No end to gender questions for Semenya

CAPE TOWN - Caster Semenya is making a bold bid for double gold in the women's 800m and 1500m but her only guarantee at the World Athletics Championships in London is further scrutiny of the gender controversy that has dogged her career.

The powerful 26-year-old South African is the runaway favorite in the 800, where she seeks a third world title to add to her Olympic gold from Rio de Janeiro last year, and is taking on the 1500 for the first time at a major international meeting.

All of this, though, will come under a cloud of controversy at the Aug 4-13 championships as many feel high testosterone levels give her an unfair advantage.
