Abstract
Organoid systems have revolutionised various facets of biological research by offering a three-dimensional (3D), physiologically relevant in vitro model to study complex organ systems. Over recent years, testicular organoids have been publicised as promising platforms for reproductive studies, disease modelling, drug screening, and fertility preservation. However, the full potential of these systems has yet to be realised due to inherent limitations. This paper offers a comprehensive analysis of the current challenges associated with testicular organoid models. Firstly, we address the inability of current organoid systems to fully replicate the intricate spatial organisation and cellular diversity of the in vivo testis. Secondly, we scrutinise the fidelity of germ cell maturation within the organoids, highlighting incomplete spermatogenesis and epigenetic inconsistencies. Thirdly, we consider the technical challenges faced during organoid culture, including nutrient diffusion limits, lack of vasculature, and the need for specialised growth factors. Finally, we discuss the ethical considerations surrounding the use of organoids for human reproduction research. Addressing these limitations in combination with integrating complementary approaches, will be essential if we are to advance our understanding of testicular biology and develop novel strategies for addressing reproductive health issues in males.

Abstract
Objective: While medical advances are enabling more children with cancer to live into adulthood, a large majority of them suffer from the late effects of treatment and about 30% experience infertility. Infertility impacts both male and female survivors complicating typical development for emerging young adults (EYAs) who typically spend this developmental period actively constructing their identities related to family and gender roles, attaining professional skills, and establishing social views. As literature is limited on identity formation and coping with infertility in young survivors, this study aimed to understand the experiences of childhood cancer survivors who are faced with infertility as a late treatment effect while reconstructing their identity. Method: A qualitative descriptive approach was used to explore the experiences and effects of childhood cancer complications on the identity development of six emerging adults (ages 18-29). Guided by the theoretical framework of identity development data were collected using semistructured interviews. Results: Four distinct themes emerged after the data analyses: restricted exploration and uncertain future, challenges to intimacy and communication, restructuring identity through redefining roles, and coping through familial support. Conclusions: Findings indicate that developmental processes of identity formation are complicated by the challenges stemming from infertility and require specific efforts to reconstruct core identity and redefine desired parental roles. Experimentation and self-discovery may be restricted for EYA cancer survivors as they reevaluate their views on intimate relationships, communication, potential professional roles, and family composition. Practical recommendations for multidisciplinary team members to support this growing population are discussed.

Abstract
PURPOSE Reproductive health is important, but often neglected in cancer survivorship care. This study explored contraceptive use and factors associated with fertility testing among young adult survivors of childhood cancer in Germany. METHODS Young adult survivors of childhood cancer were identified through the German Childhood Cancer Registry and completed a mailed survey. Survivors were queried regarding contraceptive use, reproductive goals, uncertainty about fertility, and completion or interest in fertility testing. Multivariable stepwise logistic regression models were used to calculate Odds Ratios (OR) and 95% confidence intervals (CI) as a means of identifying factors associated with completion of and interest in fertility testing. RESULTS Survivors (N = 472; 57.8% female; aged 23.3 ± 1.5 years, and 14.9 ± 5.0 years from diagnosis), reported high rates of contraceptive use, including 61.2% using a single method, 30.6% dual methods, and 8.1% no/less effective methods. Few survivors had completed fertility testing (13.0%), although 58.8% were interested. Having been diagnosed during adolescence (OR = 2.66, 95%CI: 1.39-5.09), greater uncertainty about fertility (OR = 1.16, 95%CI: 1.03-1.31), and use of dual contraceptive methods (OR = 1.94, 95%CI: 1.02-3.69) were associated with having completed fertility testing. Factors associated with interest in fertility testing included goals of wanting to have children (OR = 7.76, 95%CI: 3.01-20.04) and greater uncertainty about fertility (OR = 1.19 95%CI: 1.06-1.33). CONCLUSION In this sample of young adults who survived childhood cancer, most reported contraceptive use. Few survivors had completed fertility testing, although more than half were interested. Interventions are needed to address potential barriers to fertility testing and help survivors manage fertility-related uncertainty.

Abstract
In the survivorship setting, adolescent and young adult (AYA) cancer survivors frequently demonstrate little knowledge of infertility risk, are unclear regarding their fertility status, and may under- or overestimate their treatment-related risk for infertility. In female AYA survivors, ovarian function usually parallels fertility, and can be assessed with serum hormone levels and ultrasonography. Posttreatment fertility preservation may be appropriate for survivors at risk for primary ovarian insufficiency. In male AYA survivors, fertility and gonadal function are not always equally affected, and can be assessed with a semen analysis and serum hormones, respectively. As reproductive health issues are commonly cited as an important concern by survivors of AYA cancer, multidisciplinary care teams including oncology, endocrinology, psychology, and reproductive medicine are advocated, with the aim of optimal provision of fertility advice and care for AYA cancer survivors.

