Really? No matter how long they are taken for? You're saying that someone blocking for years can just come off and things proceed normally?

Many countries are walking back the support for gender blockers -
Finland -
"Puberty blocking can cause serious physical side effects:
Potential risks of GnRH therapy include disruption in bone mineralization and the as yet unknown effects on the central nervous system. In trans girls, early pubertal suppression inhibits penile growth, requiring the use of alternative sources of tissue grafts for a potential future vaginoplasty. The effect of pubertal suppression and cross-sex hormones on fertility is not yet known."

France -
"Although, in France, the use of hormone blockers or hormones of the opposite sex is possible with parental authorization at any age, the greatest reserve is required in their use, given the side effects such as impact on growth, bone fragility, risk of sterility, emotional and intellectual consequences and, for girls, symptoms reminiscent of menopause.
As for surgical treatments, in particular mastectomy, which is authorized in France from the age of 14, and those involving the external genitalia (vulva, penis), their irreversible nature must be emphasized."

England -
"Puberty blockers (gonadotrophin-releasing hormone analogues) pause the physical changes of puberty, such as breast development or facial hair.
Little is known about the long-term side effects of hormone or puberty blockers in children with gender dysphoria.
Although GIDS advises this is a physically reversible treatment if stopped, it is not known what the psychological effects may be.
It's also not known whether hormone blockers affect the development of the teenage brain or children's bones. Side effects may also include hot flushes, fatigue and mood alterations."

The US is slowly waking it back -
"Use of GnRH analogues might also have long-term effects on:
Growth spurts
Bone growth and density
Future fertility — depending on when pubertal blockers are started
Children may have their height checked every three months. Bone density is also checked periodically. If bone growth or density is a concern, your child's health care provider might prescribe a different medication, stop treatment with GnRH analogues or recommend the best time to start cross-hormone therapy.
If children with male genitalia begin using GnRH analogues early in puberty, they might not develop enough penile and scrotal skin for certain gender affirming genital surgical procedures, such as penile inversion vaginoplasty. Alternative techniques, however, are available."
