Women want 'offending' rule removed

The rule applies to events from 400m to the mile, including 400m, hurdles races, 800m, 1500m, one-mile races and combined events over the same distances. The regulations require any athlete who has a Difference of Sexual Development (DSD), with levels of circulating testosterone (in serum) at five (5) nmol/L or above and who are androgen-sensitive should meet certain conditions in order to be eligible to compete.

The rules require that such athletes must be recognised at law either as female or as intersex (or equivalent), must reduce their blood testosterone level to below five (5) nmol/L for a continuous period of at least six months and must maintain the blood testosterone level below five (5) nmol/L continuously (whether she competes or does not compete) for so long as she wishes to remain eligible.
