Interindividual variation in ovarian reserve after gonadotoxic treatment in female childhood cancer survivors – a genome-wide association study: results from PanCareLIFE

ObjectiveWe aimed to discover new variants associated with low ovarian reserve after gonadotoxic treatment among adult female childhood cancer survivors using a genome-wide association study approach. DesignGenome-wide association study. SubjectsA discovery cohort of adult female childhood cancer survivors, from the pan‐European PanCareLIFE cohort (n=743; median age: 25.8 years), excluding those who received bilateral ovarian irradiation, bilateral oophorectomy, central nerve system or total body irradiation, or stem cell transplantation. Replication was attempted in the USA‐based St. Jude Lifetime Cohort (n=391; median age: 31.3 years). ExposureFemale childhood cancer survivors are at risk of therapy‐related gonadal impairment. Alkylating agents are well‐established risk factors, and the inter‐individual variability in gonadotoxicity may be explained by genetic polymorphisms. Data were collected in real-life conditions and cyclophosphamide equivalent dose was used to quantify alkylation agent exposure. InterventionNo intervention was performed. Main Outcome MeasureAnti‐Müllerian hormone (AMH) levels served as a proxy for ovarian function and findings were combined in a meta‐analysis. ResultsThree genome-wide significant (<5.0x10-8) and 16 genome-wide suggestive (<5.0x10-6) loci were associated with log-transformed AMH levels, adjusted for cyclophosphamide equivalent dose of alkylating agents, age at diagnosis, and age at study in the PanCareLIFE cohort. Based on effect allele frequency (EAF) (>0.01 if not genome-wide significant), p-value (<5.0×10−6), and biological relevance, 15 SNPs were selected for replication. None of the SNPs were statistically significantly associated with AMH levels. A meta-analysis indicated that rs78861946 was associated at borderline genome-wide statistical significance (Reference/effect allele: C/T; EAF: 0.04, Beta (SE): −0.484 (0.091), p‐value= 9.39×10−8). ConclusionThis study found no genetic variants associated with a lower ovarian reserve after gonadotoxic treatment, as the findings of this GWAS were not statistically significant replicated in the replication cohort. Suggestive evidence for potential importance of one variant is briefly discussed, but the lack of statistical significance calls for larger cohort sizes. As the population of childhood cancer survivors is increasing, large-scale and systematic research is needed to identify genetic variants that could aid predictive risk models of gonadotoxicity and as well as fertility preservation options for childhood cancer survivors.

Oocyte cryopreservation for women with endometriosis: Justification, indications, and reproductive outcomes.

Women with endometriosis often experience diminished ovarian reserve and a decreased number of oocytes retrieved. This reduction is exacerbated after surgery. Nevertheless, oocyte quality does not seem to be compromised in these patients. When embryos of good quality are obtained, in vitro fertilization outcomes are generally satisfactory. Oocyte cryopreservation may represent a fertility preservation option for women with planned and/or prior surgery, as it enables the collection of oocytes in advance. Given the diverse manifestations of endometriosis, which vary by type, age, and ovarian reserve, the decision to pursue oocyte cryopreservation should be weighed individually. Moreover, the potential benefits of this approach on future fertility must be carefully considered. Considering current guidelines, the most appropriate candidates for oocyte cryopreservation among women with endometriosis are: patients with bilateral endometriomas, typically larger than 3 cm; those with prior surgery for unilateral endometrioma who exhibit ipsilateral or contralateral recurrence; and those with unilateral endometrioma on a single ovary. However, the size criteria for endometrioma warrant further discussion. Conversely, oocyte cryopreservation is inadvisable for patients: with unilateral endometrioma smaller than 3 cm and good ovarian reserve; who have undergone surgery for bilateral endometriomas, regardless of recurrence; and who have diminished ovarian reserve. While consensus indicates that decisions regarding diminished ovarian reserve should be individualized, fertility preservation should often be considered for patients with serum anti-Müllerian hormone levels below 0.5 ng/mL. In such cases, a prolonged duration may be necessary to retrieve the desired 10 to 15 oocytes.

Reproductive Health in Trans and Gender Diverse Patients: Fertility related knowledge, attitudes, and decision-making among gender diverse youth - A narrative review.

