'Sexual performance' medication defense planned for Anderson Silva steroids hearing

UFC legend Anderson Silva's planned defense of his positive drug test results for banned substances involves something of a quite personal nature.

In two days, UFC middleweight and consensus all-time great Anderson Silva will finally appear at a Nevada Athletic Commission hearing to learn of his fate for multiple drug test failures before and after his win over Nick Diaz at UFC 183 on January 31st. Silva's team, as expected, will make a formal case for why Silva's drug test results were tainted and his name should be cleared of any wrongdoing.

The primary defense that Silva's lawyer, Michael Alonso, has laid out in the official complaint? Sexual performance medication produced the drostanolone metabolite that was found in Silva's out-of-competition and fight night samples.

MMA Fighting's Marc Raimondi has the details on the story, which was first posted by Combate:

"The Spider" tested positive for drostanolone metabolites twice -- once the day of his Jan. 31 fight against Nick Diaz and in an out-of-competition, Jan. 9 test. Silva also tested positive for androstane, another banned substance, in the random, pre-fight test.

Silva's lawyer Michael Alonso writes in the complaint that Silva was "administering or using a supplement for the purpose of enhancing sexual performance and testing of the supplement revealed that the supplement was contaminated with an Exogenous Anabolic Agent: Drostanolone metabolite."

Alonso also wrote that another supplement Silva was taking could have contained androstane.

Silva's defense against the NAC will also contain inconsistencies in drug tests, including two tests -- one pre-fight and one post-fight -- that Silva passed. The NAC did not include in its initial complaint the post-fight test that Silva had passed, according to the complaint.

Silva has repeatedly denied the PED use allegations, and earlier this week he said he was confident that he would get his name cleared. His post-fight drug test failures were for Oxazepam and Temazepam, which are generally used for anti-anxiety and insomnia. While those substances are not banned by the NAC, failing to disclose them to the commission beforehand -- in other words, using them without commission approval -- before the fight is prohibited.

Bloody Elbow will have live coverage of Anderson Silva's NAC hearing (plus any other MMA-related topics on the agenda list) on Thursday, August 13th at 11 AM ET/8 AM PT.
