“…We hope to contribute to a worthwhile and meaningful variable selection by sensitising researchers to the importance of perceived benefits and barriers related to the health services assessed, perceived susceptibility for the condition assessed, previous experiences, sociocultural, environmental, and other factors influencing the value of a health technology. For example, cultural aspects will help interpret differences in WTP between countries if social desirability, shaped by moral values of a society [30], and perceived stigma by society [86], as motivations for use, differ. The monetary value of WTP and well-chosen determinants provide important information for policymakers to understand what determines the value of a health technology for the public.…”

Introduction Stated preference studies are a valuable tool to elicit respondents' willingness to pay (WTP) for goods or services, especially in situations where no market valuation exists. Contingent valuation (CV) is a widely used approach among stated-preference techniques for eliciting WTP if prices do not exist or do not reflect actual costs, for example, when services are covered by insurance. This review aimed to provide an overview of relevant factors determining WTP for health services to support variable selection. Methods A comprehensive systematic literature search and review of CV studies assessing determinants of WTP for health services was conducted, including 11 electronic databases. Two of the authors made independent decisions on the eligibility of studies. We extracted all determinants used and related p values for the effect sizes (e.g. reported in regression models with WTP for a health service as outcome variable). Determinants were summarised in systematic evidence tables and structured by thematic domains. ResultsWe identified 2082 publications, of which 202 full texts were checked for eligibility. We included 62 publications on 61 studies in the review. Across all studies, we identified 22 WTP determinants and other factors from 5 thematic domains: sociodemographic characteristics, perceived threat, perceived benefit, perceived barriers, and other information. ConclusionOur review provides evidence on 22 relevant determinants of WTP for health services, which may be used for variable selection and as guidance for planning CV surveys. Endogeneity should be carefully considered before interpreting these determinants as causal factors and potential intervention targets.

“…The issue of low usage is longstanding, with several studies attributing it to a lack of information (Korte et al 2020b ; Schover et al 2002 ). Nevertheless, awareness regarding fertility protection for cancer patients has changed in recent years (Gonen 2021 , Bizet et al 2012 ). This shift has also prompted the introduction of reimbursement for cryopreservation by health insurance companies in Germany in 2021.…”

Purpose We assessed factors that affect the utilization of sperm cryopreservation before 2021, when patients covered expenses, and the influence on quality of life. Methods Between 2011 and 2021, testicular cancer survivors (TCS) at our clinic completed a questionnaire, including EORTC QLQ-TC26, covering sperm cryopreservation, sociodemographic details, post-treatment births, and artificial insemination. Results After 5.7 ± 3.0 years, 279 participants (64%) responded to the questionnaire. Among them, 33% (91/279) of testicular cancer survivors chose sperm cryopreservation prior to treatment, with 11% (10/91) using it for insemination. Conversely, 2% (3/188) without cryopreservation reported unfulfilled desire to have children. Univariate analysis showed TCS with cryopreservation were younger (30.6 ± 7.1 (35 (21–59)) vs. 42.4 ± 10.9 (48 (22–81)) years; p = 0.001), had a lower BMI (24.2 ± 3.3 vs. 26.6 ± 4.6 kg/m2; p = 0.009) and a lower Charlson Score (> 3: 36% vs. 60%; p < 0.001). Multivariate analysis revealed older age (≥ 37 years: OR 13.1 (5.5–31.2), p < 0.001) and lower education (middle school or less: OR 3.3 (1.6–6.9), p = 0.001) as independent factors associated with not undergoing cryopreservation. Regarding quality of life, multivariate analysis identified a lower infertility anxiety score (OR 4.3 (2.0–9.0), p < 0.001) and higher age (≥ 44 years: OR 5.4 (2.6–11.3); p < 0.001) as predictors for the absence of prior cryopreservation. Conclusions Age and education seem to impact the choice of undergoing paid sperm cryopreservation. Urologists should inform testicular cancer patients about costs and coverage. Importantly, the occurrence of unmet desires for parenthood is minimal among those who forego cryopreservation.

“…Accumulation of cryopreserved sperm over time incurs medical and legal responsibilities, as well as financial expenses that are not fully covered by patients, families, insurance, and regulatory authorities. 5 From ethical and practical perspectives, patient consent prior to cryopreservation should include data related to plans for use, with possible relation to personal characteristics such as age, marital and paternal status, and the indication for preservation. For the best of our knowledge, these considerations are not included in any cryopreservation guidelines.…”

BackgroundThe wide implementation of sperm freezing presents a growing burden on sperm banks.ObjectivesTo evaluate sperm freezing and usage patterns over 30 years, according to demographic parameters of age at first cryopreservation and number of children, and indication for cryopreservation.Material and methodsThis retrospective, population based, cohort study included all sperm cryopreservation cases performed at a tertiary referral center from October 1993 to December 2021, among patients aged 18 years and older. First, we determined the interval between first sperm sample and use. Then, we examined sperm usage separately for: (1) age, comparing patients grouped into 5‐year age cohorts; (2) paternal status according to number of children; (3) indication, comparison among seven indications. Secondary analysis included correlations between main age groups and paternal status versus the four most common indications found.ResultsDuring the study period 1490 men who cryopreserved sperm met the inclusion criteria. Average age at cryopreservation of the first sample was 33.9 ± 8.1 years. Average age at first sperm use was 37 ± 8.5 years. Cumulative sperm usage was 38.7% after 17.8 years. Increasing age was associated with progressive increase in sperm usage rate and shorter preservation period. Use significantly decreased with increasing number of children. Examination of seven reasons for sperm cryopreservation found the highest cumulative sperm usage was related to azoospermia (67.7%), followed by functional cryopreservation (39.3%), oligoasthenoteratospermia (27.3%), other (26.5%), patient's request (24%), cancer (19%), and systemic disease (7.2%). Secondary analysis defined specific usage patterns mainly related to age and indication, with less of an effect based on the number of children.Discussion and conclusionAfter decades of cryopreservation, the paradigm of sperm cryopreservation is mostly related to cancer patients. This should be reevaluated and evolve to include broader patient‐targeted factors and perceptions.
