End of the road for Caster Semenya?

Female-identifying athletes with "Difference of Sexual Development (DSD)"-as coined by the IAAF-are also allowed to switch events without changing their body chemistry, say, for instance, to the steeplechase or the 5K".

The affected athletes - characterized in the regulations as "athletes with differences of sexual development" - will then have to maintain those lower levels to remain eligible for worldwide meets.

Last month the IAAF council approved a proposal to limit naturally produced testosterone for female competitors in distances from 400m to the mile with a view to implementing the rule by November. These distances, which synthesize the need for speed, power and endurance, are events in which raised testosterone levels can have the most profound influence on performances, the sport's top officials say.

South Africa's Caster Semenya celebrates winning gold in the woman's 800m final at Carrara Stadium during the Commonwealth Games on the Gold Coast. According to the organization's press release, most women's naturally occurring testosterone level is 0.12 to 1.79 nmol/L, while the typical male range is 7.7 to 29.4 nmol/L.

The International Association of Athletics Federations believes its new rules will "preserve fair and meaningful competition in the female classification" because women athletes with high testosterone have an advantage of up to 9% over women with normal levels of testosterone.

People call it sexist, racist but at the end of the day I would not be surprised if Caster Semenya - after this whole ordeal reduces her testosterone levels - still runs very well and wins medals because as I said it is not a key determinant. We wish to place on record that Caster Semenya has never engaged in any performance enhancing activities and any enhanced testosterone levels are due exclusively to her genetic make up, ' he said.

Athletics South Africa said: "Athletics South Africa has taken note of the new classification for females".

From November 1, the IAAF will limit entry for all global events from 400 meters through the mile to women with testosterone levels below a specified level.

She is also a double 800m Olympic gold medallist. By 2011, the IAAF put a limit on testosterone levels in female athletes.

It pointed to their latest research which showed there is a performance advantage for females with higher testosterone over the track distances.

Katrina Karkazis said: "Lowering testosterone can have serious lifelong health effects".

Semenya said: "If we still have speed in the 800m then we will still continue with the 800m". "When you walk out of your apartment, you think about performing".
