For UFC fans who are unfamiliar, lactating essentially means secreting milk from the breasts.
"This is one of the guys that really have authentic technical reasons to be on TRT," Silva's manager, Alex Davis said on Monday's edition of The MMA Hour. "He has acromegaly. His pituitary gland overproduces GH (growth hormone) and that unbalances all his other hormones.
"When I started managing him, he was actually lactating. He has extreme low testosterone. He has extremely low testosterone, so he has a real reason to be on TRT."
Silva was granted a therapeutic use exemption (TUE) for testosterone replacement therapy (TRT) for his fight against Mark Hunt, but he apparently took a few shots too many.
The extra shots pushed his testosterone levels over the accepted maximum limit, and that led to him being suspended nine months.
Davis says Silva was not trying to cheat the system. He explained that the Brazilian simply read instructions wrong.
"I didn’t really take part on the TRT process," Davis said. "There was a miscommunication between him and his doctor. If I was in the middle of it maybe we would have avoided it. I didn’t realize I needed to be involved."
"He took the instructions wrong, but he did not try to cheat," he continued. "What happened was, there was a miscommunication with the doctor and he ended up taking injections at the wrong time. He was taking (once) a month then started taking (once) a week. He took one a week before the fight and one at the week of the fight, which wasn’t supposed to. It got mixed up."
Silva, who reportedly considered retiring following his fight with Hunt, plans to continue testosterone replacement therapy for his future UFC bouts.
