A Texas father who tried for years to stop his ex-wife from allowing his pre-teen child, who now identifies as 'Luna,' to be chemically castrated has been dealt a blow in California court.

Los Angeles Superior Court Judge Mark Juhas ruled that Jeff Younger's ex-wife Anne Georgulas would be granted full custody of his 12-year-old son James and would be able to allow him to transition.

It comes as a blow to Younger, 59, who announced on X that he 'lost all parental rights' over his twins and wished his children goodbye. 

'Goodbye, boys. Perhaps, we will meet when you are adults,' he said in the post. 

He was granted 'supervised' visitation, but the father said he 'won't do that.' 

Younger said he does 'send letters and gifts to my sons,' but his ex-wife is not required to make sure the boys receive them. 

'Let my story be a cautionary one for young men. Fathers have no rights to their children. Do not enter the family law system,' he said. 'California Judge Juhas gave my ex-wife authority to castrate my son, James.' 

Chemical castration involves a child taking puberty-blocking medication to stop the sex hormones from being produced. It is not the same as surgical castration.

Chemical castration is reversible, but the side effects of long-term usage of hormones blockers is currently unknown. 

Last year, Younger begged his ex-wife not to chemically castrate their son after she moved to California. 

Younger revealed a video of his child claiming he's a girl on Tucker Carlson Tonight. When asked if he was a boy, James told his dad in the video: 'No, I'm a girl.'

In the video, which is several years old, the young boy claimed his mother, who is a pediatrician, told him he was female because he 'loved girls' and would dress him up in 'dresses.'

He claims Georgulas moved to California from Texas to seek gender treatment for their son in 2022. 

A court has previously ruled Georgulas cannot seek 'transitioning' treatment of their son and she has 'freely acknowledged' the order. The Supreme Court of Texas ruled in December 2022 that she 'lacks the legal authority to consent to such therapy.'
