A detransitioner revealed in federal court filings that the pediatric urologist who told him puberty blockers weren’t causing bloody urine and incontinence is now facing six felony child pornography charges.
Jonni Skinner submitted a declaration Wednesday in the Federal Trade Commission’s lawsuit against the World Professional Association for Transgender Health, recounting how Dr. Bryan Sack dismissed alarming side effects when Skinner was a 15-year-old patient in 2018.
“Dr. Sack was arraigned on six felony charges related to possession of ‘child sexually abusive material'” in February, Skinner stated in the court document.
“My mother asked him if there were any connection between transition drugs and hematuria or incontinence. Dr. Sack insisted the answer was no. He said that these drugs had been used for decades.”
Skinner began seeing Sack after an endocrinologist at a gender clinic referred him to the urologist. The teenage boy was taking multiple transition drugs at the time, including the puberty blocker Histrelin.
While on the drug, Skinner’s urine became “strawberry colored” and appeared to “contain flakes of skin,” according to the declaration. He experienced urinary accidents at school, severe appetite loss, hot flashes, night sweats, genital pain and full-body muscle spasms that made riding his bike impossible.
Sack “did not give” Skinner “any useful advice or prescription” after the patient and his mother reported the side effects, the declaration states.

Federal authorities arrested Sack in early 2026 after executing a search warrant on his Michigan home. He pleaded not guilty in June to charges of receiving and possessing child pornography depicting a minor under age 12, according to local outlet WTOL.
Sack was working at Nationwide Children’s Hospital in Toledo, Ohio, which fired him immediately upon learning of the arrest. Investigators allegedly found multiple nude pictures of prepubescent minor females in sexually suggestive poses tied to an email address and screen name associated with Sack.
In Skinner’s medical chart, Sack wrote that he suspected the symptoms were “secondary to dysfunctional social voiding / holding onto urine” due to “issues with bathroom use at school.” The urologist used female pronouns when referring to Skinner in the chart.
After the diagnosis, Skinner’s school pushed the biologically male student to use the girls’ bathroom and cut off his access to the nurse’s office.
“Finally I got the puberty blocker removed from my arm in late 2018 when I was almost 16,” Skinner wrote. “Within a few months I stopped urinating blood.”
The Mayo Clinic lists dozens of possible side effects of Histrelin, including bloody and dark urine, as well as joint, muscle and chest pain.
Skinner describes himself as an autistic gay man who grew up in small-town Michigan. Children with autism are significantly overrepresented in the population of minors subjected to sex changes.
The FTC and the states of Alaska, Iowa, Nebraska and Texas filed their federal lawsuit against WPATH on Wednesday, alleging the transgender medical organization deceived minors into receiving sex changes for profit.
“WPATH has made false, misleading, or unsubstantiated statements—both in the SOC and other public-facing materials—regarding medical consensus and medical necessity, as well as the safety and efficacy of medical transition.”
In April, Skinner testified before the California Senate Judiciary Committee, confronting Democratic state Sen. Scott Wiener, a proponent of child sex changes now running for former Speaker Nancy Pelosi’s congressional seat.
“They poisoned my body with blockers and hormones, arresting my puberty and messing with my development,” Skinner told the committee. “The result? I’m a 23-year-old gay man who’s never had an orgasm and may never experience one.”
The charges against Sack remain allegations. The case has not been proven in court.
