15proportional font:
SB479,5,1616 NOTICE
SB479,5,2317 If your child begins one of these treatments, it may actually worsen the
18discordance and thus increase the likelihood that your child will need additional and
19more serious interventions to address the worsening condition. For example, if your
20child begins socially transitioning or taking puberty blockers, that treatment may
21significantly increase the likelihood that your child's discordance will worsen and
22lead to your child eventually seeking cross-sex hormones or even surgery to remove
23some of your child's body parts.
SB479,6,224 Sweden, Finland, and the United Kingdom have conducted systematic reviews
25of evidence and concluded that there is no evidence that the potential benefits of

1puberty blockers and cross-sex hormones for this purpose outweigh the known or
2assumed risks.
SB479,6,73 Medical authorities in Sweden, Finland, and the United Kingdom have since
4recommended psychotherapy as the first line of treatment for youth gender
5dysphoria, with drugs and surgeries reserved as a measure of last resort. Medical
6authorities in France have advised “great caution” when prescribing hormones for
7gender dysphoria.
SB479,6,138 There are people who underwent gender transition treatments as minors and
9later regretted that decision and the physical harm that these treatments caused,
10and the total percentage of people who experience this regret is unknown. Some
11estimate that the rate is below 2 percent, but that estimate is based on studies done
12on adults who transitioned as adults or on minors who transitioned under highly
13restrictive and controlled conditions.
