The new regulations about hyperandrogenism will compel female athletes whose testosterone levels are above a certain level, like South Africa's Caster Semenya, to take medication if they wish to continue participating in certain events.
"There is a performance advantage in female athletes with DSD (Differences of Sexual Development) over the track distances covered by this rule", Dr. Stephane Bermon, who works in the IAAF medical and science department, said in the statement.
"We want athletes to be incentivised to make the huge commitment and sacrifice required to excel in the sport".
Caster Semenya wins gold in the Women's 800m final during the 2016 Rio Olympic Games.
"As a federation, we will study the new regulations and compare them with the CAS (Court of Arbitration for Sport) recommendations to see if they are compatible and in line".
Nintendo names new CEO after Switch success
Another bright spot for Nintendo was the SNES Classic Edition , which Nintendo said "proved to be a hit in every region". Sales for the console are up to 17.79 million as of March 31, according to the company's latest earnings report .
Women with elevated testosterone must reduce their level for "six months (e.g., by use of hormonal contraceptives)" before being eligible to run, and maintain that lowered level. This means we need to be clear about the competition criteria for these two categories.
It's worth noting that Semenya is not almost as dominant in the 1500m as she is the 800m, and managed just the bronze medal in the 2017 world final behind Faith Kipyegon of Kenya and Jenny Simpson of the United States.
Most females (including elite female athletes) have low levels of testosterone circulating naturally in their bodies (0.12 to 1.79 nmol/L in blood); while after puberty the normal male range is much higher (7.7 - 29.4 nmol/L). Caster has been subjected to vicious attack and the ANCWL will unapologetically defend her against this attacks even when are smuggled through back door as laws by IAAF.
Semenya‚ the Olympic and world 800m champion‚ was first placed in the spotlight in 2009 with the IAAF saying she had undergone a gender verification process.
Other athletes believe she has an unfair advantage because of the high levels of naturally occurring testosterone in her body.
Russian air defenses shot down a target over Syria
According to him, the S-300 Favorit modified complex can destroy all carriers, including missiles. "One thing should be clear". Israel responded by carrying out airstrikes in Syria , drawing anti-aircraft fire that shot down an Israeli warplane.
The IAAF said that from November 1, it will limit entry for all global events from 400 meters to the mile to women with testosterone levels below a specified level.
"The ANC will stand with Caster Semenya in yet another attempt by worldwide sport bodies to exclude and discriminate against her", the party said in a statement.
The new rule is slated to take effect in November and would effect athletes in the 400 meters to mile.
I think the IAAF is setting a kind of standard in terms of how they differentiate between men and women and what is acceptable.