Transgender and gender diverse (TGD) youth demonstrate low utilization of fertility preservation before medical and surgical gender-affirming interventions. However, a significant number of TGD youth have goals for parenthood and/or recognize that their attitude toward future family-building goals may change over time. In this narrative review, we conclude that TGD young people should have ongoing opportunities to discuss their family-building goals and options for fertility preservation. Validated decision tools can help facilitate these discussions. The number of transgender and gender diverse (TGD) youth seeking care continues to increase, necessitating comprehensive counseling about potential long-term effects of gender-affirming medical interventions on fertility. The objective of this narrative review was to examine fertility-related knowledge, attitudes, and decision-making (including factors influencing decisions, decision regret, and decision tools) among TGD youth. We searched PubMed, PsycInfo, and Google Scholar for original, peer-reviewed research investigating TGD youth attitudes and knowledge of fertility and fertility preservation, perspectives on fertility counseling and fertility preservation decision-making, as well as fertility-related decision tools. We reviewed 106 studies; eight were included in this narrative review. Four studies assessed TGD youth knowledge and attitudes of fertility and fertility preservation, three examined perspectives on fertility counseling and fertility preservation decision-making, and three discussed development of decision tools. Key findings were that: (1) many TGD youth are aware of potential fertility-related impacts of gender-affirming treatments, but there are still unmet informational needs, (2) some TGD youth report an interest in future biological parenthood, and of those who are not currently interested in biological parenthood, many acknowledge their desires may change over time, (3) ongoing discussions about fertility and fertility preservation are critical, and (4) decision tools are in development. In conclusion, TGD youth and their caregivers should receive ongoing, comprehensive fertility counseling and decision tools may be helpful to facilitate these discussions and decisions in each youth's gender-affirming care journey.

Current Fertility Preservation Steps in Young Women Suffering from Cancer and Future Perspectives.

Childhood cancer incidence, especially in high-income countries, has led to a focus on preserving fertility in this vulnerable population. The common treatments, such as radiation and certain chemotherapeutic agents, though effective, pose a risk to fertility. For adult women, established techniques like embryo and egg freezing are standard, requiring ovarian stimulation. However, for prepubescent girls, ovarian tissue freezing has become the primary option, eliminating the need for hormonal preparation. This review describes the beginning, evolution, and current situation of the fertility preservation options for this young population. A total of 75 studies were included, covering the steps in the current fertility preservation protocols: (i) ovarian tissue extraction, (ii) the freezing method, and (iii) thawing and transplantation. Cryopreservation and the subsequent transplantation of ovarian tissue have resulted in successful fertility restoration, with over 200 recorded live births, including cases involving ovarian tissue cryopreserved from prepubescent girls. Despite promising results, challenges persist, such as follicular loss during transplantation, which is attributed to ischemic and oxidative damage. Optimizing ovarian tissue-freezing processes and exploring alternatives to transplantation, like in vitro systems for follicles to establish maturation, are essential to mitigating associated risks. Further research is required in fertility preservation techniques to enhance clinical outcomes in the future. Ovarian tissue cryopreservation appears to be a method with specific benefits, indications, and risks, which can be an important tool in terms of preserving fertility in younger women.

Abstract 2233: Limited adherence to clinical practice guidelines on fertility preservation for patients with early-onset cancer

