Some elite male athletes had testosterone levels in the female range. At the 1968 Grenoble Winter Olympics, officials instituted a check based on a lottery system; one-out-of-five female athletes underwent the control. But yet again, the physical appearances of female athletes convinced sport authorities that unfairness plagued women’s sport. Therefore, it is logical to use testosterone levels as the distinguishing factor. The new regulations will apply to middle distance track disciplines at international competitions only, and thus not to all events. Sporting events that rely on strength, endurance, and speed favor men’s athleticism over women’s physical abilities. But the case of Spanish hurdler Maria Martinez-Patino, who was unfairly thrown off the Olympic team after a chromosome test in the mid-1980s, led the IAAF to instead consider testosterone levels when deciding who was eligible to compete as a woman.

Men and women produce testosterone, but men generally produce much more.Under the rules, the IAAF would initiate a three-stage medical examination process if it suspected a female athlete had hyperandrogenism. It ordered the rules to be shelved until the IAAF could provide evidence to show there was a clear difference between male and female testosterone levels, and how big an advantage the extra testosterone gave hyperandrogenic women.Freed from the testosterone regulations, Semenya could break the 33-year-old world record in the 800 meters at the Olympics in Rio, South African sports scientist Ross Tucker said. Experts for Chand also showed that the dividing line between men and women when it came to testosterone wasn’t as clear as the IAAF suggested. But the case of Spanish hurdler Maria Martinez-Patino, who was unfairly thrown off the Olympic team after a chromosome test in the mid-1980s, led the IAAF to instead consider testosterone levels when deciding who was eligible to compete as a woman. There are various forms, but the one the IAAF regulated was hyperandrogenism in intersex women that led to them having testosterone levels that were much higher than the average for females.
People with hyperandrogenism tend to have testosterone levels in this male range, with an average of 18.3 nanomoles per liter. Ritzen also disagreed with Holt and van Anders that overlap exists between male and female levels of testosterone. Hyperandrogenism is a medical condition which causes a person to produce high levels of hormones. STELLENBOSCH, South Africa (AP) — In the wake of the Caster Semenya sex-test scandal at the 2009 world championships, track and field’s international governing body introduced contentious rules making women with a condition that caused them to produce high levels of natural testosterone ineligible to compete until they artificially lowered those levels.The IAAF’s hyperandrogenism regulations, imposed in 2011 and applied to Semenya and others, were criticized as unethical, discriminatory and against the Olympic charter, and without scientific backing.
PCOS, which is a mild form of hyperandrogenism, is associated with an anabolic body composition including more muscle mass than in non-PCOS women. It ordered the rules to be shelved until the IAAF could provide evidence to show there was a clear difference between male and female testosterone levels, and how big an advantage the extra testosterone gave hyperandrogenic women.Freed from the testosterone regulations, Semenya could break the 33-year-old world record in the 800 meters at the Olympics in Rio, South African sports scientist Ross Tucker said. Other factors, such as affluence, height, and training also come into play.Second, Chand posited that medical science is incapable of distinguishing testosterone thresholds for men and women; hence, the 10 nmol/L division point is arbitrary and inaccurate.

Part of the evidence for the CAS’s decision stems from a study by Stéphane Bermon, MD, PhD, from the Université Côte d’Azur, Nice, France, and colleagues who sought to determine how hormones affected the performance of track and field athletes competing in the World Championships in South Korea and Russia in 2011 and 2013, respectively.There were a total of 2127 observations included in the study. There are various forms, but the one the IAAF regulated was hyperandrogenism in intersex women that led to them having testosterone levels that were much higher than the average for females. To combat this supposed injustice, the IAAF and IOC introduced regulations on hyperandrogenism.In 2011, the IAAF and IOC targeted “suspicious” female athletes through hyperandrogenism testing.

It is well established that men overall have a competitive advantage over women in athletics.

On July 24, 2015, after four months of consideration, the CAS permitted Chand’s return to competition.
