Introduction

Puberty blockers, or hormone blockers, are medicines used to delay puberty in children. Most puberty blockers suppress the natural production of sex hormones, namely testosterone and estrogen. Historically, puberty blockers were given to children who were starting puberty at too early an age. In recent years, puberty blockers have been given to transgender children, with the intention of delaying or stopping the advancement of puberty for transgender purposes.
Conservative perspective
Conservatives are typically against the use of puberty blockers for transgender considerations
One of the key arguments put forth by conservatives is that puberty blockers may have potential long-term risks and side effects, such as loss of bone density, which raises concerns about the overall health of transgender youth.
Conservatives have also raised concerns about the use of puberty blockers in relation to transgender athletes, arguing that it may provide an unfair advantage to transgender girls competing in girls’ sports. However, studies and experts’ opinions differ on the impact of puberty blockers on athletic performance, with some arguing that the medication levels the playing field while others contend that more research is needed to fully understand its effects on athletic performance.
