[2] Luk lived as a male for 36 years, and now identifies and lives as a woman,[2] after changing her sex characteristics from intersex to female through gender-affirming surgery, upon doctors' advice to undergo the surgery because her type of PAIS would most likely have caused cancer.

When Luk was born, the doctor found that she was intersex, with organs resembling testicles and a penis.

Luk was deemed male and underwent more than 20 operations between the ages of 8 and 13 to construct a urethra – the duct that conducts urine from the bladder.

News records state that Luk[4] was the only surviving person among the seven people who were operated on as children at Hong Kong's Kwong Wah Hospital in the 1970s to "fix" their anatomies.

[7] Luk has been invited to various international and local events,[8][9] including the United Nations meeting in Thailand,[4][10] to speak on the issue of intersex people and their rights.
