LAUSANNE, Switzerland -- The United States will be under scrutiny at the IOC's year-end meeting because of several drug-related issues.

The scandal over the steroid THG, the impasse in Jerome Young's case and questions concerning government dues to the World Anti-Doping Agency will be addressed by the executive board Thursday and Friday.

On other matters, Olympic organizers will give a security update following last month's bombings in neighboring Turkey.

The International Olympic Committee's medical commission is expected to submit a proposal to allow transsexuals to compete in the Olympics for the first time.

Young, the reigning world 400-meter champion, tested positive for steroids in 1999 but was cleared on appeal by U.S. track officials.

Young won a gold medal with the U.S. 1,600-meter relay team at the Sydney Olympics. The IOC opened proceedings in September to determine if the team should be stripped of the medal.

IOC president Jacques Rogge said USA Track & Field has failed to supply documents explaining why Young was exonerated. Young has said he never committed a doping offense.

The IOC also will consider possible sanctions against the United States and other countries for nonpayment or late payment of annual WADA dues.

WADA chairman Dick Pound has criticized the Bush administration for failing to pay its 2003 share, which was due at the beginning of the year. He also said the government slashed its promised share from $1 million to $800,000; U.S. officials said the figure was always $800,000.

USOC president Bill Martin sent a letter to Rogge last week assuring him the government would make its payment in the next 60 to 90 days following passage of a bill in Congress. WADA is giving governments an extra six months, until June 30, to pay their shares for 2004.

The IOC board is meeting for the first time since the U.S. Anti-Doping Agency announced the unmasking of THG. Rogge said the IOC most likely will authorize the retesting of hundreds of samples for THG from the Salt Lake City Olympics.