Abstract Background: ASCO Clinical Practice Guidelines on fertility preservation (FP) recommend that healthcare providers discuss the possibility of infertility—including FP options—for cancer patients of reproductive-age as early as possible before treatment initiation. However, the evaluation of patient perceptions on provider adherence to these FP guidelines is largely undetermined. We sought to assess patient-reported provider adherence to FP guidelines for adults ages 18 to 49 years when diagnosed with a first primary cancer (early-onset). Patients and Methods: The Reproductive Health After Cancer Diagnosis and Treatment (REACT) Study is a patient-partnered study in cooperation with 23 community partners and patient advocates. Adults with a first primary early-onset cancer were recruited over an 8-week period (October to December 2021). Patient-reported provider adherence to FP guidelines, reproductive health history, sociodemographic, cancer and cancer impact questions were prospectively collected via patient questionnaire using a secure, web-based application. To examine the association of provider non-adherence with patient-level factors, logistic regression models were fitted to estimate odds ratios (OR) and 95% CI. Results: Among 647 patients diagnosed with early-onset cancer between 2006 and 2021 (mean [SD] age, 36.8 [7.8] years), a total of 376 (58.1%) reported that a healthcare professional involved in their cancer care did not discuss FP options before starting cancer treatment. Patients with thyroid, lung, ovarian and colorectal cancers reported the highest rates of provider non-adherence to FP guidelines (all ≥63% non-adherence). Females with cervical (OR 2.87, 95% CI: 1.11-7.41), colorectal (OR 2.05, 95% CI: 1.15-3.68), lung (OR 15.79, 95% CI:5.66-44.1) and ovarian (OR 10.90, 95% CI: 3.19-37.3) cancers, Hodgkin (OR 4.00, 95% CI: 1.15-13.98) and non-Hodgkin lymphoma (OR 4.65, 95% CI: 1.11-19.47) were more likely to report provider non-adherence to FP guidelines compared to breast cancer patients in models adjusted for diagnosis age and year, self-reported race/ethnicity, marital status and insurance coverage at cancer diagnosis. Similar patterns were observed for male patients with early-onset colorectal and lung cancers compared with testicular cancer patients. No overall or sex-specific associations were observed between patient-reported provider non-adherence and race/ethnicity, insurance coverage or diagnosis year. Conclusions: Nearly six of every 10 early-onset cancer patients reported that a healthcare professional involved in their cancer care did not discuss FP options prior to cancer treatment. The development of tailored, effective strategies for implementation of clinical practice guidelines on FP and delivery of concordant reproductive healthcare to a growing population of reproductive-age individuals with cancer is needed.

Immune Checkpoint Inhibitors and Male Fertility: Should Fertility Preservation Options Be Considered before Treatment?

In recent years, immune checkpoint inhibitors (ICIs) have become a viable option for many cancer patients, including specific subgroups of pediatric patients. Despite their efficiency in treating different types of cancer, ICIs are responsible for a number of immune-related adverse events, including inflammatory toxicities, that can affect several organs. However, our knowledge of the impact of ICIs on the testis and male fertility is limited. It is possible that ICI treatment affects testicular function and spermatogenesis either directly or indirectly (or both). Treatment with ICIs may cause increased inflammation and immune cell infiltration within the seminiferous tubules of the testis, disturbing spermatogenesis or testosterone deficiency (primary hypogonadism). Additionally, the interference of ICIs with the hypothalamic-pituitary-gonadal axis may alter testosterone production, affecting testicular function (secondary hypogonadism) and spermatogenesis. This review provides an overview of the available evidence on the potential association between ICIs and the disruption of spermatogenesis, with special focus on ICIs targeting cytotoxic T-lymphocyte-associated protein 4 (CTLA-4), programmed death protein 1 (PD-1) and programmed death-ligand 1 (PD-L1). Moreover, it highlights the need for further investigations and encourages the discussion of associated risks and fertility-preservation considerations between clinicians and patients.

Ovarian Tissue Cryopreservation versus Other Fertility Techniques for Chemoradiation-Induced Premature Ovarian Insufficiency in Women: A Systematic Review and Future Directions.

Current advances in cancer therapy have increased survival, emphasizing the need for life quality improvement. Fertility loss is common post-chemotherapy. Current guidelines establish embryo and oocyte cryopreservation to address premature ovarian insufficiency (POI). Ovarian tissue cryopreservation has also recently become an acceptable option for fertility preservation, particularly as it is the only option for pre-pubertal patients. Few definitions for optimum fertility outcomes, and few systematic reviews comparing embryo, oocyte, and ovarian tissue cryopreservation as a means of fertility preservation (FP) in pre- and post-pubertal female cancer patients exist. This systematic review aims to improve understanding of gonadotoxic effects of chemoradiation therapy in cancer patients, to analyze the different fertility preservation techniques and procedures available to women with chemoradiation induced ovarian insufficiency, and to compare and recognize the benefits of each technique in restoring fertility, sexual hormone function, and quality of life. Searches were conducted electronically on PubMed, Cochrane, and EBSCOHost, including clinical trials, prospective, and retrospective studies of female cancer patients undergoing anti-cancer therapy, with predefined MeSH terminology. Data were collected, analyzed, and compared. Non-randomized clinical studies were evaluated for risk bias through the Newcastle-Ottawa Scale. In total, 23 studies were included. From there, 647 patients opted for oocyte cryopreservation, 267 for embryo cryopreservation, and 1382 for ovarian tissue cryopreservation (OTC). A total of 175, 18, and 121 live births resulted respectively from oocyte, embryo, and OTC, respectively. Studies without live births discussed other fertility markers as indicators of improvement in sexual hormone function and fertility. The gonadotoxic effects of chemotherapy call for FP intervention. Oocyte and embryo cryopreservation/implantation are well-established procedures. With changing trends and life quality consideration, OTC is a promising interventional method for pre-pubertal patients facing the prospect of fertility loss.

