Our search strategies yielded 500 sites for evaluation. After excluding 227 duplicate websites, we assessed 273 websites for eligibility. Following eligibility screening, we determined 68 websites to be eligible for review (PRISMA diagram, Fig. 1). For a full breakdown of the review results, please see the Appendices 2–4.
Most of the 68 eligible websites were from general or pediatric hospitals (non-NCI Cancer Centers; n = 24, 35.3%) or cancer-related non-profits (22%, n = 15). Other websites were NCI Designated Comprehensive Cancer Centers (n = 9, 13.2%), fertility centers and sperm banks (n = 7, 10.3%), independent (e.g. non-academic, non-practice oriented) patient-facing websites or publications (n = 6, 8.8%), academic institutions (n = 5, 7.4%), and practitioner or research-based societies and institutions (i.e., ASCO or NIH; n = 2, 2.9%).
On average, these websites appeared as the 28th search result. Thirty-one websites (45.6%) were intended for AYA patients, 28 (41.2%) were intended for both patients and parents, and nine websites (13.2%) were solely aimed at parents or caregivers of AYA patients. Less than half (n = 31; 46%) of websites were solely dedicated to AYA patients.
Quality
According to the DISCERN measure of quality, the websites scored as Very Poor (n = 15, 22.1%), Poor (n = 29, 42.6%), Fair (n = 17, 25%), Good (n = 6, 8.8%), Excellent (n = 1, 1.5%) quality.
In terms of DISCERN questions on sites’ content, 57 websites (83.8%) scored low (i.e., 1–3, Appendix 2) to the question, "Does it refer to areas of uncertainty?", because they contained little information on uncertainty related to the experimental nature of certain treatment choices, unclear success rates for fertility preservation procedures in terms of successful collection of biological samples or a successful future attempt at pregnancy, or unknown benefits and risks of various procedures. For the question, “Is it clear what sources of information were used to compile the publication (other than the author or producer)?, the majority of sites scored low (n = 66, 97%), meaning they had few or no references to sources other than the author or producer. In response to the question, “Is it balanced and unbiased?”, nearly three quarters of sites (n = 47, 69.1%) scored low because they did not clearly indicate whether they were written from a personal or objective point of view, there was no evidence that a range of sources were used to inform the content, and there was no evidence of external review.
Readability
All websites were at or above a 9th grade reading level, and the average reading level for all websites was 12th grade. About half (n = 32, 47.1%) were at a college reading level (grades 13–14). Less than 10% (n = 5, 7.4%) were at a 9th grade reading level, 10.3% (n = 7) were at a 10th grade reading level, 10.3% (n = 7) at an 11th grade reading level, and 25% (n = 17) at a 12th grade reading level.
Desirability
The websites included an average of two out of the 21 AYA-generated desirable features. About a third of websites had one feature (n = 21, 30.9%) and (n = 2, 2.9%) had no features. The most common feature included was facts about fertility preservation, with almost all websites containing that information (n = 63, 92.6%). Almost half (n = 29, 42.6%) of websites included links to other fertility preservation sites or resources. Less than 20% of websites (n = 12, 17.6%) included survivor stories, had a question and answer section (16.2%, n = 11), or contained animations or videos (n = 12, 17.6%).
Inclusion Of Nccn Practice Guideline Topics
Of the 68 eligible sites, 13.2% (n = 9) were written solely for male patients, 29.4% (n = 20) were written for female patients, and 57.4% (n = 39) included both male and female content. Of the 48 websites with content for male patients, 89.5% (n = 43) mentioned sperm banking, 16.7% (n = 8) mentioned cyclic guanosine monophosphate-specific phosphodiesterase type 5 (PDE5) inhibitors or electro-ejaculation for patients with erection or ejaculation issues, and14.6% (n = 7) mentioned testicular sperm extraction (TESE). Of the 59 sites with content for female patients, 88.1% (n = 52) mentioned oocyte or embryo cryopreservation, 59.3% (n = 35) mentioned ovarian tissue cryopreservation, 28.8% (n = 17) mentioned menstrual suppression through medications like GnRH agonists, and 39% (n = 23) mentioned oophorexy or ovarian transposition.
Related to socioemotional topics recommended by NCCN, 39.7% (n = 27) of the 68 websites discussed costs related to fertility preservation, and few (n = 18, 26.5%) mentioned psychological or emotional considerations of fertility preservation. Notably, only 5.9% (n = 4) addressed additional complications for fertility preservation for transgender patients.
