Following a survey issued by the IWF to other International Federations (IFs) regarding transgender policy, Dörr informed the Association of Summer Olympic International Federations' (ASOIF) medical and science consultative group of the results.

The survey found that IFs believe there should be a single policy, drawn up by the International Olympic Committee (IOC), which can be implemented by all in a bid to level the playing field in certain sports.

According to the IWF, the presentation was "well received and forwarded to the IOC" in order to assist with updates to their guidelines.

A transgender weightlifter from New Zealand eased to victory in a women's competition in Australia in March.

Laurel Hubbard destroyed the field in the over-90 kilograms field at the Australian International in Melbourne.

Hubbard, who was born Gavin until she transitioned, took the gold medal with ease which put her in line for possible selection to New Zealand's 2018 Commonwealth Games squad.

She lifted a combined total of 268kg, 19kg more than Samoa's Iuniarra Sipaia, who finished second.

Australia's Kaitlyn Fassina came third with 223kg.

Hubbard passed the IOC's criteria for transgender athletes after proving her testosterone levels stayed below certain levels in the 12 months leading up to the meet. 

However, her win attracted criticism from opponents who claimed it was not fair to have a transgender athlete in the female category. 

The IOC requires an athlete to demonstrate that "her total testosterone level in serum has been below 10 nanomoles per litre for at least 12 months prior to her first competition".
