The IOC has prioritised these male athletes since before the Sydney 2000 games. This is one of the papers they published about it.

"On-site gender verification has since been found to be highly discriminatory, and the cause of emotional trauma and social stigmatization for many females with problems of intersex who have been screened out from competition. Despite compelling evidence for the lack of scientific merit for chromosome-based screening for gender, as well as its functional and ethical inconsistencies, the IOC persisted in its policy for 30 years."
"The coauthors of this manuscript have worked with some success to rescind this policy through educating athletes and sports governors regarding the psychological and physical nature of sexual differentiation, and the inequities of genetic sex testing."
Specific dates leading up to the cessation of sex testing were:
1992 - Dr. Arne Ljungqvist becomes a member of the IOC and continue5 to date an educational program to inform the IOC about scientific and
ethical issues related to laboratory-based gender verification.
1996 - Most major professional medical societies have passed resolutions against chromosome-based gender screening in sports.
1996-1997 - IOC World Congress on Woman and Sport passes a resolution to abandon gender verification at the Olympics. Women's Sports Foundation
publishes a policy statement against blanket chromosome screening in support of IAAF model. The Norwegian parliament outlaws gender verification in sport. The IOC Medical Commission is unconvinced and the Atlanta Committee for the Olympic Games is contractually committed to on-site, laboratory-based, gender veritication of all female althletes competing in women's events.
1997-1998 - Arguments for and against change are presented to the IOC Athlete5 Commission by Professor A. Liungqvist and Dr. B. Dingeon, respectively. Prince de Merode and Dr. Hay argue for their original policy of blanket gender verification at IOC-sponsored sporting events. Athletes
Commission nonetheless calls for the discontinuation of the present system and rccommenda replacing it with a "reserve clause" system based on IOC Medical Commission intervention on an individualized basis, following scientific and ethical guidelines.
1999 - IOC Executive Board accepts unanimous recommendations of its Athletes Commission. Blanket gender verification screening of all female
athletes will not be conducted at the 2000 Millennia1 Games in Sydney, on a conditional basis for later review.
Importantly, for the 1996 Atlanta Olympics they surveyed the female athletes and found:
"At the time of testing, all female athletes at the Atlanta Games were offered a questionnaire written in both English and French asking whether in their view testing of females should be continued in future Olympics and whether or not
they were made anxious by the testing procedure. Of the 928 athletes who responded, 82% felt that testing should be continued and 94% indicated that they were not made anxious by the procedure. Forty-six athletes were made "anxious" by the testing requirements that preceded their competitive events.
No males were found to masquerade as females, and all females who were found to be SRY positive competed."
"Of the 928 athletes who responded, 82% felt that testing should be continued"
They didn't listen to female athletes it seems.
