The Danish Curling Federation (DCF) claimed the positive test came as result of her trying to fall pregnant as she has polycystic ovary syndrome (PCOS), which causes an imbalance in hormones.

Simonsen took an herbal remedy in a bid to try and get pregnant, according to the DCF, who insist the substance “was not taken with performance in mind”.

The organisation also said that it will not affect the Danish team’s fourth-place result at last year’s European Championships.

The 31-year-old, a World Junior Championships bronze medallist in 2006, returned a positive test following the event on home ice in Esbjerg last November.

Simonsen, who represented Denmark at the 2014 Winter Olympics in Sochi, has been provisionally suspended until the matter has been resolved.

The case has now been passed to the WCF independent panel.

“I am disappointed and hopefully this will prove to be an innocent error but obviously we must leave this in the hands of our independent panel,” Caithness, President of world curling’s governing body since 2010, told insidethegames.

“Doping isn’t really a part of our sport as we have only had a couple of cases and long may that continue.”

Simonsen’s case provides a rare failed doping test in curling, with the most high-profile incident coming in 2013 when Canadian World Championships silver medallist Matt Dumontelle was given a two-year suspension for testing positive for banned substance methandienone, an anabolic steroid.
