A detransitioned woman who is suing the medical professionals responsible for her transition claims doctors spent just 75 minutes vetting her before setting out on the life-altering ordeal - back when she was just 12 years old.

Now 18, Kayla Lovdahl filed the lawsuit last week in California's San Joaquin County Superior Court, accusing multiple Bay Area professionals of fast-tracking her treatment - while flouting factors such as her poor mental health.

It specifically names doctors Lisa Kristine Taylor, Winnie Mao Yiu Tong, Susanne Watson, and Mirna Escalante as defendants, for providing Lovdahl with puberty blockers, testosterone, and a double mastectomy in the span of just a few months.

Instead of warning Lovdahl about the finality of the treatment - or advising her to explore her gender issues through psychotherapy - the providers automatically, and erroneously, declared the youth to be transgender, the suit claims.

Also named in the sensational suit - which comes amid a growing chorus of 'detransitioning' youths expressing regret over their life choices - is the hospital who removed her breasts, and the provider who presided over the six-month process.

Lovdahl and her lawyers write their prognosis was premature - and gave the then-impressionable preteen the 'erroneous belief' she was transgender.

To come to that conclusion, the suit states, clinical psychologist Watson - who also serves as the clinical director of Kaiser Foundation Hospitals' 'Transgender Clinic' at the Oakland Medical Center - held a single, 75-minute transition evaluation.

During the sit-down, Watson is said to have not disclosed any of the lasting health risks associated with a young child taking 'off-label puberty blockers and high doses of powerful male hormone drugs' - after discerning Lovedahl was transgender.

Taylor and Tong, a endocrinologist and plastic surgeon employed under the Oakland-based hospital system's umbrella, all agreed with their colleagues' assessment, starting her on puberty blockers and testosterone at age 12.
