A source close to Manny Ramirez(notes) said Thursday that the illegal substance for which the Los Angeles Dodgers slugger tested positive was not “an agent customarily used for performance enhancing.”
At least not on the baseball diamond. The source, who spoke on condition of anonymity, was prescribed to address Ramirez’s erectile dysfunction.
However, two sources said the substance Ramirez tested positive for a gonadotropin. Major League baseball’s list of banned substances includes the gonadotropins LH and HCG, which are most commonly used by women as fertility drugs. They also can be used to trigger testosterone production. Testosterone is depleted by steroid use, and low testosterone can cause erectile dysfunction.
“Testosterone and similar drugs are effective for erectile dysfunction in that they jazz up your sex drive,” said Charles Yesalis, a professor at Penn State who has testified before Congress on issues of performance-enhancing drugs. “But far more clinicians accept that affect with Viagra and Cialis. It’s hard for me to understand if it was erectile dysfunction why they would use it.”