Abstract
Despite being considered "standard of care" by many organizations, fertility and reproductive health communications and counseling practices remain inconsistent for adolescents and young adults (AYAs) newly diagnosed with cancer and during survivorship. One factor known to affect how information is provided and received in the medical setting is health literacy. Providers should consider health literacy to optimize reproductive health communication with AYAs as they cope with their diagnosis, understand what it means for their future, process information about treatment options, learn about their potential harmful effects on fertility, make quick decisions about fertility preservation, and navigate a future family planning course. Thus, the objectives of this manuscript are to (a) summarize literature on reproductive health literacy; (b) describe health literacy frameworks; (c) examine ways to assess health literacy; and (d) identify ways to enhance clinician-patient communication in the AYA oncofertility setting.

Abstract
PURPOSE Cancer survivors with a history of gonadotoxic treatment are at risk for future infertility and reproductive concerns, including worry about infertility. The purpose of this study was to describe factors associated with fertility-related worry among emerging adult survivors of childhood cancer. METHODS This chart review included patients aged 18.00-25.99 years and > 1 year from cancer treatment completion with a history of gonadotoxic treatment. Survivors were offered structured fertility-focused discussions at age ≥ 18 years, which assessed worry about future infertility. Data from this discussion (i.e., reported fertility-related worry (yes/no), sociodemographic, and clinical characteristics were abstracted from the medical record. Multivariable logistic regression with backwards elimination was used to calculate odds ratios (OR) and 95% confidence intervals (95%CI) for factors associated with fertility-related worry. RESULTS Survivors (N = 249) were a mean age of 19.1 ± 1.2 years at initial fertility discussion; 55.8% were male, 58.2% non-Hispanic White, and 27.3% were at high risk for future treatment-related infertility. Fertility-related worry was reported by 66.3% of survivors. Factors related to worry on multivariable analysis included female sex (OR: 2.64, 95%CI: 1.44-4.96, p = .002), solid tumor diagnosis (OR: 2.31, 95%CI: 1.15-4.71, p = .019), moderate and high risk of infertility (OR: 2.94, 95%CI: 1.23-7.64, p = .02; OR: 3.25, 95%CI: 1.55-7.17, p = .002), and ≥ 2 fertility discussions during survivorship care OR: 2.71, 95%CI: 1.46-5.20, p = .002). CONCLUSIONS Two-thirds of emerging adult cancer survivors expressed worry about future infertility, which has been linked to a variety of adverse quality of life outcomes. Survivors who are worried about infertility may benefit from psychological interventions.

Abstract
Purpose: Increasing numbers of childhood cancer survivors enter adulthood and encounter decisions surrounding parenthood. However, limited research has systematically examined how childhood cancer may influence parenthood attitudes among survivors. Methods: Adult survivors of childhood cancer, who had or wanted to have children (N = 77; Mage = 30.2 years, range: 22-43; 91% White), rated their perceived impact of cancer at enrollment and parenthood attitudes using the "Attitudes to Parenthood After Cancer Scale" 2 years later. First, internal consistencies for the parenthood measure were examined, and modified subscales were proposed. Second, hierarchical stepwise regressions analyzed the contribution of background factors and cancer's impact on parenthood attitudes. Results: Reevaluation of parenthood items yielded four subscales with improved internal consistency (α's > .78): improved parenting due to cancer, no children due to cancer, concerns about a (potential) child's health, and parenthood desire irrespective of own health concerns. Already having children (n = 38) was related to more favorable ratings on most subscales. Older age was associated with perceiving improved parenting due to cancer (r = .24) and shorter time since diagnosis was related to considering having no children due to cancer (r = -.23). Hierarchical stepwise regressions reconfirmed parenthood status as related to more favorable parenting attitudes. Cancer preoccupation and perceiving cancer as a most difficult life experience predicted more concerns toward parenthood (R2 = .044-.216). Conclusions: Parenthood attitudes were more favorable among survivors with children, who were older, and/or further into survivorship. Survivors burdened by their cancer experience reported more concerns about parenthood. Childhood cancer may shape parenthood perceptions positively and negatively, warranting further research to inform interventions.

