MATERIALS SETTING METHODS We included patients aged 13-18 years who underwent ovarian stimulation and oocyte cryopreservation for fertility preservation due to high or intermediate risk of gonadotoxicity from medical or surgical treatment at a public-funded specialist unit. The primary outcome was oocyte yield; secondary outcomes included oocyte maturity rate, complications, and dropout rate. Data were retrieved from a prospectively managed database. MAIN RESULTS AND THE ROLE OF CHANCE There was a total of 182 referrals received, and of these, 33 patients underwent 36 cycles of ovarian stimulation and oocyte cryopreservation. Indications for fertility preservation included malignancy n = 19/36 (54%), ovarian cyst surgery n = 7/36 (19%), immunological disorders n = 4/36 (11%), benign haematological disease n = 2/36 (6%), gender reassignment treatment n = 3/36 (8%), and genetic conditions n = 1/36 (3%). The youngest child who underwent ovarian stimulation was aged 13 years and 10 months at the time of egg collection; the minimum time from menarche to ovarian stimulation was 4 months, the median AMH (anti-Müllerian hormone) was 16.7 pmol/l (range 2.8-36.9 pmol/l), and the antral follicle count (AFC) was 11 (3-36). The median number of cryopreserved oocytes was 14 (range 4-39), and the oocyte maturity rate was 85% (35-100%). Ultrasound monitoring was performed transabdominally in 5/33 (15%) and transvaginally in 28/33 (85%). Egg collection was performed transvaginally in all cases in this cohort. All cycles proceeded to completion. All adolescents were counselled in association with a family member to obtain informed consent, and all were assessed as able to comprehend discussions. LIMITATIONS REASONS FOR CAUTION In view of concerns regarding increased aneuploidy rates in this age group compared to women in their twenties, there is a need for long-term outcome studies expanding on our findings with data on livebirths to support clinicians needing to counsel patients and perform oocyte cryopreservation in adolescents. WIDER IMPLICATIONS OF THE FINDINGS Clinician experience, correct setting, and availability of funding will enable a permissive environment for oocyte cryopreservation in adolescents. In our experience, transvaginal egg collection is an accepted procedure when counselled appropriately. STUDY FUNDING/COMPETING INTERESTS No funding was received for this work. No competing interests are declared. TRIAL REGISTRATION NUMBER N/A.

Abstract
PURPOSE Fertility discussions are an integral part of comprehensive care for pediatric, adolescent, and young adult patients newly diagnosed with cancer and are supported by national guidelines. Current institutional practices are poorly understood. METHODS A cross-sectional survey was distributed to 220 Children's Oncology Group member institutions regarding fertility discussion practices. Descriptive statistics were calculated for all variables. The association between specific practices and selected outcomes on the basis of sex was examined via multivariable logistic regression. RESULTS One hundred forty-four programs (65.5%) returned surveys. Of these, 65 (45.1%) reported routine discussions of fertility with all female patients and 55 (38.5%) all male patients (P = .25). Ninety-two (63.8%) reported no specific criteria for offering females fertility preservation (FP), compared with 40 (27.7%) for males (P < .001). Program characteristics associated with fertility discussions included reproductive endocrinology and infertility on site (females odds ratio [OR], 2.1; 95% CI, 1.0 to 4.3), discussion documentation mandate (females OR, 2.3; 95% CI, 1.0 to 5.5; males OR, 3.5; 95% CI, 1.4 to 8.7), and cumulative institution-based FP infrastructure (which included [1] routine practice of documentation, [2] template for documentation, [3] mandate for documentation, and [4] availability of FP navigation; females OR, 1.6; 95% CI, 1.1 to 2.3; males OR, 2.3; 95% CI, 1.6 to 3.4). Utilization of practices unsupported by guidelines included offering sperm banking after treatment initiation (39/135 programs; 28.9%), gonadotropin-releasing hormone analogs for ovarian suppression/FP (75/144 programs; 52.1%), ovarian tissue cryopreservation at diagnosis for patients with leukemia (19/64 programs; 29.7%), and testicular tissue cryopreservation (23/138 programs; 16.7%) not part of a clinical trial. CONCLUSION Despite recommended guidelines, fertility discussions with patients/families before treatment initiation are not routine at Children's Oncology Group institutions. Standard criteria to determine which options should be offered to patients are more common for males than females.

Abstract
Striking advances in the treatment of Hodgkin lymphoma over the last 30 years have culminated in high rates of disease-free survival in younger patients with early and advanced stage disease. In this review we focus on strategies that have evolved over recent years to reduce short and long-term toxicities of treatment. These strategies include the selection of first-line chemotherapy, the stratification of patients based on initial response and subsequent adaptation of treatment, the addition of novel agents (e.g., brentuximab vedotin), the removal of specific drugs (e.g., bleomycin), the use of drug substitution, and the removal of consolidation radiotherapy based on interim and end of treatment PET assessment. While these strategies have successfully reduced toxicity of Hodgkin lymphoma therapy, the cornerstone of treatment continues to be combination chemotherapy and radiotherapy with significant short- and long-term side effects. To further reduce toxicity while maintaining or improving efficacy, we shall need to incorporate novel agents into our first-line treatment algorithms, and several such potentially practice-changing trials are underway.