Pharmacological Protection of Ovaries During Program Drug Chemotherapy in Classical Hodgkin Lymphoma and Non-Hodgkin Lymphoma Patients

Aim. To assess the efficacy of ovarian protection and options for fertility preservation with the use of gonadotropin-releasing hormone agonists (a-GnRH) in patients with classical Hodgkin lymphoma (cHL) and non-Hodgkin lymphomas (NHLs) during program drug chemotherapy.&#x0D; Materials &amp; Methods. The study enrolled 247 female patients (187 with cHL and 60 with NHLs) undergoing program drug chemotherapy from 2019 to 2023. The patients were aged 13–42 years (median 24 years). Prior to chemotherapy and after it was completed, the serum anti-Mullerian hormone (AMH), follicle-stimulating hormone (FSH), and estradiol levels were measured. Besides, antral follicle count was estimated by pelvic ultrasound. To provide ovarian protection during chemotherapy, a-GnRH was administered to 67 (27 %) out of 247 patients. Ovarian reserve was assessed based on ultrasound and AMH, FSH, and estradiol levels in 2–3 months after completing the program of drug chemotherapy or after spontaneous menstrual recovery.&#x0D; Results. Menstrual cycle recovered in 194 (78.5 %) out of 247 patients, regardless of lymphoid malignancy variant. Among them, there were 79.7 % (n = 149) of cHL patients and 75 % (n = 45) of NHL patients. Accordingly, ovarian function was lost in 20.3 % (n = 38) of cHL patients and 25 % (n = 15) of NHL patients. Predictors of ovarian function recovery appeared to be age ≤ 28 years and AMH level &gt; 2.45 ng/mL. Pharmacological protection of ovaries did not impact the probability of menstrual cycle recovery. Regardless of immunomorphological variant of lymphoid malignancy, a regular menstrual cycle was completely restored in 48 (71.6 %) out of 67 a-GnRH recipients and in 146 (81.1 %) out of 180 patients without a-GnRH treatment.&#x0D; Conclusion. Most of cHL and NHL patients of early reproductive age (≤ 30 years) have a fair chance of menstrual cycle recovery after completing the program drug chemotherapy similar to BEACOPP, EACODD(PP)-14, R-CHOP, R-Da-EPOCH and other regimens. Ovarian reserve cannot be preserved by means of a-GnRH administration during chemotherapy. High baseline FSH and low baseline AMH levels indirectly indicate evidence of impaired ovarian reserve. Patients belonging to this category are those who, if intensive combined cytostatic therapy regimens are planned, should undergo prior oocyte/embryo retrieval with subsequent cryopreservation due to the risk of premature loss of ovarian function.

Fertility protection: a novel approach using pretreatment with mesenchymal stem cell exosomes to prevent chemotherapy–induced ovarian damage in a mouse model

