From Mayo Clinic:
Possible side effects of GnRH analogue treatment (puberty blockers) include:
- Injection site swelling
- Weight gain
- Hot flashes
Use of GnRH analogues might also have long-term effects on:
- Bone density
- Future fertility
If children with male genitalia begin using GnRH analogues early in puberty, they might not develop enough penile and scrotal skin for certain gender confirmation genital surgical procedures, such as penile inversion vaginoplasty. Alternative techniques, however, are available.
In addition, delaying puberty beyond one’s peers can be stressful. Your child might experience lower self-esteem.
From Gender Dysphoria Alliance Canada (GDAC), an evidence-based education & advocacy network:
In some cases of severe Gender Dysphoria, medical treatments to change the appearance of our bodies can be helpful. These treatments can not change your biological sex, but they can masculinize or feminize your appearance, which is helpful for some people. This is a big decision. A medical transition is a very complex physical, social and psychological change, which can be extremely stressful. There are risks as well as benefits – which aren’t entirely predictable.
