(SOUNDBITE) (English) IAAF PRESIDENT, SEBASTIAN COE, TALKING ON THE IAAF-CASTER SEMENYA RULING, SAYING: "I think this is pretty straightforward and it's very straightforward for any international federation in sport.
Athletics has two classifications, it has age, it has gender.
We are fiercely protective about both and I'm really grateful that the Court of Arbitration has upheld that principle." 3.
REPORTER ASKING A QUESTION: "CAS (Court of Arbitration for Sport) raised issues about the evidence provided for the 1500 metres and the mile.
Would you consider delaying the ruling or the implementation as regards to those particular events?" 4.
(SOUNDBITE) (English) IAAF PRESIDENT, SEBASTIAN COE, SAYING: (WIDE OF NEWS CONFERENCE) "No." STORY: IAAF President Sebastian Coe said on Thursday (May 2) that he's "really grateful" to the Court of Arbitration for Sport (CAS) after the ruling against Olympic champion Caster Semenya.
Speaking at a news conference in Doha, Qatar, ahead of the Diamond League season-opener, Coe expressed his gratitude to CAS after it chose to uphold new IAAF rules which attempt to restrict testosterone levels in female runners.
Double Olympic 800-metre champion Semenya lost her appeal after challenging the IAAF rules, and the South African, as well as other athletes with differences in sexual development (DSD), must now take testosterone-reducing medication in order to compete in some track events - from 400 metres to the mile - or switch to other disciplines.
Coe said there would be no delay in implementing the new regulations, despite Cas suggesting it had "serious concerns as to the future practical application" of them.
Athletics South Africa (ASA) has said it was "reeling in shock" over the CAS decision in a show of public backing for Semenya.
The 28-year-old athlete is eligible to compete in Doha and can make an appeal against the Cas ruling within the next 30 days to the Swiss Tribunal Courts.
Semenya supporters have been urging the athlete not to quit over the ruling.
Coe also lauded the new Diamond League format - set to be introduced in 2020 - as "brave and courageous" ahead of this season's opener in the Qatari capital on Sunday (May 5).
The 5,000 and 10,000 metre races will be scrapped with the intention to make athletics more enjoyable and compelling for supporters, with meetings set to be no more than 90 minutes long from next year.
The current 32 track and field events that make up Diamond League meets will be reduced to 24 with many track events set to take place in city centres in an attempt to connect fans.
There will be one meeting a week across a 13-week span in the summer.
