Would you ban a child from accessing puberty blockers for precocious puberty? Or would you suggest that is a decision best made between the patient, their parent, and medical professionals?
Central precocious puberty (CPP) is what puberty blockers are actually licensed for for children. And the aim is for children to actually go through puberty. So puberty blockers are actually stopped in a reasonable time frame.
You can’t compare medical treatments if the goals are so diametrically opposed.
Puberty blockers for CPP: allow normal puberty.
Puberty blockers for GD: to completely prevent normal puberty.
Mastectomy for breast cancer: to remove diseased breast tissue.
Mastectomy for GD: to remove completely healthy breast tissue.
Testosterone for testosterone deficiency: to raise abnormally low testosterone levels into the normal range.
Testosterone for GD: to raise normal testosterone levels massively above the normal range.
Medicine: to help with disease and wellbeing.
Gender Medicine: to cause disease despite no evidence of benefit to wellbeing.
