About Me

Dr Lok is a trained Obstetrician and Gynaecologist (O&G) and enjoyed an extensive career in managing and delivering high-risk pregnancies and practicing as a general gynaecologist in his earlier career. He is now a full-time fertility sub-specialist and reproductive gynaecologist, having completed the critically acclaimed Certificate of Reproductive Endocrinology & Infertility (CREI) qualification, which is the highest qualification in fertility medicine that doctors in Australia can achieve.

CREI membership is strictly limited to those fertility specialists who can demonstrate at least 15+ years of dedicated training and patient care in fertility medicine. Although many specialists may provide care for infertility, fewer than 100 specialists across all of Australia and New Zealand have achieved the very special distinction of CREI (out of more than 2,000+ obstetricians and gynaecologists across all of ANZ). Learn more about CREI at the Australian and New Zealand Society of Reproductive Endocrinology and Infertility here.

Dr Lok also completed a dedicated PhD in Feto-Maternal Medicine, making him one of the most academically qualified fertility specialists in Australia.
