Mathis' Atlanta-based physician, identified as Steven Morganstern by [Mathis' agent, Hadley Engelhard], prescribed the fertility medication for Mathis, who began taking it in November. His wife was unable to take the drug because of a medical condition that would make multiple births extremely dangerous, according to White. Multiple births are more likely when fertility drugs are used; the Mathis' twin two-year-old sons were conceived through such treatments, according to [Denise White, CEO of EAG Sports Management and a spokesperson for Mathis].
The drug produced the desired results — Mathis' wife became pregnant — but Mathis had not checked with the NFL or NFL Players Association to determine whether the drug was allowed under the league's PED policy. ...
In a statement released through the union, Mathis, 33, said he asked his physician whether the fertility drug would create a problem with the NFL.
"Unfortunately, he incorrectly told me that it would not," Mathis said in the statement. "I made the mistake of not calling the NFL or NFLPA to double check before I took the medication at the end of last season.
