Major golf associations the Ladies Professional Golf Association (LPGA) and the United States Golf Association (USGA) published new guidelines on Dec. 4 under which male players who identify as transgender have to have undergone transgender treatment before puberty in order to be eligible to compete in key women’s tournaments.
Under the new policies, transgender players must prove they have not experienced any part of puberty beyond stage two of the Tanner scale—a tool used by health care providers to track development during puberty—or after the age of 12, whichever comes first.