BackgroundPrimary ovarian insufficiency (POI) refers to the loss of ovarian functionbefore the age of 40 years and results in amenorrhea and infertility. POI has diverse causes, but a common cause is exposure to gonadotoxic chemotherapy for cancer treatment. Due to the risk of developing POI, patients who want to preserve their fertility may consider various procedures for fertility preservation. However, current fertility preservation options are highly invasive, carry substantial risks, and have uncertain success rates. Recent studies from our group and others reported that mesenchymal stem cells (MSCs) and MSC-derived exosomes can restore ovarian functions in preclinical models of POI by restoring damaged cells and inhibiting apoptosis. Although the restorative effect of MSC-derived exosomes has been well reported in previous studies, the potential of MSC-derived exosomes for preventing ovarian damage has not been fully elucidated. ObjectiveWe hypothesized that the antiapoptotic potential of MSC-derived exosomes may protect ovarian tissue from chemotherapy-induced damage. Study designIn this study, we delivered MSC-derived exosomes directly into mouse ovaries before chemotherapy. Sixty mice were divided into three groups (20 per group), which were labeled the control, CTx (chemotherapy), and FP (fertility protection) groups. Only the FP group mice received exosomes, while the control and CTx group mice received saline. After exosome injection, the CTx and FP groups of mice were subjected to chemotherapy treatment to induce ovarian damage. After chemotherapy, we evaluated the protective effects of exosome treatment on ovarian function, such as estrus cyclicity, serum hormone levels, and the fertility rate, by comparing these outcomes between the CTx and FP groups. These outcomes were also compared with those of the control group for comparison with outcomes under healthy conditions. ResultsAfter intraovarian injection of exosomes before chemotherapy, the mice were able to maintain their estrus cycle (4–5-day cyclicity), serum AMH level (66.06±26.40 ng/ml, not significantly different from that of the healthy controls), folliculogenesis (32.2±11.3 in the CTx group/46.4±14.1 in the FP group, p<0.05), steroidogenesis marker StAR gene expression (0.44±0.11-fold in the CTx group and 0.88±0.31-fold in the FP group, p<0.05), and fertility (2 of 8 in the CTx group and 5 of 8 in the FP group), preventing chemotherapy-induced damage. We found that exosome treatment before chemotherapy can preserve ovarian function and protect fertility through the overexpression of ABC transporters, such as ABCB1b (10.17±17.75-fold in the CTx group and 44.14±33.25-fold in the FP group; p<0.05), and ABCC10 (3.25±0.59-fold in the CTx group and 5.36±1.86-fold in the FP group; p<0.05). ConclusionIn this study, we present a novel fertility protection method using MSC-derived exosomes. We conclude that MSC-derived exosomes are a promising simple treatment option for fertility protection in reproductive-age patients receiving gonadotoxic chemotherapy.

Perceptions and experiences of fertility preservation in female patients with cancer in Greece

BackgroundAs advances in oncology have led to remarkable and steady improvements in the survival rates of patients with cancer and anticancer treatment can cause premature ovarian failure in women, fertility preservation (FP) has become a global public health concern and an integral part of the care for women diagnosed with cancer during reproductive age. However, for various reasons, FP remains underutilized for patients with cancer. There are substantial gaps in our knowledge about women’s experiences and perceptions of the issue. This study aims to contribute to bridging that gap.MethodsThis prospective qualitative study was conducted from March 2018 to February 2023. A combination of purposive and snowball sampling was used. Data were collected by semistructured interviews with nineteen reproductive-age women who had been recently diagnosed with cancer. Data were classified and analysed with a thematic analysis approach.ResultsA variety of distinct themes and subthemes emerged from the analysis of the interview data. The cancer diagnosis emerged as a factor that considerably affects the women’s attitudes towards biological parenthood: It can further increase their (strong) previous desire or decrease their previous (weak) desire. Women with a recent cancer diagnosis had not received adequate and multidisciplinary counselling, including clear and sufficient information. However, participants felt satisfied with the information they received because they either received the information they requested or remained in denial about the need to be informed (i.e., because they felt overwhelmed after the cancer diagnosis). Embryo cryopreservation emerged as a less desirable FP option for women with cancer. Participants showed respect for human embryos, not always for religious reasons. Surrogacy emerged as the last resort for most participants. Religious, social or financial factors did play a secondary (if any) role in women’s decision-making about FP. Finally, male partners’ opinions played a secondary role in most participants’ decision-making about FP. If embryo cryopreservation was the selected option, partners would have a say because they were contributing their genetic material.ConclusionsThe findings that emerged from the data analysis were partly consistent with prior studies. However, we identified some interesting nuances that are of clinical importance. The results of this study may serve as a starting point for future research.

Controlled ovarian stimulation in cancer patients under 18 years old; a case series

BackgroundFertility 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 presentationThis 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.ConclusionsOocyte 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.

Impact of Systemic Therapy on Fertility in Women with Early-Stage Breast Cancer.

