@WorldAthletics time for a periodic review of the DSD regulations which currently restrict 46XY female athletes who have testes & testosterone levels in the male range (7.7 - 29.4nmol/L) currently only restricting participation in events over the 400m-1500m.
Thread 1/
The performance benefits of testosterone do not discriminate between running distances.
On average males have a performance benefit of 11.2% (± 1. 25) across all running events & 19.0% (± 2.57) for all jumping events.

The gender gap exists across all running distances as shown by Thibault et al (2010) study showsthe smallest margin in running events of 6.5% in the 100m but the largest difference 13.96% I the 4x100m.

3/
The gender gap in performance is present across all world records is 10.0% ±2.94 between men & women for all events.
The gap ranges from 5.5% in 800m freestyle, 7% for speed skating, 8.7% cycling, 10.7% in running, & 18.8% in long jump.
Testosterone does not discriminate.
4/
The #Tokyo2020 #Olympics witnessed two extremes of DSD competing in running events.
Mboma & Masilingi in the 200m & Niyonsaba competing in the 10,000m.
5/
On 2nd July it was reported Mboma & Masilingi both only 18 were illegible to compete in the women's 400m. This was reported July 20 days prior to the start of the Tokyo Olympics.
Both Mboma & Masilingi were able to qualify for the Tokyo Olympics in this short window.
6/
Mboma won the Olympic silver medal over the 200m at the age of 18 after running just three 200m races prior to the Olympics.
Masilingi also 18 finished 6th in the 200m final.
7/
On the opposite end of the spectrum Niyonsaba who won the silver medal at the Rio Olympic 800m qualified for the Olympics in both the 5,000m & 10,000m.
She finished 5th in the 10,000m setting a National a Record of 30.41mins.
8/
The ability of some DSD athletes to transition between race distances is indicative of a performance advantage.
What other athlete in history has won an Olympic medal in the 800m with a range of finishing 5th in the 10,000m?
Time for World Athletics to review their policy.
Unfortunately for fair sport for female athlete's discrimination against DSD athlete's is required as stated by CAS.