Abstract
BACKGROUND This study protocol describes the Fex-Can Childhood project, comprising two studies: The Fex-Can Childhood observational study (OS) and the Fex-Can Childhood randomized controlled trial (RCT). The Fex-Can Childhood OS aims to determine the prevalence and predictors of sexual dysfunction and fertility-related distress in young adult childhood cancer survivors (aged 19-40) compared to an age matched comparison group; the Fex-Can Childhood RCT will evaluate the effect of a web-based psycho-educational intervention (Fex-Can intervention) on sexual dysfunction and fertility-related distress. METHODS The Fex-Can Childhood OS will have a population-based cross-sectional design. All individuals treated for childhood cancer in Sweden at the age of 0 to 17 years (current age 19-40) will be identified through the National Quality Registry for Childhood Cancer. Established self-reported instruments will be used to measure sexual function, fertility-related distress, body image, anxiety and depression, and health-related quality of life. Self-efficacy related to sexual function and fertility, and fertility-related knowledge, will be assessed by study-specific measures. Clinical variables will be collected from the registry. Results will be compared to an age-matched comparison group from the general population.Participants in the Fex-Can Childhood OS who report a high level of sexual dysfunction and/or fertility-related distress will be invited to participate in the RCT. The Fex-Can intervention comprises two programs: The Fex-Can Sex and the Fex-Can Fertility targeting sexual dysfunction and fertility-related distress, respectively. The control condition will be a wait-list. Sexual function and fertility-related distress will be the primary outcomes. The secondary outcomes include body image, anxiety and depression, health-related quality of life and self-efficacy related to sexual function and fertility. Post- and follow-up assessments will be conducted directly after end of intervention (primary end point), at 3 months and 6 months after end of intervention. Additionally, a process-evaluation including study-specific items and a qualitative interview will be conducted. DISCUSSION The Fex-Can Childhood project will advance knowledge in the areas of sexual function and fertility-related distress among young adult survivors of childhood cancer. If the Fex-Can intervention proves to be efficacious, steps will be taken to implement it in the follow-up care provided to this population.

Abstract
Epidemiologic studies that include patients who underwent radiation therapy for the treatment of cancer aim to quantify the relationship between radiotherapy and the risk of subsequent late effects. Because of the long follow-up period required to observe late effects, these studies are conducted retrospectively. The studies routinely include patients treated across numerous institutions using a wide range of technologies and represent treatments over several decades. As a result, determining the dose throughout the patient's body is uniquely challenging. Therefore, estimating doses throughout the patient's body for epidemiologic studies requires special methodologies that are generally applied to a wide range of radiotherapy techniques. Over ten years ago, the MD Anderson Late Effects Group described various dose reconstruction methods for therapeutic and diagnostic radiation exposure for epidemiologic studies. Here we provide an update to the most widely used dose reconstruction methodology for epidemiologic studies, analytical model calculations combined with a 3D age-specific computational phantom. In particular, we describe the various adaptations (and enhancements) of that methodology, as well as how they have been used in radiation epidemiology studies and may be used in future studies.

PURPOSE To describe perceptions of infertility risk among adult survivors of childhood cancer, to test the concordance of survivors' risk perceptions and their adult fertility status, and to identify explanatory factors (sociodemographic factors, gonadotoxic treatments, reproductive history, sexual dysfunction) associated with these outcomes. PATIENTS AND METHODS Adult childhood cancer survivors (N = 1,067; without children or a history of pregnancies) completed questionnaires that asked about infertility risk perceptions and participated in physical evaluations, including biomarkers of gonadal functioning (eg, semen analysis, blood hormone levels, menses). Multivariable regression models tested associations between explanatory factors and risk perceptions as well as concordance of perceptions and fertility status. RESULTS Most childhood cancer survivors (61.9%) perceived themselves at increased risk for infertility, which was significantly associated with sociodemographic factors (older age, white ethnicity, being married/partnered, higher education), gonadotoxic treatments, fertility concerns, previous unsuccessful attempts to conceive, and sexual dysfunction (all P < .05). Laboratory-evaluated impaired gonadal function was found in 24.3% of female and 55.6% of male survivors, but concordance with survivors' risk perceptions was low (Cohen's κ < .19). Most survivors with discordant perceptions overestimated risk (ie, perceived being at risk, though fertility status seemed normal; 19.7% of male and 43.6% of female survivors), whereas a minority underestimated risk (ie, perceived no risk but were impaired/infertile; 16.3% of male and 5.3% of female survivors). Factors related to discordance included sociodemographics, gonadotoxic treatments, fertility concerns, and sexual dysfunction (all P < .05). CONCLUSION Although childfree survivors may correctly consider themselves at risk for infertility on the basis of their previous treatments, such risk perceptions were discordant from laboratory-evaluated fertility status among many survivors in adulthood. Thus, repeated fertility-related communication throughout survivorship is essential, because treatment-indicated risk does not equal fertility status after treatment. Offering fertility testing to those who were at risk and/or those with fertility-related concerns is recommended.

Abstract
Progress in overall survival rates for childhood non-Hodgkin lymphoma (NHL) can be largely attributed to effective development and conduct of a number of international treatment studies. Knowledge gained from these studies has shifted the treatment paradigm from a "one-size fits all" strategy to a histologically dependent approach. More specifically, many now adhere to a risk-stratified approach, prescribing cumulative doses and intensities of chemotherapeutic exposures based upon the aggressiveness of disease. Moreover, recognition that high cure rates could be achieved without the use of radiation has eliminated the use of this modality in frontline settings for the majority of newly diagnosed children. These changes have contributed to the emergence of a heterogeneous group of NHL survivors. As the number of NHL survivors continues to increase, providers will encounter a wide spectrum of individuals whose risk for long-term complications are accordingly diverse. The following review summarizes the existing literature surrounding late effects, such as chronic health conditions, functional and neurocognitive performance outcomes, and health-related quality of life, that are unique to NHL survivors, as well as those extrapolated from the broader childhood cancer survivor population.
