IAAF accused Semenya of running slow to mask hormone levels, documents show

Caster Semenya was accused by the IAAF of intentionally running slowly at times to mask her alleged advantage from elevated natural testosterone, according to recently released court documents.

Semenya angrily denied the accusation.

The exchange was included in 163 pages of court records from the South African runner's appeal of the international track body's testosterone rules at the Court of Arbitration for Sport in February. They were released in redacted form four months after the hearing after both parties agreed.

In the documents, the two-time Olympic 800-metre champion also described her "atrocious and humiliating" treatment before and after her first world championships in 2009. Just 18 at the time, she was subjected to two intrusive "gender-verification" tests without her consent, she said.

A gynecologist said the IAAF then pushed for the young Semenya to have surgery to cut off her testosterone. The gynecologist pushed back against the IAAF. Semenya reluctantly agreed to take hormone-suppressing drugs.

Here are some more details from the court documents:

Semenya's story

In witness statements, Semenya described extensively for the first time her experiences around the worlds, her first major championships, in Berlin a decade ago.

She said South Africa's track federation sent a gynecologist to perform tests that included an examination of her genitals and taking blood samples without telling her what they were for. After she won the world 800 title, the IAAF conducted more tests on the then-teenager at a German hospital. It was "an order by the IAAF" and she was given no choice, Semenya said.

It didn't stop there. Semenya agreed in 2010 to take hormone-suppressing medication — oral contraceptive pills — but only after the IAAF said she could only continue competing if she medically reduced her natural testosterone. Semenya was put on medication the year before the IAAF first introduced highly contentious testosterone regulations. She was still a teenager.

Greta Dreyer, a South African gynecologist treating Semenya, testified the IAAF "made it clear" at the outset that its "preferred treatment" was surgery. Dreyer said she resisted and said if Semenya should undergo any treatment it should be hormone suppression. The IAAF denies that any athlete is forced to undergo surgery under its rules but surgery is one of the treatments the world body recommends alongside oral contraceptive pills and hormone-blocking injections.

The treatment

Semenya took the oral contraceptives for five years from 2010-15 and said they caused a myriad of unwanted side effects: weight gain, fevers, a constant feeling of nausea and abdominal pain, all of which she experienced while running at the 2011 world championships and 2012 Olympics. A South African track team doctor said the medication also affected Semenya's mood and ability to train and she was "visibly depressed." The doctor, Philda de Jager, said the medication caused Semenya's metabolism to go "haywire" and she displayed symptoms of a menopausal woman.

During the treatment, Semenya said the IAAF also accused her of deliberately not taking the medication and manipulating her testosterone levels in the lead-up to major championships, something she also denied. She had to have two sets of blood tests every month and unannounced random blood tests over the five years. Her overall feeling, she said, was of being treated like a "lab rat" as the IAAF experimented with medically reducing athletes' testosterone.

'Biologically male'

The IAAF waited until the closed-doors hearing at sport's highest court in Switzerland to argue Semenya and other athletes with certain "differences of sex development" (DSD) conditions were "biologically male." Now 28, Semenya was born with the typical male XY chromosome pattern and a condition that results in male and female biological characteristics and testosterone higher than the typical female range. She was legally identified as female at birth and has identified as female her whole life.

She called the IAAF's "biologically male" assertion "deeply hurtful."