Fertility concerns are common among young women diagnosed with breast cancer, as systemic therapy increases the risk of premature ovarian insufficiency and delays family planning. Here, we review the impact of systemic therapies, including chemotherapy, endocrine therapy, HER-2 directed therapy, PARP inhibitors, and immunotherapy, on ovarian reserve. With an improved understanding of disease biology, fewer women are treated with gonadotoxic chemotherapy. There are limited data on the fertility impact of novel targeted treatments and immunotherapy, though preclinical and preliminary studies suggest an impact on fertility is possible. Notably, a recent study investigated the outcomes in women who interrupted adjuvant endocrine therapy to attempt pregnancy. Further research is needed to characterize the fertility impact of novel therapies in breast cancer. Individualized fertility counseling should be offered to all women to discuss the possible impact of therapy on ovarian reserve and options for fertility preservation and timing of pregnancy.

Knowledge and intentions to use fertility preservation among urban Chinese cancer patients: A study from Hong Kong.

To assess the knowledge levels and fertility preservation (FP) intentions of urban Chinese cancer patients. A cross-sectional study was conducted on Hong Kong Chinese male and female cancer patients aged 18-54 years (N = 325) who were recruited by a local non-governmental organization for cancer patients between July 2020 to January 2021. Patients completed a self-administered questionnaire on knowledge, perceptions, and intentions to use FP services/seek FP-related information. Multivariable logistic regression was used to explore the correlates of intention to seek additional FP information and intention to undergo FP treatments. Although cancer patients demonstrated a good knowledge of the available FP treatment options, they were less knowledgeable about the legal restrictions of these procedures. Only one in seven cancer patients first became aware of FP through a health provider and the majority of cancer patients felt they did not have adequate knowledge about FP to make informed FP decisions at the current time. Yet, over one-third of cancer patients would consider FP options even if their cancer or cancer treatment had < 5% chance of causing infertility, and 13.4% of females and 14.6% of males would delay their cancer treatment by ≥ 3 months to undergo FP procedures. However, for both sexes, the main perceived barrier to obtaining FP was its financial cost. Patients with older-aged spouses were less likely to seek FP treatments or seek more information about FP. There is an unmet need for more FP information and FP services for reproductive-aged cancer patients in East Asian populations. Greater integration of FP services into cancer treatment requires a reduction of cost barriers, greater provision of timely FP information, and improved referral systems.

Breast Cancer in Young African Women: Unique Challenges and Perspectives

Abstract Breast cancer (BC) in young women is difficult to treat, especially in Africa. This review discusses the gaps and frustrations clinicians face in South Africa and the broader sub-Saharan region. It provides a snapshot of the literature concerning young BC patients and their unique challenges, including age, ancestry, barriers to care, fertility and ovarian preservation options, access to genetic testing and counseling, clinician knowledge and attitudes and specific molecular subtypes. In addition, the review includes insights from specialist oncology surgeons working in the South African public and private healthcare sectors and calls for advocacy. There is an urgent need for multilayered systemic change in the care of young BC patients in sub-Saharan Africa to address the tragic reality of clinicians being unable to offer them the care they deserve.

Fertility Preservation in Patients With Cancer: Nurses' Views, Experiences, and Perceptions of Benefits and Barriers.

To evaluate nurses' views, experiences, and perceptions of the benefits and barriers to fertility preservation (FP) care for patients with cancer. The sample consisted of 236 nurses who provided care before gonadotoxic treatment for people with cancer in three university hospitals in Istanbul, Turkey, from January to June 2018. The data were collected using a participant information form and the Oncology FP Survey. The main research variables were nurses' views, experiences, and perceptions of benefits and barriers to FP care. Data were evaluated using means, SDs, frequencies, and the Mann-Whitney U test. Patients and their families were informed about FP most of the time. This information was given by physicians about half the time and by nurses less than one-fourth of the time. Mean scores on the Oncology FP Survey were moderate and indicated challenges among nurses in self-confidence, self-awareness of personal limitations, and perceived barriers when providing effective FP care. Nurses face challenges in providing counseling about FP options for patients with cancer and their families. Increasing self-confidence, reducing personal limitations, and decreasing perceived barriers to FP care through appropriate training may improve nurses' ability to provide FP counseling.

