Another sprinter Laverne Jones-Ferrette ran the fastest 60 metres in a decade in February, but was absent from outdoor competition in 2010. This was later explained by the revelation that she had failed a drug test for clomiphene on February 16. The substance can be used as a complement to steroid cycles, but can also act as a fertility drug and Jones-Ferrette (who announced her pregnancy in November) claimed this was the intended usage. She was banned from competition for six months, lasting from April to September, and lost her silver medal from the World Indoor Championships. Bobby-Gaye Wilkins won a relay medal for Jamaica at the same championships, but she was also stripped of her medal after testing positive for andarine – a selective androgen receptor modulator (SARM). A series of athletes were disqualified from the 2010 Commonwealth Games in New Delhi as a result of in-competition testing. Nigerians Samuel Okon and Oludamola Osayomi (the 100 m gold medallist) were banned for using the stimulant methylhexanamine. A third Nigerian, Folashade Abugan who won silver medals in the 400 m individual and relay races, failed a drug test for traces of testosterone prohormone and was stripped of her honours Indian racewalker Rani Yadav was also banned after testing positive for 19-Norandrosterone. Retired American sprinters Ramon Clay and Crystal Cox received retrospective bans from the United States Anti-Doping Agency due to their steroid usage relating to the BALCO scandal period from 2001 to 2004. Cox was stripped of her Olympic relay gold medal as a result. Former Jamaican runner Raymond Stewart was given a life ban from coaching for trafficking and administering banned substances as part of an ongoing investigation. Olympic Bahraini sprinter Roqaya Al-Gassra was banned for two years. Other prominent athletes to receive suspensions included South American triple jump champion Johana Triviño (two years for stanozolol), Asian indoor champion Munira Saleh (life ban for second violation with stanozolol), and 2010 CAC Games medallist Zudikey Rodríguez (methylhexanamine).
