The 18-year-old crossed the finish line in an official time of 21.81 seconds, just behind Jamaican sprinter Elaine Thompson-Herah.

Due to her high levels of testosterone, Mboma is not allowed to compete in some events, but she was cleared to go in the 200m.

However, Urbas has now spoken out over her impressive performance, saying she should take a test.

The 44-year-old said: "I would like to request a thorough test on Mboma to find out if she definitely is a woman.

"The testosterone advantage of Mboma over other participants is seen with the naked eye.

"In construction, movement, technique, at the same time as speed and endurance.

"She has the parameters of an 18-year-old boy, at that age my PB was 22.01 and she has done it in 21.97 in Tokyo."

He went on to claim her hormonal levels are allowing her to surpass junior world records in her event.

Urbas added: "With progression and improvement in her technique, she will soon drop to 21.00 seconds in 200m and 47.00 seconds in the 400m."

Mboma and her compatriot Beatrice Masilingi, who came sixth in the final, are classified as Difference of Sexual Development athletes.

This is due to the fact the pair naturally produce more testosterone than other women.

World Athletics president Sebastian Coe said the pair's performance in the final 'vindicated' the decision not to allow them to compete in the 400m.

He said: "It was pretty observable that the last 30 or 40 metres were impactful.

"But, actually, I think that vindicated the decision about 400. If you are finishing a 200m like that, you extend the runway... That in a way supports the judgement that was made."
