Doctor Says Chael Sonnen's Initial Diagnosis of Hypogonadism Wasn't Definitive

He needs TRT now though...
A doctor who has reviewed Chael Sonnen's medical history says that while he now needs to use prescribed testosterone to compete, his initial diagnosis saying that he required it was not definitive. University of Arizona endocrinologist Karen Louise Herbst wrote a letter to Sonnen's management which was forwarded onto the Nevada State Athletic Commission as part of Sonnen's request for TRT to compete at UFC 167, concluding that Sonnen meets the criteria for TRT and is "likely permanently hypogonadal" due to his use of prescribed testosterone since 2008.
Herbst wrote, "It may be that suppression of his gonadal axis for that long may never allow a return to normalcy, and discontinuing his testosterone use at this time would be very disruptive to his career." She also noted that the initial diagnoses of testosterone deficiency was based on initial data and that it is "not clear that there was a definitive (without a doubt) diagnosis of hypogonadism."
According to NSAC Executive Director Keith Kizer, Herbst was referred to Sonnen by the UFC and would be reviewing fighters' medical histories for the UFC in the future. However, UFC Vice President of Regulatory Affairs Marc Ratner said the UFC wasn't involved and that Herbst was Sonnen's doctor.
Sonnen and his management did not respond to requests for comment on the story. Sonnen was granted a TRT extension for UFC 167, where he lost to Rashad Evans in the first round via TKO.
