Time for World Athletics to act! How can this be allowed?Of course more testosterone gives better performance at all distances .
Gender categories need to be completely eliminated from the sport as gender is an outdated concept for sports. Replace the gender categories with testosterone categories instead. This needs to be done ASAP by World Athletics.
The claim that "of course" naturally-produced "testosterone gives better performance at all distances" is only true of XY runners whose natural T comes from testes and who have the male physiology that allows them to make use of the T that their testes make like males customarily do, whether they're XY DSD like Niyonsaba or XY born with normal male urogenital anatomy like most blokes. But it's not true of XX females.
When doped on exogenous testosterone and other androgens, XX female athletes obtain physical attributes that improve athletic performance. However, higher endogenous, natural testosterone in XX females does not lead to, nor is it correlated with, better sports performance.
On the contrary, endogenous, natural T in XX females higher than the normal female range (0.06-1.68 nmol/L) is a sign of health conditions - PCOS, CAH, a cancerous tumor, pregnancy - that make it difficult for most XX female people to achieve or maintain the kind of tip-top physical fitness that competitive sports require, and which impair our ability to turn in impressive, record-breaking performances in track & field at any level of competition.
When the T (and other hormone) levels of 839 elite athletes competing in women's international track & field were measured in 2014, researchers (Bermon et al) found that elite XX athletes in track & field from around the world had T levels no different from sedentary women of the same age.
75% of the world's most elite athletes competing in women's international track & field who were tested had T under 0.91 nmol/L; 99% had T under 3 nmol/L. Some had T as low as 0.01 nmol/L.
By contrast, the athletes competing in women's elite international athletics who were known to be XY DSD - one of whom apparently was Caster Semenya - had T of 15.6-29.3 nmol/L, in the middle to the high end of the normal male range (7.7-29.4 nmol/L).
Moreover, the study found that XX "Female athletes involved in long-distance running consistently showed lower T and DHEAS concentrations when compared with athletes involved in events requiring strength, power, and speed..."
In short, the much higher levels of endogenous, natural T that XY males produce from their testes and respond to in male-typical ways is why XY males develop considerable sports advantages over XX female people, but higher endogenous T is not what gives XX females with ovaries and female physiology an edge in athletics competition over other XX females.
XX females produce and respond to natural, endogenous T very differently to how XY males do, whether or not the XY males are normally developed or were born with atypical anatomy due to XY DSDs. XY DSD athletes like Semenya and Niyonsaba competing in women's elite international athletics in recent years do not make or respond to T like XX female people do. These athletes make and respond to T the way XY males do.
For XY DSD athletes like Niyonsaba, Semenya and now Mboma, having natural T in the male range provides enormous performances advantages in women's competition. But an XX female athlete with natural T that high would have no chance of performing well on the track - she'd be far too ill to compete at all.
Since endogenous T plays a key role in the development and sports performance of XY males but not of XX females, why use this particular measure to classify all participants in sports? Why divide sports into categories using a yardstick that only suits the one-half of the population that has XY chromosomes, testes and male physiology? Why judge XX females by XY male standards?
