The 32-year-old claimed to have inadvertently taken EPO while visiting a hospital in Nairobi, Kenya, to be treated for an ectopic pregnancy six days before the failed drug test. She claimed to have received a blood transfusion and unidentified medication from an unknown doctor.
A doping tribunal found the testimony "inconsistent at best," according to the Anti-Doping Agency of Kenya.
"We might go so far as to state that the athlete's attempt to explain how the substance entered her body bordered on an attempt to deceive the panel," they said.
Sumgong was unable to name the doctor who treated her and the medical documents she provided were deemed fake by the hospital.
Her gold medal from the 2016 Rio Olympic Games will be unaffected and she will serve her ban starting from April 3, 2017, the date her provisional suspension was announced. She failed the drug test on Feb. 28 of this year.