Abstract
The germline cells are essential for the propagation of human beings, thus essential for the survival of mankind. The germline stem cells, as a unique cell type, generate various states of germ stem cells and then differentiate into specialized cells, spermatozoa and ova, for producing offspring, while self-renew to generate more stem cells. Abnormal development of germline stem cells often causes severe diseases in humans, including infertility and cancer. Primordial germ cells (PGCs) first emerge during early embryonic development, migrate into the gentile ridge, and then join in the formation of gonads. In males, they differentiate into spermatogonial stem cells, which give rise to spermatozoa via meiosis from the onset of puberty, while in females, the female germline stem cells (FGSCs) retain stemness in the ovary and initiate meiosis to generate oocytes. Primordial germ cell-like cells (PGCLCs) can be induced in vitro from embryonic stem cells or induced pluripotent stem cells. In this review, we focus on current advances in these embryonic and adult germline stem cells, and the induced PGCLCs in humans, provide an overview of molecular mechanisms underlying the development and differentiation of the germline stem cells and outline their physiological functions, pathological implications, and clinical applications.

Abstract
The assessment of the impact of chemotherapies on in vitro spermatogenesis in experimental models is required before considering the application of this fertility restoration strategy to prepubertal boys who received these treatments before testicular tissue cryopreservation. The present work investigated the effects of exposure of prepubertal mice to mono- (vincristine or cyclophosphamide) and polychemotherapy (a combination of vincristine and cyclophosphamide) on the first wave of in vitro spermatogenesis. When testicular tissue exposed to monochemotherapy was preserved, polychemotherapy led to severe alterations of the seminiferous epithelium and increased apoptosis in prepubertal testes prior in vitro maturation, suggesting a potential additive gonadotoxic effect. These alterations were also found in the testicular tissues of polychemotherapy-treated mice after 30 days of organotypic culture and were associated with a reduction in the germ cell/Sertoli cell ratio. The different treatments neither altered the ability of spermatogonia to differentiate in vitro into spermatozoa nor the yield of in vitro spermatogenesis. However, more spermatozoa with morphological abnormalities and fragmented DNA were produced after administration of polychemotherapy. This work therefore shows for the first time the possibility to achieve a complete in vitro spermatogenesis after an in vivo exposure of mice to a mono- or polychemotherapy before meiotic entry.

Abstract
Background Cryopreservation of ovarian tissue is a fertility-preservation option for women before gonadotoxic treatments. However, cryopreserved ovarian tissue transplantation must be performed with caution in women with malignancies that may metastasize to the ovaries. For this purpose, detecting minimal residual disease (MRD) in the ovarian cortex using sensitive methods is a crucial step. We developed an automated ovarian tissue dissociation method to obtain ovarian cell suspensions. Results We assessed MRD by multicolor flow cytometry (MFC) in cryopreserved ovarian cortex of 15 leukemia patients: 6 with B-cell acute lymphoblastic leukemia (B-ALL), 2 with T-cell acute lymphoblastic leukemia (T-ALL) and 7 with acute myeloid leukemia (AML). Ovarian MRD was positive in 5 of the 15 leukemia patients (one T-ALL and 4 AML). No B-ALL patient was positive by MFC. Quantitative reverse-transcribed polymerase chain reaction was performed when a molecular marker was available, and confirmed the MFC results for 3 patients tested. Xenografts into immunodeficient mice were also performed with ovarian cortical tissue from 10 leukemia patients, with no evidence of leukemic cells after the 6-month grafting period. Conclusions In conclusion, this is the first study using MFC to detect MRD in ovarian cortical tissue from acute leukemia patients. MFC has been accepted in clinical practice for its ease of use, the large number of parameters available simultaneously, and high throughput analysis. We demonstrate here that MFC is a reliable method to detect MRD in cryopreserved ovarian tissue, with a view to controlling the oncological risk before ovarian tissue transplantation in leukemia patients.

Abstract
Recent advances in early detection and oncological therapies have ameliorated the survival rate of young cancer patients. Yet, ovarian impairment induced by chemotherapy and radiotherapy is still a challenging issue. This review, based on clinical and lab-based studies, summarizes the evidence of gonadotoxicity of chemoradiotherapy, the recent approaches, ongoing controversies, and future perspectives of fertility preservation (FP) in female patients who have experienced chemo- or radio-therapy. Existing data indicate that chemotherapeutic agents induce DNA alterations and massive follicle activation via the phosphoinositide 3-kinase (PI3K)/Akt signaling pathway. Meanwhile, the radiation causes ionizing damage, leading to germ cell loss. In addition to the well-established methods, numerous therapeutic approaches have been suggested, including minimizing the follicle loss in cryopreserved ovarian grafts after transplantation, in vitro activation or in vitro growing of follicles, artificial ovarian development, or fertoprotective adjuvant to prevent ovarian damage from chemotherapy. Some reports have revealed positive outcomes from these therapies, whereas others have demonstrated conflictions. Future perspectives are improving the live birth rate of FP, especially in patients with adverse ovarian reserve, eliminating the risk of malignancy reintroducing, and increasing society’s awareness of FP importance.

Multidisciplinary consensus on the criteria for fertility preservation in cancer patients. Clin Transl Oncol 2021; 24:227-243. [PMID: 34635959 PMCID: PMC8794945 DOI: 10.1007/s12094-021-02699-2] [Citation(s) in RCA: 18] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/26/2021] [Accepted: 08/14/2021] [Indexed: 11/16/2022]
Abstract
Infertility is one of the main sequelae of cancer and its treatment in both children and adults of reproductive age. It is, therefore, essential that oncologists and haematologists provide adequate information about the risk of infertility and the possibilities for its preservation before starting treatment. Although many international clinical guidelines address this issue, this document is the first Spanish multidisciplinary guideline in paediatric and adult oncological patients. Experts from the Spanish Society of Medical Oncology, the Spanish Fertility Society, the Spanish Society of Haematology and Haemotherapy, the Spanish Society of Paediatric Haematology and Oncology and the Spanish Society of Radiation Oncology have collaborated to develop a multidisciplinary consensus.
