I don't think genetic tests indicate hormone levels.
Contingent on being an elite athlete, XY and high testosterone will almost certainly go together, but people should be tested before they reach the elite level. The majority of women athletes (unsurprisingly) also support such testing.
But the genetic test can just be used as a screening and if it returns an anomaly then they can confirm with other tests.
People have to choose between exposing female boxers to significant risk by forcing them to fight biological males against their will, or using some form of sex screaming. Too many people want to think they can be inclusive while avoiding the acceptance that this forced women to be punched repeatedly by biological males and some will suffer life changing injuries as a result.
I haven't seen a single person in this thread accept that that is the certain result of their advocacy.
The following has recently been published in a scientific journal and is authored by numerous leading scientists in the field.
Fair and Safe Eligibility Criteria for Women's Sport [Scandinavian Journal of Medicine & Science in Sports]
The Paris 2024 Olympic boxing competition, featuring athletes with alleged male advantages in the female category, has reinvigorated controversy about eligibility criteria for women's sport. Recently, in this journal [1], we explained how endogenous testosterone production during male development leads to performance advantages arising from well-established sexbased differences in body size, muscle mass, endurance, speed, strength, and power. These physical advantages are so large that they necessitate a separate and protected female category that excludes male advantage to ensure fair and safe competition for female athletes. The unfortunate developments in the 2024 Olympic Games compel these matters to be revisited.
During press conferences at the 2024 Olympic Games, the International Olympic Committee (IOC) invited solutions to address eligibility for women's sport. We take this opportunity to propose our solution, which includes: (a) recognizing that female sport that excludes all male advantage is necessary for female inclusion; (b) recognizing that
exclusion from female sport should be based on the presence of any male development, rather than current testosterone levels, (c) not privileging legal “passport” sex or gender identity for inclusion into female sport; and (d) accepting that sport must have means of testing eligibility to fulfill the category purpose.
.. there is ample evidence that biological sex is a crucial differentiator in ensuring fairness and influencing safety for female athletes [1]. The participation of male-born competitors (e.g., transgender women) and athletes with certain XY DSDs in female sport is a growing concern. These athletes experience male-typical development from testes producing testosterone, with resultant physiological differences creating athletic advantages and safety risks [4–6], even in athletes with XY DSDs who might have been observed as female at birth.
The ethical failures of sports federations in the past cannot be allowed to obstruct accessible solutions to such an important issue in women's sport. The ethical framework that governs modern genetic testing is thorough and, importantly to overcome the shortcomings of the past, it emphasizes individual consent, confidentiality, and dignity.
Current technology enables a screening procedure for “sports sex” that involves a simple cheek swab to determine sex chromosomes. This screen can be performed reliably and quickly and should be done in duplicate to ensure reliable results. The results of this sex chromosome screening should be used to indicate the need for follow-up tests as part of standard medical care, including counseling and psychological support as part othe ongoing duty of care to the athlete. This will permit greater understanding of a potential medical condition, but also allow for an evidence-based assessment of male advantage in sport [5]. However, to preserve confidentiality and dignity,
athletes must be screened early—perhaps when they first register in the female category in an affiliated competition and before they are thrust into the global spotlight. This would prevent the individual targeting and unsolicited public scrutiny that has occurred numerous times, most recently in the 2024 Olympic Games.