Comparative effects of a calcium chelator (BAPTA-AM) and melatonin on cryopreservation-induced oxidative stress and damage in ovarian tissue

Oncology treatments cause infertility, and ovarian tissue cryopreservation and transplantation (OTCT) is the only option for fertility preservation in prepubertal girls with cancer. However, OTCT is associated with massive follicle loss. Here, we aimed to determine the effect of supplementation of slow freezing and vitrification media with BAPTA-AM and melatonin alone and in combination on ovarian tissue viability, reactive oxygen species (ROS) levels, total antioxidant capacity (TAC), and follicular morphology and viability. Our results indicated that BAPTA-AM and melatonin can significantly improve ovarian tissue viability and the TAC/ROS ratio and reduce ROS generation in frozen-thawed ovarian tissues in slow freezing and vitrification procedures. BAPTA-AM was also found to be less effective on TAC compared to melatonin in vitrified ovarian tissue. While supplementation of slow freezing and vitrification media with BAPTA-AM and/or melatonin could increase the percentage of morphologically intact follicles in cryopreserved ovarian tissues, the differences were not significant. In conclusion, supplementation of cryopreservation media with BAPTA-AM or melatonin improved the outcome of ovarian tissue cryopreservation in both vitrification and slow freezing methods. Our data provide some insight into the importance of modulating redox balance and intracellular Ca2+ levels during ovarian tissue cryopreservation to optimize the current cryopreservation methods.

Fertility Protection, A Novel Concept: Umbilical Cord Mesenchymal Stem Cell-Derived Exosomes Protect against Chemotherapy-Induced Testicular Cytotoxicity.

Currently, there is no viable option for fertility preservation in prepubertal boys. Experimentally, controlled vitrification of testicular tissue has been evaluated and found to cause potential structural damage to the spermatogonial stem cell (SSC) niche during cryopreservation. In this report, we leveraged the regenerative effect of human umbilical cord-derived Mesenchymal stem cell exosomes (h-UCMSC-Exo) to protect against testicular damage from the cytotoxic effects of polychemotherapy (CTX). A chemotherapy-induced testicular dysfunctional model was established by CTX treatment with cyclophosphamide and Busulfan in vitro (human Sertoli cells) and in prepubescent mice. We assessed the effects of the exosomes by analyzing cell proliferation assays, molecular analysis, immunohistochemistry, body weight change, serum hormone levels, and fertility rate. Our data indicates the protective effect of h-UCMSC-Exo by preserving the SSC niche and preventing testicular damage in mice. Interestingly, mice that received multiple injections of h-UCMSC-Exo showed significantly higher fertility rates and serum testosterone levels (p < 0.01). Our study demonstrates that h-UCMSC-Exo can potentially be a novel fertility protection approach in prepubertal boys triaged for chemotherapy treatment.

Fertility preservation choices and decisional regret after gender-affirming surgery in transgender men or gender nonbinary persons

To investigate the prevalence of decisional regret regarding preoperative fertility preservation choices after gender-affirming surgery or removal of reproductive organs. Cross-sectional. University-based pratice. A total of 57 survey respondents identifying as transgender men or gender nonbinary with a history of gender-affirming surgery or removal of reproductive organs between 2014 and 2023 with the University of North Carolina Minimally Invasive Gynecology division. Survey or questionnaire. The prevalence and severity of decisional regret regarding preoperative fertility preservation choices were measured with the use of the validated decisional regret scale (DRS) (scored 0-100). Secondary outcomes included patient-reported barriers to pursuing reproductive endocrinology and infertility consultation and fertility preservation treatment. The survey response rate was 50.9% (57/112). "Mild" to "severe" decisional regret was reported by 38.6% (n = 22) of survey respondents, with DRS scores among all respondents ranging from 0-85. Higher median DRS scores were associated with patient-reported inadequacy of preoperative fertility counseling regarding implications of surgery on future fertility or family-building (0vs. 50) and fertility preservation options (0 vs. 12.5). No desire for future fertility at the time of fertility counseling was the most frequent reason (68.4%) for declining a referral to reproductive endocrinology and infertility for additional fertility preservation discussion. Decisional regret regarding preoperative fertility preservation choices is experienced among transgender men or gender nonbinary persons after gender-affirming surgery or the removal of reproductive organs. Preoperative, patient-centered fertility counseling and fertility preservation treatments should be provided to reduce the risk of future regret.
