Fertility Desires and Reproductive Needs of Transgender People

Description of the construct and its evaluation is detailed in the section "primary outcome measure" as follows:

A cross-sectional anonymous survey developed in the University Hospital of Nancy. Content validity of the questionnaire is endorsed by 2 endocrinologists specialized in transgender health (EF, VP). The first part provides general information on the characteristics of respondents (9 items). The second part concerns knowledge on fertility preservation (10 items), parental desires and constraints (8 items) and attitudes on fertility preservation issues (6 items). A descriptive analysis of the sample will be done using mean and standard deviation (or median and interquartile range) for quantitative variables, and counts and percentages for qualitative variables. The approval by the Institutional Review Board of the University Hospital of Nancy and the registration at French National Commission for Data Protection and Liberties are underway.

Questionnaire (Short form 36 health survey) The SF-36 is a generic quality of life self-questionnaire with 36 items grouped in 8 dimensions (physical functioning, limitations due to physical state, pain, mental health, limitations due to mental state, social health, vitality and global health). For each dimension a quality of life score is calculated and normalized between 0 (worst possible QoL) and 100 (best QoL possible).

• The STAI-Y assesses anxiety as a personality trait and as a specific emotional response to a situation. The first part, STAI-Y-1, consists of 20 sentences assessing the current emotional state of the subject. The second part, STAI-Y-2, consists of 20 sentences assessing the subject's usual emotional state.
• Each answer to an item in the STAI-Y is scored from 1 to 4, with 1 indicating the lowest degree of anxiety and 4 the highest degree of anxiety.
• In the STAI-Y-1, the subject indicates the intensity of his feelings on a 4-point Likert scale ranging from "not at all" to "many". In the STAI-Y-2, the subject indicates on a 4-point Likert scale ranging from "almost never" to "almost always", a frequency at which he usually feels the symptoms listed.
• To obtain the score for the STAI-Y-1, the scores for the 20 items (1 to 20) are summed. To obtain the STAI-Y-2 score, the scores for the 20 items (21 to 40) are summed. Each score can therefore vary from 20 to 80.

• The PSI-25 is an inventory of self-esteem relating to the body domain.
• This tool consists of 6 scales: at the general level, the overall self-esteem scale, at the physical domain level: the perceived physical value scale, and at the subdomain level, 4 subscales: the fitness, athletic competence, physical appearance and strength. It has 25 items
• The subject responds on the Likert scale in 6 increasing degrees (it looks like me 1: not at all, 2: very little, 3: a little, 4: enough, 5: a lot, 6: quite).
• The score ranges from 5 to 30 for each scale, total score is averaged.

• The CES-D assesses the frequency and severity of depressive symptoms presented by the general population. The questionnaire has 20 items.
• The subject indicates on a 4-point Likert scale ranging from "almost never" to "almost always", a frequency at which he usually feels the symptoms listed.
