Girls treated in childhood with GnRHa have normal BMI, BMD, body composition, and ovarian function in early adulthood. FH is not increased in girls with ICPP in whom GnRHa was initiated at about 8 yr. There is no evidence that GnRHa treatment predisposes to polycystic ovary syndrome or menstrual irregularities.
I also want to say here that I have known two kids to be on blockers. Both had to drive several hours out of state to access their treatment. One of them almost was removed from their home by the state solely because they were trans and receiving blockers - a family friend who has received death threats and harassment and has had to go to court several times because she recognizes her son for who he is. The right wing propaganda sphere likes to pretend blockers are being handed out like candy, but that is not the case.
This study on several cis girls suggests that there’s nothing unusual about puberty post blockers.
