Variables
subfertility
Three binary outcome variables described the attitudes towards OC as fertility preservation strategy. Affirmative answers (i.e., “totally/partially agree” or “yes, absolutely/maybe”) defined a positive attitude towards the general use OC, its public funding, and the hypothetic personal use in the allocated scenario. The WTP was treated as a continuous variable. Sociodemographic variables included age (categorized as ≤ 24, 25–29 or ≥ 30), country of birth (Sweden or other), region (major or other), field of university studies (Humanistic/Social, Science, Medical or Technical), employment (yes or no), monthly income (< 10 K, 10-19 K, 20-29 K, ≥ 30 K SEK), stable partner (yes or no). Three of the 21 Swedish regions were defined as major since they include the country’s major conurbations (Stockholm, Göteborg and Malmö). Reproductive experiences included previous pregnancy, live birth, and subfertility, addressed in dichotomous (yes or no) variables. Subfertility was defined as having sought medical assistance to get pregnant or having unsuccessfully attempted to conceive for at least one year. Indirect (experience of) subfertility was defined as acquaintance with someone having difficulties to get pregnant. Perceived knowledge regarding OC was self-rated from 1 to 5 (5 = best knowledge) before and after receiving information about OC, and final ratings were dichotomized as lower (< 3/5) or higher (≥ 3/5) knowledge. Interest for OC was captured by questions investigating thoughts and plans about the procedure. Attitudes towards oocyte donation and adoption were addressed in specific questions (i.e., “would you consider…?”) and open attitudes were defined by affirmative answers (“yes, absolutely” or “yes, maybe”).
