The World Medical Association Sunday urged doctors not to enforce controversial new IAAF gender rules for classifying female athletes, warning that attempts to do so would breach ethical codes.

It follows South African runner Caster Semenya last week losing her court challenge against the International Association of Athletic Federations over plans to force some women to regulate their testosterone levels.
