This is the current policy, I checked since I posted it yesterday and it is the current one.
Version 3.0, approved by Council on 23 March 2023, and coming into effect on 31 March 2023:
3* *Eligibility Conditions for Relevant Athletes
3.1 A "Relevant Athlete" is an Athlete who meets each of the following three criteria:
3.1.1 they have one of the following DSDs:
2.7.1.1 ensure that the information is accurate and complete; and
2.7.1.2 not provide any information in bad faith, to harass, stigmatise or otherwise injure an athlete, or for any other improper purpose.
3.1.1.1 5α-reductase type 2 deficiency;
3.1.1.2 partial androgen insensitivity syndrome (aka PAIS);
3.1.1.3 17β-hydroxysteroid dehydrogenase type 3 (17β-HSD3) deficiency;
3.1.1.5 any other genetic disorder involving disordered gonadal steroidogenesis; and
3.2 3.3 3.1.1.4 ovotesticular DSD; or
3.1.2 as a result, they have a concentration of testosterone of 2.5 nmol/L or more in their serum; and
3.1.3 they have sufficient androgen sensitivity for that testosterone to have a material androgenising effect.
3.2 To be eligible to compete in the female classification at a World Rankings Competition, and/or to have recognised any World Record performance in a competition that is not a World Rankings Competition, a Relevant Athlete must meet each of the following conditions (the "DSD Eligibility Conditions"):
3.2.1 they must be recognised at law (for example, in a birth certificate or passport) either as female or as intersex;
3.2.2 they must have continuously maintained the concentration of testosterone in their serum below 2.5 nmol/L3 for a period of at least 24 months; and
3.2.3 they must continue to maintain the concentration of testosterone in their serum below 2.5 nmol/L at all times (i.e., whether they are in competition or out of competition) for so long as they wish to retain eligibility to compete in the female classification at World Rankings Competitions and/or to have recognised any World Record performance in the female classification at a competition that is not a World Rankings Competition.
my bolding to highlight the testosterone and androgenisation clauses.
