IAAF Policy as of Jun 2019

IAAF policy requires DSD (Disorders of sex development) athletes to reduce testosterone to less than 5 nmol/L for events between 400m and 1 mile.

Standard ranges:

Most females (including elite female athletes) have low levels of testosterone circulating naturally in their bodies (0.12 to 1.79 nmol/L in blood); while after puberty the normal male range is much higher (7.7 – 29.4 nmol/L) (source)
